A 3D-printed bridge is being built using reinforced concrete

3D printing is a massive category that covers everything from small, DIY, plastic projects to metal meant to be used in Boeing’s 787 airplane. Yet another usage has come to light, courtesy of the Eindhoven University of Technology in the Netherlands. Researchers there have started manufacturing parts for a 3D-print reinforced concrete meant for a cycling bridge. When the construction is complete, it’ll apparently be the first bridge to use 3D-printed, reinforced concrete (but not the first 3D printed bridge using other materials — or even concrete itself. (The image above shows a 3D-printed concrete test done at the Nanyang Technological University in Singapore; the one below comes from the Eindhoven University of Technology.)
