We do still have open source hardware but that's the last line of defense against actions like this, not the first. They'll target distribution which will affect open source and proprietary hardware equally. You need to kill this sort of legislation in its crib.
You need both, because there really is no such thing as kill it in it's crib. The people that want this will continue to want it forever, and will continue to propose it forever. And eventually it works.
How would this situation be any different if BBL printers were open source?
The law doesn't care about licensing, there are just 2 groups of printers - those that follow the law and implement effective blocking technology and those that don't.
If BBL sells an open source printer that allows someone to trivially bypass proposed mandatory blocking technology, they'll be fined and held liable for any crimes that result from guns printed using their 3D printers.
So BBL, as open source as they might want to be, is not allowed to sell such a product.
I’m new to 3d printing. I saw bambu pushed a firmware update that bricked offline mode, so didn’t really consider them when shopping around.
I’m really liking my (better specs for less money) elegoo centauri. I compiled the slicer from source because there weren’t Linux binaries.
All problems solved. It even happily prints exotic stuff like TPU, which I guess bambu has been cracking down on for unclear reasons.
Maybe I don’t know what I’m missing, but I’ve had zero issues downloading files (even from bambu-centric websites) and running them through the slicer.
I can’t imagine wanting to use their cloud whatever thing, or it providing any value beyond the open source stacks.
Prusa had been moving towards proprietary licensing (if they release files at all) for a while now, due to their open source design files being used to undercut the original with cheaper clones.
I seriously doubt it's the undercutting that's the problem here. When they release a new model they can't keep up with demand anyway, they max out production capacity on legitimate orders.
I think, if anything, the problem is when people buy a cheap clone and blame Prusa when it fails.
We still have open source hardware in Voron. High performance and almost infinitely moddable. Pair it with the open source Klipper firmware and open source slicer OrcaSlicer and you're there.
I had the Kobra S1 with the ACE Pro and I couldn't get rid of the thing fast enough, probably the worst electronic device I have ever owned in my entire life. In 8 months with it I completed one multi-colour print, and that was only with ~30 filament changes - to be fair to Anycubic, their support has been excellent and they kept shipping me more and more parts to replace, none of which would solve the fundamental issue of the ACE being generally unfit for the job. In the end if was just a fancy £300 filament dryer, and I decided that you know what, even my Ender 5 was giving me fewer issues than this whole thing. I got an H2D with 2 AMSes and yes, they cost a fortune but they just work. I finished a 9 colour print with 800 filament changes the other day and it just worked fine, not a single problem.
I will always admit that maybe I was just unlucky with my S1 but both the printer and the ACE was horrendous experiences and I wouldn't recommend them to anyone based on my problems with them.
None I know did. If you do your research, all the hype around Bambu is paid. Influencers pushed it. Tech deep dives show it is sub standard. Posted on HN.
Prusa is king. High quality. Open source. EU made and engineered. Slicer is a market leader (Bambu's a fork of it).
Prusa may still be king if you're using printers commercially, running them hard 24/7 in a print farm, wanting to be sure your investment has a decent lifespan with readily-available spare parts and upgrade options.
But it's a premium brand now. For lighter use by hobbyists, Bambu is the clear winner on price/performance. The 'less open' downside is not a factor to most people, and the printers generally work so well out-of-the-box that repairability isn't as much of a concern as it was on printers of the past.
Personally I went from a Prusa MK3s to a Bambu P1P (after looking long+hard at Prusa options), and so far, no regrets. (Although I've kept the old Prusa as a 2nd printer and upgraded it to a MK3.5, but mostly just because I do enjoy a bit of tinkering with them)
If your goal is to buy the cheapest machine you can find in the world, chances are good everything you buy is going to come from China. That Prusa Mk3 you bought ages ago can be upgraded to the latest model, which means you have the option of turning that device into a lifetime machine, something ONLY Prusa offers.
Yes, the initial purchase price is higher, the lifetime price might not be.
Their QC and customer support has gradually been getting worse. Their printers are rarely competitive feature-wise. Several printer lines are quietly being retired - with bugs remaining open for years and new features only occasionally being backported from other printers. The open-source part is mostly abandoned due to cheaper third-party clones abusing it.
Don't get me wrong, I really like my Prusa printer, but in 2025 I'd have a really hard time justifying buying another one. The "Prusa premium" just doesn't seem to be worth it anymore.
Not criticizing your decision, but I went the opposite way, deciding that I was ok spending a certain extra amount initially in order to encourage a non-Chinese manufacturer. But I understand not everyone has this luxury.
I bought the Core One kit to understand better how the machine works, which reduced the price delta somewhat.
It remains to be seen over the long term which way is actually better financially, as Prusas have historically had long lives, while there is only limited data on the Bambu Lab side yet.
So far, I am quite happy with my decision. But competition is on. I am excited about the upcoming INDX system for the Core One: if it delivers on its promise, it will be fantastic!
I'm new to 3D printing, so grains of salt abound, but since I started in on the hobby this Christmas, I've purchased four 3D printers. 3 budget-but-highly-regarded kings to start, but they all gave me tons of trouble. The Elegoo Centauri Carbon I got for Christmas that sparked this mess is a budget knockoff of the Bambu X1C, but in the first 30 days of ownership, I experienced 2 hardware failures that (thanks to having to ship parts from Mainland China) have resulted in 16 days of downtime.
To deal with the downtime, I bought a stopgap Qidi Q2, but it had tons of problems -- problems which, according to the reviewers, have all been solved for. Ambiguous error messages. Poor English. Choices between "OK" and "Confirm", neither of which advanced the system. Mainboard errors. Extruder failures. Boot failures. Firmware upgrade failures. I experienced all of these within the first 3 hours of ownership, and filed for a return.
I was working on a project that needed a printer, and now despite having bought a bunch of printers, I didn't have any printers that could print. Looking around locally at what I could buy that day amounted to either a Bambu P2S or a Sovol SV08. I struggled here, because I would _much_ rather be the Sovol owner than the Bambu owner, but I needed a printer, not a project, and so I decided I'd try out the Bambu until I got done with what I needed it for, and then I'd return it.
But it turns out it was amazing. The others (admittedly, budget units) were loud and cantankerous, but the Bambu was only uncivilized for a few minutes of each print, and the rest of the time you barely noticed it running. The ecosystem is obviously great. Being able to monitor jobs or initiate prints from my phone is admittedly a novelty, but it's a nice one, and one that speaks to a consistency of integration. But the important part is that it just worked. There were printable upgrades available, I didn't need to print modular pieces to fix design flaws like the other units. I didn't need to move it further away to deal with the noise. I didn't need to investigate arcane error messages because none ever arose.
Now, I haven't owned a Prusa, so I'm not trying to compare them. I understand that Prusa hardware quality is amazing. I believe that. I'm also wildly interested in the community efforts to implement tool-changing with INDX and INBXX, and they're the kinds of projects that I want to tinker with. But if I'm to own a Prusa, or a Sovol, or a Voron, it'll have to be as my second printer (well technically third, because I still own the Elegoo because it's too cheap to bother trying to return) because most of the time I want to print things, not tinkering with the printer. But while the Prusa machines might be amazing, the Prusa XL is wildly expensive for 5 colors, and the Core One right now can't be bought with multi-color capabilities.
I'm not trying to argue against Prusa here, but the idea that only shills are into Bambu seems flatly wrong. I am ideologically opposed to how Bambu got to the market position they've reached, and for sure they've undoubtedly got a fair amount of shills in their employ but sadly, their products more than live up to the hype.
You are a "new" type of user for the 3d printing world.
In the last decade, most 3d printer users were hobbyists and liked to know the internals of the machine they were using.
That's why there are so many useless models of random gadgets on thingiverse. People didn't care about the output, more about the process.
With the arrival of bambu and the last Creality, the market has shifted to a plug and print model where more and more buy the printer as a tool to produce and output and they don't care about the internals or gcode.
They must be able to control their printers from their phone.
The people that started in 3d printing when they had to assemble the whole machine by hand are now sad to see their hobby replaced by something too easy, it feels like cheating.
"How come you don't know how to level the bed and measure the offset with a piece of paper? "
Just like senior dev are sad to see vibe coding replace "true development craft".

The missing the third ingredient which is passing rollback resistant legislation in its place that protects these freedoms.
That makes efforts far more durable.
Than it’s a matter of showing up in court to defend attacks against the law(s) that protect it.
In this way, we can have durable change, but it’s a high cost road. By design I am sure.
Nothing is forever. This whole thing rose in the first place because a novel technology was used to make weapons.
To give another example, the whole modern anti-vaxxer movement was started by a doctor to sell bogus tests.
Just print the code to do what ever is disallowed on a t-shirt, ala DVDCSS. Is that not a legitimate way around things like this?

Prusa is still kicking... if open source hardware is your priority.
Prusa had been moving towards proprietary licensing (if they release files at all) for a while now, due to their open source design files being used to undercut the original with cheaper clones.
I seriously doubt it's the undercutting that's the problem here. When they release a new model they can't keep up with demand anyway, they max out production capacity on legitimate orders.
I think, if anything, the problem is when people buy a cheap clone and blame Prusa when it fails.
This is why we can't have nice things
My Bambu printer is working great in LAN mode on a vlan with no internet access. Never even complains about it. I'm not concerned.
You can still make an open source printer with some extrusion and stepper motors, same as always.
We still have open source hardware in Voron. High performance and almost infinitely moddable. Pair it with the open source Klipper firmware and open source slicer OrcaSlicer and you're there.
This bill would effectively make prusa illegal, which is my main issue with it. I refuse to buy anything else if it is not open in the same way.
3D printer hardware is pretty simple. All the magic happens in software, and there's plenty of open-source options.
All the open source designs from 10 years ago still work, not like they went away.
Sovol open source hardware and software.
AnyCubic AMS is great

I have a friend that runs a small print farm and he had similar issues, but I didn't know if it was a one off. Thanks for sharing.

Prusa used to be king.

I'm a hobbyist and price, in the end, sold me on Bambu Labs.
(And I stayed once I saw the quality. Likely Prusa can match or exceed it, but not with what I was willing to lose from my wallet.)
Not criticizing your decision, but I went the opposite way, deciding that I was ok spending a certain extra amount initially in order to encourage a non-Chinese manufacturer. But I understand not everyone has this luxury.
