WinSun 盈创建筑科技（上海）有限公司
Shanghai building-materials firm that printed 10 houses in 24 hours (2014), a Suzhou apartment block (2015) and Dubai's Office of the Future (2016).
WinSun is the brand of Yingchuang Building Technique (Shanghai) Co., Ltd., a Shanghai company that became widely known in the mid-2010s for printing building components out of cement-based mixes that include recycled construction and industrial waste. Chinese business press describes the company as a high-tech enterprise founded in 2002 that develops and produces new construction materials; its chairman, Ma Yihe, has been quoted as having worked on 3D printers for more than ten years by 2015.
Projects reported in the press:
- March 2014: WinSun said it had printed the shells of ten small houses in 24 hours.
- January 2015: at Suzhou Industrial Park in Jiangsu, the company unveiled a five-storey apartment block (Chinese media reported six storeys and about 15 m in height) and an 1,100 m2 villa with decorative elements, which RIBA Journal reported cost around USD 161,000 to build. At the time these were described as the tallest 3D-printed buildings in the world.
- March 2016: two printed Chinese-style courtyard houses of 80 m2 and 130 m2, designed by Ma Yihe, at a reported cost of RMB 400,000.
- May 2016: the main structure of the Office of the Future in the Dubai International Financial Centre, a single-storey building of about 250 m2. Printing took 17 days and on-site assembly two days. The project was announced in July 2015 by WinSun Global, the company's international joint venture, together with architects Gensler, structural engineers Thornton Tomasetti and consultants Syska Hennessy, and served as temporary offices for the Museum of the Future team.
Process and materials. RIBA Journal described the printer used for the Suzhou buildings as an array 6.6 m high, 10 m wide and 40 m long. Components are printed from a mix of recycled construction or industrial waste such as glass and mine tailings with cement and special hardeners. WinSun claimed the method saves 30 to 60 percent of construction waste, shortens production time by 50 to 70 percent and cuts labour costs by 50 to 80 percent. Wall sections and other elements are printed in a factory and assembled on site rather than printed in place; Behrokh Khoshnevis, the University of Southern California professor behind Contour Crafting, publicly questioned the company's claims on this point and accused it of using his ideas.
Current status. All verified project information dates from 2014 to 2016. The company's domains (winsun3d.com, yhbm.com) still respond but sit behind a human-verification wall, so no current product line, printer model or contact details could be confirmed for this profile. The company is included in RobotToday's construction landscape under construction 3D printing.
