12-25-2017: WinSun created the world’s first 3D-printed concrete bus stop

Bus stop was installed in Fengjing, a town in the Jinshan District of Shanghai

In December 2017, the world’s first 3D-printed concrete bus stop was installed in Fengjing, a town in the Jinshan District of Shanghai, China. The bus stop was located along one of the local roads.

The structure featured a closed rectangular frame design measuring 5.1 meters in length, 1.5 meters in width, and 2.7 meters in height. The project was executed by WinSun (Yingchuang Building Technique (Shanghai) Co., Ltd.), a company specializing in 3D printing in construction. The bus stop was made using recycled industrial and mining waste materials, highlighting its environmental benefits. The printing process reduced construction waste and material usage by 60%, while cutting labor costs by 50% to 80%.

The bus stop was printed at WinSun's facilities and then transported to the installation site, where assembly took less than an hour. This method significantly accelerated the construction process and minimized disruptions to local traffic compared to traditional building techniques. The company claimed that the 3D-printed bus stop was five times stronger than conventional structures built using traditional methods.

WinSun Construction Technologies, founded in 2003 in Shanghai, specializes in 3D printing technology for construction. Over the years, it has completed a variety of projects, including the printing of single-family homes, villas, and public buildings. Among its most notable achievements are the printing of 10 homes in Shanghai, a villa in Suzhou, and 19 government offices in Dubai.
