Architectural firms are competing all over the world with their designs for 3D-printed companies, but Chinese company WinSun has moved past the design stage and actually produced such dwellings.
In March 2014, WinSun claimed to have printed 10 houses in 24 hours, using proprietary 3D printing technology. The builds consisted of an industrial waste and ground construction blend mixed with quick-drying cement and a special hardening agent. The total cost for all ten buildings was just £3,100, a minute fraction of the cost for a typical build. Now WinSun has produced a five-storey apartment building and a villa measuring 11,840 square feet, complete with interior and exterior decorations. The apartment complex is the world’s highest 3D printed building, and the villa is the first of its class to be created using this technology.
Both buildings are on display at Suzhou Industrial Park. The printer used to produce the homes is 500ft long, 32ft wide, and 21ft tall. A mixture of glass, steel, cement, and construction waste is sprayed on in layers until a thick wall results. The parts are fabricated in large pieces at WinSun's facility. Then the structure is assembled on-site, with steel reinforcements in order to meet building standards. WinSun, which has been in business for 12 years, holds 98 construction material patents and has a long history of innovation in 3D printing technology.
