WELL, THIS IS THE 21ST CENTURY, YOU KNOW: 3D Printing of a lunar base using lunar soil will print buildings at 3.5 meters per hour. “Setting up a 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. This is a case where 3d printing would win out over regular manufacturing. Most of the material is lunar dirt but with added magnesium oxide and a binding ink. This greatly reduces the weight of the material to be brought to the moon. There has been previous work on using carbon nanotubes and epoxy to make lunar concrete.”
