World's longest 3D-printed concrete bridge opens in China
The world's longest 3D-printed concrete pedestrian bridge, which is 26.3 metre-long and 3.6-metre-wide, opened in China's Shanghai last week. The bridge is made out of 44 hollowed-out 3D printed concrete blocks which were printed by two robotic arms in a span of 19 days. The newly-opened bridge has a technology that supplies data which also includes vibrating wire stress sensors.
