Crossing printed from 800 layers of concrete could take weight of 40 trucks, designers sayDutch 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. The Netherlands is among countries, with the United States and China, taking a lead in the cutting-edge technology of 3D printing, using computers and robotics to construct objects and structures from scratch. Last year a Dutch architect unveiled a unique 3D printer with which he hopes to construct an “endless loop” building. And a Dutch start-up called MX3D has begun printing a stainless steel bridge, of which a third is already completed. The aim is to finish printing by March and lay the bridge over an Amsterdam canal in June.
