World’s First 3D Printed Steel Bridge

The first 3D printed steel bridge was constructed across the Oudezijds Achterburgwal canal in Amsterdam, which if not mentioned, would look like a regular bridge unit. This 3D bridge is a product of additive manufacturing, which unlike usual 3D printing projects, steel is used for printing. In usual 3D printing proprietary inks or a starting material is used.

World’s First 3D Printed Steel Bridge

The construction of bridge was initiated in 2015 and completed by the collaborative efforts of MX3D, a Dutch startup focusing on 3D metal printing, researchers at Imperial College London, and The Alan Turing Institute.

World’s First 3D Printed Steel Bridge Installation

Features

• The 3D printed steel bridge was constructed using multi-axis robots in order to heat the steel to 2,732 degree F.
• It was constructed layer by layer
• The bridge has a span of 12 m and weighs around 10000 pounds of stainless steel
• The bridge is equipped with multiple sensors that enables data collection of strain and vibration of people using it under different weather conditions.
• The data help researchers to understand the behavior of the bridge over a time period.
• The sensors helps to identify the areas that will require maintenance, modifications, which can be used for the construction of large projects.
• The bridge was opened for pedestrians and cyclists.
