2018: Creation of the first-ever steel bridge printed on the 3D-printer

The Dutch company MX3D specializing in robotics for 3D - printing, completed the work on the first-ever steel bridge made using an additive technology, reports the Dezeen edition. From October 20 to October 28, 2018 the 12-meter pedestrian bridge can be seen at the Dutch Design Week exhibition in the Dutch city of Eindhoven then it will be set over Audezeyds Forburgval channel (Oudezijds Voorburgwal) in Amsterdam in the well-known red light district

The project of the bridge was offered in 2015. Construction from molten steel a layer behind a layer was printed by six-coordinate robots. In April, 2018 the bridge span was made, and also the flooring so construction is completely ready is complete now. On the course of implementation of the ambitious project construction was finished to increase its durability on a case of possible collision with boats.

The initial design underwent significant changes in connection with difficulties of technical character. Construction, easy, similar to a tree, was located on four support. The problem was that if the boat crashes into one of support, all bridge could sustain serious damage. Therefore absolutely new model considering all factors from features of material to requirements of the local legislation was developed — told about construction of the bridge in MX3D.[1]

Besides, it was necessary to refuse the idea of production of construction on site. The limited budget and lack of permission from the city authorities which considered that similar works can be dangerous did not allow to implement an idea.

Operation of the bridge it is going to monitor using the sensors registering data on load of construction, its tension and vibration. Also information on quantity and speed of the pedestrians crossing the bridge, integrity of construction and the environment will gather.
