3-D printing technology changes house building

3-D printing technology is revolutionizing the way houses are built.

A stand-alone villa and a full-sized, six-story building that had been created by huge printers with "contour crafting", commonly known as 3-D printing technology, were recently shown at the Suzhou industrial park in Jiangsu province.

"3-D technology has integrated the traditional processes of building a house, which helps improve work efficiency, shorten the time scale and save costs," said Ma Yihe, who developed the printers used to build the houses.
