Contour Crafting: 3D House Printer

Behrokh Khoshnevis (USC Engineering) has been perfecting his contour crafter. The material used is a semi-liquid quick-setting, concrete-like compound. The system is able to make calls to onsite experts for insertion of plumbing and wiring as the construction effort proceeds. "The goal is to be able to completely construct a one-story, 2000-square foot home on site, in one day and without using human hands."
