SAE International released the first Additive Manufacturing (AM) Polymer specifications for the aerospace industry. AMS7100: Fuse Filament Fabrication Process and AMS7101: Material for Fused Filament Fabrication represent the first specifications released under the AMS-AM Additive Manufacturing Non-Metallic (AMS-AM-P) committee. These standards were created following a request from airlines through the International Air Transport Association (IATA)’s EMG to be able to realize additively manufactured plastic cabin parts.

“Both additive manufacturing users and producers will benefit from implementing AMS-AM standards,” said, Paul Jonas, director - technology development & programs at the National Institute for Aviation Research (NIAR) and AMS-AM-P Chair. “These standards help define a consistent set of materials and process limits that both the user and producer agree to in support of part procurement activities. AMS-AM standards support the promotion of knowledge, standardization of practice and advancement of commerce in the emerging AM aerospace industry.”

The AMS7100 specification establishes the critical controls and requirements to produce reliable, repeatable, reproducible aerospace parts by Fused Deposition Modeling (FDM) or other material extrusion production. This procedure creates guidelines that FDM System users will follow to approve new machines, processes and materials. Specifically, this new specification covers the configuration of the machine, operating software, machine calibration, machine and build parameters, and testing methodology required to create certified additively manufactured aerospace parts.

The AMS7101 specification establishes the certification requirements for materials to be used in FDM or other material extrusion additive manufacturing production for aerospace components. This specification outlines the technical information, production guidelines and documentation requirements for FDM material manufacturer.

“Following the success and momentum of the SAE AMS-AM Metallic Materials committee, the swift efforts of the AMS-AM-P committee helped bring these groundbreaking, aerospace-grade AMS specifications to the global stakeholder community,” said David Alexander, director, SAE Aerospace Standards Program.
