Velo3D’s Matt Karesh highlights GRCop-42, a NASA-developed copper alloy prized for its high strength and thermal conductivity.
Matt shows off a regenerative rocket engine we printed on a Velo3D Sapphire Metal AM printer that uses fuel to cool the thrust chamber, which in turn helps the fuel burn more efficiently.
He also shows off a much larger version in Inconel 718.
