back to article 3D printed guns: This time it's for real! Oh, wait – no, still crap

So, hype notwithstanding, it's now pretty well acknowledged that you cannot in fact make a useful gun out of plastic in a consumer-grade 3D printer. But wait! Hold everything! There's a new "Bullet That Could Make 3-D Printed Guns Practical Deadly Weapons"! Holy Cow! Oh dear. The ".314 Atlas" from designer Michael Crumling …

      It's not. If you had the right tools and steel, you could make a metal gun, as the article says.

      The whole "aarhgh this is terrible" angle to the concept of a 3D-printed plastic gun was that it wouldn't show up on x-rays at airports and suchlike, whereas a metal gun would. But if it was plasticy enough not to show up on an x-ray, it would also be useless as a gun.

        even making a basic black powder isn't that hard (although it is potentially quite dangerous especially if you start wanting to grind it for a faster burn).

        That said, even in the UK if you really want to buy a gun outside of the normal checks I suspect its not ridiculously hard - just very illegal.

            Hardly, at least not in the US. I bought a .303 over 20 years ago and had no problem then. It has only gotten easier, if more expensive since that time. I have looked into other vintage weapons as well and have seen pretty much the same.

            the 9mm cartridge the Sten used is still commonly available. Like the .22LR rimfire, there are different flavors, but you can still run your old school stuff off of ammo you bought today.

            "Buying a WW2 era souvenir might not be ridiculously difficult but getting the ammunition will be."

            You can tell that you're a Brit and don't know much about guns or ammo.

            Short answer, it depends on which gun you want to collect as a souvenir.

            A Browning BAR, depending on condition, will set you back $40K or more, plus you need to be able to own a Class III weapon. The ammo? .30-06 Same today as it was back in the 20s and is plentiful.

            If you want to purchase a Tommy Gun? Same thing. .45 ACP is available everywhere. Class III expensive to own.

            1911? Vintage is pretty cheap and again .45ACP.

            Of course if you're looking at a Japanese Rifle, I guess ammo would be hard to find, however you can always trim down your own brass and make your own lead bullets.

        For purposes of the current iterations of 3D printers, what you claim is true, but it is not universally true. When Taurus first introduced one of their lines of polymer pistols there was considerable concern that because so much of it was plastic, it would not be detected by the then standard detectors. I recall a number of solutions being proposed including impregnating the polymer with iron so it would show up. Ultimately Taurus made the barrel portion from steel and that calmed down law enforcement. What I don't recall if whether the decision to use steel was completely political or to what degree it made the engineering simpler.

          Guns do absolutely nothing by themselves, except rust.

          When a person holds one, the gun multiplies the striking power of that person. Note that people can still strike and cause harm without the gun. Also note that while gunless people vary quite a lot in striking power, those with guns are much more equal, hence the term "equalizer."

              It should be irrelevant because:

              a) he shouldn't be going into her bedroom.

              b) he shouldn't be wearing a ski-mask while doing so.

              c) upon seeing her pointing a cannon at his noggin, his reaction should be to freeze or retreat while identifying himself, thus eliminating the need for her to pull the trigger.

              Of course, in the case of my granny, there are no flat mates - grandad died decades ago, so anyone breaking into her home after dark should rightly be considered fair game. A bread knife won't help a 90 year old woman defend herself against a 16 stone steroid muching gym bunny hopped up on crack. Nor will karate classes. A small hand gun would do the job nicely.

              Alternatively, and I know it's a radical concept, we could just keep the scrote locked up after his 2nd burglary/assault/rape, rather than foist them once again upon an unwilling and largely defenceless community.

                Modern Tanks have fire suppression specifically to counter the opponent with a bottle full of flammable liquid.

                They also hunt in groups allowing each tank to observe the perimeter around the other tanks in the group making it hard to approach close enough to throw your bottle without being stopped.

                Egyptian protesters used petrol bombs to some effect against their own military but they didn't destroy the tanks but forced them back and its important to note that the Egyptian army did not have orders to use maximum force, if they had the demonstrators would never have got close the Tanks in the first place.

                So no having population armed with small arms isn't going to stop the US military imposing whatever the conspiracy theorists think the Federal Government want to impose.

      The Brits invented the STEN-gun. They dropped the drawings to occupied territory for "anyone" with basic machine tools to make up these guns, which actually worked when fired in anger, on real Germans.

      Those drawings are still around, probably. If all are lost, they can be worked out again. The Sten was designed to be cheap and easy to make from whatever was lying around in the scrap bin.

        Re: But against the backdrop of your British readership...

        And Americans liked the idea as well. They adopted a simple design of their own that became the M-3 SMG. Their main justifications were price and mass productions. At 1/10 the price of a Tommy Gun and easily made at stamping plants, it gave the troops a simple but useful arm for urban and forest combat. Later on, IIRC, they took the idea even further with a bare-bones pistol design: the original Liberator. It wasn't pretty or pretty accurate, but they were dead simple to use to the point each one came with pictorial instructions and can be dropped by the bushel to your favorite insurgent group out to topple America's Enemy of the Week.

          @Charles 9 Re: But against the backdrop of your British readership...

          The M-3 SMG aka 'grease gun' was meant as a machine gun of last resort.

          It was issued to Soldiers in the army who didn't carry a rifle as their primary weapon. E.g tank crews.

          Not very accurate, but something you could use if you had to bail from your tank. Cost to manufacture was around ~$1.25 - $1.50 (In 1940's dollars)

          There is really no comparison between the grease gun and the Tommy Gun.

      Yet again the myth that we British have no guns.

      Out in the British countryside we have plenty of legally held guns, mostly shotguns but quite a few rifles from .22 rat guns to scoped 30.06 Remingtons.

      On top of that there are the historical re-enactment societies with any number of highly serviceable weapons from muskets to Springfield rifles, and there are plenty of antique handguns which are quite legal if the ammunition is *theoretically* unavailable, such as Broomhandle Mausers and Navy Colts.

      As for the illegally held stuff, there are any amount, freely available if you know where to look.

Are you suggesting that once someone knows how something is made the urge to make stuff disappears.

Assuming the part is still stocked that is, even though spare part availablity is a big factor when buying expensive tools there always seems to be a few bespoke parts that are hard to find 10 years down the line.

        Anyway, a factory is well out of my price range to make stuff I want, so in the mean time while I'm waiting for 32 printing quality to improve/price to come down I'll continue to persue my hobbies by making things in a time consuming manner or using saved searches on ebay for spare parts as I do now.

          Obviously not. I think 3D printing will find a valid place in society sooner or later. But the conceptual limitations will make that place a small one. It is the job of strategy boutiques to de-emphasize these limitations in investors' minds, in order to secure more investment. Fair play to them. But I am not a strategist, I am an engineer. And I will not be investing at this point.

          Tinkering and hobbyism is great. Any hobbyist should buy and enjoy 3D printers to the fullest extent possible. For recreation and discovery. But not for business. Okay let me rephrase: 3D printing at home might be exciting, in the same way as building a cat's-whisker radio is. I was delighted with my cat's-whisker, and all my bread-board creations. But I never went around saying it is better than an iPhone and people should invest in my cat's whisker company.

          I have just forked out £22 for three plastic gazebo joints that prob. cost 10p each to manufacture. 3D printing would have had the tolerance for this, and finish doesn't matter. But it would probably not have had the strength or material properties. And as my gazebo is 10 years old, I was lucky to get the part, let alone a 3D printing data for it. And if I got the data or copied it illegally from another part, why should the owner give me that for free ? The design is valuable property, rightly protected by law. A gazebo joint might be a small, humble part, but somebody, somewhere put alot of engineering thought into it and somebody owns the design.

It makes a world of difference...

            This is why 3D printers were referred to as "Rapid Prototyping Machines" about 20 years ago when they were only really found in the R&D departments of various well funded and high tech companies. Sure, you couldn't make a useful part out of resin, but you could make a mold for the part, or a mock up of the part to fit to the rest of the machine just so you can get the spacing and tolerances right whilst waiting for the real thing to be ready.

    Plastic + Adhesive + Ceramic = Composite = Strength of Steel

    When they start increasing the resolution of the printers and allowing the mixing of ceramics with adhesives and plastics then we can start worrying: see http://www.sciencedaily.com/releases/2007/10/071004143114.htm

      Re: Plastic + Adhesive + Ceramic = Composite = Strength of Steel

      Commercial 3D printers can supply parts in a variety of materials including ceramic and metal. Their websites also detail the physical/mechanical properties - including manufacturing tolerances, which may be more of an issue.

      I wouldn't fancy firing such a weapon if the barrel was 'just a bit tight'.

      I'm not saying this makes the idea of a 3D printed gun any more viable. A blade of some sort is more likely. Non metallic, it could be built into something harmless using 3D's ability to make fully enclosed parts and broken out when required.

    Yes, Lewis, but...

    - Making a whole weapon using 'the right materials' takes lots of ability and very specialised knowledge and tools, and is really difficult and time consuming. Making only the barrel -from some standard tubing- and some other pieces -e.g firing pin and cartridge retainer and expeller- is orders of magnitude easier and needs very standard tools -a lathe,a press drill and an electric welding kit- which are in common use by many different kinds of hobbyists.

    - A non-rifled barrel makes it really difficult to hit something at more than twenty meters, but most shootings happen at far closer range. Agreed, none of these guns will be used for sniping, but at close range a shotgun type weapon is something to be taken very seriously.

    - These weapons are really difficult to track. The only way to do so would be through the marks in the rifling made by the lathe, and then comparing said marks with different lathes. But the lathe marks change over time, whenever the machine is adjusted and drills and other parts swapped.

      Re: Yes, Lewis, but...

      Sorry, that just doesn't wash. Anyone who really wants to create a weapon that works will not bother with a 3D print, they'll find a way of buying one that is less likely to main or kill the user as well, and everything else has already been done without a 3D printer. As for traceability, a weapon from a dodgy source will not point at you to start with.

      I have come round to liking these articles, though. They're a bit like those subtly changed online recipes for explosive things that will blow up when you try them, insofar that they are more likely to harm the idiot who tries them. I have no real problem with that.

      As far as I can tell, about the only weapons related thing you could usefully print is a grip...

    FWIW

    http://www.thefirearmblog.com/blog/2014/11/04/warfairy-charon-3d-printed-ar15-lower/

    A set of G-code files for a proper gun made from common stock materials would be far more meaningful than the plastic fantasy crap. CNC machine tools are in the same price range as plastic 3D printers.

    Good 3D printed guns (e.g. the sintered stainless steal 1911) are possible, but only as a stunt. Production costs and labor are ridiculously high relative to normal production processes.

      Yes, publishing a file for use with CNC mills and lathes is more of a threat, but I don't think that the home-priced mills are up to the accuracy required. So you'd need fairly pricy equipment; but the G-code files would reduce the skill needed.

        Excuse me while I fall off my perch laughing.

        To setup a CNC machine to make your bits takes a bit more than a G-code file and 5 mins bolting a chunk of metal to a machine bed.

        After all, installing windows is a matter of slapping the disc in the tray and pressing reboot.......

        But if your aim is to make a gun that can be fired once, then yes , it takes no skill to machine the parts and hope the act of firing does'nt blow your hand off, leaving your potential victim able to point and go 'ha ha'

        If your hope is to reuse said firearm after firing (and this includes still having a hand to hold it with), then you need some skill at machining stuff to be able to do it, whether or not you've got a G-code file

            Very few barrels are made in the U.K.

    3D printed "Gun"?

    The only bits the 3D printer made are the handle and case. What looks like a cartridge is, in fact, the barrel, with the bullet halfway inside. He's made a gun without a firing pin - which he went out and bought. There was a kid in my class at school, who used to fire rifle bullets from a vice, by hitting the percussion cap with a nail and hammer. Probably a lot safer, and more accurate.

    Zip Guns

    A good article. Yes, 3D Printers still can't print guns. Only the people who need to be shown the picture of a cartridge and told the copper part flies down the barrel ever seem to buy into this.

    For some reason, printing a gun is the peak-evil use task the mind comes up with. Like an atom-printer could make TNT, an atom-assembler could make Plutonium. Yet, the current 3-D printers have absolutely no functionality needed in making a gun. The only thing plastic on most guns are the grips. "Polymer" frame guns are popular, but they are made from some seriously high pressure injection moldings as strong as steel.

    However, The Big Picture -- can Joe Blow make a gun in his basement? Yes, has been able to for hundreds of years. These days it might be called a "Zip Gun", see Wikipedia. You just need a tube, some tube. You stick a cartridge in it, put a cap over the end. Hole in the cap, a nail into the hole. Big rubber band to pull back and hit the nail, fire the gun. You're done. Do anything that looks like rifling in the tube -- you're legal (in USA). Could even make them and sell them.

    Ah, but a 3D printer can make a frame with grips? No, too soft. Buy a cap pistol, use it. The cost a bit less than a 3D printer.

    Sooner or later, it'll happen. And I'm not worried.

    Look, let's face some facts here.

    Anyone with machining skills and supplies can build a gun. Not just "a" gun, mind you, not just a crappy zip-gun. Something along the lines of the UK's own Sten gun, or the Greasegun of my homeland.

    If it was good enough to arm front-line soldiers being sent to war against the Nazis and Imperial Japanese, it's definitely going to be overwhelming against your average street cop, especially as even very old firearm designs are fully able to take advancement of munitions development that has taken place in the intervening 70+ years. (Just so long as you respect the weapon pressure tolerances if you're thinking of using +P rounds. Or you can beef up the mechanism with sturdier metal.)

    And the thing about the Sten gun and weapons like it is that you don't need a complex armaments factory to build them, either. Or, indeed, a proper factory of any sort:

    Norwegian resistance fighters built Sten guns right under the noses of the Nazi regime.

    Danish resistance fighters did so, too, producing 200 in a bicycle repair shop alone, to say nothing of the other workshops, greater and smaller.

    Polish resistance fighters started building them on their own, again, right under the Nazi's noses, some of which were of superior design and construction to the ones actually being built in the UK.

    For an ironic twist, the Germans themselves manufactured about 28,000, though exactly why they did this is unclear, given that they had all the captured Sten guns they could ever want for espionage and false flag operations. Probably doesn't really count, though, since Mauser was making them.

    And more, too, it's a very easy gun to copy and modify, apparently. And yet, you don't often see criminal groups armed with hand-made submachineguns.

    That's why I'm not worried. All told, it's just too much hassle for crims to bother with. Will there come a day when you can simply manufacture a firearm in your own home? That day came 70+ years ago, bare minimum. Even with advances in desktop manufacturing technology and firearms technology, it's still going to be too much of a bother for most people who have malevolent intent at heart, even should miracletech like desktop nanofabrication or personal replicators come into being.

    (Also, if personal replicators or desktop nanofabbing come into being, then I would expect that medical science should have advanced to the point where being shot in the head isn't game over, greatly reducing the impact of persons of unkind intent being able to manufacture a gun in their own home. To say nothing of the fact that person of ill intent would need to think hard on the fact that if they can make a gun that easily, so can anyone else.)

      The big bug-a-boo isn't the idea of a homemade gun. It's the idea of a homemade NONMETALLIC gun. As in the untraceable zip gun that can get past metal detectors and such and be used to pull off assassinations from 10 meters or so with absolutely no way to tell you have it until it's too late. As in "shot heard around the world" import that can be considered an existential threat to any peace (or war)-loving country. As of present, there's no practical device capable of pulling this off at a standoff distance of at least ten meters, but this raises the prospect: not now, but down the road. Bows are too big to conceal at that distance and explosives too unpredictable at that distance.

    You don't even NEED a 3D printer for that!

    Honestly, printing a gun with a 3D printer isn't very creative. If you wanted to make a weapon using plastic then it's probably time to just come up with something other than "printing" a glock. There are far easier and cheaper ways to cause mayhem. A lot of which won't result in you personally getting hurt.
