Solar printer makes lunar bricks from moon dust

Chinese scientists developed a solar-powered 3D printer that turns lunar soil into construction bricks, potentially enabling future lunar cities. The device uses concentrated sunlight to melt regolith into dense, robust bricks for shelters, roads, and platforms, reducing the need for Earth-based materials. These bricks will serve as protective shells for pressurized habitats, shielding them from radiation and meteorites, with testing planned on China's space station.
