Aerospace AM: 3D Systems confirms performance of NASA’s New Super Alloy GRX-810

Last year, NASA made headlines with the launch of an oxide dispersion strengthened (ODS) alloy. Named GRX-810, the new metal alloy is said to withstand extreme temperatures (up to 2,000 degrees Fahrenheit = 1093,333°C), survive more than 1,000 times longer than existing aerospace alloys, therefore withstand harsher conditions before reaching their breaking point.

This combination of strength, ductility, creep life, and heat resistance makes 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, the machine manufacturer 3D Systems has successfully processed and tested the elevated temperature mechanical properties of GRX-810 using its Direct Metal Printing (DMP) 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 super alloys.

 “The successful verification of the reported NASA GRX-810 properties is a testament to the incredible potential of this new super alloy, not only in its performance but in its capability to be produced repeatably,” said Dr. Michael Shepard, vice president, aerospace & defense segment, 3D Systems. ”[…] We are thrilled to be part of the early stages of this exciting development and look forward to unlocking new possibilities with GRX-810.”
