The bridge printed by Amsterdam scale-up MX3D has been opened today by Her Majesty Queen Máxima using a robot. The first 3D printed steel bridge in the world has been placed on the Oudezijds Achterburgwal in Amsterdam. This pedestrian bridge with smart sensors (thanks to a.o. University of Twente) will replace the old bridge, which is under external restoration, for the next two years. The bridge, an award-winning design by Joris Laarman Lab, is the result of a unique collaboration between MX3D, software company Autodesk, chief engineer Arup, steel giant ArcelorMittal, the City of Amsterdam and University of Twente, among others.
