AIR7359 explains why AMS-AM metal powder feedstock specifications leave certain properties uncontrolled, citing limited applicability and immature standardized inspection methods, and what that gap means for aerospace AM qualification programs.
As aerospace metal additive manufacturing capacity expands, more reused powder is going back into qualified builds. The virgin-to-reused blend ratio decision depends on PSD shift, satellite formation, and morphology drift, and cannot be settled by a single powder check disconnected from the part's stress state.
