Dezeen's Ben Hobson shares video coverage of research and development company MX3D's plan to use robots to construct the first fully-functional 3D-printed steel bridge over a canal in Amsterdam by 2017.

Co-led by Joris Laarman and Tim Geurtjens, the company has devised a system that combines an industrial robot usually used in car assembly lines with a welding machine and MX3D's software to print 3D metal.

The steel footbridge will span eight meters (approximately 10 feet). MX3D originally intended to print the bridge in situ, but had to abandon that plan over health and safety concerns. Laarman and his team will now reconstruct a section of the canal in their workshop to demonstrate that it could be done on site.
