First 3D-printed concrete bridge

The world’s first 3D-printed bridge has opened to cyclists in the village of Gemert in the Netherlands. It is 8m long, 3.5m wide and has a capacity of 5 tonnes. The reinforced, pre-stressed concrete bridge will be used by hundreds of cyclists per day and has been designed to last at least 30 years.

The bridge was printed in sections at the Eindhoven University of Technology and then assembled on site. Due to the fact that the printer can create any desired shape, it was said to offer greater flexibility of design than traditional formwork methods. It was also said to use less concrete, cutting both costs and carbon dioxide emissions.
