This standard is needed to help PBF users understand how to perform practices to predict how a powder would spread in powder bed fusion (PBF) processes. The standard should also provide guidance on how to characterise spreadability. The standard will be used by users of PBF machines to allow them to perform QA checks on powders, prior to using them in PBF machines. These practices would also allow powder producers to develop powder specifications more suited to processing in PBF machines, and allow PBF users to optimise PBF machine parameters for a particular powder feedstock.
The title and scope are in draft form and are under development within this ASTM Committee.
