It's about 3D printing gun parts. Everyone knows this.

Except that their solution won't actually solve that at all, and will just be a huge, expensive violation of privacy. Also, there... isn't a solution. It's not like the law proposes a *method*, it just says "Identify gun parts from print files". This is not possible, even by "cloud based AI".

It depends entirely upon what is being printed. There are parts one wouldn't want 3D printed in the first place. And then there are parts which are obviously gun parts, like a lower receiver. The law is still unenforceable and useless.

That's what government is, a huge, expensive violation of privacy.

No, it was originally _intended_ to be about 3D printing gun parts. That's not the law they wrote, though. The law they wrote applies to ALL 3D printing, not just gun part 3D printing. I sympathize if you think they *meant well*, but they clearly screwed it up horribly, and need to start over.

I imagine most printer manufacturers will simply drop California if this passes. There is no way that 90% of the printer companies will be able to afford to make this impossible, make-believe "gun-detection" software (for gcode!!). It's not like California is providing it, just demanding it.

Furthermore, all of the software needed to operate a 3D printer is open-source. It is straightforward to build your own printer from parts. How will this bill impact that? Is the state of CA going to tell me that I can't build a printer because they think I might be a gun-printing criminal?

Again, I can do nearly nothing because I don't live in CA. I tried raising my own reps about this subject, but only got auto responses about protecting 2nd amendment rights. This may wind up a dead letter law due to the unfeasibility of this, but that's cold comfort when I can only sit and watch.

How on earth does trying to stop 3D printed guns trample your rights? On what planet should the 2nd amendment written by people who never imagined a car or dishwasher, much less semi-automatic weapons cover something like this? There's plenty of ways to get guns in America. Let's stop this one.
