Dutch officials have toasted the opening of what is being called the world’s first 3D-printed concrete bridge, which is primarily meant to be used by cyclists.
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 bridge is not very big, but it was rolled out by a printer, which makes it unique,” Theo Salet, from the Eindhoven University of Technology, told Dutch broadcaster NOS.
Work on printing the bridge, which has some 800 layers, took about three months after starting in June and it is made of reinforced, pre-stressed concrete, according to the university.
“One of the advantages of printing a bridge is that much less concrete is needed than in the conventional technique in which a mould is filled,” it said.
