Preparations for Next Moonwalk Simulations Underway (and Underwater)
GRX-810 is a new metal alloy developed by NASA for 3D printing parts that can withstand the extreme temperatures of rocket engines, allowing affordable printing of high-heat parts.NASA Until now, additive manufacturing, commonly known as 3D printing, of engine components was limited by the lack of affordable metal alloys that could withstand the extreme temperatures of spaceflight. Expensive metal alloys were the only option for 3D printing engine parts until NASA’s Glenn Research Center in Cleveland, Ohio, developed the GRX-810 alloy.
The primary metals in the GRX-810 alloy include nickel, cobalt, and chromium. A ceramic oxide coating on the powdered metal particles increases its heat resistance and improves performance. Known as oxide dispersion strengthened (ODS) alloys, these powders were challenging to manufacture at a reasonable cost when the project started.
However, the advanced dispersion coating technique developed at Glenn employs resonant acoustic mixing. Rapid vibration is applied to a container filled with the metal powder and nano-oxide particles. The vibration evenly coats each metal particle with the oxide, making them inseparable. Even if a manufactured part is ground down to powder and reused, the next component will have the qualities of ODS.
The benefits over common alloys are significant – GRX-10 could last up to a year at 2,000°F under stress loads that would crack any other affordable alloy within hours. Additionally, 3D printing parts using GRX-810 enables more complex shapes compared to metal parts manufactured with traditional methods.
Elementum 3D, an Erie, Colorado-based company, produces GRX-810 for customers in quantities ranging from small batches to over a ton. The company has a co-exclusive license for the NASA-patented alloy and manufacturing process and continues to work with the agency under a Space Act Agreement to improve the material.
“A material under stress or a heavy load at high temperature can start to deform and stretch almost like taffy,” said Jeremy Iten, chief technical officer with Elementum 3D. “Initial tests done on the large-scale production of our GRX-810 alloy showed a lifespan that’s twice as long as the small-batch material initially produced, and those were already fantastic.”
Commercial space and other industries, including aviation, are testing GRX-810 for additional applications. For example, one Elementum 3D customer, Vectoflow, is testing a GRX-810 flow sensor. Flow sensors monitor the speed of gases flowing through a turbine, helping engineers optimize engine performance. However, these sensors can burn out in minutes due to extreme temperatures. Using GRX-810 flow sensors could improve airplane fuel efficiency, reduce emissions and hardware replacements.
Working hand-in-hand with industry, NASA is driving technology developments that are mutually beneficial to the agency and America’s space economy. Learn more: https://spinoff.nasa.gov/

NASA has demonstrated a breakthrough in 3D-printable high-temperature materials that could lead to stronger, more durable parts for airplanes and spacecraft. Credit: NASA/Jordan Salkin NASA’s Inventions and Contributions Board (ICB) has awarded Commercial Invention of the Year to NASA Glenn Research Center’s GRX-810: A 3D Printable Alloy Designed for Extreme Environments.
NASA Alloy GRX–810, an oxide dispersion strengthened (ODS) alloy, can endure temperatures over 2,000 degrees Fahrenheit. It is more malleable and can survive more than 1,000 times longer than existing state-of-the-art alloys. This new alloy can be used to build aerospace parts for high-temperature applications, like those inside aircraft and rocket engines, because ODS alloys can withstand harsher conditions before reaching their breaking point.
The NASA Glenn team of inventors includes Dr. Timothy Smith (co-lead), Dr. Christopher Kantzos (co-lead), Robert Carter, and Dr. Michael Kulis.
Four American companies have been granted co-exclusive licenses to produce and market GRX-810 material. All four have replicated NASA Glenn’s patented process and are selling fully coated materials. This benefits the United States economy as a return on investment of taxpayer dollars.

Additionally, the ICB selected NASA Glenn’s High-Rate Delay Tolerant Networking (HDTN) project for an honorable mention in the Software of the Year category. HDTN is a protocol suite that extends terrestrial internet principles to the space environment, creating a high-speed data transfer path for spacecraft and different communication systems. It is an optimized version of the DTN standard for high-rate radio frequency and optical links.
The ICB reviews and recommends awards for significant scientific and technical contributions to the agency’s aeronautical and space activities. These awards recognize technologies that not only advance NASA’s mission but also benefit the public through commercialization.

Credit: NASA U.S. Transportation Secretary and acting NASA Administrator Sean Duffy joined President Donald J. Trump at the White House Wednesday for the historic signing of the Executive Order (EO), “Enabling Competition in the Commercial Space Industry.”
“People think the Department of Transportation (DOT) is just planes, trains, and automobiles – but we have a critical role to play in unlocking the final frontier. By slashing red tape tying up spaceport construction, streamlining launch licenses so they can occur at scale, and creating high-level space positions in government, we can unleash the next wave of innovation. At NASA, this means continuing to work with commercial space companies and improving our spaceports’ ability to launch,” said Duffy. “Thanks to the leadership of President Trump, we will enable American space competitiveness and superiority for decades to come. I look forward to leveraging my dual role at DOT and NASA to make this dream a reality.”
The EO will enable a competitive launch marketplace and substantially increase commercial space launch cadence and novel space activities by 2030.
“The FAA strongly supports President Trump’s Executive Order to make sure the U.S. leads the growing space economy and continues to lead the world in space transportation and innovation,” said FAA Administrator Bryan Bedford. “This order safely removes regulatory barriers so that U.S. companies can dominate commercial space activities.”
Executive Order highlights:
The “Enabling Competition in the Commercial Space Industry” EO will help to:
Streamline commercial license and permit approvals for United States-based operators. This includes eliminating regulatory barriers and expediting environmental reviews for commercial launches and reentries. Cut unnecessary red tape to make it easier to build new spaceports in the U.S. where more commercial space operations will be launched from. To ensure this Next Generation Spaceport Infrastructure, duplicate review process will be eliminated, and environmental reviews will be expedited. Promote new space activities like in-space manufacturing and orbital refueling through a streamlined framework. Expediting and streamlining authorization for this Novel Space Activity is essential to American space competitiveness and superiority. Establish a new position in the Office of the Secretary with the responsibility of advising the Secretary of Transportation on fostering innovation and deregulation in the commercial space industry. The FAA’s associate administrator for Commercial Space Transportation also will be a senior executive non-career employee, and the Office of Space Commerce will be elevated into the Office of the Commerce Secretary. Mitigate the risk of the United States losing its competitive edge in the commercial space industry by dismantling regulatory barriers that prevent rapid innovation and expansion.
