3D 4D 5D printing Lifestyle
US Marines construct 3D-printed concrete barracks in U.S. Army Engineer Research and Development Center in Champaign, Illinois.
According to the Marine Corps Capt. Matthew Friedell, AM project officer in MCSC’s Operations and Programs/G-3,” the team used a design model on an old computer, concrete, and a 3D printer. The concrete was then put through the 3D printer. It took approximately 40 hours to complete the barracks hut. If there was a robot to do the mixing and pumping, the building could easily be created in one day. This capability would enable a great partnership with the local community because it is low cost, easy to use, and robotics could print the buildings.”
