3-D printed engines could support human missions to deep space. In NASA's latest exploration of combining 3-D printing and space travel, the agency ran tests on the largest ever 3-D printed rocket engine component at the Marshall Space Flight Center. The engine part was a complex subscale injector, similar in size to those that power small rocket engines. When an engine is firing, the injector delivers propellants, which provides power and thrust to get the rocket off the ground. NASA tested the...
