The ultimate goal for Contour Crafting is to print a house in a day.
Contour Crafting is a form of 3D printing that uses robotic arms and nozzles to squeeze out layers of concrete or other materials, moving back and forth over a set path in order to fabricate a large component. It is a construction technology that has great potential for low-cost, customized buildings that are quicker to make and can therefore reduce energy use and emissions.
One of the men behind the process, Behrokh Khoshnevis from the Center for Rapid Automated Fabrication Technologies (CRAFT) told treehugger:
We will be able to build curves and domes as easily as straight walls. Your shoes, clothes and car are already made automatically, but your house is built by hand and it doesn’t make sense… Compared to a conventional house, the speed of construction will be increased 200-fold and the building costs will be reduced to a fifth of what they are today.
