Binder jet printing of tungsten heavy alloy

Tungsten heavy alloy powder was processed to make it flowable and of a suitable high apparent density for additive manufacturing (AM). The powder was successfully binder jet printed and sintered to high density. Material in the as-sintered condition was tested and passed all requirements of the ASTM B777 specification for tungsten heavy alloy. Specimens were binder jet printed and an initial assessment of the dimensional capabilities of the process was performed.
