And finally… World’s first 3D printed bridge opens

The first 3D-printed bridge in the world has been unveiled in a park in Madrid.

The pedestrian crossing was first installed in the urban park of Castilla La Mancha in Spain’s capital city in December last year and now it is ready to be walked on.

The bridge, which is 12 metres long and 1.75 metres wide, was printed in micro-reinforced concrete at the Institute for Advanced Architecture of Catalonia in what was to date, the first example of printing being applied in the field of civil engineering.

The bridge is also environmentally friendly because the production process that used ‘parametric design’, allowed the team to optimise the distribution of materials and minimize the amount of waste.

They were able to recycle the raw material during manufacture and dispose of by-product only where completely necessary.
