The Technical University in Eindhoven, working with construction company BAM, started 3D printing a bicycle bridge this weekend. The bridge is the first of its kind in the world and is printed with pre-stressed and reinforced concrete, according to NOS.

TU Eindhoven professor Theo Salet called the process very exciting and stressful. "Stressful because the work you do is being put into practice for the first time. It must be safe." He said. "A lot has been done to investigate how the material behaves and how it will behave if it forms a real construction. So this step, from the laboratory to something that is used in practice, is very beautiful, but also stressful."
