And is that huge 3D printer in the room with us now?
shakily points to an Etch-a-Sketch
Unfortunately it'll take 10 years to build the printer.
It is right below your feet
Just cut up the model into a million smaller parts and post them on thingiverse so everyone on that site that already has a 3d printer can print one out and mail it to baltimore. EZ
You better start believing in huge 3D printers
…you’re in one!
To be fair, you don't need a very huge 3D printer for that, if you divide it into a lot of smaller parts which can be assembled later.
Idk, if we can already print steel though and whether we can make it structually sufficiently stable.
I find it difficult to believe that breaking down steel to be 3d printed into large structures for a bridge is faster or more energy efficient than casting the parts instead.
Steel beams get extruded and rolled, or... 3D printed with a large custom-shaped hot end! 🤯

We can indeed print steel with direct metal laser sintering. I think that the object needs heat treatment afterwards, though to be fair it is almost ten years since I properly read up on it and things have probably advanced since then
Maybe, we could just print off rectangular prism-shaped modules, around the right size to fit in a hand, and then assemble them on site. We could even make them out of ordinary clay and fire them for strength. I wonder why nobody has thought of that. /s
3D printing has it's place, but more conventional methods have theirs too. If you are counting on a lot of human labour anyway you might as well not reinvent the wheel.
OP said use AI, not humans... /s
