Unfortunately it’ll take 10 years to build the printer.

And is that huge 3D printer in the room with us now?

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.

I can only assume they’re trying to talk about concrete 3D printing, but oh boy is that not ready for anything which needs strength.

How weak are we talking? All I’ve seen is the press releases.

Just cut up the model into a million individual 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!
Zacryon@feddit.de 6 months ago
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?
As opposed to our current method where we carve bridges out of a big block of metal?
Zacryon@feddit.de 6 months ago
Hahahaha absolutely. :D The difference is, that they come from a 3D printer and that’s cool.

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.

Where’s the train? Why is there no train in the solution?
CatOnTheChainWax@lemmy.today 6 months ago
Seriously, how we make bridges now with giant CNC machines is so inefficient! And all these people saying we should print lots of blocks to put together are totally forgetting about Legos, we all just need to donate our old Legos to Baltimore and let kids from anywhere come volunteer to build it. Free bridge and free child labour! Everyone wins

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.

casting the parts
Steel beams get extruded and rolled, or… 3D printed with a large, custom shaped, hot end! 🤯
Skua@kbin.social 6 months ago
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
CanadaPlus@lemmy.sdf.org 6 months ago
Maybe, we could just print off rectangular prism-shaped modules, small enough 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
