The Netherlands: the longest concrete cycle bridge in the world made in 3D printing

This is the longest concrete cycle bridge in the world, created using 3D printing technology.

Produced in collaboration with the Eindhoven University of Technology, the structure is 29 meters long, with round and sloping shapes. The building was printed layer by layer in the factory of the Saint Gobain Weber Beamix group, opened jointly with the manufacturer BAM, in Eindhoven.

This method only uses the concrete necessary for construction, which reduces the amount of raw material, thus reducing the environmental impact. This technique is also a source of economy, and conceptual freedom as explained by Professor Theo Salet of the University of Eindhoven.

“You can create any shape you want,” he emphasizes, without needing to “mass produce”. The 3D printer therefore allows personality each construction.

This concrete bridge, the longest made in 3D, spans a waterway in the city of Nijmegen in the Netherlands.
