Check out this lengthy vid: it shows how one day you may just call-in giant robots to print out a new home based on a CAD model. Research into the concrete-jet printer is being carried out by USC, and their technology can already build up complex concrete structures using technology that's half-CNC machine and half inkjet-like. They've just got funding from Caterpillar to further the research. Amazing stuff, especially when the team says it should be eventually be able to put together a 2,000-square-foot, two storey home in just a day, with all the wiring and plumbing automatically inserted too. Even NASA is interested, as this may be a good solution for building Moonbases. (The Register via Bot Junkie)
