| Abstract Scope |
Powder-feed direct energy deposition (PF-DED) is an additive manufacturing (AM) technology that enables the rapid production of large parts. Typical feedstock materials are inert gas atomized (GA) metal powder, but water atomized (WA) powders are potentially a lower-cost alternative. However, WA powders have irregular shapes and high impurity contents. The effects of the difference in composition as well as the irregular shape of the WA 316L powder are investigated through process parameter development of PF-DED using and compared with GA 316L powder. Printed part geometry and microstructure are analyzed to identify process optimizations that are specific to WA powder and progress future use of WA powder for AM. |
