      Most of these studies focus on implementing a semi-automatic. Here the problem is going to be the higher case pressures of modern ammunition. If they made a 3D gun to an older spec (e.g. 45 Colt revolver cartridge instead of 45 ACP) they would probably have better results.

        It depends on use. A criminal could be well off with a small caliber firearm because the threat of the weapon is what he needs more than actual firepower. A legal owner is going to expect that what he has is going to last through thousands of rounds. A crook just needs it to fire a few times, and if it is used for firing, it will be at point-blank range.

        what's the difference between a lower and an upper? which part has the barrel? or the trigger and "chamber"?

        Barrel, chamber and bolt assembly go on the upper receiver. The trigger, magazine, stock and serial number on the lower receiver.

      • Upper is the top part of receiver it connects to the gas system and the barrel

        lower is ... the bottom part of the receiver it contains the trigger group

        this is a very simplified explanation but should suffice

      • the upper of an AR platform (based on the Stoner design) mounts the barrel and houses the bolt and bolt carrier.

        the lower has the magazine well, mounts the trigger mechanism, and houses the buffer and buffer spring housing (around which, the stock is mounted).

        the chamber is an area of the barrel that holds the cartridge for firing.

The metal deposition, selective laser sintering types that make metal parts are much more costly and not nearly as widely available, but those can, depending on the material and method) make viable gun parts that will withstand the loads for several rounds before succumbing.

    Here's a gun that was 3D printed using DMLS (Direct Metal Laser Sintering) for the metal parts and SLS for the grips. It's both durable and viable.

      Well technically 3D printing refers to the process of using an inkjet, the very same inkjet from a regular printer, to deposit a binder on a layer of powder. 3D printing is just one Additive Manufacturing process.

      Now DMLS and Laser Sintering(SLS is a trademark of a particular company) aren't quite yet ready for consumers yet.

      Laser sintering of plastic requires inert gas, messy plastic powder, and messes up if temperature varies even a tiny bit(sintering scales with T^4). Messy doesn't even begin to describe how dirty these machines are. You can almost taste the powder in the air near these machines.

      DMLS uses explosive metal powder, requires inert gas, and a pretty dangerous laser. But the real kicker to DMLS that makes it ill suited for the consumer market is the support removal. In order to prevent the printed parts from deforming and to dissipate heat, one has to print supports in. In other words, after printing you have to go in and do a bunch of sanding and dremeling to remove METAL supports from the part!

      LOM is pretty much just for making stuff out of paper, so one probably wouldn't be able to make a very good gun with it.

      SLA can really only do plastics and ceramics. And doing ceramics requires a special kiln.

      However, SLA might be coming to the consumer market due to it's simplicity, speed(there's indications these machines could print very fast), and resolution.

  • Since they have found these guns are completely useless, then hopefully they won't enact legislation to require all 3d printers have crippling DRM that makes it impossible to print guns.

    What we in fact see is that the object that "barely travels any distance at all" is the spent shell casing. This is completely fine as the aim is not to magically embed the spent shell casing into the target. That is what the projectile part is for. The projectile is likely to have whizzed off as expected, albeit not with great accuracy.

    As for the general usefulness of plastic firearms, even if they can only fire a few shots, there are clear advantages.
    1. You can obtain a firearm without it being registered to you or exposing yourself to criminal firearms dealers/police sting operations.
    2. They are less detectable.
