On today’s episode of Uncanny Valley, we discuss how WIRED was able to legally 3D-print the same gun allegedly used by Luigi Mangione, and where US law stands on the technology.

    No plastic can withstand the pressure and shock from the propulsion of the shot, nor the heat or the friction generated. The 3D printed whatever is a fallacy. The only thing you can print is cute things you can attach to whatever.

      Uhhhh my friend you can print a 9mm CZ scorpion that shoots as well as the real thing. Same with an MP5. You can find videos of them being tested and shot on the internet. A lot has changed in the past few years with 3D printed guns.

      https://youtube.com/watch?v=kucefQ6sYbo there are silly videos too

      Of course, they are not 100% plastic, but that’s irrelevant. They can be made at home with little effort using a 3D printer and from simple materials anyone can buy at a hardware store, without any registration or serial numbers.

      A lot of “real” guns are made from plastic, too, btw

      How do you mean? You 3D print something with no serial and it’s untraceable. Even if they find it they can’t definitively say your firearm shot the bullets. Unless of course you’re on video doing it and admit to it.

        Something tells me not doing that part is going to be harder for a significant portion of today’s population than getting a weapon.

        Except for all the metal parts they used a debit card/paypal to buy.

          Those would hard to teace and yu can pay cash. How many stores sell metal pipe withthe same inner diameter as a 45 caliber. It would be lole tracing meth lab by ammonia sales.

          Yeah, you can’t easily print an entire gun, but the parts you buy don’t necessarily tie you to the gun.

          The only regulated parts (I know of) are:

          • receiver (considered the actual gun, this is the bit they print)

          • suppressors (not printable but you can make these homemade, though not as good and definitely not as reliable.)

          • autosears (or anything else that makes your gun fully automatic, or even act like it, usually these are super basic and printable)

          • big magazines (not federal but a lot of states have laws on em’ Usually states with these laws will allow big ones to be sold with rivets, so they can usually be converted with a drill and new spring. Also they’re just boxes w/ springs so you can print one.)

          They’re also starting to Anodize rifling into barrels using cheap 3D printed jigs, so some of the metal parts are now getting homemade too.

            autosears

            Autosears themselves are not actually regulated. It’s the action of fully automatic fire that is. Which is kind of ridiculous because it’s not terribly uncommon to have a gun do it by accident on worn out parts.

          The components aren’t traceable either. They don’t have serial numbers on them. Typically only the lower receiver does. This is why that’s the part that’s typically 3D-printed.

        when you fire a gun scratches are left on the bullet that are enough of a unique fingerprint to trace to the gun.

        Didn’t Luigi get caught with the weapon in his backpack? The title picture on this article is literally him. If it’s untraceable by printing, it seems you’d want to not have it on you if apprehended.

          Common plan for professional hitman is to drop the gun at or near the scene. With a ghost gun what could tgey trace back

          Factually, they illegally searched his bag without a warrant at the mcdonald’s, repacked the bag, put the bag in a police vehicle and drove to the police station without bodycam, and then turned bodycam back on to search the bag again and instantly “find” the ghost gun in his bag, which, without a serial number, is conveniently impossible to prove it was not planted.

          https://www.wtaj.com/news/local-news/new-photos-show-luigi-mangiones-arrest-defense-argues-for-evidence-to-be-suppressed/

          The motion goes on the state that once that officer’s body cam footage resumes, it shows her immediately re-opening and closing the backpack compartments she already searched and then opening the front compartment of the backpack “as if she was specifically looking for something. Instantly, she ‘found’ a handgun in the front compartment.”

              Almost like the lawyer thinks “they didn’t follow procedure” is an easier legal argument than “the police dept is trying to frame my client”.

                The gun isn’t the only evidence. All they’re doing is drawing attention to the fact that it was his gun by not denying it was his and trying to get it excluded from evidence. Even if they win this argument and get the gun excluded, they’ve basically confirmed that the gun was his in doing so.

                It does if you want people to believe the gun wasn’t yours. The gun isn’t the only evidence, and not denying it’s yours but trying to get it excluded from evidence confirms that it was yours and you’re trying to hide it. It screams guilty.

          Yeah but they have video of him too. Idk the case well enough but I assume the gun itself wasn’t enough to prove he did it.
