NASA designed a rocket engine injector using design features that employed a 3-D printer.

The device is highly complex and sends propellant into the engine. The 3-D printer built each part by layering metal powder and fusing it together with a laser in a process known as selective laser printing. The new part was similar in size to those that power small engines but similar in design to ...
