What's the 3D printing bridges you know in the world?
-
I just published a blog titled "3D printed bridges from China", which mentioned two bridges: one is a 3D printed concrete bridge in Shanghai, and the other is a 'Zhaozhou Bridge' from Hebei University of Technology. Do you know other 3D printing bridges in the world? Let us discuss it together!
Let's learn more about them through this blog.
Do you think the 3D printed bridge is safe? let us discuss it together!

@Gracy thanks! Yes you're right, it is because of the overall geometry, more than the printing direction. It looks like an ancient stone arch bridge

@telephasic I learned from other articles that the structure is an unreinforced arched bridge that uses compression and gravity to hold its form. This compression-only structure allows the forces to travel to the footings, which are tied together on the ground. The dry-assembled construction is stable due to its geometry only.

requiring no mortar or steel reinforcement
Italy knows well what tragedies can happen when steel of concrete bridges fails... so if there is none, then this problem goes away
In other articles, it's explained that the strength without reinforcement comes from the direction of printing and layering. I certainly don't get it, but it will be interesting to follow!

how about this one, which was built about 4 years ago in Gemert-a town in Dutch.
It's made of concrete. It's not very big, but enough to pass through for the cyclists.
