Print A 2,500 Square Foot House In 20 Hours
We have seen immense progressions in 3-D printing. We have even seen oversized wrenches printed that measure 1.2 meters in length. Now, we can print an entire 2,500 sqft house in 20 hours. In the TED Talk video below, Behrokh Khoshnevis, a professor of Industrial & Systems Engineering at the University of Southern California (USC), shows automated building, using 3D printers to build an full house in 20 hours.
In fabricating we use a process called CAD/CAM (computer-aided design / computer-aided manufacturing). 3D models are designed on a computer and so manufactured using CNC Machines or 3D printers. The blueprint is manufactured into a physical object automatically, with instruction from 3D computer model to physical object without human interface. Automatic construction basically scales up this process. The size of the 3D printer is big enough to manufacture walls by depositing concrete based material layer upon layer to build a wall.
