SHIJIAZHUANG, July 22 (Xinhua) -- A university in north China set a new world record for the longest 3D-printed bridge on Tuesday.
With a length of 28.1 meters, the concrete bridge is modeled on Zhaozhou Bridge, a 1,400-year-old stone arch structure in China's Hebei Province.
The longest 3D-printed bridge was certified by Guinness World Records on Tuesday.
About half the size of the Zhaozhou Bridge, the 3D-printed structure was created by a research team led by Professor Ma Guowei of the Hebei University of Technology.
It has been installed on one of the university's campuses.
