NASA alloy suitable for Velo3D printers

Velo3D says that a NASA-developed copper-chromium-niobium alloy can now be used with its Sapphire range of 3D printers.

GRCop-42 alloy is suitable for parts requiring high-strength and high-conductivity, such as rocket engine combustion chambers with regenerative cooling. On Velo3D’s printers it can produce parts with oxidation resistance and high creep strength at temperatures as high as 1400⁰F, the company says.

“We’ve had extensive demand for Sapphires and Sapphire XCs that can print GRCop-42 and we’ve tested it to ensure it can achieve the same high-quality builds as our other offered materials,” said said Benny Buller, Velo3D CEO and Founder.
