This study investigated the mechanical properties of hybrid additively manufactured, both laser powder bed fusion (LPBF) and direct energy deposition (DED), stainless steel 316L. The implementation of additive manufacturing techniques in the production of large-scale aerospace components is challenged by limited build envelope, feature precision and build speed. Hybrid additive is expected to address these limitations to reduce the number of components required or lightweight complex aerospace structures. Here, DED preforms were built on top of the same made via LPBF and electric discharge machined into coupons for mechanical testing. Their microstructures were also characterized, including a determination of the microstructure at the hybrid interface. This hybrid approach expands the understanding of manufacturability of large-scale critical components with stainless steel 316L.
