The first 3D -printed concrete bridge has been opened in 3D in the Netherlands . There was applause as officials wearing hard hats rode over the bridge on their bikes at the inauguration in the southeastern town of Gemert on Tuesday. The cycle bridge, which is only eight metres long, consists of 3D layers of 3D -printed, pre-stressed and reinforced concrete, and took last June to build since work began last June . The project was carried out by the Eindhoven University of Technology and the BAM Infra construction company, and the structure was successfully tested for a maximum load of only eight metres . The about 800 -printing technique enabled the use of less concrete than would have been required by traditional mould methods.
