Abstract

As the metal Additive Manufacturing (AM) industry moves towards industrial production, the need for qualification standards covering all aspects of the technology becomes ever more prevalent. While some standards and specifications for documenting the various aspects of AM processes and materials exist and continue to evolve, most of such standards are in their infancy within standardization development organizations (SDOs), or under consideration/development. While critical property measurements have been documented with various legacy standards for conventional material forms such as cast and/or wrought structural materials, much fewer standards are currently available to systematically evaluate those properties in AM-processed materials. This is due in part to the current lack of AM-specific standards for metal AM materials, although a number of SDOs are working on addressing these needs. This paper summarizes some of the important standardization activities, as well as considerations for using currently available standards for metal AM with a focus on measuring mission critical properties. Technical considerations in support of future standards development as well as a pathway for qualification/certification are discussed.
