Additive manufacturing, Stainless steel


Metal additive manufacturing provides the ability to print near-net-shape parts through a layer-by-layer process, presenting a new approach to produce complicated assemblies in one manufacturing step. MAM processes are usually characterized by the heat source and feedstock used. Another area of interest is the purge gas that is utilized in these processes. Stainless steel 316L is an austenitic stainless steel derived from 304 stainless steel to include higher strength and better weldability. The objective of this research is to determine the effects of purge gas and cooling rate during heat treatment in the additive manufacturing of stainless steel 316L using laser powder bed fusion.
