First 3D-Printed composite bridge

Royal HaskoningDHV, CEAD and DSM have reportedly developed the first lightweight 3D-printed pedestrian bridge made of fibre-reinforced composite material. This was announced by the parties involved on 3 September. For the time being, it is a prototype. The bridge consists of glass fibre reinforced thermoplastic PET (Arnite). During the 3D printing process, continuous fiberglass is added to the polymer. According to Royal HaskoningDHV, the combination of these materials ensures high strength with extreme versatility and durability. In addition, by including sensors in the design, a digital twin of the bridge is created, as it were, with which maintenance can be predicted and optimized, safety guaranteed and the life of the bridges extended. It can also contain new functionalities such as monitoring of vital environmental aspects and the decision-making process for maintenance can be improved.
