The world’s first 3D-printed steel bridge has opened to the public in Amsterdam. This project began back in 2017 when robotic 3D-metal printers were used to manufacture and assemble large sections of the bridge, but the final placement of the steel structure had to be postponed for years since the canal walls needed to be restored. Engineers hope this bridge will open a world of possibilities for architects, engineers, and designers. Read more for a video and additional information.
Multi-axis robots were used to heat the steel to 2,732°F before constructing the bridge layer by layer. This nearly 40-foot structure is composed of almost 10,000 pounds. During its inauguration, Dutch Queen Maxima pressed a green button to activate a robotic arm equipped with a pair of scissors to cut a ribbon and open the bridge for pedestrians as well as cyclists.
- Self-developed Silent Motherboard: The Ender-3 V2 built-in self-developed silent motherboard, which has stronger anti-interference, faster and more stable motion performance, silent printing and low decibel operation.
- UL Certified MeanWell Power Supply: Equipped with MeanWell power supply, produced by the listed company with mature technology, meeting all the needs of fast heating and long-time printing. Moreover, the power supply is concealed in the machine, making it much safer.
- Effortless Filament Feed-in: Ender-3 V2 adds a rotary knob on the extruder, making loading and feeding filament process much easier; Brand new operation UI system and 4.3" smart color screen greatly improve user experience.
- Resume Printing Function: Can resume printing from the last recorded extruder position after suffering unexpected power outages, saving your time and reducing waste.
- Carborundum Glass Platform: Enable the hotbed heat up quicker and prints adhere better without the warping. Ultra smoothness even on the first layer.
For over four years we have been working from the micrometre scale, studying the printed microstructure up to the metre scale, with load testing on the completed bridge. This challenging work has been carried out in our testing laboratories at Imperial, and during the construction process on site in Amsterdam and Enschede, the Netherlands, on the actual printed bridge,” said Professor Leroy Gardner, Department of Civil and Environmental Engineering.
