Even the phrase "world-changing" might be a bit too strong.
It's enabled some acceleration of product prototyping and it has democratized hardware design a little bit. Some little companies are building some buildings using 3D printing techniques.
Speaking as someone who owns and uses a 3D printer daily, I think the biggest impact it's had is that it's a fun hobby, which doesn't strike me as "world-changing."
It might not lead to singularity but for people who work in academia, in terms of setting and marking assignments and lecture notes, for good or bad AI has had an enormous impact.
You might argue that LLMs have simply exposed some systematic defects instead of improving anything, but the impact is there. Dozens of lecturing workflows that were pretty standard 2 years ago are no longer viable. This includes the entirety of online and remote education which ironically dozens of universities started investing in after Covid, right around when chatgpt launched. To put this impact in context, we are talking about the tertiary and secondary sector globally.

I don't get this. Either you do graded home assignments which the person takes without any examiner, which you could always cheat on, or you do live exams and then people can't rely on AI . LLMs make it easier to cheat, but it's not a categorical difference.
I feel like my experience of university (90% of the classes had in-person exams, some had home projects for a portion of the final marks) is fundamentally different from what other people experienced and this is very confusing for me.
This is an easy quip to make, but it's also pretty wrong. 3D printing has been a massive breakthrough in many industries and fundamentally changed the status quo. Aerospace is a good example, much of what SpaceX and other younger upstarts in the space are doing would not be feasible without 3D printed parts. Nozzles, combustion chambers, turbopumps etc are all parts that are often printed.
I honestly don’t, although maybe that hype cycle was before my time.
But this seems an unfair comparison. For one, I think 3D printing made me better, not worse, at engineering (back when mechanical engineering was my jam), as it allowed me to prototype and make mistakes faster and cheaper. While it hasn’t replaced all manufacturing (or even come close), it plays an important role in design without atrophying the skills of the user.
Honestly, both are pretty good for prototyping. I haven't found AI helpful with big picture stuff (design) or nuts and bolts stuff (large refactorings), but it's good at some tedium that I definitely know how to do but guess that AI can type it in faster than I can. Similarly, given enough time I could probably manufacture my designs on a mill/lathe but there is something to be said for just letting the printer do it when plastic is good enough (100% of my projects; but obviously I select projects where 3D printing is going to work). Very similar technologies and there are productivity gains to be had. Did the world change because of either? Not really.
I find AI has the potential to do that (in my software development job): But so far I'm only using it occasionally, probably not as often as you used 3D printing.
Well yeah, the singularity isn't close by any measure.
But 3D printing and AI are on totally different trajectories.
I haven't heard of Mattel saying, "we're going to see in what places we can replace standard molding with 3d printing". It's never been considered a real replacement, but rather potentially a useful way to make PoCs, prototypes and mockups.
Yep, I think this further illustrates OP's point—hobbyists building low-stakes projects get enormous benefits from LLM tooling even while professionals working on high-stakes projects find that there are lots of places where they still need something else.
3d printing will slowly edge its way into more manufacturing. The humble stepping motor really is eating the world. 3dp is one manifestation of it!
Back to AI though.
I just checked the customer support page of a hyped AI app generator and its what you expect: "doesn't work on complex project" "wastes all my tokens" and "how to get a refund"
These things are over promising and a future miracle is required to justify valuations. Maybe the miracle will come maybe not.
I'm not sure why you continued using words when you summed up 3D printing with those four words. In the time it takes to print 1 object, you could have molded thousands of them. 3D printing has done a lot for manufacturing in terms of prototyping and making the first thing while improving flexibility for iterations. Using them for mass production is just not a sane concept.
> Remember when 3d printing was going to replace all manufacturing? Anybody?
Sure, but I'd argue the AIs are the new injection molding (as mentioned downthread) with the current batch being the equivalent of Bakelite.
Plus, who seriously said 3d printers were going to churn out Barbies by the millions? What I remember is people claiming they would be a viable source of one-off home production for whatever.
for small run manufacturing, 3d printing is absolutely killing it. the major limitation of 3d printing is that it will never be able to crank out thousands of parts per hour the way injection molding can and thats ok. creating an injection molded part requires a huge up front investment. if you're doing small runs of a part, 3d printing more than makes up for the slow marginal time with skipping the up front costs alltogether.
No, because 3D printing was never going to replace all manufacturing. Anyone who said that didn't even have a basic understanding of manufacturing, and I don't recall any serious claims like that.
3D printing has definitely replaced some manufacturing, and it has had a huge effect on product design.
These anti-AI articles are getting more tedious than the vibe coding articles.
