I got a call from the school principal. She said “another parent called and said your son 3D printed a gun and brought it to school”.
I looked at the print history. It was a tiny toy mandalorian figurine holding a blaster pistol in his hand.
I bought my son a bigger 3D printer and told him to stop playing with that boy.
Then you have situations like the young kid that did bring a gun to school and shoot a teacher, and there were tips not followed up on, and the school getting absolutely dragged through the court of public opinion because of it.
So, the adults in this situation are in a difficult position. They've got 5 year olds telling them things that are very unreliable but very concerning, and they do need to actually consider that 5 year olds might have guns.
What happened to you is probably the best case scenario: kid told their parent something incorrect, that parent calls the school, the school checks in with you, you tell them they're wrong, the end. If the principal actually thought there was a problem, I doubt she would have simply called you.
I can't think of a better response to that situation. I'm going to use it when appropriate for my own kids when the time comes.
Also - your kindergartner is autonomously searching for 3d printer models and executing prints at that age? That's awesome. Curious what 3d printer and what mechanism he uses to search and initiate prints.
I tried basic elegoo and bambu printers.
He can’t read very well but he likes dragging shapes around on a tablet.
He would ask me to find shapes using the search engines then he mixes them together or reshapes them.
I would add them to his history.
This is why I was surprised to hear about 3D printed guns. I was quite sure there wasn’t anything like that in the history.
It was a good discussion topic about why adults get so bothered by things that look like guns.
I think that's because parent-child is the strongest bond known to humanity, so anything symbolic of (or against) child safety evokes the strongest emotional responses we can ever have.
Guns, when loaded, are one of the extremely few consumer objects capable of being held in a child's hand and, with a physical ease similar to changing TV channel with a remote, destroy or end a life. (and, of course, one of the first rules of guns is "always assume it's loaded")
And so - especially in a country like the USA where guns are a prominent part of culture, and thus talked and thought about a lot - the conflation of the above means that for a significant cohort of parents, guns are one iconic symbol of their ultimate nightmare : losing their child somehow.
The fact that the USA needs separate Wikipedia pages per decade in order to make the summary list of school shootings manageable is illustrative of why some have developed such phobias. https://en.wikipedia.org/wiki/Lists_of_school_shootings_in_t...
Hands up if you’ve ever been told you can’t do something because of potential SOC2 audit non-compliance. Or it’s against GDPR. Or legal won’t allow it. Or it’s against IT security policy. Or just against “policy”.
1/ Some top-level authority writes down a rule saying “as of 2021, it is forbidden to have red pencils”.
2/ The authority might prosecute one or two cases, but most enforcement is largely farmed out to certification bodies: the lawyers, auditors, inspectors of this world.
3/ No auditor or auditee ever wants to be the first to fall foul of PNCL21 regulations. The expense one would incur of being a test case incentivizes every regulation to be widened in scope, unreasonably, to try minimize risk.
4/ Moreover, there is a purity spiral incentive as an auditor to maintain the illusion you know what you are doing and therefore justify your $500-a-day fee. No widening-of-scope is too much! No one ever got fired for buying IBM, and no one ever got fired for banning pink crayons “just to be safe”, even though no normal person would call them either red or a pencil.
Cylindrical graphite rods stored in the same building as red paint? Audit failure risk. Orange pens on your desk? Audit failure risk. Office within 1000 yards of a stationery shop? Audit failure risk. You are single, own a traditional twig-broom, and you like black cats? Audit failure risk, I say!
Not a huge fan of overly broad CoCs, but they arose because, in fact, that simple rule did not work fine. It repeatedly did not work fine, in many groups engaged in many different endeavors. It worked not fine so badly and so frequently that people got tired of it and started writing out the explicit rules.
There's a lot of parallels between CoCs and sexual harassment rules. At first, it was a shitty free-for-all that was fun if you were part of the getting-away-with-it group but terrible for others. Then people said alright, had enough, we're going to make hard and fast rules against all this bullshit. Those first versions tended to be awful and heavy handed because they tried really hard to be comprehensive and serious about it, which is very well intended, but probably too far in the other direction. What we ended up with is probably vastly better, on average, for all involved. It's not as fun for people who enjoy treating others badly, but a whole lot nicer for everyone else.
Before that when it was still in the assembly, I wrote to Matt Haney, which didn't do much good because he voted for it both in committee and for passage.
But, I feel like bay area legislators need to know many of their constituents know this bill is misguided and are paying attention. The tech capital of the world shouldn't have artificially impaired tools.
If you want different laws, you need to elect different politicians.

In case it is not clear to anyone reading, this is kosher political speak for "I am ignoring automated emails. Consider this your notice."
Honestly, I am surprised it took this long, although I'm quite certain it has been going on for a lot longer and generally they simply do not provide the courtesy of telling you they are ignoring you.
Or if you couldn't buy scissors (because they could cut brake lines).
Or if you couldn't buy a car (because it could be used to run someone over).
And if all of those checked with the government before functioning.
It's almost like maybe instead you should just ban the undesirable end action, enforce that law, and create societal conditions that don't nudge or force people into doing undesirable things.
They cannot take this shit away. It's futile.
The undesirable action is shooting people, right? That's still banned.
It seems like you think the undesirable action is publishing plans for machines you don't want people to have.
Which parts of a firearm can be printed in a consumer-grade 3D printer? Be as specific as your knowledge permits.
Of those that cannot, how much money does one have to spend in order to purchase a 3D printer that is capable of printing those parts that cannot be printed by a consumer-grade printer?
Are you aware of "slam fire" firearms? If you were not, you owe it to yourself to learn how to make a functional "slam fire" shotgun. The tutorials are pretty widespread.
I don't know the details of what can be printed in a consumer-grade printer, not having performed firearms manufacturing myself, but I've seen things claiming to be pretty complete kits and it seems to me that most components should be possible. Barrels of any reasonable length might be hard, perhaps firing pins too. (And springs, but of course those are trivial to manufacture by hand.) If it's not actually possible to 3D print an effective gun, perhaps someone should make that argument in detail.
A lower receiver is not complicated. It essentially just a quirk of the law that the ability to 3d print a lower receiver is useful to people who want to manufacture “untraceable” guns.
You could change the law so that barrels have to have serial numbers and accomplish nearly the exact same thing as completely banning 3d printers.
Also buying a kit, 3d printing a lower receiver, snd assembling an effective firearm is about as difficult as buying a kit to assemble an 3d printer and using existing open source slicers (or modifying a 3d printer to let you use an open source slicer).
And if 3d printers are as dangerous as the proponents of this legislation thinks they are, people would just hop across the border to Nevada and use a 3d printer there.
Califoria would not be a sanctuary state if they actually cared about enforcing laws.
Where's William Osman, Adam Savage etc talking about this?
im looking forward to the idea that the outline of Ca. may trigger false positives
Maybe it would be possible to just embed a prompt injection into metadata or the STL mesh itself.
People will make banana, cucumber, corn, sausage, etc shaped guns.
There will be guns with electronic triggers where the trigger could be a universal TV remote or an RC car remote.

This is, by the way, very similar to attempts to curb down the right to repair, or more recently the age sniffing that also tries to destroy VPNs. Lobbyists are getting rich right now. It's amazing to see how corruption works in the USA here.
This joke of a law isn't going to stop any 3D printed handguns from getting made, it will only add one more relatively easy step.
Then what, ban stepper motors?
Don't give them ideas.
But seriously, given that the 3D printer movement started out with people building their own printers from scratch and there continues to be a healthy open-source hardware ecosystem within the community, I can't see this stopping anyone.
Unless you also make it illegal for 3D printers to print 3D printer parts...
You've come a long way, RepRap.
I don't think we will have much of this in Europe because guns are pretty rare here and so is ammo. We just don't really have gun problems except with organised criminals but they don't 3D print them, they just buy them.
But anyway, 3D printing isn't rocket science. It never was and it sure isn't now. Anyone can build one in their garage and many of us have in fact done so when it was a new tech. If someone wants to be printing gun parts they are going to be printing gun parts.
I support gun control.
This feels like theater, not gun control.
In America the problem is really more that people can just buy guns, not the printers.
When he says it has no gun control laws he's thinking "after 10 days you can buy a pistol".
Poor choice of words on his part perhaps, but I think it was pretty obvious what he meant if you're not nitpicking.
We still do similar things now, though for ostensibly different reasons. Inkjet and laser printers have long had various signatures they add to every printed page, barely noticeable to the naked eye, that can lead back to the specific printer used. The stated motivation is to prevent counterfeitting. Similarly, there is a pattern of "O" symbols called the EURion constellation that, if present in an image file, most commercial image editing software will refuse to print [2].
It's not surprising that politicians are trying these sorts of strategies with 3D printing, because they've already tried and used them often in the past.

- look up your local laws! usually you can photocopy money as long as it's shrunken / enlarged by a specific amount
- you can cover up everything but the EURion and see what it does to the rest of the copy
- you can cover up the EURion part of the bill and print out the rest
Again, particularly in the last point, be sure to look up local laws and set the printer scaling accordingly
