That’s quite a title, isn’t it? ‘3D printed steel bridge completed by welding robots’ sounds unlikely. But it’s true! Dutch 3D-printing firm MX3D has just announced the completion of an awesome looking stainless-steel bridge…
The 3D printed footbridge will cross Amsterdam's Oudezijds Achterburgwal canal.

The steel footbridge will cross Amsterdam’s Oudezijds Achterburgwal canal and was primarily built off-site using MX3D’s welding robots. These robots consist of a robotic welding arm that lays down a blob of molten metal, adding another blob on top once it’s hardened, repeating this process over and over until an entire metal section has been completed.

The completed bridge measures 12.5 metres in length, 6.3 metres in width and took a total of 6 months to print. It total, the bridge contains over 4,500kg of stainless steel as well as over 684 miles of wire.
A whole consortium of partners have collaborated to bring the 3D printed bridge to life.

MX3D have not been alone in this endeavour. A whole consortium of partners has come together to make the bridge a reality. From MX3D’s website: 

“The Bridge is designed by Joris Laarman Lab. Arup is the lead structural engineer. ArcelorMittal provides the metallurgical expertise. Autodesk assists with their knowledge on digital production tools. Heijmans is our construction expert. Lenovo supports us with computational hardware. ABB is the robotics specialist. Air Liquide & Oerlikon know everything about welding and lastly, Plymovent protects the air our employees’ breath whilst AMS and TU Delft do invaluable research. Gemeente Amsterdam is the first customer of our collaborative bridge building department.”

The bridge will now undergo a series of load tests to verify its structural integrity before it is installed over the canal in 2019.
