General Agreement: Material Specification Template
2024-09-19
WIP
GAAM-M24A
Create a template for material specifications that provides the minimum recommended details that should be included in all material specifications. This will not be material specific but will be general in scope and can be used as guidance/a baseline for material specification drafting, but may not include all aspects that should be included in a specific material specification.

WIP
AMS7073
This specification covers a corrosion-resistant steel alloy in the form of parts produced by laser-powder bed fusion (L-PBF) that are subjected to stress relieved, solution, and precipitation heat treated condition. The application is for parts typically requiring corrosion resistance and high strength up to 600 °F (316 °C) with good ductility and strength, but usage is not limited to such applications. This specification will be Additive Manufacturing version of AMS5659 specification.

Machine Requalification Considerations for Fusion-Based Metal Additive Manufacturing
2024-05-09
CURRENT
ARP7064
This document defines a recommended practice for addressing metal additive manufacturing (AM) machine requalification for all fusion-based metal AM machines. In general, this applies to powder bed fusion (PBF) and wire- or powder-fed directed energy deposition (DED) technologies. Plasma, electron beam, or lasers are applicable energy source(s).

Machine Qualification for Fusion-Based Metal Additive Manufacturing
2024-02-16
WIP
AMS7032A
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.

Titanium Alloy Preforms from Plasma Arc Directed Energy Deposition Additive Manufacturing on Substrate, Ti-6Al-4V, Stress Relieved
2024-01-19
WIP
AMS7004A
This specification covers preforms fabricated up through 5.5 inches (140 mm) inclusive in deposition width thickness (see 8.2.5) using a Plasma Arc Directed Energy Deposition (PA-DED) additive manufacturing process on a Ti-6Al-4V substrate that are subjected to post-deposition stress relief heat treatment. This is a wire fed additive manufacturing process. If required by the CEO, preforms may require subsequent machining to meet requirements for their intended final part application.

In-Situ Process Monitoring Considerations for Metal Fusion Additive Manufacturing
2023-12-01
WIP
ARP7068
This document defines a recommended practice for addressing metal additive manufacturing (AM) In-Situ Process Monitoring (ISPM) for all fusion-based metal AM machines. In general, this applies to powder bed fusion (PBF) and wire- or powder-fed directed energy deposition (DED) technologies. Plasma, electron beam or lasers are applicable energy source(s).

Additional Guidance for Metal Powder Feedstock for Additive Manufacturing
2023-10-11
WIP
AIR7359
This document is a collection of comments on topics relevant to AMS powder feedstock production and procurement. In some instances it provides explanation of characteristics not controlled in AMS-AM powder feedstock specifications and the rationale for exclusion (e.g. limitation of applicability or maturity of standardized inspection techniques). In other cases it provides additional context on the reason for structuring requirements in AMS documents one way instead of other available options.
