Abstract Scope |
Best practices for using metal powder feedstocks in additive manufacturing have relied upon establishing conformance to powder specifications. Similarly, industry process specifications have been established to help control for reproducible production of new metal powder feedstocks, but not until recently has a similar document been released to control the processes to prepare recovered used powder for reuse. However, the size scale at which powder requirements are measured and evaluated cannot distinguish between potentially non-conforming, deleterious particles that persist since the first build cycle a powder lot. Therefore, a stopgap powder history scoring metric and labeling schema is currently proposed to both track and associate powder history with user-supplied performance data, guiding the creation of application-specific powder end-of-life determination. An organization may institute a risk assessment posture that relies on this correlated material property data with powder history scoring criteria to identify feedstocks robust to produce parts that meet requirements. |
