Sparks Fly as NASA Pushes the Limits of 3-D Printing Technology

NASA has successfully tested the most complex rocket engine parts ever designed by the agency and printed with additive manufacturing, or 3-D printing, on a test stand at NASA's Marshall Space Flight Center in Huntsville, Alabama.

NASA engineers pushed the limits of technology by designing a rocket engine injector --a highly complex part that sends propellant into the engine -- with design features that took advantage of 3-D printing. To make the parts, the design was entered into the 3-D printer's computer. The printer then built each part by layering metal powder and fusing it together with a laser, a process known as selective laser melting.
