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.

printers can literally be built with dumb electronics, some pieces of metal and an arduino.

juat saying.

Funny enough, guns can be made from a handful of hardware store parts.

[–] umbrella@lemmy.ml 8 points 23 hours ago (1 children)

there it is. yes, and you guys have a constitutional right to bear arms, with an infinity of them already in circulation.

[–] rumba@lemmy.zip 1 points 23 hours ago (3 children)

That didn't work well for that doctor that was murdered by ICE.

[–] oyenyaaow@lemmy.zip 6 points 21 hours ago (1 children)

hardware store parts didn't work out so well for Shinzo Abe too.

[–] UnderpantsWeevil@lemmy.world 2 points 18 hours ago

Not personally. But Sanae Takaichi was Abe's ideological successor. Now she's right back in the PM with an enormous majority.

You can doohickey the man, but you can't doohickey the movement.

Very frustrating to see people confuse Gun Ownership with Being Bulletproof.

As though you're going to quick draw on the entire LASD, at which point they'll all just tip their hats and proclaim "this person has constitutional rights, we will leave peacefully and not bother you again".

But he didn't draw on them, it was in it's holster, they removed it from his holster, then murdered him

But he didn’t draw on them

Because he was rushing to help one of his neighbors recover from tear gas. Which is what an EMT is trained to do.

they removed it from his holster, then murdered him

As they were trained to do

that's because usians have the illusion they live in a democracy and that weapons are a right instead of a duty.

the fact they can have a weapon doesn't mean the regime will take lightly to dissidents, just that they can in fact have them for now. fascists certainly have them, that's for sure.

and historical figures or whatever said this was gonna happen and shit.

My main printer up until last month was powered by an Arduino Mega. Like not even an "Arduino-compatible ATMEGA 2560-based 3D printer control board" an Arduino Mega, with the infinity +- logo. Reprap style.

[–] umbrella@lemmy.ml 4 points 1 day ago* (last edited 1 day ago) (1 children)

my current printer is powered by an arduino mega, and it's staying that way while i can. the best appliances are the ones you can control and replace yourself if you need to. 😉

all parts you can find at a hardware store + some 3d printed pieces. repraps and foss printers are the best period.

I am the owner of a brand new Prusa MK4S. A lot of its components aren't open source, but it's an i3, I can keep it running, and I can hit its wifi module with a hammer if I want to.

[–] RagingRobot@lemmy.world 7 points 1 day ago (1 children)

Are you suggesting ghost printers? Lol

[–] umbrella@lemmy.ml 7 points 1 day ago (1 children)

i'm suggesting regular, non-enshitified printers.

[–] trackball_fetish@lemmy.wtf 4 points 1 day ago (1 children)

Until they make that illegal.

[–] umbrella@lemmy.ml 6 points 1 day ago

oh, i would bet on it.

i wanna see them try to enforce it though.

[–] deathbird@mander.xyz 6 points 1 day ago

Well the answer is banning Arduinos, obviously 🧐
