Machine Qualification for Fusion-Based Metal Additive Manufacturing
- Aerospace Material Specification
Published August 17, 2022 by SAE International in United States
This standard has notes/guidance narratives interspersed throughout. These notes/guidance narratives are identified by a header and by text in italics.
This standard defines a series of requirements that results in a specific AM machine qualified to produce material (see GN1) in compliance to an aerospace materials specification. The machine control and/or configuration types are discussed in the next sections. The industry (including AIA and ASTM) generally acknowledges that there are three qualification milestones for AM machines; nevertheless, this document will focus only on the initial two stages, namely:
Installation Qualification (IQ): Producing objective evidence to show that all key aspects of the process equipment and ancillary system installation adhere to the AM Part Producer’s specification and that the recommendations of the supplier of the equipment are suitably considered; this is tied to a specific machine serial number.
Operational Qualification (OQ): Establishing sufficient process control to maintain stable material performance and demonstrating that the material specification requirements can be met; this is also tied to a specific machine serial number (see GN2).
Metal additive manufacturing (AM) machine qualification requirements are process intensive. This document is intended to provide technical information on the requirements for qualifying a metal AM machine that is suitable for producing aerospace-grade material. Thus, the intended users of this document are organizations that will directly produce these aerospace-grade parts, or by those responsible for overseeing their production and therefore have a vested interest in verifying the performance of additive manufacturing machines.

Welcome to the SAE AMS AM, Additive Manufacturing public forum area.Scope: AMS AM is a technical committee in SAE’s Aerospace Materials Systems Group with the responsibility to develop and maintain aerospace material and process specifications and other SAE technical reports for additive manufacturing, including precursor material, additive processes, system requirements and post-build materials, pre-processing and post-processing, non-destructive testing and quality assurance.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
