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.
