An innovative startup plans to create a 3D printed steel footbridge in Amsterdam.

MX3D specialises in "3D printing outside the box". In other words, they print highly complex objects in metals and resin, using multi-axis robots instead of a conventional box-shaped printer. The robots literally draw forms in mid-air, without the need for support structures.

This latest project aims to show the world the potential of this manufacturing technique to create beautiful, functional objects on a grand scale. The bridge is designed to be strong and durable enough to support cyclists and pedestrians for decades.

It will be constructed over one of Amsterdam’s old canals. The team views this as a fitting metaphor: the bridge will serve to "connect" the history of the city with cutting-edge future technology.

In September, the City of Amsterdam plans to announce the exact location of the bridge and open a visitors’ centre where the public can track the robots' progress.

The design and execution of the project will involve collaboration between MX3D, construction company Heijmans, software company AutoDesk, the Joris Laarman Lab, ABB Robotics and the Amsterdam City Council.
