3D printing technologies are becoming more and more popular. Of course not, when they guarantee a reduction in production costs and time and a high level of durability. People have been excited about 3D houses for a while now, and now we've got the biggest printed concrete bridge.
The largest 3D-printed concrete bridge in the world, intended for pedestrians, stands in Chinese Shanghai. The team behind the project JCDA under the guidance of a professor Xu Weiguo with Tsinghua University School of Architecture, a research center for digital architecture Zoina Land and an investment company Shanghai Wisdom Bay.
3D-printed bridge in length 26.3 meters, and in width 3.6 meters. For example, the design team used jmeala the ancient bridge of Anji, which stands in the city Zhaoxian and is considered the oldest still standing bridge in China. It was built between 595 and 605.
The creators first built a scale model of the bridge before printing it 1:4, which proved that the structure withstands all efforts and is safe to use. Two hybrid systems were used to print concrete components 3D printer and robotic hands, they needed 450 hours.
The bridge, which is characterized by high printing efficiency and precise design, is equipped with a special control systems. This one includes load sensors, which collect data on the force acting on the bridge. In this way, the team will find out how the material will fight with external influences over time.
