Abstract Scope Metal additive manufacturing permits a smaller processing footprint, less waste, and potentially lower energy consumption than conventional processes. This presentation explores reuse and increased efficiencies for 316L stainless steel feedstock in directed energy deposition (DED) metal additive manufacturing. First, a systematic investigation of process parameters to increase capture efficiency during sample fabrication will be presented. A new dimensionless number has been developed to predict build efficiencies as well as be fitted to solidification behavior. Second, with the manufacture of test coupons, samples were machined, the chips re-processed into viable feedstock, and reprinted. The mechanical properties of the samples generated with the original gas atomized feedstock and the re-processed machining chips were nearly identical. Finally, the comparison of energy differences between a conventionally processed bracket and a DED fabricated bracket were compared. Increased deposition efficiencies are a key variable to reduce power consumption in the DED process.
