Professor Behrokh Khoshnevis from the University of Southern California, has come up with a concept that allows houses to be built faster and with lower labor costs. The Contour Crafting is essentially a large 3D printer that can produce a custom house ready in 20 hours. The technology is able to add painted walls, floor tiles, plumbing, and electrical wiring,
Khoshnevis recently gave a TED Talk at Ojai, California, explaining that the large-scale printer is especially valuable for homes destroyed in natural disasters and need to be rebuilt quickly. The technology can also be adapted to create luxury homes and large buildings. Watch the video as Khoshnevis explains the process and technology behind Contour Crafting.
