The first 3D printed bridge has just opened which could start a wave of new outdoor 3D printed structures. Experts are seeing this as a way to bridge the gap between sustainability and civil engineering.

The bridge is 12 meters long and printed on micro-refined concrete. Its made of 8 different parts, each made of concrete powder and micro-reinforced with thermoplastic polypropylene. A new computational design was used to maximize structure and performance while reducing cost and materials used.

This new bridge is located in Madrid, Spain.
