NASA, Industry Test "3D Printed" Rocket Engine Injector | History 2[+or less 3].0 | Scoop.it

NASA and Aerojet Rocketdyne recently finished testing a rocket engine injector made through additive manufacturing, or 3-D printing.
The series of tests demonstrated the ability to design, manufacture and test a critical rocket engine component using selective laser melting manufacturing technology -- a method that employs high-powered laser beams to melt and fuse fine metallic powders into three dimensional structures.
This type of injector manufactured with traditional processes would take more than a year to make, but with these new processes it can be produced in less than four months, with a 70 percent reduction in cost.
