At first glance, Dr. Behrokh Khoshnevis’ Contour Crafting (CC) seems both fascinating and unreal – a fabrication machine that has the potential to construct entire structures in a single run. Supported by the National Science Foundation and the Office of Naval Research, CC’s combination of conventional robotics and “age-old tools” creates a layered fabrication process where large-scale parts can be fabricated at remarkable speeds. On his blog, Khoshnevis, a professor in the USC Viterbi School of Engineering, explains that the system is a scale-up of the rapid prototyping machines now widely used in industry to “print out” three-dimensional objects designed with CAD/CAM software, usually by building up successive layers of plastic. ”Instead of plastic, Contour Crafting will use concrete,” explained Khoshnevis.
