Now You Can 3D Print A House [Video]
This construction technology fabricates large components out of concrete or other materials and could reduce energy use and emissions.
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:
