Metallic additively manufactured products can now be found all around us, from bicycle frames and golf clubs to component parts for clocks and vehicles. These products all maintain a high quality of finish and function. You may wonder, what is the crucial factor that allows this quality to be consistently achieved? It all starts from the base material; the metal powder itself.
High integrity powder metallurgy (P/M, the processes for manufacturing metallic components from metal powders) for applications such as additive manufacturing often has strict specification requirements.1 One such requirement is the particle size distribution of the metal powders in question which can affect several of the inherent properties of the powder including; bulk density, ﬂowability, moldability, compressibility, and die-ﬁlling characteristics.
