When traveling to other planetary bodies, each and every pound of cargo matters. If we can reduce the weight by building tools once we arrive, that’s less weight we need to launch from Earth and carry through space.Additive manufacturing is a way of printing three-dimensional (3D) components from a digital model. Thanks to our techies, we’re already testing this technology on the International Space Station.
