[QUOTE="Opmmur, post: 71666, member: 13"] [SIZE=6][B]3-D-printed rocket part passes major NASA test[/B][/SIZE] Miriam Kramer Space.com [IMG]http://msnbcmedia2.msn.com/j/streams/2013/July/130718/6C8308555-3d-printer-rocket-part.blocks_desktop_small.jpg[/IMG] NASA Glenn Research Center Task lead Tyler Hickman, in red shirt, and technicians inspect the 3-D-printed rocket injector assembly as it’s installed in the Rocket Combustion Laboratory at NASA’s Glenn Research Center. A 3-D-printed rocket engine injector has passed a major NASA test, potentially heralding a new age of propulsion-system manufacturing, space agency officials say. NASA and Florida-based company Aerojet Rocketdyne put the injector — which was built using [URL='http://www.livescience.com/topics/3d-printing/']3-D printing[/URL] (also called "additive manufacturing") technology — through a series of hot-fire trials, agency officials announced last week. "Hot-fire-testing the injector as part of a rocket engine is a significant accomplishment in maturing additive manufacturing for use in rocket engines," Carol Tolbert, manager of the Manufacturing Innovation Project at NASA's Glenn Research Center in Cleveland, Ohio, where the tests were conducted, said in a statement. [[URL='http://www.technewsdaily.com/5242-incredible-3d-printed-products.html']10 Amazing 3-D-Printed Objects[/URL]] "These successful tests let us know that we are ready to move on to demonstrate the feasibility of developing full-size, additively manufactured parts," Tolbert added. Aerojet Rocketdyne crafted the engine injector using high-powered lasers that liquefied and fused metallic powders into the proper structure. Rocket engine injectors typically take a year or more to build. Employing 3-D printing technology can reduce this to less than four months while also cutting costs by 70 percent, NASA officials said. "NASA recognizes that on Earth and potentially in space, additive manufacturing can be [URL='http://www.space.com/21313-nasa-3d-printing-space-exploration.html']game-changing for new mission opportunities[/URL], significantly reducing production time and cost by 'printing' tools, engine parts or even entire spacecraft," Michael Gazarik, NASA's associate administrator for space technology in Washington, D.C., said in a statement. "3-D manufacturing offers opportunities to [URL='http://www.space.com/22001-3d-printed-rocket-engine-part-test.html#']optimize[/URL] the fit, form and delivery systems of materials that will enable our space missions while directly benefiting American businesses here on Earth," he added. NASA's interest in 3-D printing appears to be strong and growing. For example, the space agency is partnering with California company Made in Space to send a [URL='http://www.space.com/20658-3d-printer-international-space-station-2014.html']3-D printer to the International Space Station[/URL] next year. And NASA recently funded the development of a prototype "3-D pizza printer" that could help feed astronauts on long space journeys, such as the 500-day trek to Mars. 3-D printing has been used to craft certain rocket parts before, but usually this form of manufacturing is employed to build less critical components of the complex machines, Aerojet Rocketdyne additive manufacturing program manager Jeff Haynes said. "The injector is the heart of a rocket engine and represents a large portion of the resulting cost of these [URL='http://www.space.com/22001-3d-printed-rocket-engine-part-test.html#']systems[/URL]," Haynes said in a statement. "Today, we have the results of a fully additive manufactured rocket injector with a demonstration in a relevant environment." [/QUOTE]
