Comment on '3d-printing a screw' is a way to describe how AI integration is stupid most of the time

Um. You do know that people already print screws using materials like metal and nylon, which are what a lot of screws are already made out of. Just saying. 😊
Anyone suggesting Ford or Toyota start 3d printing their fastening hardware in-house should have the head checked.
That’s the point of the analogy. You can do this, but in most cases, you probably shouldn’t, and you will get better results for less time and money with the traditional method.
I just watched a thing on the expensive mustang gtd. They do use 3d printed titanium for some pieces, but they didn’t go into much detail.
Point I want to make though, it always starts on the expensive things, then advances as the tech gets better. If Ford is using it for basically hand built mustangs, it’s only a matter of time before we see it on normal production vehicles.
Idk about that. For some custom built things it might be a better manufacturing method than setting up a production line to cast the piece or forge or whatever. But outside of some really weird screws there are always going to be extremely competitively priced screws of almost every imaginable type. It’s hard to imagine you’re gonna beat that with 3d printing, given you can just buy the screws you need for not much more per pound than the metal its made from.
Who suggested major manufacturers 3d print their parts? That’s not what the analogy said at all. But hey, make your own shit up if that makes you feel smug and superior.
I think you’ve completely missed the point.
We produce screws at industrial quantities, out of various materials, lengths, heads, pitches, etc etc etc.
The industrial scaling of this production results in screws being really really inexpensive. So inexpensive that depending on quantity you’re looking at, the finished screws are no more expensive to you than the raw materials.
Yeah you can print a screw. The question is why?. It will be more expensive per unit, more labour intensive, of worse quality, and will do wear and tear to equipment you own. It’s a lose/lose/lose/lose.
The one exception is that it is some mystical bespoke screw. And even then, it is likely that there are traditional methods which would better achieve that end (buy some screws that you can develop a process to modify in order to meet your needs)
It’s a good analogy. Yes you CAN 3D print a screw. It doesn’t mean it’s appropriate or even economical to include them in your products. Yes you CAN vibe code something. It doesn’t mean it’s appropriate or even economical to include them in your products.
Aren’t eggs produced at industrial scales from chickens, who super-abundantly exist?
How is that working out?
In no universe does the economics of a $1 egg make sense, yet here certain countries are. Did you know you can have chickens in your backyard, and they’ll turn bugs and cheap feed into eggs?
The less you can offload production to central untrusted parties, the better. When you manufacture something yourself, you get to know all the properties instead of trusting that some people elsewhere (whose primary motivation is money) still considered your interests by making a quality product.
So when you say “we,” what does “we” mean exactly? It is rhetorical.
Additionally, you get consistent reproducibility without reliance on large scale logistical networks. There are many other reasons I can think of off the top of my head beyond this.
If we lived in a more cooperative world, with ironclad democratically owned logistics networks and manufacturing, centralized manufacturing would make sense in the way you say. But the reality is, we do not live in that world, and more and more, we are all increasingly feeling what that means.
I’d just like to comment that keeping your own chickens is not economical unless you are basically willing to convert your yard into a chicken farm and slaughter your chickens once they stop laying eggs after a couple years, and even then its gonna take you a while to recoup (ha) the cost off the chicken coop, feed, etc, not to mention the time it takes to take care of them. What you’re really paying for with the cost of $1 (or really, 50 cents or less for most people) an egg is the convenience of eggs in the quantity you want them, with guaranteed quality, whenever you want them. Same with buying screws from the hardware store.
Economies of scale exist, regardless if you like them or not. You have a die for a 2nm processor in your garage? Gonna take a garden trowel into the backyard and dig till you hit a vein of rare earth metals?
Rugged individualism is a romantic concept, but not well supported by human history. If you make everything by your own hand, the sum total of your output will really just barely be enough to keep you fed.
I can’t even really fathom this response to the idea that you shouldn’t 3D print screws. It’s like I kicked your dog or something.
If you want to make your own screws, go ahead, make your own screws, but even then the analogy still holds well: don’t 3D print them. Use a tap and die set.
Tools exist to make screws and a 3D printer is the most expensive, slowest, and will produce inferior screws compared even to the existing make-screws-at-home options. On top of that, if, I don’t know, if you’re in an apocalyptic post-socoiety breakdown where logistical networks collapse… And you’re subsisting on backyard chickens… Still think you want the tap and die set for the purposes of screw production. No electricity, no files to get corrupted as your computer rusts out, essentially no maintenance required. Easier to transport.
Just because a technology is new and flexible doesn’t mean it’s automatically the best way to do all of the things it can "technically* do.
I will process wood vinegar and corn starch into PET plastic to 3D print expendable stuff eith, thanks
I mean, random bespoke dimensions show up all the time in 3D printing, including adding screwing features.
It doesn’t remove the point about standard screws being far better made the classic way, but screwing shows up plenty often anyways!
One thing it’s good for is that if you have the screw/nut on the bed with the part, you can scale both equally and the screw/nut will work with the part still, even if the threading is no longer a standard pitch/size. For a one-off or prototype that’s fine, but if you’re going to mass produce, it’s better to fix it in CAD to a standard size and use manufactured fasteners.
Yep. If it’s meant for mass production, that’s solid advice for ALL components, not just screws. Anything that’s not a standard part will need to be adapted to other production techniques anyways, as 3D printing is extremely inefficient for mass production.

They do, its just not economical for energy and time, when you are dealing with something generic. Good for broken one offs
