NASAs plans for 3D printing with robots.
NASA wants to 3D print lunar base too, with giant spider robots
“Last month, the European Space Agency (ESA) was teaming up with its industrial partner renowned architects Foster + Partners to test the feasibility of 3D printing using lunar soil and to build a lunar base.
It seems that NASA has also got a similar idea: using existing resources on the moon to build those structures. Space architects Tomas Rousek, Katarina Eriksson and Dr. Ondrej Doule have unveiled their vision for a lunar module which shows the potential of 3D printing technology from NASA.” ~ 3ders.org
