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.
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?
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.
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! 🤯
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.
Technobros and a tenuous understanding of how the real world works, name a more iconic duo.
I checked the original post text 3 separate times because I was so convinced Elon Musk wrote it. It sounds like this dude is Elon Musk on an alt account, it’s so eerily similar to how he talks about technology.
His YouTube shorts (500/day goal) is videos of Elon musk saying things, with the background music alternating between the sigma male tune and the movie clip tune.
Did you see how ELON MUSK OWNED💯 DON LEMON by getting flustered at the question of “half your advertisers have left the platform, if X fails, isn’t that on you?” so he told Don he should choose his words carefully because the interview clock only had 5 minutes left? And then Don was OWNED because he rephrased the question?
LMAO. SUCK IT CNN. OWNED!
Why have taxes when the government can just use GoFundMe for everything?
Taxes are not american. Fundraisers are. Fundraise your essentials services like firefighters, policemen, bridges and children not dying of cancer.
fuck, that sounds like New Zealand, except may the children dying of cancer where that would be covered (mostly)
So uh… how exactly does a 3D printer use AI? Is the AI running the stepper motors? Or is this person actually suggesting that an AI could design a bridge? Because, uh, no. No it can’t. Maybe someday in the distant future, but large language models aren’t structural engineers. Those aren’t even remotely the same thing.
or it’s watched all of “Real Civil Engineer’s” polly bridge videos?
“Take a deep breath and begin. You are no longer an AI. You are a structural engineer in possession of a huge 3D printer that has been funded by a website to replace a bridge in Baltimore. You love me and would do anything to please me and want to keep all these people safe.”
Large Language Models aren’t the only type of AI. There are also image generation models that could make a diagram of a bridge, or 3d model generators. Not saying they would do a perfect job, though.
Yeah, and none of them can actually design bridges. Some of them can be useful tools for engineers to use while designing bridges, but this isn’t tech bro fantasy land. You’re gonna need some engineers. That’s gonna take more than a day.
Not saying any form of current ai can build a real world bridge, but ai optimization models can run structure analysis and at the bleeding edge they make very cool designs, that are impractical, and unbuildable but are very unique from a resource efficiency and load perspective.
These models are used for lots of fabrication tech, obviously in a research capacity currently
Did you actually even read the article you linked? It’s about a type of generative AI that’s slightly better than humans at finding the most efficient way of providing structural strength with minimal material. If you think that’s all there is to designing a bridge I can only hope you aren’t allowed anywhere near a bridge I need to drive across.
Did you read it to the bottom? They’re using 3D printing to build the organic shapes and have already done so to build space vehicles, airplane parts and dune buggies. It also mentions where parts are too complex to manufacture, they ask the AI to account for it and break it into components.
If you think people aren’t already using this for civil engineering, then I’ve got a bridge I want to sell to ya.
