[This] video below shows an actual test firing of a prototype rocket using a 3D printed liner. This, as far as we can tell, is the first time a real rocket engine has been fired with 3D printed parts.
NASA Marshall says:
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.
Yes, it really works.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
