3D-printed bridge on campus sets world record

SHIJIAZHUANG－A university in North China recently set a new world record for the longest 3D-printed bridge.

With a length of 28.1 meters, the concrete bridge is modeled on Zhaozhou Bridge, a 1,400-year-old stone arch structure in North China's Hebei province.

The bridge was certified by Guinness World Records in late July.

About half the size of the Zhaozhou Bridge, the 3D-printed structure was created by a research team led by Ma Guowei, a professor at the Hebei University of Technology.

It has been installed on one of the university's campuses.

The Zhaozhou Bridge, also known as Anji Bridge, stands over the Xiaohe River in Zhaoxian county, Hebei province. It was built during the Sui Dynasty (581-618).
