Inner Mongolia’s solar powered Dragonfly bridge may be the walkway of the future — but not soon enough. Filling the gaps is Eindhoven University of Technology, which 3D-printed the world’s first cycling bridge.
“One of the advantages of printing a bridge is that much less concrete is needed than in the conventional technique in which a mould is filled,” it said on [the university] website. “A printer deposits the concrete only where it is needed.”
The bridge is nothing grand in scale, but can reportedly withstand the weight of 40 trucks. While I don’t suppose you can cram that many vehicles onto a 26-foot bridge, the point is clear. The university’s partner company BAM Infra is hopeful that the bridge will inspire more efficient technology.
[BAM is] “searching for a newer, smarter approach to addressing infrastructure issues and making a significant contribution to improving the mobility and sustainability of our society.”
In the 3D-printing world, the Netherlands remains on top of cutting-edge resources.
