Some call it “additive manufacturing,” and some call it “3D printing.” Whatever you call it, the technique of building things by layering material according to a 3D computer design is one of the hottest things going. People are doing it with plastics and metals and trying it with food and even human “tissue” in a race to build the perfect Star Trek replicator.

At Huntsville’s Marshall Space Flight Center, NASA scientists and engineers from the company Made in Space are building the first 3D printer to send to space. It will go the International Space Station next year aboard a SpaceX rocket. In the 2:30 video below, watch the machine build a small plastic clip that’s used frequently on the space station.

Printing in space will allow astronauts to replace a variety of small parts that break and save NASA the trouble and expense of launching multiple spares of multiple parts.
