3D printing will always amaze us. In Spain, the IAAC (Advanced Architecture Institute of Catalonia) has put in place the construction of the first pedestrian bridge entirely printed in 3D. The latter was built in the city of Alcobendas, near Madrid.
The bridge is 12 meters long and 1.75 meters wide. This is the first real construction of this type made in the world. The ultimate goal is to democratize 3D construction using optimized and recycled materials.
