California’s New Bill Requires DOJ-Approved 3D Printers That Report on Themselves (blog.adafruit.com)

California’s new bill requires DOJ-approved 3D printers that report on themselves targeting general-purpose machines.

Assembly Member Bauer-Kahan introduced AB-2047, the “California Firearm Printing Prevention Act,” on February 17th. The bill would ban the sale or transfer of any 3D printer in California unless it appears on a state-maintained roster of approved makes and models… certified by the Department of Justice as equipped with “firearm blocking technology.” Manufacturers would need to submit attestations for every make and model. The DOJ would publish a list. If your printer isn’t on the list by March 1, 2029, it can’t be sold. In addition, knowingly disabling or circumventing the blocking software is a misdemeanor.

Oh boy, what's a good not too expensive 3d printer to buy right now, preferably all FOSS? It hasn't been on my short term shopping list but I figure if I'm ever likely to want one, better get it now. I remember the original RepRap. I think modern stuff is a lot better, but might have more closed source software.

Prusa or Qidi. Avoid Bambu.

You can still get an Ender 3 (essentially the end result of RepRap). Every vendor has their own.

That said? If you buy a printer in 2025 (let alone 2026) and it does not have an integrated enclosure, you are opening yourself up to a world of hurt. The price difference isn't that much anymore and even just having a box to hold the waste heat in solves like 90% of print problems.

Bambu are, above and beyond, the best bang for your buck. They ALSO are ahead of the curve on locking things down to support only their networked slicers. Which... is a huge concern with stuff like this.

Personally? I love the Qidi printers. I have a Q1 something or another and convinced a friend to get a different model. They use a semi-open fork of Klipper so you can theoretically make something work when it is abandoned. Which is good because the various CoreXY printers are no longer all based on the same standard so part kits aren't (easily) interchangeable. And, of course, you can use Orcaslicer or whatever else you want.

Keep in mind that is all FDM. For Resin (SLA?), the ship has already sailed and people are genuinely happy to run slicers with literal fucking ads in them. Assuming the vendor doesn't lock them out of even that garbage.
