Setting up a future lunar base could be made much simpler by using a 3D printer to build it from local materials. Industrial partners including renowned architects Foster+Partners have joined with ESA to test the feasibility of 3D printing using lunar soil. The base is first unfolded from a tubular module that can be easily transported by space rocket. An inflatable dome then extends from one end of this cylinder to provide a support structure for construction. Layers of regolith are then built up over the dome by a robot-operated 3D printer (right) to create a protective shell.
