A private company located in eastern China has printed ten full-size houses using a huge 3D printer in the space of a day. The process utilizes quick-drying cement, but the creators are being careful not to reveal the secrets of the technology.

China’s WinSun company, used a system of four 10 meter wide by
6.6 meter high printers with multi-directional sprays to create
the houses. Cement and construction waste was used to build the
walls layer-by-layer, state news agency Xinhua reported.

“To obtain natural stone, we have to employ miners, dig up
blocks of stone and saw them into pieces. This badly damages the
environment,” stated Ma Yihe, the inventor of the printers.
Yihe has been designing 3D printers for 12 years and believes his
process to be both environmentally friendly and cost-effective.

“But with the 3D printing, we recycle mine tailings into
usable materials. And we can print buildings with any digital
design our customers bring us. It’s fast and cheap,” Yihe
said.
