NASA tests first 3D printed rocket engine part made with two different metal alloys 3D Printing Processes
NASA tests conducted by engineers at NASA’s Marshall Space Flight Center in Huntsville, focused on NASA’s first 3D printed rocket engine prototype part made of two different metal alloys through an innovative advanced manufacturing process. NASA has been making and evaluating durable 3D printed rocket parts made of one metal, but the technique of 3D printing, or additive manufacturing, with more than one metal, is significantly more difficult and has not yet been achieved with any commercially available technology.
