NASA STTR Award Backs Cold Spray Research for GRX-810 - 3D Printing Industry NASA STTR Award Backs Cold Spray Research for GRX-810 Home - NASA STTR Award Backs Cold Spray Research for GRX-810 A NASA -funded collaboration between the University of Utah , the Pennsylvania State University (PSU), and Colorado-based Elementum 3D is working to unlock reliable manufacturing and repair pathways for GRX-810, a high-performance alloy designed for the extreme heat and reactive conditions inside rocket engines.
The project is supported through NASA’s Small Business Technology Transfer (STTR) Phase I program, a federal funding mechanism designed to accelerate early-stage technology development. At its technical core is cold spray additive manufacturing, a process that propels metal particles at high velocities to progressively build dense coatings or bulk structures without the thermal damage associated with fusion-based methods.
The industries with the most direct stake in this research are aerospace, space, defense, and energy, sectors defined by components that must perform reliably under extreme conditions. A NASA-Developed Alloy and the Bonding Problem at Its Core The material at the center of the project is GRX-810, recognized as NASA’s Commercial Invention of the Year.
Developed to withstand sustained exposure to extreme temperatures and oxidative environments, the alloy has demonstrated strong performance credentials, yet the fundamental behavior of its particles during cold spray deposition remains insufficiently understood. Establishing that understanding is a prerequisite for building the repeatable, scalable manufacturing and repair processes the aerospace and defense sectors require.
The collaboration is structured around complementary expertise. Elementum 3D provides GRX-810 feedstock material and contributes an applied manufacturing perspective that grounds the research in industrial relevance. Penn State leads cold spray process development, focusing on how deposition parameters translate into structural outcomes.

The University of Utah’s STARS Lab, directed by Dr. Suhas Eswarappa Prameela within the Department of Materials Science and Engineering, approaches the problem at the particle level, using a Laser-Induced Particle Impact Test system to isolate and examine the variables governing whether individual particles bond, deform, or rebound on contact.
Particle chemistry, microstructure, surface condition, impact velocity, and temperature all factor into that outcome, and mapping their combined influence is the scientific foundation on which full-scale process optimization will depend. “Complex problems like these cannot be solved in isolation,” Dr. Prameela said. “Engaging with people who bring different tools, perspectives, and expertise is essential.
” Phase I covers 13 months, with a Phase II award possible for further scale-up. The end goal is a manufacturing and repair pathway for extreme-environment components with direct relevance to NASA’s space programs and future deep-space propulsion systems.
Closing the Manufacturing Gap for a Next-Generation Alloy GRX-810 is an oxide dispersion-strengthened alloy developed at NASA’s Glenn Research Center that has redefined what high-temperature materials can deliver. In an interview with Principal Engineer Paul Gradl , he explained the alloy achieves over 1,000 times improvement in creep resistance at temperatures around 1,100°C.
GRX-810 ’s combination of strength, ductility, creep life, and heat resistance is unmatched among available superalloys. Commercialization has already begun: 3D Systems validated the alloy’s properties on a commercial Direct Metal Printing platform , and Powder Alloy Corporation moved to distribute it for satellite components, spacecraft structures, and propulsion systems.
But material availability and manufacturing capability are not the same thing. GRX-810 has been qualified almost exclusively for laser-based additive processes, leaving cold spray, the one technique that can both fabricate and repair components in service, without the scientific foundation it needs to be used reliably. For reusable propulsion systems, where extending component life directly reduces mission costs, that is a big gap.
The U.S. Department of Defense has already backed cold spray field demonstrations in extreme environments through its Point of Need Manufacturing initiative , confirming the technology’s readiness for operational use. What remains missing is the particle-level understanding of how GRX-810 specifically behaves under those conditions, and without it, neither manufacturing nor repair at scale is viable.
That is precisely what this collaboration sets out to establish. 3D Printing Industry is inviting speakers for its 2026 Additive Manufacturing Applications (AMA) series, covering Energy, Healthcare, Automotive and Mobility, Aerospace, Space and Defense, and Software.

In January 2026, DOE Policy Flash PF-2026-30 wiped out every 15% and 10% indirect cost cap the administration had imposed in 2025 — because H.R. 6938 ordered it to. The same law froze indirect policy at NSF, Commerce and NASA. But OMB's sweeping new grants rule quietly reopens the fight through the back door. Here is what changed, what money recipients can claw back, and how to protect your indirect recovery going forward.
Read articleFor Program Year 2026, NASA replaced its single January SBIR/STTR solicitation with a Broad Agency Announcement that releases topics in appendices throughout the year — with proposal limits resetting each time. Phase I awards now run up to $225,000. Here is what the structural shift means, why it favors prepared companies, and how to build a year-round SBIR strategy around it.
Read articleNASA shifted its SBIR/STTR program from a single-cycle solicitation to a Broad Agency Announcement on April 17, 2026 — valid through September 30, 2027 — with subtopics released in rolling appendices. The structural change ends 41 years of predictable January-to-March deadlines and forces space startups to rebuild their proposal pipelines around continuous monitoring rather than annual sprints.
