NASA has a vested interest in 3D printing. It’s already investigating food-based 3D printers, and the idea of building satellites in space with the technology. Now it’s working on 3D printed rocket parts.

Over the summer, NASA has been testing a 3D printed rocket injector that could withstand the extreme heat of burning rocket fuel. In a test at the end of June, they fired the rocket and found that the 3D printed rocket parts performed admirably.

Here’s what NASA has to say about it:

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.

Of course, there’s a lot of work to be done before NASA can use 3D printed parts on actual spacecraft. Even so, this breakthrough represents a way for the space agency to cheaply make sophisticated parts. It should also cut down on the time required to reiterate rocket design.

    let’s all just bite the bullet and call 3d printers what they really are; replicators. now science can move on and make me a light saber.
