Metal powder is a very important element of the metal additive manufacturing (AM). Critical factors influencing powder attributes must be managed carefully through its entire life cycle to produce quality parts at a competitive cost. The life cycle of metal powder includes powder production, shipment, and various additive part manufacturing steps. Powder quality and consistency needs to be maintained at each step of the process, including powder storage and handling.  This requires risk assessment and an abatement plan, along with detailed work instructions/specifications and inspection details. Important elements of metal powder include development of required physio-chemical properties, wide supply base, consistent/cleaner powder, and competitive cost.
