What are the odds of this passing successfully? A grim day for 3D printing if so.

If it becomes law, then other US states and countries will try to copy it as well.

Doesn't NY already have something similar?

Are 3D-printed guns even remotely reliable, or is it just a moral panic? A brass tube and a pin is probably less likely to fail than 3d printed materials.

People normally don't make guns that are entirely 3d printed. Homemade guns often get the parts exposed to highest stresses commercially.

Fwiw, when I paid attention to my local police department's released body cam vids, maybe around 1/3 of the guns they showed as evidence were polymer80s (edit: which I mistakenly assumed were 3d printed, but it turns out they aren't so feel free to disregard that fun fact)

Here's a series of models, which of these is a gun part? https://imgur.com/a/p3UtJqW Money anti-counterfeiting is trivial, it's just 5 dots arranged in a specific pattern. Deciding what is a gun part is impossible, even for an expert human.

I just fundamentally don't understand the idea that nobody's allowed to restrict firearms manufacturing unless they can solve complex riddles about the nature of parts. I understand that you perceive this to be a deep and interesting point, but to me it seems enragingly obtuse. Let's start with blacklisting DefCAD and iterate from there, what's wrong with that? Like, it's true that refrigerators don't maintain a comp…

How long until people get police showing up at their door because they tried to print something harmless but gun-shaped (like a light gun for retro games, or Nerf-style toys) and were flagged by the AI 'firearm detector'?

Polymer80 aren't 3d printed. They were injected molded as non-receivers and then the customer has to subtract some extra materials.

Polymer80 is defunct but still sold under a slightly different modified mold that someone mysterious somewhere owns and is selling through some other companies("76%" instead of 80%)

The actual bill in question: https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml... It seems more precise to say that 3D printers sold/transferred in California would need built-in anti-firearm-printing controls? I don't see how this directly bans students/teachers/businesses from owning 3d printers, which is what the title seems to say.

It does not. The gun lobby routinely lies about California regulations to try and get their way. They're on year 13 of boycotting the California handgun market, for example; new handgun models in the state are required to adopt microstamping technology, but firearms manufacturers are ideologically opposed to this technology, so they falsely claim that it doesn't exist.

I'm getting a lot of refusals these days from multiple LLMs on multiple fronts for silly stuff, a lot more than I had for a while. If this is where things are really going, I think open weight models have a big future.

And China wins the AI race

If that becomes current law I don’t want to ever hear about Europe being over-regulated compared to the US…

There are several snarky knee-jerk reactions in the comments here, but state assemblies pass things all the time that ultimately fail to pass or get vetoed. Now the public will debate it, contact their state senators to give their opinions...it's all part of the process.

California constantly passes all kinds of weird, pointless, and burdensome gun laws. There are so many of them, and they're so poorly written, that no lawyer in the state who can confidently tell you what's legal and what isn't until a court chimes in. There's no meaningful process around any of that.

The only thing that's different about this one is that it mentions a technology geeks care about. But I doubt that's enough. As another commenter noted, you can no longer hide behind "we have no technology to distinguish between guns and non-guns". We have AI that's supposedly PhD-level and will soon automate all jobs. Looking at STL files sounds like a job.

That's actually one of my fears about LLMs: they make thought policing cheap. There are profound privacy and cost barriers to having a Facebook employee review all your private messages. There are no such barriers to having a robot watch all your IMs in real time.
