Additive manufacturing (AM) of metals is attractive due to its customizability, energy efficiency, and lower cost compared with conventional manufacturing methods. AM materials impose a new complexity through the build pattern of the particular additive process used, in addition to the polycrystalline microstructure within that pattern.
Significant microstructural differences may be obtained for changes in the deposition process or the shape of the deposited material. This project is aimed at comparing microstructures of stainless steel built using three different deposition methods starting from the same stock powder material. There are several differing possible parameters used in each build process from each site and build direction. Steel samples deposited using LENS, electron beam powder bed, and laser powder bed are used to evaluate microstructural changes depending on deposition process and direction. Post-mortem metallographic analysis will be used to compare each sample microstructure and unveil connections between differing microstructures.
