3D Printing

3D Printing Now Brings You Semiautomatic Pistols (The Better To Scare Control Freaks)

3D printed semiautomatic
Proteus/Defcad

It's not yet ready for prime-time (it has yet to be tested), but 3D printing tinkerers have developed a design for a semiautomatic pistol. In fact, the developer says a full-automatic version would be easier to make with available materials. What a long way we've come, in just a few short months, toward the ultimate goal of rendering gun control laws a complete joke. Well…they were already a joke (though a dangerous one). It's more accurate to say we've come a long way toward rendering such laws moot, and easily bypassed by even those with limited technical skills.

Over at DEFCAD, Proteus, a moderator and developer of the design (which another poster dubs "the brick" for obvious reasons) writes:

I have designed a .22 LR Semiautomatic firearm. Unlike former designs such as the Shuty, this design uses almost all plastic parts (All non-plastic parts currently except the FCG cannot physically be plastic or a semiautomatic will not function) and uses weights to bring the bolt to a correct weight. You will need the following parts:
*3D Printer with ABS capability
*AR-15 FCG
*AR-15 Buffer Spring
*Ruger 10/22 Mag Spring
*AR-15 Firing Pin
*1x8mm metal insert (Case extraction)
*.44 bullets to weigh down bolt (More info in the .readme)

The barrel uses an insert around the case, but then the rest of it has a plastic bore, which means it is pre-rifled and therefore complies with the ATF.

Magazines available in 10 and 30 round versions. NOTE, although they are based off of 10/22 magazines, they MUST be printed as they contain a built in mag-catch and will NOT work in a 10/22 rifle.

Strictly speaking the design isn't completely printed, since it borrows its fire control group from an AR-15. It also uses a nail as a firing pin, as do most 3D-printed guns.* As of yet, printing the relatively delicate working innards of a semiautomatic firearm on a printer isn't quite practical. That may change with a refined design, or when patents on selective laser sintering expire next year, bringing about an expected drop in the cost of 3D-printing detailed objects, including those made of metal.

Separately, Proteus writes, "Fully automatic would actually be EASIER than a semiautomatic to design (open bolt). However… I do not want to do this at this time because of the legal implications. But Fully automatic would be simple to create, including a printed custom FCG." As you might guess from an open forum like the one at DEFCAD, participants take pains to keep their efforts legal within the jurisdictions where they live.

What goes on in quieter developments, elsewhere, is anybody's guess. But if thinking about it makes the control freaks sweat just a little more, so much the better.

*Actually, it uses an AR-15 firing pin. I confused this point with a post discussing using a nail in a different design.

Update: Proteus asked me to clarify that DefCad is the search function, while FOSSCAD (Free Open Source Software & Computer-Aided Design) is the design community working on these innovations. Designs for "The Brick" are now available here.

  1. Cheap sci-fi was right, future guns will look like bricks.

    1. Only at first. Eventually you’ll be able to make them look like anything you want. Imagine what the control freaks will say when they realize you can print a gun that looks like an umbrella or a garden gnome…

      1. We’re talking about printing guns off the internet. They’ll all look like cocks.

        1. My design has a patented gungina(tm) that looks more like a fleshlight.

      2. I wan’t a unicorn shaped 223, with a thirty round horn

      3. You sound like a Batman villain.

  2. It also uses a nail as a firing pin

    Then why is there an AR-15 firing pin in the list of necessary parts?

  3. BANG BANG BANG BANG. Take that, beings of the third dimension!

    At least they’re improving on the look, which is the most important thing.

    1. At least they’re improving on the look, which is the most important thing.

      Dianne Feinstein agrees!

    2. Exactly. How else are the politicians going to know which are assault printed guns and which aren’t?

    3. +1 barrel shroud!

  4. Really, once they develop 3D metal printing, the game is over for effective gun control. A printed MG-42 would be fun…

    1. Never underestimate the government’s ability to regulate or ban something through sheer force of will.

      1. There’s a difference between getting the laws on the books and actually getting rid of the banned items. After all, we’ve decades of Drug War, and I can still get major doobage if I want it.

        1. we’ve had decades of Drug War

          The squirrelz stole my verbz.

        2. Who says we have to get rid of the items. It’s illegal to own one. We catch you with one, summary execution. If you survive, long prison sentence. If we catch or suspect you’re making them, SWAT raid. If you survive, even longer prison sentence because of intent to distribute. Now go forth and 3d print away.

          The DEA has never stopped the flow of drugs into this country, but they have no hesitation to fill our prisons up with the people they catch. Law enforcement is an industry, it creates jobs. YOu have to look at the long term on this. Take the long view.

          1. Yes, and all that level of violence has not appreciably lowered recreational drug use. At most, the violence lets authoritarian-minded people get their ya-yas out by beating up on “asocials” and employs some of our more goony citizens as enforcers.

            1. At most, the violence lets authoritarian-minded people get their ya-yas out by beating up on “asocials” and employs some of our more goony citizens as enforcers.

              So we’re back in agreement, being ineffective at banning the practice will not stop the government from regulating or banning it– and throwing the odd person caught with it in jail.

              1. But a de jure ban is not the same as a de facto ban, which was my point all along. Just because there is gun control does not mean that it’s effective. Basically, if I can acquire the prohibited item with only a very minimal chance of getting caught, I have no economic reason to care if it’s illegal. Hell, porn was and still kind of is technically illegal, but the digital fapping revolution pretty much totalled the government’s ability to ban it.

                1. Then we’ll just have to agree to agree. I hear what you’re saying, and you’re absolutely right.

                  My point was simply that by even trying to ban it, they create oppression– and often arbitrary oppression, a-la the war on drugs.

                  I don’t personally know a single person who’s been busted and spent jail time for marijuana possession but yet I see statistics that it happens all the time and weakens our civilization.

                  Telling a politician that his power grab ban won’t work has never stopped anyone from trying.

    2. I’m looking forward to the day when I can print belt-fed .50 cals and a Merlin engine for my printed P-51 mustang.

      -jcr

  5. Serious question – When will I be able to print a car?

    1. That would be illegal under the “Automotive Industry Protection Act of 2018” – so, in year or two.

    2. How about a woman who isn’t a pain in the ass.

    3. Along those lines, there are printers that use foundry sand, so you can print a mold for an engine block now.

      -jcr

  6. Mmm, I can’t wait to savor the tears of derpgressives.

  7. I just checked the prices on 3D printers. They’re only about $700 to $3,000. Holy shit, this will be a game-changer. Chinese manufacturing is in deep, deep trouble long-term.

    Unless they start making good 3D printers.

    1. But only for plastic parts. When I can 3D print things that integrate steel, plastic, aluminum, rubber, and copper, then I’ll get very excited.

      1. FTA, it sounds like that’s going to start next year. (Or probably a couple years, given the lead time.)

      2. The really cool shit is the 2-material stuff. Print with plastic and sintered metal, then heat to dissolve the plastic and get metal shapes you can’t get just from sintering. Also, you get all sorts of cool shit printed sensors from two conductors with different coefficients of expansion.

    2. I expect a good all-in-one, 3’x2’x2′ printer with 0.2mm resolution and 3D scanner-to-CAD file combination for $2000. By 2020, absent a world ecnomic collapse, I expect there to be a multi-material/multi-head printer/sinter/scanner for the same price.

      They are already kickstartering the cheap version of what I expect MakerBot to be selling next week. In fact, I think it will happen so soon, it will be unprofitable to start a Kinkos-of-3D-printing-scanning storefront business.

      1. Yeah, I wish I was smart enough to foresee what the exact economic consequences of this will be.

        In ten years, molecular printers may be a reality. It will be getting close a post-scarcity economy.

        1. One of the most interesting things to me is this sort of Diamond Age things where the shape of structures in channels from one chamber to another allow for some awesome multi-step high yield processes on small size- and time-scales. I proposed a similar thing to my advisor, essentially a fluid-bed reactor whose channels would do the same thing. He didn’t really get it, but the FBR with micrometer shape optimization would be bad-ass.

        2. I’m sure that if we start experiencing a shortage of scarcity, the government will step in to make up the shortfall.

        3. after that i will be my Star trek replicator??? i forget the name *googling*

          ah yes replicator! I thought it might have been called something different ^^

      2. Never underestimate human ingenuity. Or laziness.

        Kinko’s is still in business for a reason, despite the ready availability of printers, fax machines, scanners, and desktops.

  8. …toward the ultimate goal of rendering gun control laws a complete joke.

    3D-printer control laws, on the other hand, are just getting started, and there’s no right to print and bear 3D weapons mentioned in either the 1st or 2nd Amendment.

    1. 1A. Press… printing press.

      1. Silly Bot, don’t you know that “Press” refers to a protected class of sycophants who attend orange line circuit KOKTALE PARTIEEZ? It doesn’t refer to the act of disseminating information to a large audience using technology.

      2. If I remember my crypto cases, software might be considered to be protected by freedom of the press, especially if it’s distributed open-source. Similarly, maybe a 3d diagram of a firearm part would be protected info. Unless, of course, TEH NATIONAL SECURITY prevails.

        1. or for the children!

  9. It looks like it will stick to walls. That’s false advertising.

  10. If they’re going to make it that ugly they could at least do a bullpup design.

    1. You think the TAR-21 is ugly?

      1. Most bullpups are ugly. Not all, but most. The P90 is fucking elegant. But most bullpups are ugly.

      2. To answer your question, yes.

  11. “Better to scare the control freaks”?
    Hope this irony doesn’t reach the level of Nick’s on the post just above.
    The low-class folks reading this shit broke their teeth trying to gnaw on irony, and they won’t stands no more of it.

  12. Can’t wait for the day when some progressive gives all the glory to government for making the 3D printer possible.

  13. You can use readily-available hardware for at least some of the FCG
