Additive manufacturing (AM) has allowed for the rapid prototyping of parts and the ability to control the structure of a material and, to a lesser extent, the microstructure. AM as applied to metals, as stainless steel is especially promising as it provides the ability to produce complex shaped components rapidly. Laser-powder bed fusion (L-PBF) is one such technique in which the part is formed from the base up by fusing successive layers of powder. As each layer is fused, the print plate moves down and a new layer of metallic powder is swept over the top. A laser then welds this layer to the top of the existing piece and the process repeats.1 However, AM can result in non-equilibrium microstructures, porosity, and residual stresses that could affect the longevity of the material and performance in corrosive conditions.
