It's a bridge, Michael, how long could it take? Two days?

a day

My brother in plastic, a 3d printer will take a day to print a silly figurine, let alone a whole ass bridge made of metal and concrete.

A level 11 wizard could simply cast wall of iron, fabricate, teleport, and telekinesis. It could be done in one day at no cost to the tax payer.

"those are the facts" says biggest moron you have ever met

not pushing crypto for the fundraising?

i was having depression thoughts about being dumb today but this post made me feel a lot better

"free to taxpayers"

So who's donating to the gofundme then?

Theres no way he actually believes this

Techbros think that a country that can't even maintain a metal and concrete bridge also will have the infrastructure to 3D print that same bridge and then assemble it in two days, and also somehow not be publicly funded

I think techbros like this should just renounce the west and live in China. They already have Public works projects that get built near instantaneously. Except it's not with AI and drones or whatever, it's the power of a coherent communist party

Rome was 3D-printed in a day. Checkmate, structural engineers!

Unironically China is building dams that usually take 10 years to build in 2 years by essentially 3d printing the dam layer by layer using automated driverless cement trucks as extruders.

But in 2 days? Man some people are just..

No you can't just give the 3d printer the plans for a bridge.

using AI

FOR WHAT HOW WOULD A LARGE LANGUAGE MODEL SPEED UP A 3d PRINTER

Again, this is what genius speak sounds like to hot couch guys.

Did they ever get those 3D printed houses off the ground, or are they still just a concept?

edit: okay so the number worldwide is less than 200 as of a couple years ago, so it's still very rare and in the "figuring out if it's worth it" phase. 3D printers have a looooong way to go before they're able to even be considered for something this large, and then they'll still have a long way to go before they're competitive with already-existing steel manufacturing.

And what advantage would 3D printing bring to bridgemaking anyway? Steel is very recyclable, so material efficiency isn't really a large benefit. Most of the process in terms of time is moving the pieces into position and assembling them, while making steel beams and cables are both very fast and mature processes, so that's not good either.

And what the fuck is the AI going to do, generate a blueprint that's just a bunch of noise?

I would suggest that instead of the bridge they use my hog but I'm afraid it's not small enough to fit

the funniest part to me is the "just lift it into place" part

Superman will do it pro bono

If I was building a bridge, I would simply do it in a day.

Why not build it in the metaverse, then sell the bridge to the highest bidder which would then provide funding for a bridge in meatspace?

This is like retrofuturism but for the 2010s

Step 1: Build the world's largest steel and concrete 3D printer.

Step 2: Invent BridgeGPT to control the printer

Step 3: Build a barge to place it on.

Step 4: Work out quality control and logistics.

Step 5: Get random people to sign up to pay for it.

This is going to be so fucking easy!

I know that you think the 3d printer doesn't exist that could print this but that's where your wrong. See we'll use AI to design smaller printers that can print this big one. And AI to design smaller printers than those to print the medium sized ones. Just keep doing this until you get to the size where enough printers exist and they can just work together to print everything in a day.

It'll take me a day to read the wiki about the properties of sintered metal so I'll do that while you sinter an entire bridge. It'll be fine.

large

Are we sure it's not a bit? Even a moron could google What is the biggest thing to ever be 3D printed?

Ninja edit

This google result five years old but other results seemed like a lie.

In 2019, the Center printed 3Dirigo and earned two Guinness World Records — the world's largest 3D printed boat and the world's largest 3D printed object. The 25-foot, 5,000-pound boat was printed in 72 hours.

laugh all you want but America will soon have the world's first thermoplastic bridge DECADES before the Chinese do. This is why we are are the most innovative country in the world and always will be.

These people have never built anything in their lives

perfection

We should just like, build a Dyson Sphere

what about giving each girder a token on the blockchain

I don't believe these are even techbros anymore.

These guys all seem like unserious hangers-on to what they think techbros are like. I really think they're either children, or adults who keep the bong cleaner in their bong when they hit it.

They like the aesthetics of tech so they repeat a lot of buzzwords they hear but I think their extent of tech usage is like, installing a theme on Opera GX or buying a 3d printer kit that they put together incorrectly and just tell everyone they'll get around to fixing it.

These people have always existed in other forms. They're like guys who do car repair with drywall screws

Why don't they simply put down some Mario Kart boost pads to launch cars across the bay? Easier than replacing an entire bridge and cheaper to maintain as well!

Is this elon's alt account?

hey, i'm a person who owns a 3D printer and knows a quite a bit about them

1. this guy has maybe heard of 3d printing and maybe has read an article, that's about it
2. there is absolutely no fucking way to make a printer for this - it would have to be steel+cement multi material, and you can already forget about ever doing that. the printers for steel and cement are completely and inherently different, and I don't think they even make steel printers larger than roughly the size that would fit in a corner of a workshop/lab, only cement printers are made for large industrial tasks like housebuilding. not to mention how difficult and costly steel printing is
3. even if such a god printer did hypothetical, the bridge would be so ungodly expensive to fabricate and would take so long and there would be so many places for shit to go completely wrong that it would be entirely pointless and dangerous to use 3d printing for the job, you would just be better off building the fucking thing.

maybe in the future it might be possible but in the present this guy has directly connected his asshole to his mouth
