In the last ten years metal additive manufacturing (AM) has transitioned from a rapid prototyping tool to a production tool. This exciting evolution is evidenced by production examples including GE’s Leap fuel nozzle, Stryker’s medical implants, and SSL’s satellite flight hardware. However, this success has been mostly limited to large companies that manufacture components in-house. Industry standards are required for the adoption of AM by small and medium-sized manufacturers and to support the growing AM supply chain. Standards are known to provide the common language and expectations that supply chains require, streamline certification by solidifying expectations, and reduce adoption costs by clarifying equipment capabilities, safety requirements, and workforce requirements.
A variety of standards organizations are working on AM standards, but the rapid development and adoption of AM technologies is challenging the traditional model of standards development. ASTM’s F42 committee was the first standard development organization to begin developing standards in 2009. Since then International Organization for Standardization (ISO), Society of Automotive Engineers (SAE), Aerospace Materials Society (AMS), American Society of Mechanical Engineer (ASME), and American Welding Society (AWS) have joined the cause. A variety of critical baseline standards have been published including AM process terminology and powder characterization specifications. However, as outlined in the Additive Manufacturing Standardization Collaborative (AMSC) mission roadmap developed by AmericaMakes and ANSI, there are a large number of critical gaps remaining.
