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.

This specification establishes process controls for the repeatable production of aerospace parts by Laser Powder Bed Fusion (L-PBF). It is intended to be used for aerospace parts manufactured using Additive Manufacturing (AM) metal alloys, but usage is not limited to such applications.

This specification is to prescribe process requirements for production (from raw materials through preparation for shipment, see 8.6) of metal powder feedstock for use in additive manufacturing of aerospace parts. This specification covers requirements for the production of metal powder for use as feedstock in additive manufacturing. Such powders may be pre-alloyed or commercially pure. This specification is not limited to a specific powder production method. It is intended to define those procedures and requirements necessary to achieve required cleanliness and performance of metal powder feedstock to be used in the manufacture of aerospace parts. This specification is intended to be used in conjunction with AMS powder specifications for additive manufacturing.

This SAE Aerospace Recommended Practice (ARP) outlines a development, design/repair, and industrial guidance for systems using additive manufacturing (AM) to respond to aircraft requirement specifications. These recommendations reflect procedures that have been effective for designing/repairing metallic alloy components.

The intended upper bound of this specification is that the particle size distribution (PSD) of powders supplied shall be <60 mesh (250 microns) and that no powder (0.0 wt.%) greater than 40 mesh (425 microns) is allowed.

This specification establishes process controls for the repeatable production of preforms/parts using the laser directed energy deposition (L-DED-) process for additive manufacturing. Preforms are intended to be used to manufacture aerospace parts, but usage is not limited to such applications. Feedstock may be either wire (for L-DED-Wire) or powder (for L-DED-Powder).

This specification covers a heat-resistant gamma titanium aluminide alloy in the form of pre-alloyed powder.

This specification covers particle size classifications and corresponding particle size distribution requirements for metal powder feedstock conforming to a classification.

This specification establishes process controls for the repeatable production of sintered parts by binder jet additive manufacturing (BJAM). It is primarily intended to be used to manufacture metallic or ceramic aerospace parts, but usage is not limited to such applications.

This specification establishes process controls for the repeatable production of aerospace parts by EB-DED-Wire. It is intended to be used for metal aerospace parts produced by additive manufacturing (AM), but usage is not limited to such applications.

This specification establishes process controls for the repeatable production of aerospace parts by Electron Beam Powder Bed Fusion (EB-PBF). It is intended to be used for aerospace parts manufactured using additive manufacturing (AM) metal alloys, but usage is not limited to such applications.

This specification establishes process controls for the repeatable production of preforms using the wire fed laser directed energy deposition (L-DED-wire) process for additive manufacturing. Preforms are intended to be used to manufacture aerospace parts, but usage is not limited to such applications.
