| Abstract Scope |
Metal additive manufacturing offers significant benefits in industries such as medical and aerospace, but its broader adoption and potential supply chain improvement are hindered by limited material options and long lead times for powder feedstock production. In this study, we introduce a novel "on-demand" powder production technology called cold mechanical derived (CMD), capable of producing non-spherical or spherical powders with high efficiency and properties comparable to wrought materials. We used binder jet printing to process this new feedstock and achieved a relative density exceeding 98.5%. Through microstructure analysis, dimensional shrinkage assessment, and potential carbon contamination characterization, we compared the results with spherical powder. A binder printed complex part with intricate geometry was successfully manufactured with a relative density of 97. This research paves the way for expanding the range of alloys and promoting the utilization of non-spherical powders, thus enhancing the available supply of new alloys for additive manufacturing. |
