Robots to 3D print gravity-defying steel bridge in mid-air over Amsterdam canal

An ornate steel bridge will be built in mid-air over a canal in Amsterdam in 2015 using 3D printing and robots, and surprisingly it will not require support structures. Dutch 3D printing R&D startup MX3D has invented a 3D printing technique whereby multi-axis industrial robots are able to print strong, complex structures anywhere without needing a print bed.”
