<p>1) Descarded imediatelly! I'll not even justify. :)</p>
<p>2) If you need a simple, quick, one-method persistence, stick with it. It will persist the complete data graph as it is! Beware of how long you'll be maintaning the persisted objects. As yo... | 5,792 |
<p>I'm looking to 3D print a structure that won't deform in high heat, up to about 220 °C. The filament itself can be 3D printed all the way up to about 380 °C. </p>
<p>PEI seems like it could be a viable option. I found some <a href="https://www.matterhackers.com/store/l/3dxtech-thermax-pei-175mm-05... | <p>Your expected operating temperature exceeds the glass transition temperature by 3 °C. This implies that the structure will become weak and can deform under load. </p>
<p>Note that you cannot simply print PEI on a normal machine, it requires a special high temperature capable printer with hot end temperatur... | <p>An easier but less simple solution might be to make a PLA 'pattern' that is the right size and shape, then use that to cast your item in aluminium (melting point ~ 660C) using the 'investment' or 'lost PLA' process.<br>

<p>They both seem to fulfill the same purpose. When would I chose one over the other?</p>
| <p>Use the events when you've got a thread that is waiting on one of or all of a number of events to do something.</p>
