Fired Up! We've tested a combustion chamber made using a new combination of 3-D printing techniques that breaks barriers in advanced manufacturing, by reducing time and costs involved in building rocket engine parts. In this image, we successfully hot-fire test 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.
