The European Space Agency (ESA) has proven that its project to 3D-print a base on the Moon is possible. In a latest video the agency shows how 3D-printing robots may be used to build the base using lunar material.

The ESA started investigation of the lunar base possibility in 2013, working alongside its industrial and architectural partners. The creation of the reliable semi-spherical structures on the surface of the moon could be fulfilled within the next 40 years, and 90 percent of the materials needed would be derived from the moon itself.
