SAE International has announced the release of its first suite of Aerospace Material Specifications (AMS) additive manufacturing materials and process specifications which will 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
“Given that advanced materials and advanced manufacturing are strategic focus areas for SAE International, we are committed to supporting the aerospace industry’s adoption of additive manufacturing technologies,” said David Alexander, Director of Aerospace Standards at SAE International. “Tremendous effort was expended by industry and regulatory stakeholders from North America, Europe and beyond to develop this initial suite of material and process specifications which help address the regulatory authorities’ request for guidance material for this emerging technology.”
“SAE looks forward to assisting with the migration from point design to material qualification by continuing to develop additive manufacturing aerospace material and process documents containing statistically validated specification minimum values,” he added.
Supported by a Federal Aviation Administration tasking letter to assist regulatory authorities in developing guidance materials for additive manufacturing (AM) certification and established in 2015, SAE International’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. Over 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.
AM is a process that offers many benefits over conventional manufacturing methods for aircraft components due to its ability to reduce weight and production costs, manufacture at high speeds with great accuracy and decrease constraints of the existing supply chain.
