NASA is breaking ground in the world of additive manufacturing with the Low Cost Upper Stage-Class Propulsion project. Recently, the agency successfully hot-fire tested a combustion chamber at NASA’s Marshall Space Flight Center (nasa_marshall) in Huntsville, Alabama made using a new combination of 3-D printing techniques. In this image, NASA successfully hot-fire tests a 3-D printed copper combustion chamber liner with an E-Beam Free Form Fabrication manufactured nickel-alloy jacket. The hardware must withstand extreme hot and cold temperatures inside the engine as extremely cold propellants are heated up and burned for propulsion.
