3D打印火箭部件和宇宙飞船的未来
Future lunar landers might come equipped with 3D printed rocket engine parts that help bring down overall manufacturing costs and reduce production time. NASA is investing in advanced manufacturing – one of five industries of the future – to make it possible.
Through a series of hot-fire tests in November, NASA demonstrated that two additively manufactured engine components – a copper alloy combustion chamber and nozzle made of a high-strength hydrogen resistant alloy – could withstand the same extreme combustion environments that traditionally manufactured metal structures experience in flight.

未来的月球着陆器可能会配备3D打印的火箭发动机零件，以帮助降低总体制造成本并减少生产时间。 NASA正在投资于先进制造业（未来的五个行业之一）以使其成为可能。
通过11月的一系列热燃测试，NASA证明了两种额外制造的发动机部件——一个铜合金燃烧室和由高强度抗氢合金制成的喷嘴——可以与传统制造的金属结构在飞行中经受同样的极端燃烧环境。
