I mean i can make a plastic bridge too, doesn't mean it will last.
You can't just "print" a steel bridge and expect it to not snap the second day it open to public, it ain't sci-fi.
You probably could make a 3rd printer capable of printing the steel components for a bridge. If you pour enough money and time down the drain, there's no reason why you couldn't have some robots handling the scaffolding and "3D printing" the concrete too. It would be severalÂą orders of magnitude slower and more expensive than using the normal processes, but hey why build 10000 bridges when you can build just one that tech bros can masturbate to.
Âą this "several" is breaking the world record of heavy lifting
Just have the AI design a smaller 3D printer to print the larger one.
Its printers all the way down
There's a 3D printed bridge in Amsterdam: https://www.dezeen.com/2021/07/19/mx3d-3d-printed-bridge-stainless-steel-amsterdam/
A 12m stainless steel pedestrian bridge that took 6 years to make and was subsequently “strengthened” to meet safety requirements. Not quite the same thing.
