Luigi would have passed a background check.
And didn't even use his own printer (according to his confession/manifesto)..
was it even printed in new york? I mean im sure someone would never bring one in from jersey.
Everything is legal in New Jersey.
Why do you print like you're running out of time?
- FOR PURPOSES OF THIS SECTION, "THREE-DIMENSIONAL PRINTER" MEANS A COMPUTER OR COMPUTER-DRIVEN MACHINE OR DEVICE CAPABLE OF PRODUCING A THREE-DIMENSIONAL OBJECT FROM A DIGITAL MODEL
Well, that's a broad definition. I guess to whomever wrote that, a CNC mill is also a 3d printer.
It's not like inkjets produce 2 dimensional ink. I'd love to see someone argue in court that it's technically impossible to create a non 3d printer
Well achtually........To be pedantic,
A 3D consumer grade printer is not a true 3D tool since it can only move on 2 axis simultaneously. If you watch your printer closely, as it finishes it's path around the xy plane, there is a tiny halt as it changes active plane from the xy plane to xz plane, lifts the nozzle, then flips the active back to the xy to go along it's merry way again to lay down the new layer. And no, the hot new scarf joint is still a single plane movement. Sometimes such machines are incorrectly referred to as 2 1/2 axis because they aren't true 3 axis.

A CNC mill seems much more capable of manufacturing firearms than some 300 buck printer.
Not really.
There are gun parts that just can't be printed in plastic (reliably. There are proof of concept "all plastic except the firing pin" guns). But... because of how lobbyists tainted what few gun control laws we have, most of what makes a gun a gun CAN be printed and the rest can be bought as after market parts. That is why an incredibly common "ghost gun" is basically "print this and then go buy this replacement barrel and this baggy of parts to repair a glock".
Whereas a mill is great for those metal parts and you can theoretically mill an entire gun, it isn't going to be a gun you "want" to use and, odds are, you are going to need a lot more technical skills. And for stuff like "ghost guns" and the bootleg mods used in stuff like The Troubles? A 3d printer is MUCH more accessible and MUCH easier to make.
The reality is that neither is going to be effective in the case of a militia/uprising scenario (yes, you can print an AR-15 and it isn't THAT hard to reinforce the plastic to handle intermediate rounds. No, you can't print a hellfire missile or a predator drone or a tank). And for the purposes of a school shooting? Why print a gun when you can just grab daddy's glock out of his nightstand or junk drawer?
I'll also add on the reason why additive manufacturing is so loved by Industry. Milling is subtractive. You get a piece of stock and you cut it until it is the part you want. If you can guarantee said piece of stock is approximately the same dimensions every time, you can automate that. But getting a piece to those dimensions has a significant cost. 3d printing? As long as you clear out the build plate and sort of control the environment, it is the same operations every single time.
So to 3d print a glock? You go to one of the naughty sites, get the STL, make a few tweaks to your slicer, and start it (old Vice actually did a really good video on this). After that you wait until it is done, remove the supports, file the ever loving hell out of it, and you are ready to go blasting.
To mill a glock? You go to one of the naught sites and get the gcode. You then adjust that gcode to fit the dimensions of your piece of stock (or put in the time to make your piece of stock the dimensions the gcode is expecting...). You then do one process, stop it, move and remount the part precisely to expose the correct surfaces, and do the next process. And so forth.
You can also technically make a gun with generic plumbing supplies or you could finagle one with random garbage and a drill bit.
May I introduce you to TM 31-210?
THIS IS AMERICA! You can't post stuff like this outside of a classroom!
Anything to avoid having to actually address the systemic poverty and bigotry ingrained in the system that leads to violence...
From what I understand the "problem" as it's being framed in terms of ghost guns and inner city crime or whatever the buzzword is this year is not hobbyists running off a lower or frame for themselves. None of those guys in the hood and their switches are buying Bambus or building Vorons and suddenly turning into 3D printing gurus -- Someone, or several someones more likely, are deliberately mass manufacturing these things for sale to the criminals which is already thoroughly illegal. Find the gun runners and stomp on them. I thought you guys were supposed to have this big scary police force and surveillance apparatus?
Awful. Literally banning science, because it can be misused.
We'd better go the full mile. Here's my list of things to be banned, For Our Safety^TM^:
- 3/4" and 1" galvanized steel pipe and endcaps
- Cases of matches
- Acetone
- Stump killer
- Milling machines
- Lathes
- Drill presses
- Hydrogen peroxide
- Salt, Sodium Chloride
- Stainless steel bolts
- Benchtop power supplies
- Sulfur
- Carbon
- Water
- Aluminum foil
I'm sure I can think of others if you give me a minute or two.
Gonna require background checks to get plumbing supplies or to go to the hardware store? Cause I can make a gun a hell of a lot easier and quicker with that shit, than I can with a 3d fuckin printer.
How stupid, I use my printer to print minis for DnD. But, wait, it could theoretically print a gun, better get a background check, and have a waiting period of 6 months... fucking stupid.
Let's try to address the problems that led to this. Nah, let's try to ban stuff instead.
It won't even be effective. As I pointed out earlier, hoodlums in the ghetto, who are the implicit targets of this, aren't buying Bambus and becoming 3D printing experts overnight just to run off one off-the-books Glock. Someone with five or six brain cells to rub together is printing guns in quantity and selling them to the criminals. Anyone willing to employ that business model can and will simply kit build a printer rather than buying an off the shelf unit, which is certainly not difficult to do. It just adds one extra step to the operation for anyone who truly wants to do this, and 3D printing a working firearm is already a pretty decent commitment especially if you're not already an experienced printer. Especially Glock frames.
Tell us your corporate paymasters are afraid without saying they're afraid.
Are they going to require background checks for purchasing metal working equipment? Or maybe just make it illegal to bring any metal to melting point without a license.
Because you can make guns with metal.
This is braindead, are they gonna require background checks for the hardware store next?
You literally need ID to purchase silverware in the UK. Yes, they will absolutely do this.
Some actual gun control laws would be better, not to mention universal health care. What’s next on the list? Kitchen knives? Pans, pots? ;)
This is absolutely the best action we could take to address the gun violence problem.
Tighten background checks for guns: ✋ Tighten background checks for 3d printers: 👀
"People are 3d printing guns, should we require background checks on the required barrels/trigger mechanisms/ammo/magazines/rails etc?
No! We should require checks on the universal machine that can among a billion other things manufacture the plastic parts!"
Any engineer worth their salt can do this without a 3d printer. Idiots.
~~Keep in mind that this is a state that bans nunchuks.~~
Never mind, NY banned nunchuks in 1974 but then in 2018 a federal court decided that New Yorkers have a 2nd amendment right to nunchuks.
Maybe there's a constitutional right to keep and bear 3D printers too? If your life is in danger, you can use the concealed printer you're carrying to make a gun and then defend yourself with that gun.
Don't worry, my state considers throwing stars to be "assault weapons" now and their sale and possession is banned. There's still stupidity abound if you care to look hard enough.
their sale and possession is banned
How will I assassinate the Shogun now?!
Oh my god it's back? I was hoping we'd seen the last of it back in 2023.
