Multiscale Sintering Simulation of 316L Produced by LMM

Additive manufacturing (AM) of metal components has developed rapidly throughout the last decade. Sinter-based processes hereby offer the implementation of AM within existing powder metallurgical process routes, utilizing similar powders and sintering furnaces. While processes such as binder-jetting or fused-filament-fabrication have disadvantages such as limited resolution accuracy, lithography-based metal manufacturing (LMM) enables the production of filigree, complex structures with low surface roughness. However, layer-by-layer powder deposition induces anisotropic shrinkage during the subsequent sintering process.
