Multiscale Sintering Simulation of 316L Produced by LMM

This is the authors' abstract. We don't add key points for this paper.

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.
