Navy Helps Fund 3D Printing of Buildings

( The Office of Naval Research and the National Science Foundation are partially funding Countour Crafting to develop 3D printed buildings using concrete. Concrete printers would be able to build a 2,500-square-foot building within a single day. That means soldiers deploying to a remote location with little to 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.
Building via Contour Crafting’s 3D printer would work just like any computer assisted manufacturing program. But instead of a robotic tap and die machine turning out parts according to a program, it would be an oversized printer following programmed schematics to lay down, layer by layer, a building, including outside and interior walls, spaces for doors and windows and all electrical, plumbing and air-conditioning conduits.
