SAE International issues new technical standards for aerospace Additive Manufacturing
June 13, 2018
SAE International, Warrendale, Pennsylvania, USA, has released its first suite of Aerospace Material Specifications (AMS) for materials and processes used in the metal Additive Manufacturing of aircraft and spacecraft critical parts. The new standards are expected to aid the certification of metal AM parts for aerospace by providing a framework to protect the integrity of material property data and provide traceability within the supply chain.
The four new standards are:
- AMS7000: Laser-Powder Bed Fusion (LPBF) 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
David Alexander, Director, Aerospace Standards, SAE International, explained, “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.”
“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,” he continued.
“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.”
Established in 2015 and supported by a Federal Aviation Administration tasking letter to assist regulatory authorities in developing guidance materials for AM certification, 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 fifteen countries representing aircraft, spacecraft, and engine OEMs, material suppliers, operators, equipment/system suppliers, service providers, regulatory authorities and defence agencies are said to be active on the committee.
