US Marine Corps Systems Command used a 3D printer to construct a prototype concrete barracks measuring 500 sq ft (46 sq m) in just 40 hours. The Marine Corps is now carrying out more research to see how the technology can be employed in the field and if the construction process can be refined further. (Photo/VCG)
