Could a rocket engine be built through 3-D printing technology? We've moved a step closer to finding out with recent test firings. Additive manufacturing, or 3-D printing, is a key technology for enhancing space vehicle designs and manufacturing and enabling more affordable exploration missions. During a series of test firings at NASA’s Marshall Space Flight Center (nasa_marshall) in Huntsville, #Alabama, 3-D printed rocket engine parts worked together successful under the same conditions experience inside rocket engines used in space. The turbopump was tested at full power, pumping 1,200 gallons of liquid hydrogen per minute and the injector produced 20,000 pounds of thrust.
