3D Printed Reinforced Concrete Cycling Bridge

The world’s first 3D printed reinforced concrete bridge starts to take shape in the Netherlands.

Researchers at the Eindhoven University of Technology in the Netherlands, starts printing the world’s first 3D printed reinforced, pre-stressed concrete bridge.

The cycle bridge will be part of a new section of ring road around Gemert in which the BAM Infra construction company is using innovative techniques.

One of the advantages of printing a bridge is that much less concrete is needed than in the conventional technique in which a mold is filled. By contrast, a printer deposits only the concrete where it is needed. This has benefits since in the production of cement a lot of CO2 is released and much less of this is needed for printed concrete. Another benefit lies in freedom of form: the printer can make any desired shape, and no wooden molding frames are needed.
