Recently, the world's first steel bridge constructed by 3D printing technology was installed on the Amsterdam canal and officially opened to the public. The bridge is 12.2 meters long and 6.3 meters wide. Four robots work together to weld the metal layers together with standard welding wire and gas. A total of 6000 kg of stainless steel was used. It took 6 months to print out the entire bridge. .

It is reported that this bridge demonstrates the low loss and high efficiency of 3D printing technology. Its shape is unique, and the appearance of flowing lines is completed by 3D printing technology, which perfectly combines automation technology with welding.
