The world’s longest 3D printed pedestrian bridge has been completed in Shanghai.
The record-breaking bridge was designed by Professor Xu Weiguo from the Tsinghua University (School of Architecture). He says he was inspired by the ancient Zhaozhou Bridge built during the Sui Dynasty (581-618 CE).
The bridge measures about 86 feet long and 12 feet wide. It took 450 hours for two robotic arms to print the concrete components. Seems like a lot of work, but the bridge cost two-thirds of what a traditionally-built bridge would cost.
During the opening of the bridge, 100 people were invited to walk across the bridge for the first time.
Coincidentally, another, smaller 3D printed bridge was unveiled the same weekend in Shanghai.
