Bryant Jordan: “Add to guns and prosthetic hands something much bigger and heavier forming from the nozzle of a 3D printer — buildings “printed” out of concrete. Partially funded by the Office of Naval Research and the National Science Foundation Countour Crafting is trying to develop 3D printed buildings using concrete. Company founder Behrokh Khoshnevis is a professor and director of Manufacturing Engineering Graduate Program at the University of Southern California. Concrete printers would be able to build a 2,500-square-foot building within a single day, according to Khoshnevis. For the military, that means soldiers deploying to a remote location with little or no infrastructure could be operating out of permanent structures pretty soon after a combat engineer unit arrived with printers and material aboard a C-17.”
