        And even then, the filament needed at this scale will take another several years, and a few days for shipping.

        Also, it doesn’t do well in sunlight or high humidity for prolonged periods of time, so we’ll need maybe 20 to 30 years to work out a solution for that problem.

      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.

        So our proposal is we prefab a bunch of metal pieces and assemble them on-site?

          Well no, you put a conveyor belt in front of all the 3d printers, and when each part is done, it’s dumped onto the conveyor belt, which leads all the pieces to an AI powered robot arm which assembles the bridge.

          Yeah, I guess you could just run the conveyor belt and arm all the way to where the bridge needs to go.

          All problems can be reduced to Factorio.

        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.

It also mentions where parts are too complex to manufacture, they ask the AI to account for it and break it into components.

      No, you see, you just get every citizen to pay a little bit into the bridge, and then everyone can use it. Maybe we put some of that money aside and establish a group of people to care for the bridge, upkeep and whatnot. It wouldn’t be fair to just pick them arbitrarily, so we should probably hold some kind of vote. And, well, I guess the money will run out, so maybe we take a little more from everyone every year, just to keep it in good shape

        There are experimental construction printers that use concrete. Unreinforced, expensive specialty concrete, though, and it looks like they take more than a day to run on something big. And I assume sometimes fail like every other printer.

        I’d also like to see the pitch on GoFundMe. “Yeah, we actually do have tax collection powers, but we thought it’d be better if you specifically paid for this. Lines are open”

        Edit: Wait, are we talking about the bridge? Lol, so this is a kilometers-long bridge that has to float in a bay on a kilometers-long barge, and get lifted into place and fixed to an existing, differently constructed bridge somehow.

So it might be a hindrance to yourself to automatically throw out anything to do with “AI”, you might find something cool to use it for.
