Contour Crafting is a construction technology that potentially reduces energy use and emissions by using a rapid-prototype or 3-D printing process to fabricate large components. Comprised of robotic arms and extrusion nozzles, a computer-controlled gantry system moves the nozzle back and forth, squeezing out layers of concrete or other material to fabricate a form. The ultimate goal is to print a house in a day while drastically reducing material and energy consumption.
Professor Behrokh Khoshnevis has designed the giant robot that replaces construction workers with a nozzle on a gantry, this squirts out concrete and can quickly build a home according to a computer pattern. It is “basically scaling up 3D printing to the scale of building,” says Khoshnevis. The technology, known as Contour Crafting, could revolutionise the construction industry.
The revolutionary 3D concrete printer can build a 2,500-square-foot home layer by layer in a single day. The University of Southern California is testing the giant 3D printer that could be used to build a whole house in under 24 hours.
