ASTM WK40606

    Work Item: ASTM WK40606 - New Guide for Characterizing Properties of Metal Powders Used for Additive Manufacturing

    (What is a Work Item?)

    Developed by Subcommittee: F42.05 | Committee F42 | Contact Staff Manager



    1. Scope

    This standard guide covers the metal powder that is used for powder-based additive manufacturing processes including binder jetting, directed energy deposition, and powder bed fusion. Determining the properties of the powder used in these processes is a necessary condition for developing industrys confidence in powder selection and ability to produce consistent parts with known and predictable properties. The intention for this standard guide is to provide purchasers, vendors, or producers of metal powder to be used in additive manufacturing processes with a reference for existing standards or variations of existing standards that may be used to characterize properties of metal powders used for additive manufacturing processes. It will serve as a starting point for the future development of a suite of specific standard test methods that will address each individual property or property type that is important to the performance of metal-based additive manufacturing systems and the parts produced by them. While the focus of this standard is on metal powder, some of the referenced methods may also be appropriate for non-metal powders.

    The intention for this standard guide is to provide purchasers, vendors, or producers of metal powder to be used in additive manufacturing processes with a reference for existing standards or variations of existing standards that may be used to characterize properties of metal powders used for additive manufacturing processes.
