The world’s first 3D-printed bridge

In October 2017, the first 3D-printed bridge of prestressed and reinforced concrete was opened in Gemert. The bridge was printed at the Eindhoven University of Technology, in collaboration with BAM infra. The bicycle bridge is part of a larger road construction project at Gemert.

800 printed layers

The bicycle bridge is the first real civil engineering project of 3D-printed concrete. The bridge is 8 meters long and 3.5 meters wide. The bridge consists of about 800 printed layers and is assembled on site. To make sure the bridge was safe, the builders put a load of five tons on the bridge. The bridge is designed to service for thirty years.

Environmentally conscious

3D printing is important for the future and the environment. Less material is needed and less waste is wasted. With this method, there is less CO2 emissions as well. It is also often cheaper and faster than the traditional way of building and fewer preparations need to be made.
