A revised edition of “A Collection of Powder Characterization Standards for Metal Additive Manufacturing” was recently released. The publication contains nine existing MPIF Standard Test Methods that can be applicable for the characterization of powders used in metal additive manufacturing (AM) processes, with an explanation of each standard. These standards, intended to present and clarify PM technology as an aid in conducting business, relate to those activities that concern designers, manufacturers, and users of metal AM parts.
