#62I can't help but wonder how could, Bambulabs or the Chinese government, actually mine that data? In my mind, 3D models fail into two categories: artistic and utilitarian, though there's a continuum between those two. With the artistic side, the Chinese government could find itself in possession of tons and tons of Western miniatures. With the utilitarian side, they will find themselves in possession of lots and lots…

I think you are underestimating how many companies use 3D printing for prototyping. It's not just hobbyists printing miniatures. To give an example, I had RSI and use a high-end, expensive ergonomic keyboard. The company that makes these keyboards does not go immediately from design idea to an expensive mold. There are many design iterations and prototypes and they are all 3D prints. The same is probably true for air…
I think you're overestimate the value of these prototypes. The print itself is either a plastic render of the final product without any value, or it's a shell without any actual useful parts/machinery. If we imagine we're talking about the 1% of 1% of 1% which could end up as useful IP stuff, but which might be very hard/impossible to find/understand/do anything with it, for which cases don't use bambu.
You’re making the assumption that customer product prototypes are the only prototypes produced by 3D printers.
There’s plenty of other more valuable things that are prototyped using 3D printers, such as high end commercial machines, or components that go into those machines.
I suspect that getting hold of STLs from US defence manufacturers would be extremely valuable. Why bother trying to capture a copy of your enemies technology, when they’ll happy just send you all the prototype STLs. Even if it’s not defence, don’t you think access to prototype components from EUV machines from ASML would be crazy valuable to Chinese companies trying to close the gap between Chinese and Western chip fabrication technologies?

Software Freedom Conservancy is at least fighting back. https://sfconservancy.org/news/2026/may/18/bambu-studio-3d-p...
I am annoyed that they just claim that "reverse engineering" will take care of this, instead of really trying to fight back legally. This is a social problem, and reverse engineering can only help up to a point.
A legal battle is expensive and time consuming. For example they have been fighting one with Visio since 2021[0]. It’s going to court this year.
I’m not sure how well tested AGPL has been tested in court, but assuming it has, the SFC has the right to reverse engineer anything covered by the license. That will help people sooner than trying to get a court to make a decision.

Terms of service are not legally binding, copyright licenses are legally binding.
There is no precedent for AGPL enforcement against Chinese companies, so no, not really. Feel free to post a docket if you disagree though. Also there are plenty of cases for ToS violations look up Facebook vs BrandTotal, or more recently Epic vs Apple. In the same way no one here cares about archive.org paywall circumvention, non techie end users don't care about open source violations (why should they). Look at the…

#66With DeepSeek making their price rebates permanent we now have some data what China values data access at.
Western providers of the open weight models are 3 times or more as expensive as DeepSeek itself right now.
Of course the data access for the Chinese is not the only part valued in there, but I am pretty sure it is one.

#68Cannot agree more with Josef on how dangerous this is for our intellectual property; Of course there laws and mechanisms in China for the government to obtain any information retained by their companies under any possible justification, but the US does so, and thanks to the Cloud Act they can simply decide to do the same with any of the big players sitting in their territory (even to servers located out of their terr…
Your cloud act is making American cloud vendors lose customers in droves

You don't have to login to X or download the app (if you're on mobile). X won't let you see the replies otherwise. I also prefer that the layout is denser and you can see more content at once, at least on my phone.

Not everything that a Chinese company does is for nefarious reason or under the hidden agenda of the Chinese government. The reality is much more mundane: many Chinese companies do not understand the expectations around open source. There isn’t anything really equivalent in China. The closest mindset is that things that are available to use, are available to take. The notion of copyright -while not inexistent- is not…

Except that Bambu is not a small player in the game, and they made threats of using the DMCA which shows they are fully aware of "western" IP law and the nature of licenses, Open or otherwise.
