3D Systems has announced the successful verification of properties for NASA’s new superalloy, GRX-810. Processed by Laser Beam Powder Bed Fusion (PBF-LB) Additive Manufacturing, this oxide dispersion-strengthened alloy, developed by NASA last year, is said to demonstrate exceptional mechanical properties and resistance to extreme temperatures, making it ideal for aerospace applications.
GRX-810 is described as a “potential game-changer” for the aerospace industry. Through its oxide dispersion strengthening mechanism it is reported as offering an unparalleled combination of strength, ductility, creep life, and heat resistance. These properties make the alloy an ideal candidate for future use in critical components such as rocket engines, turbine blades, and exhaust nozzle components.

Working with material provided by NASA, 3D Systems successfully processed and tested the elevated temperature mechanical properties of GRX-810 using its Direct Metal Printing (DMP) PBF-LB platform. This verification of properties represents a major milestone, demonstrating the performance of the material across different equipment and processing parameters and further opening the door for the use of GRX-810 in various aerospace components that require superior performance to traditional nickel-based superalloys.
“The successful verification of the reported NASA GRX-810 properties is a testament to the incredible potential of this new superalloy, not only in its performance but in its capability to be produced repeatably,” stated Dr Michael Shepard, vice president, aerospace & defense segment, 3D Systems.
“Our work with this material provided by NASA underscores our commitment to pushing the boundaries of additive manufacturing and enabling the production of next-generation aerospace components. We are thrilled to be part of the early stages of this exciting development and look forward to unlocking new possibilities with GRX-810.”
