A team led by professor Xu Weiguo at the Tsinghua University School of Architecture in Beijing has 3D-printed a 26.3-metre-long concrete bridge, which they claim is the world's longest.
The 3.6-metre-wide pedestrian bridge, which spans a canal in Shanghai's Baoshan District, was installed earlier this year. It was designed by Tsinghua University School of Architecture's Zoina Land Joint Research Center for Digital Architecture (JCDA), and built by Shanghai Wisdom Bay Investment Management Company.
"The completion of the pedestrian bridge marks a gratifying step for this technology from research and development to practical engineering applications," said JCDA.
"At the same time, it marks the entry of China's 3D concrete printing and construction technology into the world's advanced level."
