| Abstract Scope |
Studying the melt pool geometry helps in understanding the process space for a successful prints and also helps determine material properties like laser absorptivity. This study examines the melt pool geometries of refractory metals manufactured by powder-feed directed energy deposition and laser powder bed fusion additive manufacturing. Measured cross-sections were compared to predictions from analytical and finite element heat transfer models. Initial microstructure evaluations were also conducted. Initial observations were made of the effects of process parameters on melt pool geometry and printing outcomes for refractory metals. |
