NASA Sends 3D Printer To ISS To Test Printing In Low Gravity

NASA wants to test the possibility of using regolith (loose soil or rock) to 3D print structures right on the Moon. It has sent Redwire Regolith Printer (RRP) - a 3D printer to the International Space Station (ISS) to test 3D printing in low gravity. The study will show whether we can use regolith to build strong structures to withstand the extreme conditions on Moon and the Mars.
