South African Students Develop Mobile, Self-replicating, 3D Printer

3D printing in outer space has become quite the fad as of late. This is mostly due to the fact that NASA and Made in Space recently sent a zero-g 3D printer to the ISS for testing in micro-gravity conditions. On top of this, the European Space Agency has been talking a lot lately about the possibilities of 3D printing large structures on soils foreign to Earth. With this, comes the idea of a 3D printed moon base which features radiation shielding.
