Materials expansion includes high-temperature nickel alloys, aluminum, titanium, copper, refractory metals, carbon-fiber thermoplastics, biocompatible resins, and engineered porosity/surface textures.
Broadening materials availability is critical to expanding AM beyond its 'titanium and Inconel' perception. Copper AM (for EV heat exchangers), refractory metals (nuclear, hypersonic), and carbon-fiber thermoplastics (LFAM structural tooling) open new markets.
- 01NASA Glenn — NASA Licenses 3D-Printable Superalloy to Benefit US Economy2024-05-09
NASA licenses GRX-810, a laser-PBF oxide-dispersion-strengthened nickel-base superalloy for rocket and jet hot-section parts above 2,000 °F, co-exclusively to Carpenter Technology, Elementum 3D, Linde Advanced Material Technologies, and Powder Alloy Corporation. Supports the high-temperature nickel-alloy portion of this signal.
- 02NASA Marshall — NASA Additive Manufacturing Project Shapes Future for Agency, Industry Rocket Makers2024-08-01
RAMPT project summary: 500 hot-fire tests of printed injectors, nozzles, and chambers using newly developed extreme-environment alloys, and delivery of a refined GRCop-42 copper alloy to industry (used in Relativity Space's 3D-printed rocket, March 2023). Supports the copper portion.
- 03America Makes — America Makes Announces Winners of Powder Alloy Development for Additive Manufacturing (PADAM) Project Totaling $6M2024-07-22
Awards under Topic 1, High-Temperature Refractory Alloys, include Maturing AM Technology for C-103 (niobium alloy) in Hypersonics and Space (MATCHAS), led by Castheon with 6K Additive, ATI Specialty Alloys, Lockheed Martin, and NASA Glenn on the team. Supports the refractory-metals portion. Link-health: americamakes.us serves a Cloudflare challenge to automated clients (200 to browser user agents).
- 04DOE OSTI / ORNL — Howard, Parker & Yu, Progress and Challenges of Additive Manufacturing of Tungsten and Alloys as Plasma-Facing Materials (Materials 17(9))2024-04-28
DOE Fusion Energy Sciences-sponsored ORNL review of laser powder bed fusion, electron beam melting, and directed energy deposition of tungsten for fusion plasma-facing components, documenting recent progress and the remaining cracking and irradiation gaps. Supports the refractory-metals (nuclear/fusion) portion.
- 05NASA Marshall — NASA's Innovative Rocket Nozzle Paves Way for Deep Space Missions2023-10-19
RAMFIRE: NASA and Elementum 3D developed the weldable, heat-resistant A6061-RAM2 aluminum for laser-powder DED rocket nozzles, hot-fire tested at Marshall in 2023. Supports the aluminum portion; it predates the 2024-2025 window and is cited as the enabling development.
