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.

Someone more eloquent than I am needs to craft a compelling argument that this violates the 2nd amendment.

[–] Naia@lemmy.blahaj.zone 2 points 4 minutes ago (1 children)

It also violates the first and fourth. And it does nothing about gun violence.

It's also impossible to actually implement and is no more than one more privacy violation to add to the pile.

[–] AngryCommieKender@lemmy.world 1 points 35 seconds ago

This is what I'm talking about. We are stating to get to a cojent argument that I can call my representatives with and bitch them out, politely.

Am a Californian by choice.

[–] lechekaflan@lemmy.world 1 points 9 minutes ago

Silly woman who proposed that bill, if passed the law will only create a black market for 3D printers.

[–] SaveTheTuaHawk@lemmy.ca 4 points 49 minutes ago

Wow...they got us, no way we can print an STL from a USB stick.

[–] CetaceanNeeded@lemmy.world 1 points 18 minutes ago

This is going to make life hard for hobbyists not criminals.

[–] SaveTheTuaHawk@lemmy.ca 2 points 53 minutes ago

This is so fucking dumb. Anyone can Smith a gun at any hardware store.

[–] MonkderVierte@lemmy.zip 3 points 3 hours ago* (last edited 3 hours ago)

Btw, this doesn't include 3D-printer parts?

[–] phutatorius@lemmy.zip 8 points 5 hours ago* (last edited 5 hours ago)

Bauer-Kahan is a Democrat, if you wonder.

If the bill is passed, I'd be surprised if Newsom didn't sign it.

[–] rushmonke@ttrpg.network 9 points 5 hours ago

This is all politics is, convincing morons to vote for puppets of the ruling class.

[–] EtherWhack@lemmy.world 10 points 6 hours ago (2 children)

I imagine it wouldn't really be too difficult to design parts in a way that they would be completely inconspicuous until trimmed and assembled

I bet the code is cracked within the hour of every update from now until eternity. It's like the shit physical locks we put on everything. Nothing but a display of safety.

[–] nutsack@lemmy.dbzer0.com 7 points 4 hours ago

or a 3D printer that doesn't call the FBI

[–] Bluefruit@lemmy.world 32 points 9 hours ago (2 children)

Wow a great bill to stop people from making weapons. Y'all gonna ban pipes and steel ball bearings next?

The fuck is our country coming to man.

[–] SaveTheTuaHawk@lemmy.ca 1 points 52 minutes ago (1 children)

I would like some regulation of middle aged men with beards 3D printing excessive numbers of Magic the Gathering characters.

[–] Burninator05@lemmy.world 1 points 6 minutes ago

Hold up. I'm not sure if we want to crash the filament market.

[–] douglasg14b@lemmy.world 28 points 6 hours ago

Here's the thing. This isn't about banning weapons. It's about controlling access to IPs and preventing right to repair.

A forcibly Internet connected online. Only 3D printer that has to first check a public database to see if it's allowed to print the thing you just sent is most definitely going to be used to block you from printing parts to fix your appliances or devices.

And definitely going to be used to provide copyright protection and blocking to IPS of large corporations and companies.

[–] SabinStargem@lemmy.today 28 points 10 hours ago (1 children)

Even if this bill was in good faith, I wouldn't want it: I believe that the USA is headed into a civil war, and I want the good guys to have the ability to manufacture stuff if they need to. Be it guns or tractor parts, having flexible logistics will be invaluable. Not just for military use, but also for civilians who don't have access to official parts.

In any case, the implementation of universal healthcare and UBI would be much more helpful for quelling violence. People who can have access to mental healthcare and with enough prosperity, are much less likely to become deranged enough to murder people. Measures like this, often exist to keep the peasants from being able to rise up against their overlords.

This thing is a product of malicious greed, not for the sake of good.

[–] elucubra@sopuli.xyz 3 points 7 hours ago

Mental health care is a challenge even in universal health countries. MH is very time intensive.

[–] tal@lemmy.today 23 points 11 hours ago (2 children)

I guess that'd make open-source firmware illegal.

[–] random_character_a@lemmy.world 1 points 46 minutes ago* (last edited 45 minutes ago)

If you haven't noticed open source is under attack. Hammer has been rising for a while.

edit: meaning FOSS

[–] ikidd@lemmy.world 9 points 10 hours ago

That's just a happy by-product for them.

[–] Someonelol@lemmy.dbzer0.com 38 points 13 hours ago (1 children)

Just messaged my assembly member asking to vote against it. I suggest those who live in the state to do the same thing too.

[–] rushmonke@ttrpg.network 2 points 5 hours ago

Messaging your representatives is a waste of time and only exists to make you feel good about yourself.

The only way to fix problems like this is to vote for better reps, but we're too stupid to do that so the problem doesn't get solved.

[–] MatSeFi@lemmy.liebeleu.de 63 points 15 hours ago (8 children)

Sorry, I’m just a guy from overseas trying to understand why, in a country where 1 out of 4 people possess weapons, the 3D printer is the problem. I mean, there are companies selling industrial-grade firearms—why the heck is the 3D printer the target?

[–] SaveTheTuaHawk@lemmy.ca 2 points 50 minutes ago

See Luigi.

It's not the gun, it's gun makers worried about DIY gunsmithing. The politicians are just the bitches.

[–] douglasg14b@lemmy.world 19 points 6 hours ago* (last edited 6 hours ago) (1 children)

It's not about firearms.

It's about controlling what you can 3D print.

When your 3D printer has to connect to a third party service to check if it's allowed to print what you just sent it. That's a clear vector for companies to enforce IPs.

Printing a replacement part for your appliance? Sorry, they're blocked.

Printing parts to repair part of your vehicle or snap something back on? Sorry, that's banned.

Printing something that resembles the intellectual property of any other company? Sorry, that's banned.

Can't have you cutting into the profits of corporations by self-servicing and self-repairing.

Also a mass surveillance device to produce surveillance of what people are 3D printing and report it to a central authority.

[–] MatSeFi@lemmy.liebeleu.de 2 points 5 hours ago

Ok however its hard for me to believe that such measures could render effective. Regulating the tech literate people in such a way will always fail. The only effect it could have is that when its illegal to posses a unregistered/hacked you are an easier target for "law enforcement actions"

[–] Wilco@lemmy.zip 4 points 9 hours ago

Because money. Firearms are everywhere in the US because of gun lobbyists. If citizens print their own guns then money is lost.

Printing guns wouldn't be a problem if you just make all bullets cost $5000.

[–] CADmonkey@lemmy.world 2 points 1 hour ago

Bullets are even easier to make than firearms.

[–] SalamenceFury@piefed.social 4 points 3 hours ago* (last edited 3 hours ago)

The second amendment itself prevents ammunition from being marked out of people's budget. Two, people could just reload their own bullets. Three, bullets are extremely cheap to manufacture and making them cost that much would be a scam on the levels of health insurance companies. Also, did you forget about what a certain bearded man said in 1898?

[–] popekingjoe@lemmy.world 6 points 8 hours ago

Damn that guy must've did something! They put $50,000 worth of bullets in his ass!

[–] billwashere@lemmy.world 128 points 18 hours ago (21 children)

If they were smarter, which they are not, they would look to place restrictions on the slicer software. I doubt the printers even have the capability to recognize what is being printed. Most of them are like move left 3 steps, extrude .1mm of filament, move right 1 step…. yada yada yada.

This is just insanely dumb. They are essentially trying to regulate technology they know very little about.

[–] rushmonke@ttrpg.network 1 points 5 hours ago (1 children)

Slicers are open source so anyone can and will remove surveillance malware from it.

[–] AllNewTypeFace@leminal.space 1 points 4 hours ago (1 children)

Require printers to check digital signatures on STL files and have only approved slicers add those

[–] rushmonke@ttrpg.network 2 points 4 hours ago

So we're back to placing restrictions on the printers...

The last half of the 2020's is going to be remembered as when we lost all anonymity and privacy.

I guarantee by the end of the decade we get on-device snitches (to protect the children!) that profile and report everything you do, everything you type, everything you view.

Just leave me alone. Let me think my thoughts.

[–] krashmo@lemmy.world 13 points 11 hours ago

Then refuse to participate. Use open source software and any other kind of system outside their control until they throw you in jail. That's what I'll be doing. If enough of us do they can't jail us all. Participation is consent.
