SAE Intl. issues four aerospace additive manufacturing technical standards

SAE Intl., Warrendale, Pa., has released Aerospace Material Specifications (AMS) additive manufacturing (AM) materials and process specifications to support the certification of aircraft and spacecraft critical parts by providing a framework to protect the integrity of material property data and provide traceability within the aerospace supply chain.

The four new standards are:

• AMS7000: Laser-Powder Bed Fusion (L-PBF) Produced Parts, Nickel Alloy, Corrosion and Heat-Resistant, 62Ni - 21.5Cr - 9.0Mo - 3.65Nb Stress Relieved, Hot Isostatic Pressed and Solution Annealed
• AMS7001: Nickel Alloy, Corrosion and Heat-Resistant, Powder for Additive Manufacturing, 62Ni - 21.5Cr - 9.0Mo - 3.65Nb
• AMS7002: Process Requirements for Production of Metal Powder Feedstock for Use in Additive Manufacturing of Aerospace Parts
• AMS7003: Laser Powder Bed Fusion Process

Supported by a Federal Aviation Administration tasking letter to assist regulatory authorities in developing guidance materials for AM certification and established in 2015, SAE Intl.’s AMS-AM, Additive Manufacturing Committee, will continue to develop AMS specifications for metal and polymer AM to support the needs of the aerospace industry. More than 350 global participants from more than 15 countries representing aircraft, spacecraft, and engine OEMs; material suppliers; operators; equipment/system suppliers; service providers; regulatory authorities;, and defense agencies are active in the committee.
