The Technical University in Eindhoven in the Netherlands has started 3D printing an 8 m bicycle bridge in Gemert, near the city of Eindhoven. The university is carrying out the first-of-its-kind concrete 3D printing project with the Royal BAM Group, a Dutch construction company founded in 1869. If there’s anywhere in the world that needs a 3D printed bridge (or two), it’s the Netherlands.
