“SAE has always been a great resource for specifications that we can use to design and

qualify our parts. We are happy to see that SAE is taking the lead in additive manufacturing by developing specifications with associated design values.”

ENGINEERS ON EARTH.


SAE International is the Standards Development Organization uniquely dedicated to solving the toughest technical challenges of the aerospace and ground vehicle sectors through industry-driven, consensus-based standards development.

Additive manufacturing (AM), sometimes referred to as three dimensional (3D) printing, is emerging as a transformational technology in the aerospace and defense industry. Industry standards are necessary to establish a material qualification system to assist with addressing global aerospace regulatory requirements.

Regulatory agencies increasingly rely on industry standards to support regulations and acceptable means of compliance. In October 2015, the Federal Aviation Administration (FAA) issued a tasking request to SAE to “develop Aerospace Materials Specifications, process standards, Aerospace Recommended Practices, and other related standards … to assist the FAA in developing guidance material for AM certification.”

CURRENTLY:

550+ members from 24 countries

24 specs published, 30 specs and guidance documents under development

Membership includes airlines, aircraft/spacecraft/engine OEMs, Tier 1 & 2 suppliers, equipment suppliers, material suppliers, service providers, test laboratories, defense agencies, regulatory authorities

• Establishing appropriate requirements and controls to ensure quality and consistency of final product

• Providing statistically derived specification minimum values for the purchase of consistent material and the validation of AM processes

• Enabling public material property databases with verifiable pedigree

• Promoting the fabrication of consistently repeatable AM parts

In order for structural parts produced by AM processes to move from point design to material qualification, the materials and processes used to manufacture AM components must be under documented control. SAE’s AMS-AM Committee is developing a series of feedstock material and AM processing specifications required to support regulations governing the certification of aircraft. An integral part of specification development is deriving specification minimum values for the acceptance of feedstock material and the qualification of AM processes.

WHY IT’S IMPORTANT

SAE Aerospace Material Specifications (AMS) support the certification of aerospace critical parts by protecting the integrity of material property data and providing traceability within the supply chain. Industry consensus specifications for additive manufacturing of aerospace parts are an enabler for the migration from part qualification to material qualification. Key principles addressed by AMS specifications include:

“ The SAE AMS AM committee allows industry members to drive specifications in the direction of a constantly changing and maturing technology. AM has revolutionized our industry, and the SAE AMS AM committee has been at the forefront. Since we have members from across the entire aerospace supply chain, we can focus on building a strong specification universe from material to production to part. On a personal level, participating in the committee has grown my network and given me exposure to parts of the industry I might otherwise not have interacted with. Being a part of the committee from the beginning has allowed me to grow professionally, and I have a greater perspective of the industry as a whole because of the deep technical expertise we have among our members.”

AMS-AM ORGANIZATIONAL STRUCTURE

SAE’S ADDITIVE MANUFACTURING COMMITTEE

Established in July 2015, SAE AMS-AM, Additive Manufacturing, is a technical committee responsible for developing and maintaining aerospace material and process specifications for additive manufacturing, including precursor materials, additive processes, system requirements and post-build materials, pre-processing and post-processing, nondestructive testing, and quality assurance.

WORKING GROUPS


• Develop Aerospace Material Specifications (AMS) for the procurement of additive precursor and manufactured materials including metals, plastics, ceramics, composites, and hybrids made by additive technologies.

• Publish technical reports for processing and fabrication of aerospace end products from AM materials.

• Further the adoption of industry sponsored material specifications through coordination with Metallic Materials Properties Development and Standardization Handbook (MMPDS), Composite Materials Handbook (CMH-17), ASTM Committee F42 on Additive Manufacturing, AWS D20, Nadcap Welding Task Group, other AMS committees and associated organizations.

• Establish a system to ensure material specifications are controlled and traceable to statistically substantiated data analyzed by documented procedures.

AMS-AM COMMITTEE OBJECTIVES:

“ AM users and producers benefit from implementing SAE AMS AM standards. The standards help define a consistent set of material, process, and process limits which both the user and producer agree to in support of part procurement activities. SAE AMS AM standards support the promotion of knowledge, standardization of practice, and advancement of commerce in the emerging AM aerospace industry. We are collaborating with regulatory bodies (ex. FAA, Air Force, NASA) , material and machine manufacturers, AM suppliers and users to develop relevant specifications needed to support the qualification and certification of aerospace parts. ”

J. Hector Sandoval, Lockheed Martin, AMSAM Chair

SAE AMS-AM subcommittees are developing material specifications for the procurement of both metallic and polymer additive precursor and manufactured materials. Process specifications with sufficient controls and traceability for safety-critical parts are also under development.

The Non-Metallic Subcommittee was created at the request of the International Air Transport Association (IATA) Engineering & Maintenance Group.

SAE’s AMS-AM Data Management Subcommittee released Data Submission Guidelines describing the minimum data requirements necessary to generate specification minimum values for both metals and polymers.

Established in 2018, the Additive Manufacturing for Repair Working Group is developing material and process specifications for materials used in aerospace repair applications.
