Continuous, Closed-Loop Process Requirements for the Reuse of Used Powder in Additive Manufacturing of Aerospace Parts

2022-06-20
WIP
AMS7052
This specification prescribes process requirements for the operation of an additive manufacturing machine or ancillary apparatus to maintain continuous, closed-loop powder handling and reconditioning of used, metal powder for reuse in subsequent additive manufacturing of aerospace parts. Such powders may be pre-alloyed or commercially pure. This specification is not limited to a specific additive manufacturing process workflow that both generates used powder and consumes reuse powder. It is intended to define those procedures and requirements necessary to achieve required cleanliness and performance of metal powder feedstock when continuously used and processed within the same additive manufacturing process and equipment. This specification is intended to be used in conjunction with relevant AMS powder specifications and AMS process specifications for additive manufacturing.

Laser-Powder Bed Fusion (L-PBF) Produced Parts, Nickel Alloy, Corrosion- and Heat-Resistant, 62Ni - 21.5Cr - 9.0Mo - 3.65Nb Stress Relieved, Hot Isostatic Pressed and Solution Annealed

2022-05-16
CURRENT
AMS7000A
This specification covers a corrosion and heat-resistant nickel alloy in the form of parts produced by laser-powder bed fusion (L-PBF) that are subjected to post-deposition stress relief (SR), hot isostatic press (HIP) and solution anneal operations. Parts may require subsequent machining or surface finishing to meet specific application requirements.

Process Requirements for Production of Metal Powder Feedstock for Use in Additive Manufacturing of Aerospace Parts

2022-05-16
CURRENT
AMS7002A
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.

Batch Processing Requirements for the Reuse of Used Powder in Additive Manufacturing of Aerospace Parts

2022-03-29
CURRENT
AMS7031
This specification prescribes process requirements for batch processing of used, metal powder originating from an existing additive manufacturing process workflow for reuse in subsequent additive manufacturing of aerospace parts in non-closed loop additive manufacturing machines. Such powders may be pre-alloyed or commercially pure. This specification is not limited to a specific additive manufacturing process workflow as the originating source of material to be reused. It is intended to define those procedures and requirements necessary to achieve required cleanliness and performance of metal powder feedstock to be reintroduced into the same additive manufacturing process from which such powder originated. This specification is intended to be used in conjunction with relevant AMS powder specifications and AMS process specifications for additive manufacturing.

Laser Directed Energy Deposition Additive Manufacturing Process (L-DED)

2021-10-28
CURRENT
AMS7010A
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).
