California's new bill requires DOJ-approved 3D printers that report themselves

Sometimes I wonder what Adafruit's first language is.

Of course the Bill does not require DOJ-approved 3d printers.

zachrip•51m ago

alisonkisk•8m ago
Title: "California’s New Bill Requires DOJ-Approved 3D Printers That Report on Themselves"

Actual fact: California’s New Bill Requires that 3D Printers Get DOJ Approval as Firearm-Blocking"

(The "report on themselves" is fiction invented by Adafruit.)

vel0city•49m ago
I don't know what language you speak but here is a part of the bill in English

This bill would require, on or before July 1, 2028, any business that produces or manufactures 3-dimensional printers for sale or transfer in California to submit to the department an attestation for each make and model of printer they intend to make available for sale or transfer in California, confirming, among other things, that the manufacturer has equipped that make and model with a certified firearm blueprint detection algorithm. If the department verifies a printer make and model is properly equipped, the bill would require the department to issue a notice of compliance, as specified. The bill would require, on or before September 1, 2028, the department to publish a list of all the makes and models of 3-dimensional printers whose manufacturers have submitted complete self-attestations and would require the department to update the list no less frequently than on a quarterly basis and to make the list available on the department’s internet website. The bill, beginning on March 1, 2029, would prohibit the sale or transfer of 3-dimensional printers that are not equipped with firearm blocking technology and that are not listed on the department’s list of manufacturers with a certificate of compliance verification, except as specified. The bill would authorize a civil action to be brought against a person who sells, offers to sell, or transfers a printer without the firearm blocking technology.

https://leginfo.legislature.ca.gov/faces/billTextClient.xhtm...

Let me point out the statement:

> The bill, beginning on March 1, 2029, would prohibit the sale or transfer of 3-dimensional printers that are not equipped with firearm blocking technology and that are not listed on the department’s list of manufacturers with a certificate of compliance verification, except as specified.

It seems pretty clear this would prohibit the sale of 3D printers that are not approved by the California DoJ.

It's not nice to lie about extremely obvious things.

the goal is you cant sell a 3D printer without attestation that it is anti firearm compliant.

now they have to do 80% printers, kits composed of not a printer subunits, to be assembled on site.

You have described the lawmaking process of basically any country. We can't actually write laws to solve real problems because real problems are hard and you can actually tell whether they've been solved or not, but we can write laws to solve imaginary problems and then when nothing changes declare victory.

You can pretty much tell when any given administration has run out of ideas once they start making a huge amount of noise about laws that affect to first and second order literally nobody. 3-D printed guns is basically California's version of illegal immigrants voting in elections. Both things happen to a vanishingly small degree that it's not worth taking any action on either, but you can make them sound like they're the greatest threat to America if you have a megaphone loud enough.

> Both things happen to a vanishingly small degree that it's not worth taking any action on either

Eh, small thing there. Ever notice how when discussion about voter ID laws in the US come up that commenters from other countries are absolutely blown away by the idea of not having to show an ID when you vote? Because it’s such an obvious thing to not just leave up to the honor system, like we do? Point being, everyone else seems to think this “thing that could never happen” is worth safeguarding against.

Spivak•20m ago
You're right it's a very obvious thing that you should have to show your government issued ID to verify who you are to a civic function, and that relying on the honor system is something that seems like it could never work because elections are serious and people have vested interest in particular outcomes and so would obviously look to cheat.

But this is what I'm talking about it being a theoretical problem. It's so obvious that this could be an issue but it's not an actual issue and the USA stands as an example that, counterintuitively, you actually can rely on the honor system. And so because the system currently works as it is and there's no real problem to point to I think it is reasonable to be inherently suspicious of the motives of a government that wants to make a thing harder without being able to point to a concrete problem.

A less controversial example on hacker news would be having to show your government ID to access porn. We are all rightfully suspicious of the motives of a government that wants that when to most Americans it is plainly obvious that there is not a real problem being solved. It's so obvious that you should have to show proof that you're 18 in order to access 18 and up material but we have more than two decades of proof that just asking them if they're 18 and up works well enough.

xienze•32m ago
> Regulating actual guns that are frequently used in crime? Unlikely.

Well, two things. First, your phrasing implies there’s no regulations around firearm ownership at all, which is not true.

Second, much to the chagrin of California and similar states, that pesky second amendment exists. Which makes the kind of regulations they _want_ around firearms (i.e., regulate/tax them out of existence) kind of tricky. But presumably regulations around what you can do with a 3D printer are much easier to handle from a constitutional perspective.

WillPostForFood•47m ago
It is pressure from the gun control lobby. Everytown for Gun Safety, a gun control group, is the brains behind it. The states moving this legislation (California, Washington) are very hostile to gun ownership, and already have bans on assault rifles and printed guns. This is just another step in tightening the noose.
kube-system•42m ago
Politically the US is very much not a monolith on this topic and many states and localities have passed laws that were later struck down as unconstitutional. This is a bill in California, which does have about the strictest laws that the federation allows them to have, and they would place even stronger restrictions on guns if they could. This is not really ironic as much as it is pushing the envelope for gun control as far as they legally can.

But also, California regulators likely see the regulatory landscape as the reason this law is needed rather than in spite of it.

Gun manufacturers are likely against these types of regulations because many of them would affect manufacturers and the tools they use too.

guelo•12m ago
> strictest laws that the federation allows them to have

Note that "the federation" allowed states to have stricter gun laws until recently when we got a new partisan supreme court that is out of step with the previous 200 years of jurispudence.

thom_nic•39m ago
> is this pressure from the gun manufacturing lobby

Definitely not, it's pressure from the anti-gun lobby that keeps pushing "one more bill that this time will actually change violent crime statistics, we promise!"

These bills are being introduced in the states that already have the most restrictive gun control already, yet to nobody's surprise, hasn't done much to curb violent crime. But the lobby groups and candidates campaign and fundraise on the issue so they have to keep the boogeyman alive rather than admit that the policies have been a failure.

pear01•19m ago
It is hard to police guns when there is free travel between the US states, yet only individual states can be relied upon to pass any reform. A broken federal government means guns are easily exported from red states with practically zero gun laws to blue states where they are used to commit crimes. States are often forced to recognize rights granted by other states because such an interstate jurisdictional question naturally bubbles up to the aforementioned dysfunctional federal system.

Similarly to how many (most?) guns used criminally in Mexico actually come from the United States.

Edit: I'm not surprised by the downvotes, but I am amused. These are objective facts. Any basic research will yield many studies (including from the American government) showing that the majority of guns used in crimes in Mexico are traced back to the States. Americans love the boogeyman of dangerous Mexican cartels so much they never seem to ask themselves where these guns come from in the first place. Hint: look in the mirror.

FireBeyond•11m ago
> states that already have the most restrictive gun control already, yet to nobody's surprise, hasn't done much to curb violent crime

The "most restrictive gun control" states in the US would still be generally by far the least restrictive gun control states in the rest of the developed world (you know, where gun-related deaths are a small fraction of here?).

Your answer smacks of "well, they tried and surprise surprise it doesn't work so why are we doing it?", i.e. "'No Way to Prevent This,' Says Only Nation Where This Regularly Happens".

mullingitover•10m ago

Claims made without evidence can be dismissed without evidence, so consider these dismissed.

Now for the evidence[1]: it's a documented, empirical fact that there is a marked correlation between common-sense gun laws and reduced rates of gun deaths.

"documented, empirical fact"

I won't try to make as strong a claim as the person you are responding to, but unfortunately, the politicized nature of the topic makes research on gun violence, especially as it relates to gun laws in the US, extremely fraught. The vast majority of research articles are plagued with issues. One should not just blanket trust the research (in either direction, and there are definitely peer reviewed journal articles pointing in different directions).

The claim you responded to was too strong, but for similar reasons, yours is also far far too confident.

It's the anti-gun lobby. Bloomberg's band of morons who believe a government monopoly on force is good.

These bans are almost exclusively in states with already extremely strict (high rated by the gifford's law people) gun laws.

So far, there is zero evidence in the last 30 years more strict gun laws have curbed crime. The states with the strictest laws conveniently have the highest proportion of gun crime. The same people writing these laws don't understand what "per capita " means. Nor are they willing to confront the reality of what the data shows. The calculus for these petty tyrants has changed from banning guns wholesale to lawfare. Make owning and purchasing firearms so burdensome the market dies, and with it, the rights. This is just another play in that strategem.

Fun fact: More people died last year putting foreign objects in their rears than by AR-15s. That is how insane the anti-gun lobby has become. They are literally barking at their own shadow these days.

It's like saying "I am baffled by Europe, look at what Hungary is doing ..."

For example, some states don't need any permit to open or conceal carry, some have no minimum age requirements to buy guns, and the majority don't have any mention of 3D printed guns.

Federal law applies then about untraceable guns and or arms that cannot be detected by metal detectors. But those predate 3D printers as we know them today.

SilverElfin•10m ago
It’s pressure from the anti gun obsessed nonprofits on the left like Everytown. Bloomberg has nowhere else to waste money and there are legislators willing to present bills authored by Everytown blindly. But in many cases gun control bills are known to be unconstitutional and pushed through anyways. It takes years for laws to be ruled unconstitutional by the Supreme Court and even if they are, states like Washington or California or Oregon will just pass the next Everytown authored unconstitutional bill with a slight variation.

The real fix is that we need to get rid of immunity for legislators. When they violate the civil rights of the constitutional rights of citizens through their actions, they must be held personally liable and must go to jail.

Let's look at actual numbers. ATF says 50,000 guns were smuggled into latin america between 2015 and 2022. So about 7,200 a year. There are about 15-20 million new firearm sales per year in the US.

So assume ~.03% of production gets smuggled out. I think the industry would survive if that was cut that off. It actually would be better for them because it would make lies and slanders about the industry harder to make.

Besides that, you could break anything up into parts that don't necessarily look like the complete article.

US requires only the serialized part of a firearm treated as guns. For the AR-15, which is like PC/AT of guns, it's a nearly cosmetic part of it, sort of a motherboard backplate. Or like, a collar for a dog rather than the heart of a dog. As such, that part reportedly can be printed and used to shoot live rounds fine. Most other guns apart for AR-15 don't even matter, like how an E-ATX motherboard with dual PowerPC hardly matter in any talks concerning a PC - if you'd be wondering what about Raspberry Pi, that would be SIG P320 or something like that.

In most place of the world, including where I am, pressure bearing parts such as the barrel, the bolt that locks onto the end of the barrel to seal it as it fires, the firing pin that ignites the cartridge, the live cartridge containing gunpowder, etc etc, rather than the part that merely carries its nameplate, are controlled. It is illegal in such places to buy or possess functionally relevant parts of a gun, at least without a license, and/or prior approvals. This is more like buying a CPU or motherboards would be controlled rather than cases and faceplates. In some places, what is considered a gun in US hardly qualify as such, even almost slipping through customs(allegedly).

You guys gotta fix that broken classification before trying to offload onus onto the global 3D printing community. Or drop it altogether.

What people don't realize is that gun control works, but only when it's very controlled - i.e. full registration, deep checks, mandatory training, strict storage, no handguns, etc.

You need to do it across the whole country, as a real customs border can cut guns significantly, but in the US you can do still do a private party (person to person with no dealer) transfer in many states, making gun running pretty trivial.

None of this will happen anytime soon in the US, and the ghost guns, etc. thing will keep happening.

CNC mills, laser cutters, and waterjet cutters can all produce the same end result but fall outside the statutory language. So the bill doesn't regulate the capability — it regulates the specific manufacturing process. Which means it's trivially circumvented by anyone who actually wants to make something prohibited, while imposing DOJ-reporting requirements on every hobbyist, educator, and small manufacturer running a $200 Ender 3.

This is the pattern with most hardware regulation attempts: the compliance burden falls on the people already operating in the open, while the actual threat model (someone with intent) routes around it by switching tools or buying across state lines.

I wonder how "significant technical skill" will be interpreted in practice. That phrase likely means something different to the average HN reader than to the average congressman.

California is no longer progressive.

I think this isn't about guns but more about seeing and controlling what people are printing. Guns is just the excuse to monitor.

"Hey I see your printing a replacement part for you washer. Well that is a patent part and you will need to pay to print that."

It's legal to manufacture your own firearms. Putting limitations on 3d printers just makes people who want to this's lives harder and stifles innovation.

It's legal insofar that if you want to exercise your rights expect to sit in Jail until your lawyer can take it to the Supreme Court. At which point CA will slightly reword the law to intentionally circumvent the Constitutional rights of its citizens.

I have no idea about CA but this is absolutely the case in NYC.[] Dexter Taylor is sitting in jail for a decade for making personal use firearms without a license. No other alleged criminal activity and they never even left his house. During trial, the judge said "the second amendment isn't allowed in my courtroom."

His lawyer knows they are going to lose all the appeals in New York but basically he has to sit in jail for 3-4 years through the state court system until it can hit federal courts where there is a good chance his case will eventually get overturned.

It's highly misleading to call a bill that was introduced a couple of days ago by one Assembly member "California's new bill". Bills aren't laws and most bills go nowhere.
