Old news. 3d printing is basically the end of the gun grabber narrative, simply because it's a demonstration that they cannot actually control guns, therefore gun control is irrelevant.
They don't even have to be good, there's functional 3d printed pistols that can fire .38 special for upwards of 50 rounds without any barrel fractures, and that's more than enough to end the campaign. Not to mention that the US Army is actively working on creating 3d printed weapons to reduce equipment costs.

It's good news as far as I'm concerned.

parts of it like the bolt mag and trigger pack werent 3d printed. looks like a mix of real parts and 3d printed plastic

if haji made it op it doesnt even have to be 3d printed

>>34005263
The cost and access to 3D printing technology and materials, let alone the machining skills needed to then make a functioning automatic action from these parts far outweigh the costs of buying or sourcing illegal weapons imported from other european nations.

This is good news to you?

Yes.

Why was this shit meme ever contrived? It's not like milling machines were terribly expensive before. Jungle people in Vietnam were able to make simple blowback pistols with no knowledge of how guns work for the most part other than cloning other designs.

>>34005275
Listen cletus, maybe in the US you're free to buy all ammo you want but in yurop it's mostly banned. what will 3D printeds gun do when you can't feed it anything, exactly ? and don't say anything about reloading yourself, most of the materials needed to reload like primers and smokeless powder are also banned/heavily regulated.

They'll just try to regulate 3d printing or try and fail to regulate and restrict printing of 3d weapons. Maybe a blanket ban on any 3d printed firearms. That way no criminals will print 3d firearms. Because it is illegal and why would they break the law.

You literally cannot regulate 3D Printing. The most you could do to a pre-assembled kit is use a software/firmware restriction (which can be sidestepped pretty easy), or you just manufacture your own at home kit. IoT devices have made the necessary pieces of hardware easy as hell to get a hold of, plus some fucking washers, a soldering iron, and plastic, and you're GTG.

>>34005882

The difference is that you can't build your own photocopier, you can build your own 3D Printer. People were literally building their own homebrew printers some time before they entered the commercial market.

>>34006037
we're talking ghetto engineering here, if you want something reliable you might as well buy a gun from the black market

>>34006171
Not necessarily reliable, just practical. It would be entirely possible to make cartridges, but every time the discussion comes up here, people tend to vastly underestimate the difficulty.

Building most components to a gun is easy enough, but the hard parts, mainly the barrel and ammunition, are too often ignored entirely.

Can somebody PLEASE explain to me why 3D printed guns is such a scary new development? People have been jury rigging clandestine firearms for over a fucking century. Nobody has talked about mill and lathe control in all this time. Pic is a polish resistance submachine gun.

>Antoni Starsky built this in a cave! With a box of SCRAPS!

>>34006227

It's just a new technology, people get spooked easily and the media plays on these fears in order to get viewers. That's all. Also, that kind of stuff takes at least some rudimentary skill and a few investment in space and money.

A 3D Printer? Eh, not really. Not anymore than buying a decent AR-15.

>>34006227
Because a level of expertise, practice, and effort will always be required with a decent metal gun, at least for the foreseeable future. Mills, lathes, and the associated tooling are also fairly large and expensive, being industrial equipment with little consumer interest.

With plastic printers on the other hand, it's entirely possible that in the near future they will become quite widespread and commonplace, and the guns will need a bare minimum of expertise to print and assemble.

>tl;dr any dumb cunt can use a printer, you need to be at least not terrible to machine a metal gun.

>>34006273

I have seen the stuff they can print, it is literally as easy (to use something of comparable baseline knowledge) assembling a computer from just parts. It's stupid easy if you have a modicum of interest, and at least know how to follow instructions to find out what works and what doesn't. You won't have to spend hundreds of hours getting decent enough with a 3D Printer to figure out how to assemble the device, download the software & files, print it, and then assemble that. There might be some trial and error involved, but it's just fuckin' plastic. Reprint it, sand it down, and try again.

The concern for them in the US is whole "ghost gun" thing, where you can just print out a gun - pop a few shots off, and then ditch it without anyone ever finding out where it came from or who did it. You can sort of do this already (looking at you nigs and bikers), but that's hard to get into if you can't pass. This even sidesteps the whole private sale rule, because with those there's still presumably a paper trail (from where the gun originally came from) or someone will speak up. It's all about obfuscation. ATF/NSA/LEO don't want snackbars capable of printing out guns to go with their bombs. And they don't want spree shooters able to do the same. LEO/ATF/NSA could give a fuck about bikers and nogs shooting one another. They keep their violence insular for the most part, and when they don't, they crack down hard. Hell, in Chicago, killing a civilian is so looked down on and multiple gangs will try and kill the guy who killed someone he wasn't supposed to because of the heat his resulting stupidity is going to bring on them. His own gang might even just kill him to keep him from flipping on them.

Abroad the concern is more about the ability to get guns cheap and easily in general, which admittedly, those governments don't want whatsoever.

-All ammo purchases must be done through a licensed ammo vendor

-No selling ammo without going though a licensed vendor

-No bringing ammo yourself across state lines

-No purchasing ammo online unless first received by a licensed vendor

Beginning the January 1st 2019:

-Licensed ammo vendors will be required to record, maintain, and report to DOJ records of ammunition sales, in a manner similar to dealer’s records of sales (DROS) for firearms purchases.

-Background checks required to purchase ammo

>>34006227
all the previous answers are off-base. It's a "scary new development" because anti gunners are fucking STUPID and don't know that you can even make guns at home. Or how guns or anything mechanical works at all. 3d printing is evil magic voodoo to them because they were completely unaware of previous home manufacturing.

Speaking of loopholes, all the separate components for reloading ammunition is technically okay to own in Australia, because the brass and bullets are just metal, and the primers and smokeless powder isn't covered under firearms laws, but industrial safety laws, because it's used in other shit like mining, hobby rocketry, etc.

So you can legally own the components, and reloading equipment without a firearms licence, but you're not allowed to assemble them.

The possibilities are intriguing, really...

Frankly, accelerating pretty much anything to supersonic speeds is fun shit. If we're talking about having to do it because of a conflict, that's another story, but I'm talking specifically about the feasibility of manufacturing, not the use itself.

People have this odd mental disconnect where they think firearms are magical or some shit. People have been manufacturing them for hundreds of years without any of the modern knowledge, tools or techniques we have today. They didn't know shit about metallurgy, they just made it big enough that it wouldn't explode. While it isn't optimal, that methodology is still completely viable today.

It appears to be a .22 caliber gun that feeds from a Ruger 10/22 magazine, so it's not far from an old Intratec Tec22 or something.

You could easily 3D print a little machinegun or something for .22LR, it's a light caliber, the gun is gonna wear down pretty fast because 3D printing spool plastic is generally pretty weak stuff, but it'll work.

The problem with that is that liberals don't actually care if their laws work, they feel the need to meddle.
Doing something, even if it's useless or even harmful, will always be better than doing nothing to most of them.

>>34006985
Absolutely. There are printers that can be had for 100, even.

Costs will vary depending on what your requirements are. If you're only going to print in PLA, then you don't need a heated platform and the nozzle won't need to get nearly as high temperature as if you were printed polycarbonate, for instance. That alone will save you a lot of money.

Whether your printers uses ACME rods, belt drives, etc for interpolation will greatly affect the price, but also print quality.

The larger the print volume, the higher the cost.

>>34006879
Just did a shitty diagram of a pump-action marble/ball bearing gun.

Basically, the slide loads the ball into the chamber, as well as pushing the piston back.
The piston squirts some alcohol from a container in the pistol grip, compresses it with air into the firing chamber.
When you release the slide, the pressure from compressing the mixture pushes the piston forward, which pushes the ball against a seal in the barrel, but doesn't have enough pressure to push the ball past the seal.
Pulling the trigger ignites the mixture in the firing chamber, which pushes the piston forward with enough force that the ball shoots past the seal into the barrel.

>>34005630
>most of the materials needed to reload like primers and smokeless powder are also banned/heavily regulated.

You could make what you need. You don't need smokeless powder. Black powder is sufficient to run simple blowback actions, and you can make your own black powder with your piss (nitre bed) and wood ash. Primers are trickier, but you can make a paste of Armstrong's mixture, and that should do it (but it is quite a bit more dangerous).

By far the trickiest part would be cases, but you can do that on a lathe.

3d printing has absolutely no potential for large underground manufacturing. The machines that can reliably print in sufficient quality cost more than crate of Aks. also, printing takes a buttload of time. and way more skill than just machining a gun in some garage.

It's once more people overreacting to something they have no understanding of.

>>34007567
>engineered ignorance
FYI, what you describe there is an actual thing but the correct term is learned helplessness.

>>34007981
Quality doesn't mean shit when your gun cost 30 cents to make. We're not talking about anything being used in warfare, this shit is going to be used to rob a corner store then dropped in a gutter. 3d printers are more than adequate to produce weapons for that.
Imagine this, you print out a hundred .38 Special single-shot Songbirds, and you sell them to hood rats for $50 each. Hell, $20 each. For an initial investment of $400 or less.

I really have trouble phrasing this, but it's like an ultimatum. "You can't stop us no matter what you do, so fuck off and leave us be". The point is Gun Control is simply obsolete.

>>34008077
This, the kind of gun you're looking at for criminal mass production is something that'll at best last 50rds and that's if it's ever shot that much (it won't be).

Think some kind of three round double-action pepperbox with steel liners in the chambers and a folding grip, .38 caliber or so, it's not made for precision or fighting, it's not made to last, it's made to shoot a few times, it's probably not even rifled.

>>34008077
The gun in opening picture probably took 15-30 hours to print, and it's probably just casing an possibly trigger mechanism. materials would have cost anything from 5 dollars up. and the important pits are metal. it would have been much easier and faster to make by hand. and if you try to actually print a gun barrel... well good luck.

>>34008151
The Songbird pistol is already stress tested firing .38 Special with no issues without any Barrel Insert. You're living in 2008 still, the guy who designed the Songbird has moved up and is trying to get it to fire .357 already, and he's been mostly successful. If he actually used a Barrel insert, he'd have it firing .357 with no issues. This stuff isn't hypothetical, it's already been done.

>>34008456
>They just aren't that accurate

Which is completely, totally irrelevant. These weapons are disposable, untraceable, unscannable, and unbannable. Completely impossible to regulate, and they can kill you just as dead as a factory made firearm. You seem to have it in your head that they're going to be used for target shooting, they aren't.

Accuracy and reliability are completely irrelevant. They work. They're enough to commit crime with. Any hood rat can get one at any time and nobody could even hope to stop them. Gun Control no longer has a leg to stand on, end of story. That's the point.

Wewlad, there's this new invention called 'The Leatherman'. Most people are already carrying a set of pliers with them. Along with screwdrivers, an awl, a knife, a couple files...

>>34008611
you go down to fucking Office Max or order from Amazon a commercial 3D printer
then you download the files for a gun
then you print it
then you assemble it
then you rob the liquor store

What volume would you need a 3d printer to be to print a gun?

>>34008611
>>34005585
why are you arguing about the cost? It was NEVER about the cost, it's about telling the government to fuck off. You're pulling economics out of your ass for something that was not intended to be economical

>>34005263
That's a Ruger 10/22 receiver and functioning parts with a 38 printed stock and barrel shroud.

>>34008621
Or you just rob it with a knife and they still five you all the shit.

>>34005630
Match heads you dunce Grind em up and use them as propellant and ignition.

>>34009055
Larger is better, but you can print it in multiple pieces and then bind then together. Depending on the method you use, the adhesive might actually be stronger than the rest of the print, lol.

>>34009386
... bind them* together...

>>34006429
Ghost guns are a meme. I could throw together a slamfire 12g with two pipes and a nail, for fucks sake.

show me a 3d printed gun that I would rather use than a 12 gauge slamfire pipe shotgun. Protip: you cant

I want a game show where they release a handful of survivalists/machinists and shit into home depo with a 2 hour time limit and see what guns they can make. No power tools allowed besides a drill press to mill the barrel. This would actually be entertaining with different kinds of weapon categories as well or explosives.

i'd take one of these over a slam bang, i'd totally watch that show though. like junkyard wars ameribros edition.

>>34012087
junkyard wars was exactly what I had in mind

>>34009055
I checked some files from the liberator pistol. The frame seemed the biggest, it was 131x82x41mm

>>34006663
It's pretty easy to empirically determine shrinkage for your exact conditions. Basically

>Measure it before and after casting
>before size / after size is the scale factor you multiply your dimensions by to get a finished casting to size

>>34014658
Why bother?

You would be machining all important surfaces anyhow

Matches work amazingly too. Even can rig up a primer with the striker paper stuff.

After seeing this I realized how easy it would be to make. Pressures are so low it's actually pretty safe as long as you don't do something dumb like capping both ends of the barrel.

>>34014680
yeah, that's basically what's inside a cap gun primer, though I'm not sure how cost-effective it would be to make Armstrong mix from matches as opposed to the other alternative

>>34005263
Parts of it may be printed. You obviously don't want 3d printed barrel etc.

There's nothing wrong in 3d printed stock or fire control group though, other processes may lead to more reliable parts that are more economical when produced in mass scale, but it'll do.

>>34006227
Ease of construction. To make a gun on your own you have to go get parts and be able to put them together, requiring some tools. With 3D printers anyone with one can just download the file(s) for the parts and put it together with much less effort

>>34015602
Eh, I've seen people having trouble even with test 3d prints ... Having to fiddle with belt tension, blowers and other shit after hours of printing.
People scared of that shit think it's like a laser printer where you get instant results instead of reality where it takes hours to print a small autism spinner lmao.

>>34007294

Is grade school out already?

>>34008077
You don't get it. 3d printing is a dead end for guns.

Anybody can make slam-bang shotguns with less than 20$ in materials and an hour of time.

There is no economy with 3d printing, you couldn't print anything useable to sell for 50$ and still make minimum wage.

>>34016022
Glad to see you're contributing to the discussion.

A prusa costs around 400 euros and can use many kinds of plastics.

Its easy to assemble, easy to maintain, easy to use and easy to expand.

2 years ago it was 600 euros if you wanted to mount it yourself, today they sell them at 400 already mounted and calibrated.

So, yes retarded post.

>>34016043
>3d printing is a dead end for guns.
Wrong, it makes toolroom prototypes miles easier.

Working guns though? That's really limited use.

>>34016072
That's more like it.

People tend to forget 3d printing is meant for quick prototyping, not mass production

>>34008611

For around 600 bucks you can get all of that.

400 for the prusa
100 for being a useless fuck using the prusa and fucking things up while making adjusting the thing(its not complicated... just requires a lot of time and trial and error so skip this if you really know what you are doing)
60-80 bucks for the plastic(there are many plastics to choose from, from nylon to ABS to carbon fiber.

5 for something like a firing pin
10 for a recoil spring
Ammo for whatever price people buy .22 or .38 in the US.

So, we have the materials for the body, the firing group, the bolt and if you really want to do it get a barrel or do the rifling yourself from a piece of metal.

Either way, is not rocket science and is nothing that will trigger any alphabet agency atention since springs are inoffensive, firing pins aren't hard to come by and a barrel is optional, so unless they are putting under a watchlist everyone that uses a 3d printer, yes they can.

The real hard part of a 3d printer is time, because holy shit the thing is sensible to even a breeze and takes a effort to make it reliably work.

>>34016206
I think that maybe in a couple of decades the technology could be used for *some* mass production.
