NASA Glenn Research Center Creates New 3D-Printed Superalloy

Researchers at NASA’s Glenn Research Center have developed a new 3D-printed superalloy, called GRX-810, that has higher heat resistance compared to current 3D-printed superalloys. In a peer-reviewed paper published in the multidisciplinary science journal Nature, Tim Smith, one of the GRX-810 inventors and the paper’s lead author, said the new superalloy can make components and parts used in aviation and space exploration stronger and more durable.

GRX-810, an oxide dispersion-strengthened alloy, was developed under NASA’s Transformational Tools and Technologies project, with support from the Ohio State University and other NASA research centers, SciTechDaily reported. The product was created using time-saving computer modeling and a laser 3D printing process that combined metals together.

Oxide dispersion-strengthened alloys can withstand over 2,000 degrees Fahrenheit, making them ideal for use as aircraft and rocket engine components. Dale Hopkins, deputy project manager of NASA’s Transformational Tools and Technologies project, describes the alloy development as a major achievement. He said GRX-810 may be “one of the most successful technology patents NASA Glenn has ever produced.”
