Additive manufacturing has just proved once again that it has a bright future ahead of it. In fact, the first 3D-printed concrete pedestrian bridge in the world was created a few weeks ago in Alcobendas, Spain, which is not far from Madrid.
 
The bridge, which allows passage over a stream, was modelled by the Institute of Advanced Architecture of Catalonia and printed by Acciona.
Made of concrete, it is 12 metres long and 1.75 metres wide.
