Selective Laser Melting (SLM) is a common additive manufacturing process which uses a laser energy source to fuse metal powder layer by layer. Engineering properties and microstructure are related to the part’s thermal history. It is important to measure the thermal history in-situ to qualify parts and provide the sens...

Traditionally it has been difficult to develop and verify designs for 3D reticulate cellular structure. Additive manufacturing provided a feasible alternative for this challenge. In this work, a 3D octahedral cellular structure was designed and investigated. Using a combined method of simulation and experimentation, th...

Microscale Selective Laser Sintering models have been built as a basis to predict the properties of sintered nanoparticles under isothermal heating. These models use Phase Field Modelling (PFM) to track the diffusion of nanoparticles, resulting in properties such as the change in relative density and shrinkage of the s...
