In 2017, the world’s first prestressed 3D printed concrete bicycle bridge officially opened to cyclists. It was created by the Eindhoven University of Technology (TU/e) in collaboration with construction company BAM Infra, and was installed in the Dutch village of Gemert. The bridge was part of a research project that involved the development of a giant concrete 3D printer, and now the researchers involved have published a paper on the project, entitled “3D Printed Concrete Bridge.”
The bridge was designed to replace an existing structure over a small local canal. The structure is 3.5 meters wide and spans 6.5 meters. It consists of 3D printed elements that are rotated 90 degrees after printing, then pressed together by post-tensioned prestressing tendons.
