3D-printed bridge at the Lichtwiese


Scientists from the “AM Bridge 2019” research project at TU Darmstadt are revolutionizing steel construction. Their goal: a 3D-printed steel bridge over flowing water. The demonstration project on the site of the Department of Civil and Environmental Engineering at Lichtwiese has now been completed. The plan: Welding a complete bridge over water.

But the people in Darmstadt wanted more: Instead of printing individual components, the robots welded the bridge as a whole, on site and over water. The idea was realized with the help of the “CMT Cycle Step” welding process. What's special about it is that welding spots can be produced in any size and precisely reproduced.
