Waspie_Dwarf Posted July 15, 2013 #1 Share Posted July 15, 2013 Nasa tests 3D-printed rocket engine fuel injector Nasa has announced it has successfully tested a 3D-printed rocket engine part.The US space agency said that the injector component could be made more quickly and cheaply using the technique. The part is used to deliver liquid oxygen and hydrogen gas to an engine's combustion chamber. Read more... Link to comment Share on other sites More sharing options...
Waspie_Dwarf Posted July 24, 2013 Author #2 Share Posted July 24, 2013 Hot-Fire Tests Show 3-D Printed Rocket Parts Rival Traditionally Manufactured Parts What can survive blazing temperatures of almost 6,000 degrees Fahrenheit without melting? What did not break apart at extreme pressures? What is made by a new process that forms a complex part in just one piece? What takes less than three weeks to go from manufacturing to testing? What can reduce the costs of expensive rocket parts by 60 percent or more?Answer: 3-D printed parts Engineers know that 3-D printed rocket parts have the potential to save NASA and industry money and to open up new affordable design possibilities for rockets and spacecraft. But until recently, no one had tested rocket parts critical to engine combustion in a hot-fire environment. Read more... Link to comment Share on other sites More sharing options...
Waspie_Dwarf Posted July 24, 2013 Author #3 Share Posted July 24, 2013 Test Firing Go Pro VideoWatch a video that puts you in the test stand. This video gives you a blazing view of the one of the first tests of a 3-D printed rocket injector on June 27, 2013, in Test Stand 115 at NASA's Marshall Space Flight Center in Huntsville, Ala. Propulsion engineers used the tests to compare the performance of a 3-D printed rocket injector to an injector made with multiple parts and traditional welds. During the extreme temperatures and pressures of the hot firing, the 3-D printed part performed as well as the traditionally manufactured part. This test included a 3-D printed liner.

Waspie_Dwarf Posted August 27, 2013 Author #4 Share Posted August 27, 2013 NASA Tests Limits of 3-D Printing with Powerful Rocket Engine Check The largest 3-D printed rocket engine component NASA ever has tested blazed to life Thursday, Aug. 22 during an engine firing that generated a record 20,000 pounds of thrust.This test is a milestone for one of many important advances the agency is making to reduce the cost of space hardware. Innovations like additive manufacturing, or 3-D printing, foster new and more cost-effective capabilities in the U.S. space industry. Read more...
