<p>I have been wanting to learn about 3D printing a long time so I really want this site to succeed but I have no previous experience with the subject. </p>
<p>I was wondering how can I help the site at this early stage. I thought about asking about how to get started with 3D printing but SE explicitly discourages "easy" questions in the private beta.</p>
<p>What can newbies like me do for the site at this stage besides voting questions and answers?</p>

<h1>Vote!</h1>
<p>Private Betas love, love, <em>love</em> votes. Without votes, it's difficult to attain privileges, get rewards, and help push us out to public beta.</p>
<h1>Ask Questions!</h1>
<p>I know you said this:</p>

</blockquote>
<p>But here's the catch. "Easy" isn't defined. If you have an "easy" question, but it is specific, high-quality, and to the point, and you can show some effort in it, then, please, go ahead and ask it!</p>
<h1>Participate!</h1>
<p>You have a voice in our meta discussions as well. You also have the authority to suggest edits, to posts, tag wikis, and tag excerpts. They also get you +2 rep for each that is approved, which can help bring you more afloat. You can also give your opinion in scope, by casting close and reopen votes as well :)</p>

<p>I suggest browsing the regex tagged questions on this site and experiment with your own answers without peaking at the current ones. You don't need to post your answers, but I bet that sometimes you'll come up with answers that are worth publishing.</p>
<p>Three good things with this approach:</p>
<ol>
<li>You'll be working with real-world
problems.</li>
<li>You might learn stuff
about other programming languages as
you go. ('Tis always good to learn
new languages).</li>
<li>You probably will be
helping the world find good answers
to real world regex questions.</li>
</ol>

<h2>First; find a model!</h2>
<p>To print something you require a <strong>model</strong> (usually this is in STL format, look into websites called <a href="http://www.thingiverse.com" rel="nofollow noreferrer">Thingiverse</a> and <a href="https://www.myminifactory.com/" rel="nofollow noreferrer">MyMiniFactory</a> for examples). Once you have a model file, you need to make it readable for the printer firmware.</p>
<p>If you can't find suitable model, then you need to design a model yourself (or ask someone to do it for you) or adjust an existing model to suit your needs. "<a href="/q/740/">Good (preferably free) Beginner Software for Part Creation?</a>" is a good place to start.</p>
<h2>Second; use slicer software</h2>
<p>For a printer to be able to print the model, the model needs to be sliced into layers. These layers need to be printed at specific speeds, temperatures, etc. Search online and look at the filament packaging (usually the ideal temperatures are on the packaging) to find the ideal temperature for your filament. If you are not using the right temperatures, your print will most likely fail. Programs that are able to slice models are called <strong>slicers</strong>. The most popular free (and Windows compatible) slicers are <a href="https://ultimaker.com/en/products/ultimaker-cura-software" rel="nofollow noreferrer">Ultimaker Cura</a> and <a href="https://slic3r.org" rel="nofollow noreferrer">Slic3r</a> (or its <a href="https://www.prusa3d.com/slic3r-prusa-edition/" rel="nofollow noreferrer">Prusa distribution</a>).</p>
<p>The slicer produces a printer readable file called a G-code file (file filled with printer instructions for e.g. movement and heating). This G-code file can be sent to the printer using specific printer software (e.g. OctoPrint, Repetier-Host, etc.) but more common or simple is to put the G-code file on an SD card and print the file using the print menu on the printer LCD.</p>

<p>Experience. Solving something completely new is hard. The best way to solve problems is to try and find a problem that you've solved before, and that is similar, and adapt you solution to the new problem. So until you have experience with many different kinds of problems, it's hard to solve new problems that you come across. Visiting sites like this and reading questions and theirs answers are a great way of learning how others solved problems that they encountered.</p>
|
<p>What about a wiki - at least then other people can start to contribute.<br>
Otherwise they are just going to rely on you for the manuals</p>
|
<p>The question was migrated because the specific question of "<em>How do I tell if my Thermistors are 10k or 100k?</em>" is going to be best answered by users of Electrical Engineering SE. This also provides the SE network with more appropriate traffic based on the question at hand.</p>
<p>However, if the question of "<em>How can I change the thermistors settings in Marlin firmware?</em>" were to arise, then the question would be best suited here on 3D Printing. It might help both SE sites by providing links to each other's relevant questions for future users to reference.</p>
<p>If the question was something like "<em>How can I wire a hotend?</em>", this would be more appropriate here on 3D Printing SE as users in Electrical Engineering SE may not know as much about the topic compared to users in 3D Printing. This may be a poor example, but the idea is that there is strict correlation between <em>hotends</em> and 3D printing, whereas identifying thermistors is not a specific topic to just 3D printing.</p>
<p><strong>Update</strong></p>
<p>After reading a few posts on SE meta, <a href="https://meta.stackexchange.com/questions/10249/what-is-migration-and-how-does-it-work">this one</a> leads me to agree with you that this particular question may not have needed to be migrated. However, it exposes an important question of how we want to proceed with questions like this in the future? How far down the rabbit hole do we want to allow this site to go in this topic? I'd recommend others pitch in recommendations in answers here on what would be the appropriate topic in this case that can be applied to our <a href="https://3dprinting.stackexchange.com/help/on-topic">On-Topic</a> page so that it may be amended.</p>

<p>If its a personal project then take this as an opportunity to learn something new.</p>

<p>Help -> Welcome</p>
<p>That thing?</p>

<p>Stack exchange isn't a good platform for product recommendations in general, but a few sites allow it with a tight focus and control. Some that have allowed it in the past have decided to discontinue it for a variety of reasons.</p>
<p>I expect at the start we are going to get a lot of "What specific machine should I use" or "is there a 3D model of item X I can print".</p>
<ol>
<li>Should we allow product or part recommendations?</li>
<li>If we do, what can we do to make sure they are limited, rather than open ended questions where dozens or hundreds of answers would be different but correct?</li>
</ol>

<p>It should not be about merging of tags, rather we should come up with a proper terminology to identify the correct parts of the "build platform".</p>
<p>Basically, every printer consists of a frame with some sort of guide rails<sup>1</sup> moving a carriage. On this carriage a build surface is attached where the printer prints the print on; it is always the top of the stack. Note that this can be e.g. a moving Y-axis<sup>2</sup> or moving Z-axis carriage<sup>3</sup>. In some cases the carriage is missing and there is just a static mounting, then it's a platform instead<sup>4</sup>. It is basically irrelevant if the build surface is glued to the stack or removeable in some way or another.</p>
<p>Between the carriage and the build surface you can have have a stack of multiple elements: a structure or structures, a plate, plates or matts, insulation, etc. This <strong>whole</strong> assembly of elements make up the build platform, an example is shown below.</p>
<p><a href="https://i.stack.imgur.com/M3xCs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/M3xCs.png" alt="Proposed build platform terminology" /></a></p>
<p>Note that the linear support can be mounted in Y or Z direction. To tag the elements that make up the <em>build platform assembly</em>, a proposed solution can consist of the following terms for subassemblies:</p>
<ul>
<li><a href="https://3dprinting.stackexchange.com/questions/tagged/z-axis" class="post-tag" title="show questions tagged 'z-axis'" rel="tag">z-axis</a> or <a href="https://3dprinting.stackexchange.com/questions/tagged/y-axis" class="post-tag" title="show questions tagged 'y-axis'" rel="tag">y-axis</a> in combination with <a href="https://3dprinting.stackexchange.com/questions/tagged/carriage" class="post-tag" title="show questions tagged 'carriage'" rel="tag">carriage</a>,</li>
<li><a href="https://3dprinting.stackexchange.com/questions/tagged/platform" class="post-tag" title="show questions tagged 'platform'" rel="tag">platform</a> (to support printers that have a solid platform, e.g. Hyrel/Delta)</li>

<li><a href="https://3dprinting.stackexchange.com/questions/tagged/glass-print-surface" class="post-tag" title="show questions tagged 'glass-print-surface'" rel="tag">glass-print-surface</a>, <a href="https://3dprinting.stackexchange.com/questions/tagged/pei-print-surface" class="post-tag" title="show questions tagged 'pei-print-surface'" rel="tag">pei-print-surface</a>, <a href="https://3dprinting.stackexchange.com/questions/tagged/buildtak-print-surface" class="post-tag" title="show questions tagged 'buildtak-print-surface'" rel="tag">buildtak-print-surface</a>, etc. possibly augmented with the additional tag of <a href="https://3dprinting.stackexchange.com/questions/tagged/removeable-print-surface" class="post-tag" title="show questions tagged 'removeable-print-surface'" rel="tag">removeable-print-surface</a> or <a href="https://3dprinting.stackexchange.com/questions/tagged/magnetic-print-surface" class="post-tag" title="show questions tagged 'magnetic-print-surface'" rel="tag">magnetic-print-surface</a>.</li>
</ul>
<h2>Annotations</h2>
<ol>
<li>The rails often take the shape of rods and bearings, linear rails

<p>Typically, it's a better idea to wait before you try to get this kind of thing integrated.</p>
<p>Enthusiasm is great in a private beta, but for the early stages, direct that enthusiasm towards the Q&A. That's what'll get this site on its feet and into a successful public beta.</p>
<p>When the site's more stable and running nicely, then if there's a need (or want) for a plugin like this then the discussion about it can be had.</p>
<p>(On a tangent - if such a plugin is going to happen, it may well be down to SE's developers to get it done, which might make getting assistance from the people on this site difficult.)</p>

<p><strong>I say allow them.</strong> </p>
<p>To let you know what's out there, I work at <a href="http://hyrel3d.com" rel="nofollow noreferrer">Hyrel</a>. </p>
<p>Our printers can take <a href="https://www.youtube.com/watch?v=B0lvN-aPYHI" rel="nofollow noreferrer">spindle (milling) heads and additional axes</a>, and even <a href="https://www.youtube.com/watch?v=OceUiuTixPA" rel="nofollow noreferrer">diode</a> and <a href="https://youtu.be/FnYDoNkgOrI" rel="nofollow noreferrer">CO2 lasers</a>, and they all operate on the same gcode - we tell people E is for Emit as well as Extrude. We even have a <a href="https://www.youtube.com/watch?v=azFY-IqDB_0" rel="nofollow noreferrer">TIG welding</a> attachment. </p>
<p>We also run our <a href="https://www.youtube.com/watch?v=KIGeQmXNbNE" rel="nofollow noreferrer">Fadal CNC machines</a> on our printer software and firmware. </p>
<p>To many people this is a natural progression for a well-built 3D positioning system, and I encourage a broader definition.</p>

<h2>Yes, we should have a <em>three</em> vote close question review queue</h2>

<p>Things like Uservoice are great for generic suggestions and even finding bugs but they rarely answer your specific questions/concerns because that's not what they're there to do.</p>
<p>I also don't think they're that good at keeping a community together. Seriously. Pushing your users to another site where they have limited interest isn't in my handbook for cultivating communities. </p>
<p>You want:</p>
<ol>
<li><p>... to keep users on <em>your</em> site. Pop-in JS things are <em>okay</em> if branded well. But they might still have to log in and then there's the problem of...</p></li>
<li><p>... to keep them involved in problems they raise. If somebody raises feedback, raise some back at them. Trap them in the process. Ask them more questions about what they feel is right or why they feel something was wrong in the first place.</p></li>
<li><p>... to make giving feedback desirable. One of the reasons SO works so well is its points system. Points mean prizes (or status and power, here) and that's a great way to make people want to keep going at it. Some users will just care and incentives just sweeten the deal but most users won't really care enough without the prospect of benefiting from it some how.</p></li>
</ol>
<p>Just to skip back to the point that external services are too generic for directed feedback. As a developer, you sometimes need to ask specific questions to know when something needs changing and this feedback usually needs to be asked at very specific points, usually after a task.</p>
<p>Stick feedback questions <em>on your site</em> at the end of tasks. Eg if a user posts a new something-or-other, at the end of the process, stick an unmissable box in there, asking them how it was for them. You can ask relevant questions and you'll catch more problems because people have just done the task (opposed to them noticing your feedback tab 10 minutes later when they've forgotten half of it).</p>

<p>Here are few things to consider from my point of view</p>
<hr>
<p><strong>Printing technology</strong></p>
<p>The first thing that you need to take into account is printing technology. The most common[citation needed] right now is Fused Filament Fabrication. "Liquid light-sensitive resin" is being used in Stereolitography and Digital Light Processing - the SLA printers I found are less common and more expensive than FFF ones.</p>
<hr>
<p><strong>Price</strong></p>
<p>Need to decide on budget. You can buy printer for 60k USD and 400 USD. Quality is somehow linked to price but that's not a rule. You can buy a shitty printer for a lot of money.</p>
<hr>
<p><strong>Printing area</strong></p>
<p>Bigger allows you to print bigger things. You need to ask yourself how big things you really want to print. Remember that 3d printing is quite slow process - how often you will want to print big things that will take 60hrs+ to finish?</p>
<hr>
<p><strong>Printing materials</strong></p>
<p>What kind of materials you want to print with? Some materials will need higher temperatures so check the max hot-end temperature, some will require heated bed.</p>
<hr>
<p><strong>Assembled or DIY kit</strong></p>
<p>You can usually get kits for self-assembly cheaper than Ready-To-Print machines. However, it will require additional skills (i.e. soldering), tools and time to assemble. I am not sure if I would buy DIY kit for commercial use, but as an enthusiast I immensely enjoyed putting my Rostock Max together.</p>
<hr>
<p><strong>Reviews and reputation</strong></p>
<p>It is generally safe to buy printer that already has some users. Beware of new magical Kickstarter printers which will "change the 3d printing forever".
Reddit /r/3dprinting suggests that your new printer should meet 3 criteria:</p>
<ul>
<li>Printer passes the youtube test - has lots of youtube evidence that this particular printer is working.</li>
<li>Printer is out of the pre-order phase. This means that all pre-orders have been delivered.</li>
<li>Printer has a reputation of working well among current users.</li>
</ul>
<p>I found it to be a very good set of rules.</p>
<hr>
<p><strong>Upgrade capabilities</strong></p>
<p>That's very user-dependent, but this point is very important to me. I want to be able to change and improve certain parts of my printer. Check if you can switch the extruder, replace the hot-end etc. </p>
<hr>
<p><strong>Support</strong></p>
<p>I think one of the most important points. See if you can find a forum for your printer and how active community is. It will be immensely helpful if something goes wrong (and it will).
Also, company support is very important. What will happen if you need a replacement part or your printer will stop working altogether?</p>
<hr>
<p>This list is definitely not complete.
There are many more things that might be taken into account like configuration (delta or XY), multiple extruders, closed cases etc.</p>

<p>Given our successful private beta, soon after we go public it will be time for us to get our first crop of moderators, as explained in the <a href="http://blog.stackoverflow.com/2010/07/moderator-pro-tempore/">“Moderator Pro Tempore” blog post</a>:</p>
<blockquote>
<p>About a week into the public beta, we will seek out members who are deeply engaged in the community’s development; members who:</p>
<ul>
<li>Have a reasonably high reputation score to indicate active, consistent participation.</li>
<li>Show an interest in their meta’s community-building activities.</li>
<li>Lead by example, showing patience and respect for their fellow community members in everything they write.</li>
<li>Exhibit those intangible traits discussed in <a href="http://blog.stackoverflow.com/2009/05/a-theory-of-moderation/"><em>A Theory of Moderation</em></a>.</li>
</ul>
<p>Bonus points for:</p>
<ul>
<li>Members with participation in both meta and the parent site (i.e. interest in both community building and expertise in the field).</li>
<li>Area 51 participation, social network referrals, or blogging about the site.</li>
<li>Members who have already shown an interest or ability to promote their community.</li>
</ul>
<p>Candidates will be contacted and three of them will be selected to act as provisional Moderators until the community holds formal elections after the Beta period. Besides the normal abilities of a Moderator, they will:</p>
<ul>
<li>Have access to a special chat room where we will collectively work through the challenges of moderation and community self-policing.</li>
<li>Organize the process of selecting the site's attributes (domain names, design issues, the FAQ, etc.).</li>
<li>Rally community support and drive the mission of getting publicity for the site.</li>
</ul>
<p>Essentially, <strong>they will have the ear of the Stack Exchange team for anything we can do to help their sites succeed!</strong></p>
</blockquote>
<p>Although the moderators pro tempore will ultimately be selected by Stack Exchange, the purpose of this post is to seek out and propose candidates:</p>
<ul>
<li>Each nomination should be posted as an answer and it should include (at minimum) a link to the user's main and meta profile so we can check out their activity.</li>
<li>Self nominations are encouraged, step up if you feel you can help.</li>
<li>If you are nominated by someone else you should edit the answer and let us know if you accept or decline (explanation optional). If a nominee declines we will not delete the answer, as to not have someone else nominate them again.</li>
<li>If you are nominating someone else, please mark the post as Community Wiki before saving. Meta doesn't allow suggested edits, so your nominee may be blocked from accepting the nomination.</li>
<li>The nominations are not binding to Stack Exchange or the nominees. If you are being considered by Stack Exchange, you will get an official confirmation email at one point. </li>
<li>Before nominating someone or accept / decline a nomination, you should read <a href="http://blog.stackoverflow.com/2009/05/a-theory-of-moderation/"><em>A Theory of Moderation</em></a> thoroughly to find out what's generally expected from moderators.</li>
</ul>
<p>If you would like to learn more about the role, please drop into <a href="http://chat.stackexchange.com/rooms/34216/3d-printing">chat room</a> where you can ask about the role from other moderators (they appear with a blue name in the chat room). Another chatroom called <a href="http://chat.stackexchange.com/rooms/2691/the-assembly">The Assembly</a> was created specifically for users and moderators to discuss moderation activities, moderators from all over the network are there to answer your questions.</p>
<p>Once again, <strong>please don't hesitate to step up and self-nominate!</strong>. </p>

<p>Here are some consequences of your design. These may or may not be what you intended, but I point them out so that you're aware of them.</p>
<ul>
<li><p>A very Mojo-ful user who has been mostly quiet is not going to care at all about stepping on some toes, because they have a huge bank of Mojo from which to draw. This seems to go against your goal of limiting negative behavior.</p></li>
<li><p>Likewise, users who contribute absolutely nothing to your site still get Mojo just by virtue of having an account. But an otherwise valuable contributor who makes one off-color post that's disliked by the community will be silenced until he has enough Mojo to post again.</p></li>
<li><p>If someone has something very valuable to contribute, he has to make sure to have "reserve Mojo" at all times -- that is, he must ensure that he isn't at his posting limit. If he doesn't, he might lose the opportunity to say something useful that would earn him more Mojo.</p></li>
<li><p>The rate at which people can accrue Mojo is limited by the size of the community. If there are few people who are handing out Mojo, pretty soon they won't be able to hand out Mojo anymore, since there won't be anyone left who hasn't already received Mojo from them.</p></li>
<li><p>The oldest users will effectively become an invincible cabal whose ideas may define and shape your site. Since you can only reduce someone else's Mojo if they have fewer Mojo than you, these users can make statements your community vehemently disagrees with and have their Mojo ratings remain intact.</p></li>
<li><p>In general, by restricting the supply of Mojo, you have created an economic system in which people will probably be more hesitant to contribute to a discussion. They will need to more carefully weigh what they say, since a post that is disliked by the community may prevent them from speaking further if they get too much negative Mojo.</p></li>
</ul>
<hr>
<h3>Playing the system</h3>
<blockquote>
<p>Either show me how to play the system, or explain why you think it's impossible to play it.</p>
</blockquote>
<p>Suppose we define "playing the system" as "artificially changing the value or quantity of one's Mojo in ways you didn't intend". I would say your system is safe from artificial <em>inflation</em> of Mojo, but at the cost of stifling discussion that would have otherwise taken place. You must be able to make the following guarantees:</p>
<ul>
<li><em>Flow condition.</em> Mojo only "flows down"; it is not possible for a lower-ranked user to transfer Mojo to a higher-ranked user.</li>
<li><em>Creation condition.</em> It is difficult for users to take actions which can generate their own Mojo. Also, it is either impossible to make new accounts, or they carry such a heavy penalty that no one will want to do it.</li>
</ul>
<p>For example, if you cannot satisfy the creation condition, then malicious early users will simply make an army of new accounts. They keep a number of these new accounts in reserve, quietly accruing Mojo. They then use them as a "bury brigade" to drain Mojo of factions or ideas they disagree with. Although they will lose Mojo when they do so, the collective Mojo of the bury brigade will be constant as long as they don't go hitman on more than a single hated foe per day.</p>
<p>This is clearly not what you intended.</p>
<h3>Artificial deflation</h3>
<p>However, your system is not safe from artificial <em>deflation</em> of Mojo. To see why, imagine that users stream into your site to accept their invitations. Imagine a user, Mallory, with <em>k</em> Mojo points. Because Mojo can only flow down, there is no way for a user with <em>k</em> or fewer Mojo points can express their disagreement with Mallory. Only users with <em>k+1</em> or more Mojo can do so.</p>
<p>Mallory's reign of terror will continue unchecked unless there are enough users with <em>k+1</em> or higher Mojo. In fact, if Mallory is an early enough user, there may not be any users who have the power to reduce her Mojo. Indeed, because you've artificially made Mojo scarce, they may not <em>want</em> to burn a Mojo to express their opinion, given how precious each Mojo point is -- since that also weakens them and makes <em>their</em> opinions more vulnerable to attack.</p>
<p>In short, if there are enough (or maybe even just a few) Mallorys, you will be reduced to playing traffic cop and cleaning up after Mallorys instead of improving your site. The system can no longer be self-policing. Each Mojo point has now become worth much more than before, because people will see from the example of Mallory and her ilk that it is better not to burn a Mojo to open oneself to attack. Thus, Mojo deflation.</p>
<p>This is also clearly not what you intended.</p>

<p><strong>Yes!</strong></p>
<p>Absolutely. We need to reward good answers, and raise rep levels so suers can get moderation privileges when they rise to the normal public beta levels.</p>
<p>However, I think we should also downvote poor questions and answers. I haven't yet done so, partly because I've focused on rewarding the good posts. But downvoting is important, too.</p>
<p>What happened to me yesterday:</p>
<ol>
<li>I posted an answer (my first) to a question.</li>
<li>It was downvoted.</li>
<li>A user who may/may not have been the downvoter pointed out something I was wrong about.</li>
<li>There was a discussion in comments.</li>
<li>I deleted my answer.</li>
<li>I edited it.</li>
<li>There was continued dialogue with the user and another. I improved my answer even further.</li>
<li>Downvote was removed.</li>
</ol>
<p>I'm grateful to the downvoter, and to the comments. We need to establish what posts are good and bad in the site, and my original answer was not good. It was wrong in several points - and since the question was about <a href="https://3dprinting.stackexchange.com/questions/tagged/safety" class="post-tag" title="show questions tagged 'safety'" rel="tag">safety</a>, it was even more important for it to be correct. The feedback helped me to fix my answer, but if I had not done so, the downvote would have ensured that better answers went to the top.</p>
<p>We should definitely upvote. But downvoting is good, too. Downvoters don't have to comment - that's never the case - but comments certainly help. They helped me.</p>

<p>The most important lesson with regard to the design of any social computing is that community dynamics problems cannot be solved purely by technological means.</p>
<p>In other words, whatever the solution you implement, if you have users to whom getting points (or trolling or getting involved in flame wars or whatever other disruption) is more important that participating in the community, that is what they will do. </p>
<p>When designing the solution, you "simply" have to make sure that there are sufficient benefits (badges, entertainment, information, rewarding feedback) in place for people who aren't in it just for the points. Then, if you are very lucky, you will attract the right kind of people.</p>
<p>This may seem trite, but it is one of the most importat results of CSCW research (Olson and Olson, 2000): unless users are prepared to collaborate/play fair/be productive, then no amount of technology is going to solve that problem.</p>

<p>How about a site equivalent to Rent-a-Coder but for non-profits to solicit volunteer or low-cost developers for public service projects (i.e. make your question easy for the next guy in an equivalent situation). Given the current economic troubles, there are likely to be both a lot of unemployed developers and a lot of troubled non-profits (and a lot of demand for the various kinds of help those non-profits provide). Let's put them together.</p>
<p>Add a point system like StackOverflow so you can earn points by helping out non-profits with their web applications or whatever. Then go get some corporate sponsorship so that you can turn your points into credits at Amazon.com or some such. </p>

<p>Is it realistic or thought neccesary to develop a plugin/feature for this site, to automatically add a small info-box about a thingiverse link? An example of this is Apple's 3D touch technology. In theory, the plugin could recogize thingiverse links in questions and answers, replace the link with an image and the author/name of the project.</p>
<p>I'm also volunteering myself to help with this if there's interest. (Experience with Thingiverse API)</p>
|
<p>Typically, it's a better idea to wait before you try to get this kind of thing integrated.</p>
<p>Enthusiasm is great in a private beta, but for the early stages, direct that enthusiasm towards the Q&A. That's what'll get this site on its feet and into a successful public beta.</p>
<p>When the site's more stable and running nicely, then if there's a need (or want) for a plugin like this then the discussion about it can be had.</p>
<p>(On a tangent - if such a plugin is going to happen, it may well be down to SE's developers to get it done, which might make getting assistance from the people on this site difficult.)</p>

<p>I agree about the posting of the entire configuration file or G-code in a question is too big to fit, etc. What is really needed, and I've thought this for a long time, is a SE sanctioned version of PasteBin [functionality]. A persistent scrapbook/scratchpad site internal to SE (like the i.stack.imgur.com site) where <em>over-sized</em> chunks of code/configs/text can be pasted, without it being an external link (which carry the inherent risk of link death).

<p>It is very easy to ask questions that only tangentially involve 3D printing, such as:</p>
<ul>
<li><p>How do I drill a hole in a 3D printed part?</p></li>
<li><p>How do I paint 3D printed parts?</p></li>
<li><p>How do I sand, smooth, etc...?</p></li>
<li><p>How do I take a picture with a 3D printed camera?</p></li>
</ul>
<p>My last example is clearly not on topic, and the other examples aren't </p>
<blockquote>
<p>difficult, specific questions — the kind of questions pros and experts ask each other, not the kind of questions novices ask pros.</p>
</blockquote>
<p>However, the point is that it's very easy to involve 3D printing in a question that isn't about 3D printing. Drilling a hole in a 3D printed part is, for the most part, just like drilling one in wood. Such questions may be more suited for a general DIY/makers-type site.</p>
<p>On the other hand, there do exist 3D printing specific issues (for instance, low infill or delamination can be a problem when drilling in a (FDM) 3D printed part).</p>
<p>At what point does a question involving 3D printing become on-topic for our site? Should questions identify a specific issue ("I've tried drilling a hole, now my part has delaminated, what now?")?. Queries for general advice and best practice don't seem to fit the bill of being difficult and specific.</p>
|
<p>The dividing line of "tangentially off topic" is typically when the <em>actual</em> subject of the question being asked is only <strong><em>coincidentally</em></strong> adjacent to 3D printing. </p>
<p>Here is a <em>clear</em> example illustrating the "tangential issue:"</p>
<blockquote>
<p>I printed a crane mechanism in 3D. How much voltage must I apply to the motor to lift 150 grams?</p>
</blockquote>
<p>I see this type of thing all the time. Users will go to the mat arguing that they are printing in 3D, so their question is on topic. It is not. The actual <em>expertise</em> needed to answer this question is in electronics. With a question like this, the premise that the user <em>happens</em> to be printing in 3D is entirely coincidental to the actual issue. </p>
<p>The examples you cited above are a bit more iffy. I might argue some of them could (potentially) be on topic… if the issue of the material being printed in 3D is somehow germane to the problem. I actually don't know enough about the subject to say, so I'm only considering the possibility that it <em>is</em> relevant to this subject space.</p>
<p>Let's not be too quick to start barring questions that aren't explicitly about the physical process of 3D printing literally. There are a lot of <em>industry issues</em> that could be interesting to include here. It's probably better to <strong><em>wait for actual examples before trying to create a general rule around this issue.</em></strong></p>
<p>As a general rule for building this site, it is often better to wait for a preponderance of problems that occur <em>in actual practice</em> before we start seeking to create a lot of rules around hypothetical situations. Words to live by.</p>

<p>Almost all 3D printers have issues that could cause health problems.</p>
<p>FDM/FFF printers heat plastic to a temperature that may cause it to off-gas, and these byproducts may not be healthy.</p>
<p>SLA printers often use epoxies that may off-gas, or may be somewhat toxic prior to being cured.</p>
<p>Powder based printers can also off-gas, in addition to the powder itself presenting a possible hazard.</p>
<p>Many hobbyist and small companies dance around the problem, and suggest that the machines always be used in well ventillated areas. Professional machines often have filters and ventillation systems built in.</p>
<p>Rather than trying to find a "perfectly safe" 3D printer, spend some time deciding what you want to use one for, find printers suitable for your use, and expect that you'll need to provide reasonable ventilation for almost any printer. Plan your installation for that, and you should be able to make any printer safe for your required use.</p>
<p>If, however, you plan on setting up a printer farm with many printers, and plan to have yourself or others spend significant time operating them, I suggest you work with a health and safety professional and have them identify possible hazards and plan mitigation.</p>

<p>There are a lot of factors to 3D printing parts that work and fit together. </p>
<p>A lot of it will be discovered by trial and error, but let's try to put you on the right path. </p>
<p>First your material is what matters the most. Specifically their coefficient of thermal expansion, i.e. how much can the plastic change when heat is applied. PLA's coefficient is low compared to ABS, for example. Which is why the MakerBot can print without a heated bed, but it cannot print ABS with any success.</p>
<p>Here is a <a href="http://omnexus.specialchem.com/polymer-properties/properties/coefficient-of-linear-thermal-expansion" rel="nofollow noreferrer">list of coefficient of thermal expansions</a> by material.</p>
<p>What you want to do next is to print out a few test items and see for yourself. Below is an example of reality vs. expectation. As you can see the circle shrinks. It will never expand. So you will always make it bigger than you need. It is also good to note in this example below that the block itself is Larger than expected. The best solution is to not expect high tolerances and build a lot of flex into your designs.</p>
<p><a href="https://i.stack.imgur.com/v0e4Q.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/v0e4Q.png" alt="Example of thermal expansion"></a></p>
<p>Generally you want the hole size larger. If I wanted a 4 mm minimum hole, then I would likely make it 5+ mm.</p>
<p>The best thing you can do is print out a tray and document how different the sizes are. Also, do the same with a print of various peg sizes. Below is an example of such a tray.</p>
<p><a href="https://i.stack.imgur.com/1jmQn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1jmQn.png" alt="Example of a print of various holes"></a></p>

<li><p>A <a href="http://reprap.org/wiki/Lubrication" rel="nofollow noreferrer">RepRap Wiki article</a> on different lubricants in regards to 3D printers. Most people use silicon lube for parts to my knowledge. Again, it depends on your material. </p></li>

<p>It is definitively possible to do what you want, but your questions are samewhat problematic:</p>
<blockquote>
<p>So, I need to know if it's possible to print that cylinder hard enough to work as an axis.</p>
</blockquote>
<p>"hard enough" is a mysterious quantity. What is the intended application? The load of the axis, the rotation speed, the medium in which the part will be in, its operating temperature... they all affect the answer.</p>
<blockquote>
<p>And what should be the gap size between the cylinder and the counter part's hole to rotate properly?</p>
</blockquote>
<p>Reading at the question and the comments, I think you may have the wrong representation model in your mind. There are four different concepts at work here:</p>
<ul>
<li><em>Accuracy</em> is the maximum dimensional variation between parts. </li>
<li><em>Tolerance</em> is the amount of random deviation or variation permitted for a given dimension.</li>
<li><em>Allowance</em> is a planned difference between a nominal or reference value and an exact value.</li>
<li><em>Clearance</em> is the intentional space between two parts.</li>
</ul>
<p>So: what you want to achieve for the object to rotate is to have at least some <em>clearance</em> once you have the parts printed. Therefore, you want to design your part with an <em>allowance</em> which is at least as much as the <em>accuracy</em>.</p>
<p>Note that a machine cannot produce parts with a tighter tolerance than its accuracy. So you must design your part with a <em>tolerance</em> equal or greater than your printer <em>accuracy</em>.</p>
<p>The correct number will therefore be entirely dependant from the specific printer you will be using. You can find out the specific <em>accuracy</em> of a printer by printing a <a href="https://www.thingiverse.com/search?q=Tolerance%20test&sa=&dwh=815ab32c4d0733c" rel="noreferrer">tolerance test</a> (I know, I know... why isn't it called "accuracy test"?)</p>
<p>See this <a href="https://3dprinting.stackexchange.com/a/5187/9134">unrelated answer</a> - from wich I took the above definitions - for learning more about the above and a concrete example.</p>
<blockquote>
<p>If it's is like 0.05mm, can I print that level of detail with a 3D printer too?</p>
</blockquote>
<p>I hope it is now clear why this question makes no sense: <em>clearance</em> is a variable which depends from <em>accuracy</em> (and the application), not the other way around.</p>
<blockquote>
<p>I can't add so much gap because I have really limited space</p>
</blockquote>
<p>This comment too is incorrect: the "gap" (clearance) can be very very small. You have to have the correct <em>allowance</em> in your design, and allowance will <em>not</em> intrinsically make a part larger.</p>
<blockquote>
<p>What hardware and material should I use to do this?</p>
</blockquote>
<p>Again: this is entirely dependent from your application (load, operating temperature, orientation, speed...)</p>
<p>A consumer-grade FDM printer (easy accessible, cheap and cheap to operate) will allow you to print a rotating part, a SLA/DLP printer (less common, toxic resins, more expensive to operate) will allow to print the same part with different materials and tighter tolerances...</p>
<blockquote>
<p>I don't worry about breaking, but it cannot be flexible</p>
</blockquote>
<p>Again: without an explanaton of the intended use (or the numbers associated to it) it's impossible to answer this comment conclusively. Resins tend to harden to more rigid solids, but you have thrown around tolerances as small as 0.05mm in your writing, and over 12mm of axis, that is a deviation of less than 0.5% from "perfectly straight". I'm hard pressed to think you will find a printable material with such a rigidity.</p>

<h2>First; find a model!</h2>
<p>To print something you require a <strong>model</strong> (usually this is in STL format, look into websites called <a href="http://www.thingiverse.com" rel="nofollow noreferrer">Thingiverse</a> and <a href="https://www.myminifactory.com/" rel="nofollow noreferrer">MyMiniFactory</a> for examples). Once you have a model file, you need to make it readable for the printer firmware.</p>
<p>If you can't find suitable model, then you need to design a model yourself (or ask someone to do it for you) or adjust an existing model to suit your needs. "<a href="/q/740/">Good (preferably free) Beginner Software for Part Creation?</a>" is a good place to start.</p>
<h2>Second; use slicer software</h2>
<p>For a printer to be able to print the model, the model needs to be sliced into layers. These layers need to be printed at specific speeds, temperatures, etc. Search online and look at the filament packaging (usually the ideal temperatures are on the packaging) to find the ideal temperature for your filament. If you are not using the right temperatures, your print will most likely fail. Programs that are able to slice models are called <strong>slicers</strong>. The most popular free (and Windows compatible) slicers are <a href="https://ultimaker.com/en/products/ultimaker-cura-software" rel="nofollow noreferrer">Ultimaker Cura</a> and <a href="https://slic3r.org" rel="nofollow noreferrer">Slic3r</a> (or its <a href="https://www.prusa3d.com/slic3r-prusa-edition/" rel="nofollow noreferrer">Prusa distribution</a>).</p>
<p>The slicer produces a printer readable file called a G-code file (file filled with printer instructions for e.g. movement and heating). This G-code file can be sent to the printer using specific printer software (e.g. OctoPrint, Repetier-Host, etc.) but more common or simple is to put the G-code file on an SD card and print the file using the print menu on the printer LCD.</p>

<p>This has inspired some discussion and I may be just splitting hairs, but I've always been confused by this strategy. The specific example I'm referring to is here: <a href="https://3dprinting.stackexchange.com/a/29/60">https://3dprinting.stackexchange.com/a/29/60</a></p>
<p>In many cases on SE, I see people post "Answers" that basically say "Don't do what you're doing. Instead you can get to your goal by doing this." While it is often helpful, this form of answer is the bane of my existence as a user of SE sites.</p>
<p>There are often cases when I am googling a difficult problem because I cannot do "alternative a" as suggested by the answerer. Then, I get to an SE question that asked about exactly the situation I am having. An answer of "Don't do that, do this instead" is upvoted, accepted, and the only answer. Thus, I am unable to solve my problem using SE. In other words, the Answer didn't apply to the question, and so SE led me down the wrong path.</p>
<p>Am I doing something wrong here? Is this an expected/accepted pattern? Or is this something I should go the route of downvoting? Or like the poster of the above answer suggests, flagging?</p>
|
<p>Sometimes, "don't try to do what you're trying to do" is the only valid answer, see e.g. <a href="https://meta.stackexchange.com/questions/66377/what-is-the-xy-problem">XY problem</a>.</p>

<p>Any overt form of censure on an existing user could lead to the forum equivalent of an arms race. One school of thought pushed on the SO podcasts is to flag the offending user and remove their posts from normal view, but include it when they (the bad user) are looking at the site. That way, they think the community is ignoring them and it makes flaming less fun. If the site isn't trying to stop them but their efforts at flaming are fruitless, they will likely just walk away. </p>

<h1>Vote!</h1>
<p>Private Betas love, love, <em>love</em> votes. Without votes, it's difficult to attain privileges, get rewards, and help push us out to public beta.</p>
<h1>Ask Questions!</h1>
<p>I know you said this:</p>
<blockquote>
<p>I thought about asking about how to get started with 3D printing but SE explicitly discourages "easy" questions in the private beta.</p>
</blockquote>
<p>But here's the catch. "Easy" isn't defined. If you have an "easy" question, but it is specific, high-quality, and to the point, and you can show some effort in it, then, please, go ahead and ask it!</p>
<h1>Participate!</h1>
<p>You have a voice in our meta discussions as well. You also have the authority to suggest edits, to posts, tag wikis, and tag excerpts. They also get you +2 rep for each that is approved, which can help bring you more afloat. You can also give your opinion in scope, by casting close and reopen votes as well :)</p>
|
<p>Good idea? No.</p>
<p>Sometimes necessary? Yes.</p>
<p>Living in a world where you sometimes have to do things you know aren't a good idea? Priceless.</p>
<p>In general, you should always follow best practices. For everything else, there's kludges.</p>
|
<p>What is the problem? The “You’re Doing It Wrong!!” feeling is the essence of our existence. </p>
|
<p>Regarding the "invisible modification", there is technically a modification made multiple times by the user <strong>Song Khmer</strong> (now destroyed). This user was posting nonsense to your question by copying text from your question and posting it as an answer.</p>
<p>The reason you probably did not see this in the revision history is:</p>
<p>1) it wasn't a direct edit to your question</p>
<p>2) I believe only moderators can see deleted posts.</p>
<p><a href="https://i.stack.imgur.com/2VAiLs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2VAiLs.png" alt="enter image description here"></a> <a href="https://i.stack.imgur.com/2VAiL.png" rel="nofollow noreferrer">click here for full view</a> of deleted posts</p>
<p>I'm pretty sure that anytime someone posts an answer or edits your question, the post raises the modified flag. In this case, when the user was posting answers it would properly flag the post. But, the flag remained even after the answers were deleted (there were 3 answers).</p>

<p><strong>A big shout out to all of us for a successful graduation into private beta.
Let's make it a success now, and make sure we graduate into a full-fledged site.
So, this is one post which every user of a private beta site should read and act accordingly.</strong></p>
<p>This is a reproduction of a moderator's (Richard) <a href="https://hermeneutics.meta.stackexchange.com/questions/49">post on meta.hermeneutics.SE</a>; I believe it is very much applicable to this community as well. Richard wrote a post encouraging voting. I think this is a big issue because rep is the basis of our "economy", encourages (good) user activity, sorts out our content and makes the site look active. In particular <strong>Question Votes</strong> make the site look more active.</p>
<blockquote>
<p>I cannot state this strongly enough. Voting is <em>absolutely critical</em> to the formation of a healthy SE site. And this is never more true than in Private and early Public beta. </p>
<h3>Vote on Questions</h3>
<p>Voting allows the community to determine what topics are allowed and what are not. Voting shows what constitutes a well-formed question and what is unacceptable for this community.</p>
<p>If you need help formulating better questions, the blog post <a href="http://blog.stackoverflow.com/2010/10/asking-better-questions/">Asking Better Questions</a> might help you out. (Admittedly, it's geared towards the Stackoverflow crowd, but the philosophies there will help). Also, <a href="https://stackoverflow.com/questions/how-to-ask">How to Ask</a> directly from StackOverflow is an excellent resource.</p>
<p>Finally, I want to reiterate that <strong>Voting on questions is free!</strong> It doesn't cost you any reputation to to vote a question down. (Compared to answers:)</p>
<h3>Vote on Answers</h3>
<p>Voting on answers allows a dramatic increase in reputation. Like questions, it shows that you believe and support the answer provided. Also, vote answers up that you think are well worded and support the answer given. </p>
<p><em>You don't have to agree with an answer to vote it up!</em></p>
<p>To show that this is true, they've even created a <a href="https://3dprinting.stackexchange.com/help/badges/63/sportsmanship">badge for voting up competing answers (called "Sportsmanship")</a>.</p>
<p>If you think an answer is <em>useful</em>, vote it up. If you think an answer is <em>not useful</em>, vote it down. Either way, <strong>vote</strong>!</p>
<p>If you need help on writing answers, the meta post <a href="https://meta.stackexchange.com/questions/7656/how-do-i-write-a-good-answer-to-a-question">How do I write a good answer to a question?</a> will help you out.</p>
<h3>Final thoughts</h3>
<p>If people do not vote, there won't be enough reputation on this site for it to be promoted. Reputation is very important to a StackExchange site as it creates the groups of people capable of maintaining the site.</p>
<p>To show how critical it is, Jeff Atwood posted a blog article regarding this topic: <a href="http://blog.stackoverflow.com/2010/10/vote-early-vote-often/">Vote Early, Vote Often</a></p>
<h3>Encourage others to vote!</h3>
<p>Quoting RobertCartaino from chat:</p>
<blockquote>
<p>Vote, vote, vote. Encourage others to vote, vote, vote. On good content, leave signposts ("If you like this, please vote it up. It's important for the community!")-- in both meta and the main site. Maybe a few meta posts informing the users of the important of that type of participation. You are empowered a lot more than you know.</p>
</blockquote>
</blockquote>
<p>Don't upvote bad content (edit/suggest how to fix it instead) but make sure you remember to vote, especially for questions; if you learned something from an answer on a question, the question's probably worth an upvote too so others can find the good information.</p>
<p> [<img src="https://blog.stackexchange.com/images/wordpress/vote-here.jpg" alt="https://blog.stackexchange.com/images/wordpress/vote-here.jpg">]</p>

<p><strong>Yes!</strong></p>
<p>Absolutely. We need to reward good answers, and raise rep levels so suers can get moderation privileges when they rise to the normal public beta levels.</p>
<p>However, I think we should also downvote poor questions and answers. I haven't yet done so, partly because I've focused on rewarding the good posts. But downvoting is important, too.</p>
<p>What happened to me yesterday:</p>
<ol>
<li>I posted an answer (my first) to a question.</li>
<li>It was downvoted.</li>
<li>A user who may/may not have been the downvoter pointed out something I was wrong about.</li>
<li>There was a discussion in comments.</li>
<li>I deleted my answer.</li>
<li>I edited it.</li>
<li>There was continued dialogue with the user and another. I improved my answer even further.</li>
<li>Downvote was removed.</li>
</ol>
<p>I'm grateful to the downvoter, and to the comments. We need to establish what posts are good and bad in the site, and my original answer was not good. It was wrong in several points - and since the question was about <a href="https://3dprinting.stackexchange.com/questions/tagged/safety" class="post-tag" title="show questions tagged 'safety'" rel="tag">safety</a>, it was even more important for it to be correct. The feedback helped me to fix my answer, but if I had not done so, the downvote would have ensured that better answers went to the top.</p>
<p>We should definitely upvote. But downvoting is good, too. Downvoters don't have to comment - that's never the case - but comments certainly help. They helped me.</p>

<p>That sounds suspiciously like my Stack Overflow reputation score.</p>
|
<p>I quite like what is done e.g. <a href="http://episteme.arstechnica.com/" rel="noreferrer">here</a>. If you look towards the bottom of the page, there's a piece of text "powered by eve community". If you click that text you get a small chunk of technical information.</p>
<p>To me, this is a nice tradeoff between having the (useful) information readily available (for bug reports, etc.) and having to have (unpleasant) technical jargon visible to users of the site.</p>
|
<p>In fact, <a href="https://stackoverflow.com/users/1">one of the people who created this site</a> made a <a href="http://www.codinghorror.com/blog/archives/000893.html" rel="nofollow noreferrer">post regarding this</a> on his <a href="http://www.codinghorror.com/" rel="nofollow noreferrer">blog</a> </p>
|
<p>First, accept the fact that problems with your app (code, usability, etc.) will be discovered.</p>
<p>Then, make sure you have a clear way for users to communicate with you (form mail, email, uservoice, etc.). The easier you make this the better. For example, there is a uservoice link on every page of SO.</p>
<p>One philosophy I strongly believe in: if it's confusing to your users, it's broken. Be willing to change your app (no matter how "beautiful" the design may be) if your users are confused or not liking it. This doesn't mean you have to cave on your decisions, just that you need to consider revisions to improve the user experience.</p>
|
<p>There is a whole lot in the literature on voting systems, and a good bit of game theory can be applied. The issue that's difficult is that it's inherently probabilistic; you pick certain patterns as indicating <em>probable</em> fraud, and detect or exclude them; by doing so, you also exclude the possibility that someone is voting that way for innocent, or at least non-fraudulent reasons.</p>
<p>Consider, eg, someone who reads my deathless prose, develops an instant man-crush on me, and goes through all my answers voting each one up. I've got more than 30 answers so it would take a few days. Now, by assumption, this isn't my reputation-whoring sock-puppet, it's a person who for their own reasons, however unwise, has devoting all their voting to me for days at a time.</p>
<p>Is this fraud? No, but it would be detected as, and probably treated as, fraud.</p>
|
<p>Make a FAQ page or a tutorial covering some of the basics, that will eliminate quite a lot of questions.</p>
|
<p>My understanding is that it is approximately the following from another <a href="https://stackoverflow.com/questions/24066/what-formula-should-be-used-to-determine-hot-questions">Jeff Atwood</a> post</p>
<pre><code>t = (time of entry post) - (Dec 8, 2005)
x = upvotes - downvotes
y = {1 if x > 0, 0 if x = 0, -1 if x < 0)
z = {1 if x < 1, otherwise x}
log(z) + (y * t)/45000
</code></pre>

<p>This site may attract questions such as</p>
<ul>
<li><p>Is it legal to sell 3D printed objects from a model repository?</p></li>
<li><p>Are 3D printed guns legal in my jurisdiction?</p></li>
<li><p>If my custom-built printer sets my house on fire, does the insurance cover it?</p></li>
</ul>
<p>Are such questions allowed on this site, or should they be redirected to a site dealing more commonly with laws?</p>
|
<p>Yes, such questions should be on-topic. There can be partial overlap in sites' scopes, and unique legal issues involving 3D printing can be addressed here. Users of this site are more likely to have specific expertise than users on a site that deals with laws more generally.</p>

<p>The tags <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> & <a href="https://3dprinting.stackexchange.com/questions/tagged/support-structures" class="post-tag" title="show questions tagged 'support-structures'" rel="tag">support-structures</a> are in fact referring to exactly the same thing!</p>
<p>Furthermore, the meaning of support can be interpreted differently (i.e. helping out).</p>
<p>I support renaming/merging the <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> labelled questions to <a href="https://3dprinting.stackexchange.com/questions/tagged/support-structures" class="post-tag" title="show questions tagged 'support-structures'" rel="tag">support-structures</a>. This implies that the <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> tag is removed and it could be reinstated at any time by new questions. Users with enough reputation can remove the <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> tag if it gets recreated and we could create a synonym later. </p>
<p>In my humble opinion, the best solution may be to rename <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> to <a href="https://3dprinting.stackexchange.com/questions/tagged/supports" class="post-tag" title="show questions tagged 'supports'" rel="tag">supports</a> and then make it a synonym for <a href="https://3dprinting.stackexchange.com/questions/tagged/support-structures" class="post-tag" title="show questions tagged 'support-structures'" rel="tag">support-structures</a>!</p>

<p>Food packaging needs to comply with regulations. One certification agency informing about these (and their service to certify for them) is <a href="https://www.tuv-sud.com/home-com/resource-centre/publications/e-ssentials-newsletter/food-health-e-ssentials/e-ssentials-3-2015/regulations-for-food-packaging-products-and-materials" rel="nofollow noreferrer">TÜV Süd</a>, another is <a href="https://www.saiglobal.com/Assurance/resource-library/Food-Safety/packaging_Brochure.pdf" rel="nofollow noreferrer">SAI global</a>. A summary of the GFSI can be found <a href="https://www.manufacturing.net/article/2014/07/compliance-food-grade-product-manufacturing" rel="nofollow noreferrer">here</a>. Inform yourself about the standards you wish to apply! The stack can not give legally binding answers.</p>
<h1><strong>No</strong></h1>
<p>The Ender 3 is not approved to produce food products (and not usable for them out of the box) for lack of certification. In the design it comes from the box, you need to replace a lot of parts for food rated ones:</p>
<ul>
<li>The whole print head/bed need to be swapped out for food rated parts due to the exact composition being not known. They might contain banned materials. As a result:
<ul>
<li>You'll need an all-metal hot end that can be taken apart for cleaning up to the standards if needed.</li>
<li>You'll need a food rated PTFE tube.</li>
<li>You'll need a stainless steel nozzle that complies with food grade manufacturing demands.</li>
<li>The extruder gear should be stainless steel as well.</li>
<li>You'll need to add some part to prevent filament shreds/flakes from the extruder to enter the print area as they might act as contaminants or carry germs.</li>
<li>Similar measures have to be taken for the wheels on the hot end carriage, as it might shred.</li>
<li>As you include a volume of air into the print, you are likely to be demanded to print under a protective atmosphere to make sure no germs are inside the print.</li>
<li>We do not know the composition of the build platform, so you'd need to replace the back surface with something that is food rated.</li>
</ul></li>
<li>You'll need to post-process your prints as smooth as possible, especially because of the small edges at the layer boundaries, which can and will act as spots where germs can grow.
<ul>
<li>This <em>can</em> be achieved with a material that is smoothable in some way.</li>
<li>Alternatively, a sealing lacquer/coating that is food safe might help here.</li>
</ul></li>
</ul>
<h1>Remember, safety first:</h1>
<p>Printed plastics that are rated for food are not necessarily food safe because of the quality or blend of the material. PLA and ABS can be made food safe, but that is usually <em>pure</em> material. We usually don't know what kinds of fillers or coloring is in our filament. The heating process might destroy the colors or fillers, which in turn might make it unsafe.</p>
<h1>Indirect manufacturing</h1>
<p>If you are stone set you want/need, you can use indirect manufacturing: you don't print the actual object, you print a mold that makes the actual object. Clay and other ceramics can be made food safe very easily and they can be shaped with plastic molds.</p>
<h1>Boxing</h1>
<p>There is also another way to facilitate food safety in a 3D printed container, and that is checking where the food will actually make contact. For a lunch box, that is the inside. We could line this inside with a food safe surface, for example placing a steel cup in our plastic cup-holder. Accessories like a cup holder or a decorative container for the actual food container do not need to adhere to the food packaging regulations themselves.</p>
<h1>Exposure time</h1>
<p>I know this is all looking at industrial food rated production. The <a href="https://all3dp.com/1/food-safe-3d-printing-abs-pla-food-safe-filament/" rel="nofollow noreferrer">Primer</a> given in the question does include a point about time the product gets into contact with the food - if there is just a short exposure, you might <em>get away</em> with it, but it doesn't make it certified food safe. Another good read in this regard is <a href="https://pinshape.com/blog/3d-printing-food-safe/" rel="nofollow noreferrer">this</a> short discussion about the Pros and Cons.</p>
|
<p>If the design was made from an artist and is not public domain, than you should not upload that scan without the (written) permission of the creator of the design. Espacially a scan of a decorative object will likely be protected, so costumers buy the original instead of printing itself or buy a printed version. If you would design a deco object and sell copies of it, you also don't want that others just scan it and print it.</p>

<p>I believe this question is asked on every private Beta... what should be the name of our chatroom?</p>

<p><strong>The Hotbed.</strong></p>
<p>Colloquially, "hotbed" generally refers to a center of activity. Here, it will have a double meaning (referencing the hot bed of a 3D printer.</p>

<p>Typically, it's a better idea to wait before you try to get this kind of thing integrated.</p>
<p>Enthusiasm is great in a private beta, but for the early stages, direct that enthusiasm towards the Q&A. That's what'll get this site on its feet and into a successful public beta.</p>
<p>When the site's more stable and running nicely, then if there's a need (or want) for a plugin like this then the discussion about it can be had.</p>
<p>(On a tangent - if such a plugin is going to happen, it may well be down to SE's developers to get it done, which might make getting assistance from the people on this site difficult.)</p>
|
<p>Why is the team choosing the name. Don't you have a manager? That's how organizations are supposed to work: if one level can't achieve the goal in a timely manner, escalate it up to the next level.</p>
<p>What a colossal waste of time!</p>
|
<p>I do spend a lot of time as well worrying about the names of anything that can be given a name when I am programming. I'd say it pays off very well though. Sometimes when I am stuck I leave it for a while and during a coffee break I ask around a bit if someone has a good suggestion.</p>
<p>For your class I'd suggest <code>VendorHelpDocRequester</code>.</p>
|
<p>Precise is more important. The initial developer or you could have left a comment afterward to explain the naming if it is not a term that can easily be found in a dictionary or generally known to the audience.</p>
|
<p>After further discussion within our working group, we ended up going with 'fieldset'. </p>
<p>Thanks for all the suggestions.</p>
|
<p>Well, <a href="http://stackoverflow.com">stackoverflow.com</a> is.</p>
|
<p>There is nothing wrong with naming your internal modules after your company; I always do this. 90% of my code ends up on CPAN, so it has "normal" names, but the internal stuff is always starts with <code>ClientName::</code>. </p>
<p>I'm sure everyone else does this too.</p>

<p>We currently have quite a few tags about filament:</p>
<ul>
<li><a href="https://3dprinting.stackexchange.com/questions/tagged/filament" class="post-tag" title="show questions tagged 'filament'" rel="tag">filament</a></li>
<li><a href="https://3dprinting.stackexchange.com/questions/tagged/plastic-filament" class="post-tag" title="show questions tagged 'plastic-filament'" rel="tag">plastic-filament</a></li>

<li>etc.</li>
</ul>
<p>I feel like we need to clean these up and make clear what we'll use each tag for.</p>
<p>Thoughts?</p>

<p>All filament used in 3D printing is thermoplastic filament, so plastic-filament and thermoplastic-filament are redundant.</p>

<p>Big batches need you to be time efficient - or use a method that uses little work. So my suggestions are mainly needing oversight. Keep a fire extinguisher and safety gear handy though!</p>
<h1>Melting together</h1>
<p>Most filaments are melting at or around 200 °C.</p>
<p>I recently got rid of my box of (PLA) waste material by putting them on a tray and melting them together in a standard kitchen oven at 200 °C for about 1-2 hours. The resulting plate of plastic destroyed all structure that could be identified. This plate can be then broken up or recycled without the risk to disclose any company secrets.</p>
<p>I suggest to use a baking paper under the filament to be molten or a teflon coated tray, as the filament will be REALLY sticky to a blank metal surface.</p>
<p>About 4 liters of broken prints resulted in approximately a 5x450x300 mm sheet. If you make sure that no filament can touch the heating elements, you can get rid of quite a lot of material in each batch.</p>
<p><strong>Don't do this with ABS</strong> and don't contaminate your food trays with plastic rests - use specially marked ones that are for disposal of prints only.</p>
<h3>Green destruction</h3>
<p>If you want to be green when destroying prints: <a href="https://insteading.com/blog/solar-cooker/" rel="nofollow noreferrer">a box solar cooker</a> with a glass lid easily runs at 200 °C, is decently cheap and runs all day on just a couple seconds of adjusting every hour or so. You have to set it up in an access restricted area, but as long as the sun shines, it runs pretty much for free. Just make sure to put the prints to be destroyed onto some kind of non-combustible carriers, like tinfoil or aluminium trays.</p>
<h2>ABS in Acetone</h2>
<p>If you use ABS, exposing it to acetone fumes for a short time (seconds to half a minute will smooth the surface. Give it some minutes can destroy the structure into a batch of plastic waste without heat that hardens as the acetone evaporates again, though complex structures might need as much as an hour. Dunking ABS into acetone results in pure chemical waste, that is just a waste of acetone.</p>
<p>To save acetone and a way to the chemical waste disposal, try this:</p>
<p>Put a batch of several prints into a large, airtight box that isn't made from ABS. Pour some acetone on a tray and add a paper towel to generate a consistent acetone atmosphere in the box. Make sure to keep the tray on the floor of the box but in a way so no print will fall into it. This should dispose of the prints by merging them into a huge lump within about an hour.</p>

<p>I thought about asking about how to get started with 3D printing but SE explicitly discourages "easy" questions in the private beta.</p>
</blockquote>
<p>But here's the catch. "Easy" isn't defined. If you have an "easy" question, but it is specific, high-quality, and to the point, and you can show some effort in it, then, please, go ahead and ask it!</p>

<p><em>Copied from chat</em></p>
<hr>
<p>I agree about the posting of the entire configuration file or G-code in a question is too big to fit, etc. What is really needed, and I've thought this for a long time, is a SE sanctioned version of PasteBin [functionality]. A persistent scrapbook/scratchpad site internal to SE (like the i.stack.imgur.com site) where <em>over-sized</em> chunks of code/configs/text can be pasted, without it being an external link (which carry the inherent risk of link death). That would be the correct solution, and I don't understand why that hasn't been set up. Seems odd to me.</p>

<p>You can basically use any machine that pulverizes your pellets into small pieces.</p>
<p><a href="https://www.3dhubs.com/talk/thread/how-make-your-own-filament-recycling-old-3d-prints-part-1" rel="noreferrer"><strong>One guy on 3dhubs, explained it in details.</strong></a></p>
<p>My conclusion is that you can recycle everything using this data gathered from research up in link there. </p>
<p>Also, you can use any plastic material and pulverize it into pellets (even from the bottles) and you can try to do this process. Only thing that matters is quality of product.</p>
<p>I was thinking about pellets from vinyl records. I bought one big collection before one year, and there was around 500-600 records that are completley useless. So, you can pulverize them and repeat the process, because process of making vinyl records and process of making bottles is completley different, and uses different kind of plastics. </p>
<p>So to draw a conslusion: everything depends on quality of pellets.</p>
<p>And to answer on your three questions:</p>
<blockquote>
<p>Is the quality comparable to typical off-the-shelf filaments? Put<br>
another way, with reasonable tuning can one produce filament that's<br>
good enough to use without a lot of frustration?</p>
</blockquote>
<p>No, it isn't Your filament would be lower quality if you don't get a great pellets.</p>
<blockquote>
<p>Does it require a lot of attention to tuning, monitoring, or other
details (which make it less worthwhile / more time-consuming)? Warning
of pitfalls to avoid is also welcome.</p>
</blockquote>
<p>Yes it does. Check the link up there.</p>
<blockquote>
<p>Are there useful things one can do this way, that are hard to achieve
with off-the-shelf filaments? For example, unusual materials; better
control of diameter, density, etc; or mixing one's own colors?</p>
</blockquote>
<p>Again, it all depends on type of filament you like to use. I wrote about plastic filaments.</p>

<p>It might seem that common 3D printer materials such as PLA and ABS should be capable of being autoclaved—unfortunately. However, although their melting temperatures are higher than autoclave temperature (typically 121ºC), their glass transition temperatures are below that limit so they can warp or undergo creep deformation.</p>
<p>Sterilization of numerous plastics is described <a href="https://www.industrialspec.com/resources/plastics-sterilization-compatibility/" rel="noreferrer">here</a>, with PLA, ABS, and PET all being described as "poor" for autoclaving. For each "good" material on that list, I looked for filament by Googling and consulting material guides from <a href="https://www.prusa3d.com/material-guides/" rel="noreferrer">Prusa</a> and <a href="https://www.matterhackers.com/3d-printer-filament-compare" rel="noreferrer">Matter Hackers</a>.</p>
<p>Polypropylene (PP) or acetal (POM, also known as Delrin) are the best choices. Filament is available for PEEK, PEI (ULTEM), FEP, PPSU, and PPS but these filaments are expensive (>$100/kg) and require high extruder temperatures (>300ºC).</p>
<p>In contrast, PP is about $50/kg and uses an extruder temperature of 254ºC; POM is similarly priced and uses an extruder temperature of 210ºC. Nylon (depending on the exact type) and HT-PLA may also be worth considering.</p>
<p>"High temperature" filaments are not worthwhile for this application. Again, they're expensive and, more significantly, do not work well with consumer-grade 3D printers. For example, the upper limit for a Prusa i3 MK3s is about 280ºC—the thermistor only is good up to that temperature. Higher temperatures would require swapping out sensors and modifying firmware and building an enclosure. <a href="https://forum.prusaprinters.org/forum/original-prusa-i3-mk2.5s-mk2.5-how-do-i-print-this-printing-help/can-i-use-pps-filament-on-my-printer/" rel="noreferrer">It's been done</a>. Printers designed for high-temperature filaments easily cost <a href="https://www.aniwaa.com/best-peek-3d-printer-pei-ultem/" rel="noreferrer">thousands of dollars</a>.</p>
<p>This question was previously asked on <a href="https://www.reddit.com/r/3Dprinting/comments/9l8gao/what_filament_would_hold_up_to_regular/" rel="noreferrer">Reddit</a> <a href="https://www.reddit.com/r/3Dprinting/comments/3caivh/question_about_autoclavable_plastic_for_3d/" rel="noreferrer">a few times</a> but this analysis is more comprehensive.</p>

<p>I use them for searching for my stack (C#, ASP.NET, WinForms etc). I have them set up in Launchy as shortcuts.</p>
<p>I have posted some thoughts ideas on my <a href="http://cantgrokwontgrok.blogspot.com/2008/09/stackoverflow-crackoverflow-or.html" rel="nofollow noreferrer">StackOverflow blog post</a> - feel free to comment on there if you like:</p>
<blockquote>
<p><strong>Search Support</strong></p>
<p>The search functionality is improving.
However, is it still limited (for
example, no OR search). It also has
limited filtering options. One major
problem for me is that it displays
searches the answers as well as
questions. So, you can end up with a
page of results that point to one
question (which may not help you). Tag
searching is also improving but still
limited and even misunderstood by its
creator (see the comments).</p>
<p><strong>Finding Your Stack</strong></p>
<p>I am a C# developer. I work on Windows
and ASP.NET applications. I know
nothing about Java, Python, Ruby and
the many other languages out there. I
can offer limited advice on
architecture and design. Now,
currently, it is bloody difficult for
me to find questions with the
appropriate tags so I can assist. I
propose:</p>
<p>"Smart Lists" - these should be lists that each user can create that
you can specify tags to search for.
For example, I could create three
"Windows" (which searches for items
tagged "C# WinForms"), "Web" (tagged
"ASP.NET") and Architecture (tagged
"architecture"). Now, a web developer
who works on the LAMP stack may have a
"Web" tab, but entirely different
tags.</p>
<p>I am currently getting around this by
having Launchy shortcuts set up for my
stacks.</p>

<p>When 3D Printing moves into public beta, you're going to want to get the word out. And fast! One of the best ways to advertise ourselves across the entire Stack Exchange network is through community ads. </p>
<h3>So what are these "Community Ads?"</h3>
<p>Graduated sites allow the community to advertise relevant products or services within the site, using a system where the community chooses what to advertise. You can find these posts on per-site metas. Hint: these posts have the <a href="/questions/tagged/community-ads" class="post-tag moderator-tag" title="show questions tagged 'community-ads'" rel="tag">community-ads</a> tag!</p>
<h3>Cool! What should the ad be like?</h3>
<p>There's a few requirements for these ads. Most notably,</p>
<ul>
<li>They must be 300px wide by 250px tall, or double for "retina" displays</li>
<li>There's a limit on file size of 150 kB.</li>
<li>The image must be hosted on i.stack.imgur (the Stack Exchange image hosting service).</li>
<li>Ads must be GIF or PNG (no animated GIFs).</li>
</ul>
<h3>What else should I know?</h3>
<p>To facilitate easy posting to other sites, make sure that the embedded image is of the following format:</p>
<pre>[![Tagline to show on mouseover][1]][2]
[1]: http://image-url
[2]: http://clickthrough-url
</pre>
<p>You can also include a message as a part of your answer with your own thoughts: why you chose some of the elements, and what sites the ads could potentially be posted to. Don't forget to critique each other as well!</p>
<p><strong>Happy Designing!</strong></p>

<p>As you may or may not know, this is the third iteration of a proposal site that covers 3D Printing. The first 2 made it to the beta phase, but did not graduate from the beta successfully:</p>

<p>Would it be acceptable to extract <code>good</code>/<code>relevant</code> questions out of these beta site question dumps and post them in the 3D Printing site?</p>
|
<p>If someone has a question from one of those older sites, they should go ahead and ask it. But a wholesale importing of content from elsewhere is not really a desirable way to build this site. </p>
<p>There is a lot of ownership and careful curation that goes with vetting the content of this site. Questions imported from elsewhere would always have that air of odd, forgotten legacy content back-dated and <em>anonymous</em> with no owners or real-time vetting at all. If someone posts another answer or asks for some followup to one of these questions, no one will receive the notification. Essentially, we would be loading this site up with a lot of questions asked and answered a long time ago without imparting any of the benefits of reputation, ownership, or experience into the community that is supposed to take care of it.</p>
<p>That's why we don't do it.</p>

<p>It should not be about merging of tags, rather we should come up with a proper terminology to identify the correct parts of the "build platform".</p>
<p>Basically, every printer consists of a frame with some sort of guide rails<sup>1</sup> moving a carriage. On this carriage a build surface is attached where the printer prints the print on; it is always the top of the stack. Note that this can be e.g. a moving Y-axis<sup>2</sup> or moving Z-axis carriage<sup>3</sup>. In some cases the carriage is missing and there is just a static mounting, then it's a platform instead<sup>4</sup>. It is basically irrelevant if the build surface is glued to the stack or removeable in some way or another.</p>
<p>Between the carriage and the build surface you can have have a stack of multiple elements: a structure or structures, a plate, plates or matts, insulation, etc. This <strong>whole</strong> assembly of elements make up the build platform, an example is shown below.</p>
<p><a href="https://i.stack.imgur.com/M3xCs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/M3xCs.png" alt="Proposed build platform terminology" /></a></p>
<p>Note that the linear support can be mounted in Y or Z direction. To tag the elements that make up the <em>build platform assembly</em>, a proposed solution can consist of the following terms for subassemblies:</p>
<ul>
<li><a href="https://3dprinting.stackexchange.com/questions/tagged/z-axis" class="post-tag" title="show questions tagged 'z-axis'" rel="tag">z-axis</a> or <a href="https://3dprinting.stackexchange.com/questions/tagged/y-axis" class="post-tag" title="show questions tagged 'y-axis'" rel="tag">y-axis</a> in combination with <a href="https://3dprinting.stackexchange.com/questions/tagged/carriage" class="post-tag" title="show questions tagged 'carriage'" rel="tag">carriage</a>,</li>

<p>Starting a new project without a thorough research of the available solutions and without taking into serious consideration the possibility to join an existing project, is something that the community should frown upon more emphatically. Maybe a programmer's education should include some discussion on the cost of effort duplication.</p>
<p>Having said that, experimenting with different approaches to solve the same problem is healthy, and once a programmer has some toy code, we should thank him for making it available to the public regardless of the existence of similar projects.</p>
<p>I think that the authors should seriously consider a merge if:</p>
<ul>
<li>one design has proven clearly superior to the other</li>
<li>one community is being more active than the other</li>
<li>both projects share the same ideas on future directions</li>
<li>the work required to merge the two codebases is feasible</li>

<p>When the site's more stable and running nicely, then if there's a need (or want) for a plugin like this then the discussion about it can be had.</p>

<h3>Additional points of note</h3>
<p>The stats above aren't really the be all to end all... there are a few other considerations that I came across here, <a href="https://robotics.meta.stackexchange.com/questions/1354/graduation-of-this-community/1355#1355">in this answer</a>, to <a href="https://robotics.meta.stackexchange.com/questions/1354/graduation-of-this-community">“Graduation” of this Community</a>:</p>
<ol>
<li>A number of 10k+ users ( <em>n</em> > 3 ) are required to access mod tools</li>
<li>A number of 3k+ users ( <em>n</em> > 10 ) are required to be able to fully vote</li>
</ol>
<h3>The final hurdle</h3>
<p>The main sticking point, according to this meta post on Ethereum, <a href="https://ethereum.meta.stackexchange.com/questions/474/congratulations-ethereum-is-graduating">Congratulations! Ethereum is graduating!</a>, is 10 questions per day, which we are a long way from, and seems to be the last remaining issue. A link (<a href="https://meta.stackexchange.com/questions/257614/graduation-site-closure-and-a-clearer-outlook-on-the-health-of-se-sites">Graduation, site closure, and a clearer outlook on the health of SE sites</a>) from the Ethereum meta post to Meta.SE states:</p>
<blockquote>
<p>When a site starts to consistently receive 10 questions/day, we’ll consider it for graduation.</p>
</blockquote>
<h3>No graduation, but losing the Beta label...</h3>
<p>Apart from graduation, SE management has recognised that small sites (with an active community) struggle to reach the 10 questions/day consistently. For sites that have been waiting to get out of Beta by graduation for 7-8 years, SE has decided to drop the Beta label. Please see <a href="https://meta.stackexchange.com/questions/331708/congratulations-to-our-29-oldest-beta-sites-theyre-now-no-longer-beta?cb=1">Congratulations to our 29 oldest beta sites - They're now no longer beta!</a>.</p>

<p>It's pretty manageable right now due to the low question rate, but I think maybe ~3% of all questions this site will get, forever, will be "what's the best printer" or "what printer should I buy" type questions. They're mostly coming from people who don't know enough about 3DP to articulate their requirements, so they're difficult to help and very unfocused. Is there a better way to handle this than locking them as they come up? </p>
|
<p>A good option would be to have several reference questions, such as "What to look for when comparing printers?" or "How to select a 3D printer?" to which we could redirect these users.</p>

<p>As you suggest yourself, ordering test prints of some model is one way to do it. </p>
<p><a href="https://www.3dhubs.com">3D Hubs</a> and <a href="https://www.makexyz.com/">MakeXYZ</a> allows you to get your model printed by hobbyists and small businesses for a fair price. Both sites also allow you to order prints based on printer type, which I believe is what you may be looking for.</p>
<p>On 3D Hubs, visit on of the <a href="https://www.3dhubs.com/trends">trend reports</a>, and select the printer you want a sample from. Similarly, on MakeXYZ, <a href="https://www.makexyz.com/3dprinters/">search local makers</a> for your desired printer.</p>

<p>You can learn a lot just by reading the forums. I'll just list a few that are quite popular...</p>
<p><a href="http://forums.reprap.org/" rel="nofollow">Reprap Forums</a> - Has a ton of information on DIY printers including build logs and posts dealing with many issues.</p>
<p><a href="http://www.soliforum.com" rel="nofollow">Soliforum</a> - Large user base with lots of information. Not sure what it's standing is now that Solidoodle is gone but I'm sure the forum will stick around.</p>
<p><a href="http://forum.seemecnc.com/" rel="nofollow">SeeMeCNC</a> - Support forum for SeeMeCNC, has a lot of information for Delta printers and also other printers.</p>
<p>There aren't many books that I know of...Make magazine has done a few issues on 3D printing that you could try to obtain. I'm not sure what your idea of building a printer is, do you want to design your own or follow someone's instructions and put one together? Designing one would require some basic hardware and engineering knowledge.</p>
<p>All that said, the best learning experience would be buying a kit and learning as you go. You'll never read in a book what you will learn from having your own printer.</p>

<p>This question is unfortunately, not a good fit for this site, as it stands, for as you say it is opinion based. However, it is great to see that you are getting kids into a relatively new technology (yes, I know it has been around for years, but it is still seen as new to <em>big media</em> and the general public). </p>
<p><strike>My answer doesn't provide you with any actual designs, as you asked for.</strike> However, just to add an idea or two that I have been thinking about recently, in order to engage kids:</p>
<ul>
<li><p>Have you thought about using 3D printing pens (as side projects to the main feature of the printer)? Although I'm not so sure that the fumes at such close proximity would be that great, unless using PLA. That really would show close up the additive process.</p></li>
<li><p>Also, there is a lot of useful sites to be found on <a href="https://www.google.co.th/search?q=T3d%20printing%20for%20kids" rel="nofollow noreferrer">google</a> (which you have probably seen), such as:</p>
<ul>
<li><a href="https://www.kidscodecs.com/what-is-3d-printing/" rel="nofollow noreferrer">kidscodecs - What is 3D printing?</a></li>
<li>All3DP has <a href="https://all3dp.com/1/3d-printed-toys-kids-3d-printing-toys/" rel="nofollow noreferrer">3D Printed Toys – 11 Ideas for Children of all Ages</a>, but these <em>seem</em> to need to be purchased.</li>
</ul></li>

Such an app would probably provide examples for them to get started with. One such app is the <a href="https://toymaker.astroprint.com" rel="nofollow noreferrer">Toy Maker by AstroPrint</a> - although that may require a commercial printer, I'm not sure.

<p>Sometimes, "don't try to do what you're trying to do" is the only valid answer, see e.g. <a href="https://meta.stackexchange.com/questions/66377/what-is-the-xy-problem">XY problem</a>.</p>

<p>Things like Uservoice are great for generic suggestions and even finding bugs but they rarely answer your specific questions/concerns because that's not what they're there to do.</p>
<p>I also don't think they're that good at keeping a community together. Seriously. Pushing your users to another site where they have limited interest isn't in my handbook for cultivating communities. </p>
<p>You want:</p>
<ol>
<li><p>... to keep users on <em>your</em> site. Pop-in JS things are <em>okay</em> if branded well. But they might still have to log in and then there's the problem of...</p></li>
<li><p>... to keep them involved in problems they raise. If somebody raises feedback, raise some back at them. Trap them in the process. Ask them more questions about what they feel is right or why they feel something was wrong in the first place.</p></li>
<li><p>... to make giving feedback desirable. One of the reasons SO works so well is its points system. Points mean prizes (or status and power, here) and that's a great way to make people want to keep going at it. Some users will just care and incentives just sweeten the deal but most users won't really care enough without the prospect of benefiting from it some how.</p></li>
</ol>
<p>Just to skip back to the point that external services are too generic for directed feedback. As a developer, you sometimes need to ask specific questions to know when something needs changing and this feedback usually needs to be asked at very specific points, usually after a task.</p>
<p>Stick feedback questions <em>on your site</em> at the end of tasks. Eg if a user posts a new something-or-other, at the end of the process, stick an unmissable box in there, asking them how it was for them. You can ask relevant questions and you'll catch more problems because people have just done the task (opposed to them noticing your feedback tab 10 minutes later when they've forgotten half of it).</p>

<p>Welcome to the fantastic, sometimes frustrating but most often glorious world of 3D printing David! :)</p>
<p>Your question is really very very broad, but here's my contribution to make your first steps a success. First of all: I don't have experience with the Robo R2, but judging from the specs available online, I would say that you got a machine that take care of most of the troubles beginners encounter when starting out (e.g.: levelling the bed) and has a few features that allow you to print more reliably/with better quality (heated bed, enclosure, possibility for a second extruder).</p>
<p>Give a hug to whoever made the gift to you! ;)</p>
<p>I like to think to 3D printing as a process that involves 4 phases (well, normally several iteration of them as <em>prototyping</em> is a thing):</p>
<ul>
<li>Designing (creating the mesh, i.e. the shape of the object you want to print)</li>
<li>Slicing (creating GCODE, i.e. the file with the step-by-step instructions for moving your printer nozzle in space, extruding the plastic, controlling temperatures and cooling, etc...)</li>
<li>Printing (the actual process of having your printer running that GCODE)</li>
<li>Post-processing (finishing the piece, by for example removing support material, sanding, vapor-smoothing the surface, painting, etc...)</li>
</ul>
<p>Technology in the 3D printing world is moving so fast that printed information tends to get outdated quickly, and the Internet is often the best source of information. So in the following bits I will mention the the source of information that I use[d] for myself, of which many are online rather than in print.</p>
<p><strong>DESIGN</strong></p>
<p>Broadly speaking, there are two kind of designs one can do: <strong>decorative</strong> or <strong>functional</strong>. Decorative designs are those in which the final object will essentially sit still on a shelf or be handled very gently (e.g.: a model of the Tour Eiffel, a miniature for RPG gaming), functional designs are those in which the final part will have to bear a load or perform some sort of mechanical work (e.g.: a drone, a shelf bracket, a pipe adapter...).</p>
<p>Both designs need to take into consideration the physical limitations of FDM printers such as the fact that the nozzle is round and with a fixed diameter, or the fact that molten plastic needs to rest onto something, thus the need for support.</p>
<p>Additionally, functional design requires an understanding of the physical properties of 3D MFD printed parts (hint: they are anisotropic, so their properties differs along their axis). If you are interested in functional designing a book that I can highly recommend is <a href="https://www.amazon.co.uk/Functional-Design-3D-Printing-Designing/dp/0692883215/" rel="noreferrer">Functional Design for 3D Printing by Cliff Smyth</a>. It is concise, accessible and full of information you'll be using from your very first design.</p>
<p>In terms of tools, for decorative, organic forms, you will probably want to use a program like <a href="https://www.blender.org/" rel="noreferrer">Blender</a>, that manipulate meshes directly, while for functional designs will probably turn to CAD software, like for examaple <a href="https://www.freecadweb.org/" rel="noreferrer">FreeCAD</a> that operate on a "model" and let you export the finished part as a mesh at the very end.</p>
<p>Both Blender and FreeCAD are free software (like in: "free speech") but commercial versions do exist as well (most notably from Autodesk).</p>
<p>Blender is professional grade software with a very steep learning curve and I would suggest to take an structured online course like <a href="https://www.udemy.com/blendertutorial/learn/v4/overview" rel="noreferrer">this one</a> about it, rather than trying to learn it the DIY way.</p>
<p>FreeCAD belongs to a category of CAD programmes that operate on a well defined, well understood, set of principles (so it works similarly to OnShape and Fusion360 for example) and it is much easier to learn. In my experience CAD modelling is best learnt by understanding the very basic, and then just researching further information as you go, according to the needs of your project as CAD design is full of small specific operations that is useful to know only if you actually need them (e.g.: how to draw a screw thread, or to perform a loft). I started out with <a href="https://www.youtube.com/watch?v=_HEvhclR4-o&list=PL6fZ68Cq3L8k0JhxnIVjZQN26cn9idJrj" rel="noreferrer">this series of video tutorials</a> by the late Roland Frank (a celebrated contributor to the FreeCAD community), but there are tons of other tutorial should you choose to go with a commercial product.</p>
<p><strong>SLICING</strong></p>
<p>Slicing is as much an art as it is science. While the actual work of generating the GCODE is automated and requires just the click of a button, there are a myriad of settings that are mutually interdependent in their effect. For example: filament temperature, movement speed, cooling fan, retraction and coasting all affect oozing, but each of them also affect other things (bridging, layer adhesion, curling, nominal overextrusion, etc...).</p>
<p>Also: settings differs for each filament material, each brand, and sometimes even different spools from the same material/brand. Moreover, you may wish to tune them depending to what you are printing (maybe you are printing a finely detailed miniature and want to go slower to reduce vibration, or maybe you are printing a torsion bar and want to increase the temperature for increasing layer adhesion, for example...).</p>
<p>IMO the best way to understand how settings affect your print is playing around with calibration towers (<a href="https://www.thingiverse.com/thing:1956512" rel="noreferrer">example</a>) and torture tests (<a href="https://www.thingiverse.com/thing:1363023" rel="noreferrer">example</a>).</p>
<p>Calibration towers work by printing the same thing on top of each other but changing at each repetition a specific setting (like filament temperature, or extrusion multiplier). You will then visually inspect the final piece and evaluate how the print quality changed relative to that parameter.</p>
<p>Torture tests work by putting in the same piece a number of features that are hard for the printer to print correctly (thin walls, bridges, overhangs, to name a few).</p>
<p>A specific model that is sort of gold standard as a basic test is the <a href="http://www.3dbenchy.com/" rel="noreferrer">3D benchy</a>. The good thing about it is that it comes with a full website that also tell you how you can evaluate the print. However, the benchy - differently than torture tests - is not designed to let you discover the limits of your printer, it is more of a quality-control test. If you can print a 3D benchy, you should be good to go for printing "regular" objects.</p>
<p>Also, at least in the two most common free-as-in-freedom slicers (<a href="https://ultimaker.com/en/products/ultimaker-cura-software" rel="noreferrer">Cura</a> and <a href="https://github.com/prusa3d/Slic3r/releases" rel="noreferrer">slic3r Prusa Edition</a>) each setting comes with some explanatory text while hovering on it, that helps a lot understanding what that setting does).</p>
<p><strong>PRINTING</strong></p>
<p>How much you can affect the actual printing process depends from how "open source" is your printer, and if it uses standard components or not. Consumer-grade printers get often upgraded/modded to improve print quality or tweak them for a specific job/material. Typical upgrades are extruder upgrades, stepper motor upgrades, vibration dampeners, different sensors, etc...</p>
<p>Each printer is unique, but normally you can find abundant information wherever the community of owners of a specific model gathers.</p>
<p>I would also advise to subscribe to some good youtube channel about 3D printing like <a href="https://www.youtube.com/user/ThomasSanladerer" rel="noreferrer">Tom's</a> or <a href="https://www.youtube.com/user/TheMakersMuse" rel="noreferrer">Makers Muse</a> or <a href="https://www.youtube.com/channel/UC_7aK9PpYTqt08ERh1MewlQ" rel="noreferrer">Joel's</a>, and to visit sites like <a href="https://all3dp.com/" rel="noreferrer">All3dp</a> regularly. As I mentioned, 3D printing tech changes constantly, and it is good to keep tabs on new materials, new software, new components, etc...</p>
<p><strong>POST-PROCESSING</strong></p>
<p>This is entirely dependent from the material you used for the print, its size, and its intended use, but I wanted to mention this nonetheless as there are amazing things you can do with <a href="https://www.youtube.com/watch?v=Xj53P2YzYGM" rel="noreferrer">acetone on ABS</a>, lot of <a href="https://www.youtube.com/watch?v=0vgynnYzo08" rel="noreferrer">elbow grease on PLA</a> or the <a href="https://www.youtube.com/watch?v=oj1kgFHo3sU" rel="noreferrer">use of an airbrush</a>... so you know 3D printing does not end with the print! ;)</p>
<p>Hope this helps you at least a bit. Again: welcome to the the 3D printing world! :)</p>

<p><a href="https://electronics.stackexchange.com/questions/244366/how-do-i-tell-if-my-thermistors-are-10k-or-100k">This question</a> was migrated to electronics.SE. To me the migration makes no sense:</p>
<ul>
<li><p>The question deals with a problem that is relevant to the users of this site</p></li>
<li><p>This site can provide a more specialized answer than electronics.SE can provide: you don't just need to know whether it's a 10k or 100k thermistor, but also figure out the correct thermistor table in your firmware. electronics.SE does not have knowledge of 3D printer firmware, which is the issue underlying this question.</p></li>
</ul>
<p>Obviously there's some overlap between Arduino/Electronics/3D printing, but what determines whether a question should be migrated?</p>
|
<p>The question was migrated because the specific question of "<em>How do I tell if my Thermistors are 10k or 100k?</em>" is going to be best answered by users of Electrical Engineering SE. This also provides the SE network with more appropriate traffic based on the question at hand.</p>
<p>However, if the question of "<em>How can I change the thermistors settings in Marlin firmware?</em>" were to arise, then the question would be best suited here on 3D Printing. It might help both SE sites by providing links to each other's relevant questions for future users to reference.</p>
<p>If the question was something like "<em>How can I wire a hotend?</em>", this would be more appropriate here on 3D Printing SE as users in Electrical Engineering SE may not know as much about the topic compared to users in 3D Printing. This may be a poor example, but the idea is that there is strict correlation between <em>hotends</em> and 3D printing, whereas identifying thermistors is not a specific topic to just 3D printing.</p>
<p><strong>Update</strong></p>
<p>After reading a few posts on SE meta, <a href="https://meta.stackexchange.com/questions/10249/what-is-migration-and-how-does-it-work">this one</a> leads me to agree with you that this particular question may not have needed to be migrated. However, it exposes an important question of how we want to proceed with questions like this in the future? How far down the rabbit hole do we want to allow this site to go in this topic? I'd recommend others pitch in recommendations in answers here on what would be the appropriate topic in this case that can be applied to our <a href="https://3dprinting.stackexchange.com/help/on-topic">On-Topic</a> page so that it may be amended.</p>

<p>I completely agree! I just posted <a href="https://3dprinting.meta.stackexchange.com/questions/197/3d-printing-se-beta-status">my own reminder</a>, focusing more on efforts to get us out of Beta.</p>

<p>It should not be about merging of tags, rather we should come up with a proper terminology to identify the correct parts of the "build platform".</p>
<p>Basically, every printer consists of a frame with some sort of guide rails<sup>1</sup> moving a carriage. On this carriage a build surface is attached where the printer prints the print on; it is always the top of the stack. Note that this can be e.g. a moving Y-axis<sup>2</sup> or moving Z-axis carriage<sup>3</sup>. In some cases the carriage is missing and there is just a static mounting, then it's a platform instead<sup>4</sup>. It is basically irrelevant if the build surface is glued to the stack or removeable in some way or another.</p>
<p>Between the carriage and the build surface you can have have a stack of multiple elements: a structure or structures, a plate, plates or matts, insulation, etc. This <strong>whole</strong> assembly of elements make up the build platform, an example is shown below.</p>
<p><a href="https://i.stack.imgur.com/M3xCs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/M3xCs.png" alt="Proposed build platform terminology" /></a></p>
<p>Note that the linear support can be mounted in Y or Z direction. To tag the elements that make up the <em>build platform assembly</em>, a proposed solution can consist of the following terms for subassemblies:</p>
<ul>
<li><a href="https://3dprinting.stackexchange.com/questions/tagged/z-axis" class="post-tag" title="show questions tagged 'z-axis'" rel="tag">z-axis</a> or <a href="https://3dprinting.stackexchange.com/questions/tagged/y-axis" class="post-tag" title="show questions tagged 'y-axis'" rel="tag">y-axis</a> in combination with <a href="https://3dprinting.stackexchange.com/questions/tagged/carriage" class="post-tag" title="show questions tagged 'carriage'" rel="tag">carriage</a>,</li>

<p>Well done for bringing this up. I was looking at those numbers too. </p>
<p>Referring to <a href="https://3dprinting.meta.stackexchange.com/questions/264/what-does-it-take-to-get-out-of-beta-stage/265#265">this post</a>, almost all of the stats are improving (albeit) slowly, except for one, the ApQ </p>
<blockquote>
<p>Are users put off by an expectation that a wrong answer might lose them rep?</p>
</blockquote>
<p>It seems that way. Without wishing to provide a link to the actual comment, I noticed a comment the other day that suggested as much, and a nicely detailed comment was left instead. </p>
<p>To be fair, I feel that way sometimes, and often hesitate (maybe rightly so to save myself from spamming the site) in posting questions on SE.Meta, as there are a number of drive-by downvoters there<sup>1</sup>. Unless you have a definite bug that you are able to document clearly or have a well rounded proposal that can be implemented easily, then your question may end up downvoted. This is probably rightly so, TBH, in most cases, but nevertheless it can be discouraging.</p>
<p>If you don't have much hard-earned rep then you may be less willing to risk it by posting a informative answer, that only answers half the question. Is that a bad thing? Well, it is a double edged sword. It is a good thing, because that promotes good solid answers, but with the downside that you point out (a lack of multiple answers per question).</p>
<p>What can we do? Probably, not much other than creating a small community by promoting a friendly environment and communicating more clearly... Inviting people to chat in the chatroom, being more welcoming (with Hi and welcome), actually helping people without the old "Did you google this?" immediately. All of these things help a lot. And which we seem to have developed of late. So we seem to be getting there.</p>
<p>I know that a number of members have already been adding answers to single answer questions as well as tackling the unanswered queue too. The more people that help the better...</p>

<p><sup>1</sup> Don't get me wrong, I looove (justified) downvotes, but I would like to know <em>why</em>.</p>

<p>If someone has a question from one of those older sites, they should go ahead and ask it. But a wholesale importing of content from elsewhere is not really a desirable way to build this site. </p>
<p>There is a lot of ownership and careful curation that goes with vetting the content of this site. Questions imported from elsewhere would always have that air of odd, forgotten legacy content back-dated and <em>anonymous</em> with no owners or real-time vetting at all. If someone posts another answer or asks for some followup to one of these questions, no one will receive the notification. Essentially, we would be loading this site up with a lot of questions asked and answered a long time ago without imparting any of the benefits of reputation, ownership, or experience into the community that is supposed to take care of it.</p>
<p>That's why we don't do it.</p>

<p>I noticed that the most popular tag (82 questions tagged) is <a href="https://3dprinting.stackexchange.com/questions/tagged/3d-printer">3d-printer</a>, and that we also have a <a href="https://3dprinting.stackexchange.com/questions/tagged/3d-printing">3d-printing</a> tag (23 questions). These seem extremely redundant to me, given that they <em>should</em> apply to any question that is on-topic and thus serve no practical purpose. These tags are simply too broad.</p>
<p>The usage guidance for 3d-printer is quite board ("Questions about a specific brand, model, or type of 3D printer.") and 3d-printing does not even have one.</p>
<p>I would suggest to get rid of these tags. For comparison, <a href="https://stackoverflow.com/tags">Stack Exchange</a> does not have a programming tag either. However, they do have various tags that end in "-programming", such as "functional-programming", "linear-programming", etc... Our equivalents would be fdm(-printing), sla(-printing),...</p>

<p>These are <strong>NOT</strong> the same in a manufacturing, which 3D printing is primarily considered a part of.</p>
<p>Post-Processing typically refers to additional steps that must/can be done to produce the nominally desired part. These steps can include deburr, grind, and other additive/subtractive processing on the physical part.</p>
<p>Post-Production typically refers to any steps that typically do not "produce" or alter the dimensions of the product. These steps can include final visual and dimensional inspection, packaging, and sometimes even shipment.</p>
<p>I would not recommend creating a synonym, but merely updating the definition of both terms.</p>

<p>While I might not have the wildest credentials or reputation, I have been around the StackExchange network for a while (11/2012) and generally know my way around the sites.</p>
<p>Mostly active on StackOverflow, I answer when I can, and try and do my part to clean up the review queue: ~5000 review tasks; I plan on giving this site as much attention as I can.</p>
<p>I started <a href="https://area51.stackexchange.com/proposals/82438/3d-printing">this 3D Printing proposal</a> just under a year ago on Area 51, and am either way, glad to see the day we made it to beta.</p>

<p>All printers are designed with an idea of <a href="https://en.wikipedia.org/wiki/WYSIWYG" rel="nofollow">WYSIWYG</a> for sure. Depending on:</p>
<ul>
<li>printer - type/quality/settings/configuration/assembly precission</li>
<li>filament - type/quality/shrinkage</li>
<li>user skills - manual/using app proficiency</li>
<li>model complexity</li>
<li>environment conditions and so on</li>
</ul>
<p>you can get different results.</p>
<p>I venture to say users know their printers (after some time and by trials and errors) so they know how to manage dimensions to compensate all above so you will get this knowledge too.</p>
<p>Mathematical formula can describe shrinkage of the material, all other elements are very hard to describe (mathematically) in a general way.</p>
<p>Of course someone can simplify it and say: more money you spend better effects you'll get. It's sometimes true ;)</p>
<p>So all your modular things will be better and better if you will increase (what is to be increased) in above points especially "user skills".</p>
<p>Is engineering paramount? It depends of whay you gonna create. If your modular things have to lock itself, have to have threads, screws and such stuff then this is engineering. Is it the most important part of the design? Not necessarily.</p>
<p>I would say 3D printing moved engineering to next level. I'm talking about <a href="http://www.thingiverse.com/thing:258201" rel="nofollow">this</a> or <a href="http://www.thingiverse.com/thing:249341" rel="nofollow">this</a>. Is it still art or engineering? :)</p>
<p>This is my receipt:</p>
<p><em>think > imagine > design > rethink > redesign > give it a try > get back to thinking</em></p>
<p>good luck</p>

<p>My guess is that it is a correlation between which tags are most often used together.</p>
<p>For example:</p>
<ul>
<li>Question A tagged with tag1, tag2</li>
<li>Question B tagged with tag1, tag3</li>
<li>Question C tagged with tag1, tag2</li>
</ul>
<p>Then it's natural to assume that tag2 "is related to" tag1.</p>
<p>I would say the best place to learn would be <a href="http://my.safaribooksonline.com/9780596529321" rel="noreferrer">O'Reilly's Programming Collective Intelligence book</a>.</p>

<p>In past few months, there are a devastatingly few number of users that cast up votes, and many of users aren't coming back to site, and existing users don't have so much reputation, because no one is voting up great questions / answers.</p>
<p>So... let me start like this..</p>
<p><a href="https://3dprinting.stackexchange.com/users?tab=Voters&filter=all">THIS IS REALLY DEVASTATING</a></p>
<p>We all need to vote up users and try to answer their questions, so we can get more users answering / asking questions. Main reason I'm writing this post is because this is great site, but we need new regular users that are going to vote and ask questions. I think it all came down to 20-30 active users, and rest of users aren't so active.</p>
<p>I'm relatively new to site. I've decided to use it because it helped me a lot, and I'm doing my best to answer the questions. My main concern is also that my answers also don't get any vote up.</p>
<p>So... I'll let it all out. I think that main concern that we need to focus on is motivation.</p>
<p>WE NEED TO MOTIVATE OTHERS TO VOTE. And we all can do that if we vote other users up.</p>
<p>That's from my perspective. Even one vote up motivates you to go further.</p>
<p>I think that I explained what I mean. :) It's all in VOTE UP!</p>
|
<p>I completely agree! I just posted <a href="https://3dprinting.meta.stackexchange.com/questions/197/3d-printing-se-beta-status">my own reminder</a>, focusing more on efforts to get us out of Beta.</p>
<p>I'm sorry you can feel discouraged sometimes, I think a lot of users around the Stack Exchange network can feel that way at times.</p>
<p>I think people sometimes forget that an up-vote to an answer isn't necessarily that it was helpful to you, specifically. But, rather that <strong>the answer is a good <em>quality</em> answer</strong> and <strong>will be <em>useful</em> to others</strong> as well!</p>

<p>For common problems that get asked a lot, I wouldn't just close these as <em>too broad.</em> A better solution is to create a <strong>canonical post</strong> like this:</p>
<p><a href="https://superuser.com/a/260078/697"><strong>How do I troubleshoot when I have no clue where to start?</strong></a></p>
<p>These attract a <em>lot</em> of users. </p>
<p>The goal is to create a step-by-step trouble-shooting guide to explain what lights, nozzles, and sneedles to look when you're kwigger isn't going <em>zong.</em></p>
<p>And don't just answer with a hyperlink to some other discussion group somewhere. Do everything you can to really overkill it. Write a detailed, step-by-step, ultra-clear guide, so when zillions of people with this problem go searching, you stand a good chance of the best possible answer on the web. </p>
<p>This is one of those opportunities to attract some great new users who will add value for years to come.</p>

<p>On a heavy-traffic site like Stack Overflow, I would only update the "last seen" variable when a user actually <em>does</em> something. Lurking around and reading questions and answers shouldn't count as a user being "seen" by the system. Asking and answering questions, or voting on them should be actions that update when a user is last seen.</p>
<p>I won't talk about the implementation details because that's already covered by other answers (and I would probably get it wrong).</p>
|
<p>That sounds suspiciously like my Stack Overflow reputation score.</p>

<p>The tags <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> & <a href="https://3dprinting.stackexchange.com/questions/tagged/support-structures" class="post-tag" title="show questions tagged 'support-structures'" rel="tag">support-structures</a> are in fact referring to exactly the same thing!</p>
<p>Furthermore, the meaning of support can be interpreted differently (i.e. helping out).</p>
<p>I support renaming/merging the <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> labelled questions to <a href="https://3dprinting.stackexchange.com/questions/tagged/support-structures" class="post-tag" title="show questions tagged 'support-structures'" rel="tag">support-structures</a>. This implies that the <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> tag is removed and it could be reinstated at any time by new questions. Users with enough reputation can remove the <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> tag if it gets recreated and we could create a synonym later. </p>
<p>In my humble opinion, the best solution may be to rename <a href="https://3dprinting.stackexchange.com/questions/tagged/support" class="post-tag" title="show questions tagged 'support'" rel="tag">support</a> to <a href="https://3dprinting.stackexchange.com/questions/tagged/supports" class="post-tag" title="show questions tagged 'supports'" rel="tag">supports</a> and then make it a synonym for <a href="https://3dprinting.stackexchange.com/questions/tagged/support-structures" class="post-tag" title="show questions tagged 'support-structures'" rel="tag">support-structures</a>!</p>

<p>There is a whole lot in the literature on voting systems, and a good bit of game theory can be applied. The issue that's difficult is that it's inherently probabilistic; you pick certain patterns as indicating <em>probable</em> fraud, and detect or exclude them; by doing so, you also exclude the possibility that someone is voting that way for innocent, or at least non-fraudulent reasons.</p>
<p>Consider, eg, someone who reads my deathless prose, develops an instant man-crush on me, and goes through all my answers voting each one up. I've got more than 30 answers so it would take a few days. Now, by assumption, this isn't my reputation-whoring sock-puppet, it's a person who for their own reasons, however unwise, has devoting all their voting to me for days at a time.</p>
<p>Is this fraud? No, but it would be detected as, and probably treated as, fraud.</p>

<p>This question may require migration to Meta.SE, as it could be a site-wide "bug", but I thought that I would test the waters here, to see if there is an obvious explanation.</p>
<p>I noticed that a question of mine had been modified, on April 16, by "Song Khmer" <strike>in the <a href="https://3dprinting.stackexchange.com/unanswered">unanswered questions list</a>, when sorted by votes</strike><sup>1</sup>:</p>
<blockquote>
<p><a href="https://i.stack.imgur.com/nY7mi.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nY7mi.png" alt="Modification listed"></a></p>
</blockquote>
<p>However, when checking the <a href="https://3dprinting.stackexchange.com/posts/3015/revisions">revision history</a>, the April 16 edit, by <em>Song Khmer</em>, is not shown. The last modification was the "https everywhere" edit, three days prior:</p>
<blockquote>
<p><a href="https://i.stack.imgur.com/p5B9M.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/p5B9M.png" alt="No apparent modification"></a></p>
</blockquote>
<p>I've not noticed the behaviour before. What is going on? Is it a bug, or something really obvious that I can't see? </p>
<p>Was it a rejected edit? If the latter, then should it really be shown in the Unanswered question list? Shouldn't the modifications listed in the Unanswered questions list, actually only be accepted modifications/edits?</p>
<hr>
<p><sup>1</sup> The unanswered list, and the sorting, are irrelevant to the actual issue.</p>
|
<p>Regarding the "invisible modification", there is technically a modification made multiple times by the user <strong>Song Khmer</strong> (now destroyed). This user was posting nonsense to your question by copying text from your question and posting it as an answer.</p>
<p>The reason you probably did not see this in the revision history is:</p>
<p>1) it wasn't a direct edit to your question</p>
<p>2) I believe only moderators can see deleted posts.</p>
<p><a href="https://i.stack.imgur.com/2VAiLs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2VAiLs.png" alt="enter image description here"></a> <a href="https://i.stack.imgur.com/2VAiL.png" rel="nofollow noreferrer">click here for full view</a> of deleted posts</p>
<p>I'm pretty sure that anytime someone posts an answer or edits your question, the post raises the modified flag. In this case, when the user was posting answers it would properly flag the post. But, the flag remained even after the answers were deleted (there were 3 answers).</p>

<p>Another wild guess: SelectionChanged</p>
|
<p>This only happens with conflicts - basically svn tried to merge the change in, but (roughly speaking) saw the change as:</p>
<p>Add</p>
<pre><code>2008-08-06 Mike Stone <myemail>
* changed_file: Details.
</code></pre>
<p>before</p>
<pre><code>2008-08-06 Someone Else <their_email>
</code></pre>
<p>And it couldn't find the Someone Else line while doing the merge, so chucked that bit in for context when putting in the conflict. If it was a non-conflicting merge only the changes you expected would have been applied.</p>

<p><a href="http://twiki.org" rel="nofollow noreferrer">TWiki</a> automatically merges <a href="http://twiki.org/cgi-bin/view/TWiki.SimultaneousEdits" rel="nofollow noreferrer">Simultaneous Edits</a>.</p>
<blockquote>
<p>TWiki allows multiple simultaneous edits of the same topic, and then merges the different changes automatically. You probably won't even notice this happening unless there is a conflict that cannot be merged automatically. In this case, you may see TWiki inserting "change marks" into the text to highlight conflicts between your edits and another person's. These change marks are only used if you edit the same part of a topic as someone else, and they indicate what the text used to look like, what the other person's edits were, and what your edits were.</p>
<p>TWiki will warn if you attempt to edit a topic that someone else is editing. It will also warn if a merge was required during a save. </p>
</blockquote>
<p>There was also some <a href="http://twiki.org/cgi-bin/view/Codev/DakarMergeModel" rel="nofollow noreferrer">documentation</a> from that feature being developed detailing how it would behave.</p>
<blockquote>
<p>The basic principles I used in coding up the mergeing algorithm were:</p>
<ol>
<li>If it's possible to merge without using conflict markers, do so.</li>
<li>If it's possible to merge using conflict markers, do so.</li>
<li>If it's not possible to merge, then the most recent checkin wins. </li>
</ol>
</blockquote>
<p>It's worth noting that TWiki has a similar feature to Stack Overflow for collapsing subsequent revisions by the same user within a certain time limit and this <a href="http://develop.twiki.org/~twiki4/cgi-bin/view/Bugs/Item1897" rel="nofollow noreferrer">caused a bug when happening in conjunction with a merge</a>.</p>
<blockquote>
<ol>
<li>User A edits topic</li>
<li>User A saves rev N</li>
<li>User B edits topic, picks up rev N</li>
<li>User A edits topic again, picks up rev N</li>
<li>User A saves changes; save sees that the change is within the ReplceIfEditiedWithin? window, <strong>so does not increment the rev number</strong></li>
<li>User B saves, code sees that <strong>the rev number on disc has not changed since they started editing</strong> so doesn't detect a need to merge. </li>
</ol>
</blockquote>
<p>Also worth noting is that TWiki will warn the second user that the topic is being edited:</p>
<blockquote>
<p>So I invented the concept of "leases". When a topic is edited, a lease is taken on the topic for a fixed period of time (default 1h). If someone else tries to edit, they are told that there is already a lease on the topic, but that doesn't stop them from editing. It isn't a lock, it's just a way of advising them. Mergeing is still the prime resolution mechanism; the lease is purely advisory. If a user - or a plugin - chooses to back away from a topic because someone has a lease out on it, well, that's up to the plugin.</p>
<p>The descriptive comment in TWiki.cfg is as follows:</p>
<pre><code> # When a topic is edited, the user takes a "lease" on that topic.
# If another user tries to also edit the topic while the lease
# is still active, they will get a warning. The warning text will
# be different depending on whether the lease has "expired" or
# not i.e. if it was taken out more than LeaseLength seconds ago.
</code></pre>
</blockquote>
<p>note that the lease terminology is only for developers, not end users.</p>

<p>Actually the problem was probably Firefox. When I clicked on <em>Answer you own question</em> here on Stackoverflow, I had the very same problem: My request, wasn't processed properly. I was sent back to the normal question view, without having the ability to submit my own answer.</p>
<p>So after a restart of Firefox everything worked fine.</p>
<p>(I also reinstalled Ruby and Rails at the same time, so I can't be sure, if it was Firefox for sure).</p>
|
<p>I think that using before_filter on the edit action is the least obtrusive. </p>
<p>The referer should be reliable enough ... simply have a default in the case of no referer being available (say: someone bookmarked the edit page) and you should be fine. </p>
