This report is a summary of the state of the art for additive manufacturing (AM) certification. Because the development of AM certification is ongoing across multiple domains and disciplines, and due to the limits of this report, some areas may not be covered as thoroughly as some readers would like. In addition, given the expansiveness of the AM field, this report does not present the final answer to every AM issue. It can, however, serve as a gateway to facilitate discussions among experts and policy makers to bridge technical gaps and provide a baseline from which future research can begin.
