In Shanghai, houses not built, they're printed

A Chinese company recently built 10 full-sized houses using a giant printer.

The detached, one-story houses now standing in the Shanghai Hi-Tech Industrial Park, in the city's Qingpu district, look like ordinary buildings. But they were "printed out" in less than a day with "contour crafting", commonly known as 3-D printing technology.

Four huge printers measuring 32 meters long, 10 meters wide and 6.6 meters tall were used to make the houses, which were built layer by layer.
