they're engineers, making a 3d printed gun is one constriction, making a fully 3d printed gun with no metal parts is another entirely

>Making a gun with no metal parts
>Anything but a meme to piss off fearmongering normie antigunners
It's been done. Everything after the liberator that doesn't use normal fucking springs and a barrel liner is missing the fucking point.

A 20 shot rotary .22lr Nerf gun with a steel frame, barrel liners of 3/16" brake line, and a double action trigger set up in a SBR configuration with the option to print a buffer tube mount and take standard picattiny accessories is far more damaging and useful than a single shot hand remover

A 4 shot .38special/.380/32.acp pepperbox style Derringer using barrel liners and internal steel reenforcement is actually useful as a self defense weapon.

I fully realize nost engineers are straight up autists but defcad and other "groups" designing firearms need to start listening to their ideas guy or find one to add to the production team.

>that doesn't use normal fucking springs and a barrel liner is missing the fucking point.

there are plenty of 3d printed guns with barrel liners

if you think they're missing the point because your specific designed niche of gun isn't being produced for 3d printing, go make it yourself instead of being a faggot "ideas guy" and whining that the world isn't making exactly what you want, and that you decide what "the point" of 3d printing guns is

>Implying I'm not an Engineering student and 3D solidworks and mastercam designer
The hardest part of the liberator was designing the 3D printed springs (you can't print on most normie/hobbyist level printers). Simply to make a "ghost gun" to piss off antigunners across the world

But you right now, as a yurocuck let alone American can rely on the fact that customs isn't that good at their jobs and most firearm parts aren't regulated.

Etc. Should be the future of 3D (((ghost gun))) manufacturing.

Even warfairy fell into the
>Full 3D printing
Meme when his designs could have been entirely functional to the point of being better than a polymer lower via the simple addition of a few strips of steel reinforcement and a side plate or two to do the brunt of supporting trigger group pins.

But he had the good idea to release his a s t h e t i c as fuck stock design as a standalone for a normal lower, 80% or otherwise.

3D printing firearm design has petered out due to it's inherent lack of functionality and high intro cost.

But if you could buy a $800 3D printer and buy a $40 kit of metal bits on eBay and make an actual gun that could fire 200 rounds a range trip, hot fucking damn. And then load the file for the other 10 guns you're going to print that month?

I would very much like one.
Perhaps if one of you Americans could modify this existing design to do so in a safe and reliable manner. Do note that the design of the "Liberator Pepperbox" is not safe as it actually explodes when being fired. But I do suspect such incident are a result of people firing from a plastic barrel, printing it with the wrong material, wrong way, and, of course, the design itself.

>t. doesn't know fuckall about either

NFA stuff is still illegal under ITAR and won't be changing any time soon.

Tried it, 3d printed an inert mortar for testing. Used no.4 (?) .22 roofing blank seated in a spent .45 case for strength at the base. Shit was fucked, blew the end out of the pipe, need to use better material next time or maybe slower propellant. Tbh, best 3d printed weapon I've made on my printers has been a sabot and fin set for a 8in construction nail, used my air cannon to fire it at considerable speed. Interesting concept I need to improve on.

With my idea of integral interlocking metal within a 3D printed superstructure you could easily cut down on bulk and mass.

For us burgers a design using DA gp100 trigger components or plasma cut DAO basic 2 part self resetting trigger, with the plans to make those via sand casting for yuros and azyns, and a simple self self indexing rachet and pawl mechanism instead of the retarded webly semi auto inspired DAO triggers of (admittedly interesting and as a pure "can I do this" matter a technical marvel like the PATRICK... But trying to recreate the wheel) most 3D designs would make a gun that could actually shoot more than a few shots before kabooming

Pair that with being designed around nail gun charges or blanks (4-6 shot muzzle loading pepperbox) and a 20+round Nerf rapidfire style rotary "magazine" and a quick release(effective mag catch release) for swapping out cylinders would be a viable pdw a Euro could assemble from plumbing components, a few unregulated parts, sheet steel, etc. for peace of mind on a rainy day/muzzieocalipse

Try the same thing with a model cannon liner

Congratulations, you now have a mortar tube

What propelliant did you use and what was the burn rate/pressure curve? I mentioned bp or bp substitute because it's slow burning yet makes a lot of push. Rifle powder would probably be best if using standard reloading powder but anything smokeless could easily have you run into the peak pressure issue and rupture the powder chamber instead of filtering out the rocket cone

I used a nail gun blank, uncertain as to the specifics of burn rate and the like. In retrospect, my mortar design was probably wanting. However, despite destroying my tube, I will add that the 100% infill PLA I used stood up admirably. I probably need to use something like you've mentioned and have access to a cnc or lathe to make a sturdy insert for the shell.

Its always been legal to make your own guns. The case was whether you could distribute the plans as digital files that have the ability to pass over international borders via the internet. This was a free speech argument.

How could anyone think plastic shot will be as effective as lead shot? I suppose I know nothing about the industry so I don't know if we have strong enough plastic to compete or not. Either way, it isn't like lead itself is ever going to be outlawed.

as someone who made more then one handmade gun, I find it curious that people think 3d printing makes it a new or unique thing.

3d printing simplifies the production of homemade firearms. You know, small low-stress parts and whatnot.
The pure ABS/PLA pistols are just to stretch out the concept.

3d printers are cheaper than CNC machines, mills, lathes etc...and will be getting even cheaper in the future.

Isn't 3/16" too small?
>4 shot .38special/.380/32.acp
Only .380 is pretty common most places of those three, but it's still a lot for the gun to handle and not as common as other cartridges. Also how would a rimless cartridge work without drilling the liner or using some rim holder gizmo? A double barrel .22 revolver with 14 staggered chambers, 7 trigger pulls, would have .32 ACP power, low recoil/noise, maybe no barrel liners, and way more common ammo. Plus you could have rifled plastic barrels easily.

here's the magnet link. it is 307GB. Be warned it's from 2016 so it may not have too many seeders. Also it's FOSSCAD mega pack is version 4.7; the newest is 4.8.

Because what you just described comes down to
>.22lr harmonica gun the size of a large Nerf machinegun
>That lasts for a few shots

.38 is a low pressure cartridge and rimmed. Also has cowboy loads and can easily be loaded with a hand press. And fucking everywhere.

>Rifled barrels
Printed rifled barrels are only a thing due to legality(which I admittedly forgot about) they don't actually work

The old school "full plastic" way was you designed a gun that uses essentially disposable barrels that'll last one shot and then you pop a new fist sized barrel on your frame

We should be entering an age where complex pressure bearing components become production items. You could see a market where enterprising machining companies domestically and Chinese/Indian importers start selling/making barrels, chamber inserts, cylinders, etc. As well as stress bearing frame components and trigger components

Essentially the ability to "print" effectively a Ruger LCR due to buying an 80% sheet metal kit for the frame and trigger components with everything pre threaded and meant to lock together and sunk into a 3D printed shell. Barrel and cylinder both either common replacement firearm parts or a standardized part sold on Alibaba as a wink wink 5 way intake splitter and wink wink threaded rotary waterpipe

"Just press print" is a meme
But facilitating through designs based on standard diameter sheet steel, impossible to control parts, unregulated kits, sand casting, etc. is how the information age will kill gun control.

So a yurocuck can make a 5 shot muzzleloading smokeless powder revolver using .22 nail gun blanks and a 147gr 9mm hardcast lead projectile due to the difficulty of procuring ammo while an American will just make the same gun chambered in .38spl

magnet link is too large to post here's the pastebin for it.

>cap and ball using nail gun blanks
Fun fact: that approach + shoulder fired renders you immune to all the NFA's OAL, barrel length, and smooth/rifled restrictions; it's not a rifle or shotgun (and thus not an SBR/SBS) because it doesn't fire a "fixed cartridge" or "fixed shotgun shell", and not an AOW because the law specifically excludes
>weapons designed, made, or intended to be fired from the shoulder and not capable of firing fixed ammunition.

For this reason, I've been contemplating a homemade (metal, not 3dp) folding-stock pistol that would use a .25 nailgun blank to fire a #4 buckshot pellet through a .17 or .20 caliber barrel, as a holsterable pest control carbine. (Think USW, but single-shot -- at least, in the initial version.) Getting the chamber volume right will be key.

For detailed specs on nailgun cartridges, see EN 16264:
cuzzs.cz/userfiles/documents/Vyber_rizeni/0720013/Priloha_zarizeni_pro_zkousky_N1265 EN_16264_(E).pdf
Page 24 is particularly interesting, giving the peak pressures for various sizes of blanks at two different chamber volumes.
As for your mortar experiment, I don't have a clear picture of how much volume the initial chamber had (was it just the inside of the .45 case? or more like a normal mortar bomb with a sealing band half-way up, and lots of space between the fins?), but it sounds like maybe you needed to increase the volume to decrease the peak pressure. (Or maybe your pipe was just crap.)

Jow Forumsommandos in small confined shithole places can have guns now

Crazy idea time:
Instead of chamber inserts for a bullet. How about a steel cased rifle shell, neck cut off and under loaded with a slug. Think of the bullet it self as a cap lock, muzzle loaded single shot. The printed gun is a rack that holds a couple of them, a handle and hammer.

tldr; thick rifle shell + light pistol load
Like pic related only sleaker and multishot.

How is it anything like a harmonica gun?
>size of a large Nerf machinegun
Not even close, staggered chambers would let 14 fit in a cylinder 1.4-1.5" wide max.
>Also has cowboy loads and can easily be loaded with a hand press. And fucking everywhere.
Fair enough, but I'm thinking more about countries where firearms are more restricted, in South America or Asia for instance. I'm no expert but I'm pretty sure .38 isn't that common there, certainly not compared to .22.
>Printed rifled barrels are only a thing due to legality(which I admittedly forgot about) they don't actually work
Why wouldn't it work? It'd erode to shit fast of course but I don't see another problem with it.
>everything else you posted
You're assuming laws won't change as people try this stuff. That's why I don't want 3D printed guns to rely on that stuff, next thing you know some country bans it. Sure that's not the end of the world but if you're gonna make it why not make it available to anyone on earth?

Because you just described this but chambered in .22lr

Even the .22lr version of the liberator shits the bed after using it's thunder mugs (reference to early breech loading blackpowder cannons) too many times. You're talking an inch sidewalls worth of plastic per your 14 .22lr so yes it would require the size of a Nerf gun. Either multiple barrels and a rotary hammer mechanism on steroids or a rotary drum of preloaded barrels

>I never get the focus on "fully 3d printed" with these gun designers
For the sport of it. It's the dream of telling your replicator "gun, hand, semi-auto" and getting a pistol out of it.

>3d printed caliber adapters
my penis approves

I was thinking the steel abapters as a source of rifled barrels. But damn if you dont have a good point. Even if they where single shot and ejected in chunks would change the slamgun scene. Handfull of various calibers wraped the custom plastic 12 gauge shells. One cheap gun to rule all rounds scavenged. Mmmm, thats nice.

I'm honestly thinking about it, but regarding caliber conversions

I have a 7.62x45 VZ52 which is like $3 a round, but I can bubba it with a collar sleeve to use 7.62x39

Or... I could print out a whole build surface of case sleeves that do the same thing if I can be assed to design them to set individual bullets to the proper case length

You could do the same for 7.62x54r

Or .308 to .30-06

A printable way to cartridge conversion a rifle without needing to permanently modify or rechamber it.

I can't take a pic rn but I made a bold action .22 with scrap metal, lumber, a 1/8" pipe with a drilled out chamber, and a chep hardware store lock, powered by a spring when I was in high school. the 3d printed stuff is cool, but remember for single shot stuff you don't absolutely need it.

>inch sidewall
And yet the .380 doesn't even need that much. Sure the Liberator is single use but if the revolver blows up after reloading just switch it out to reload.
>50 shot
Massive 3D printed guns are incredibly impractical and niche, compact or bust.

Attached: lulz.jpg (300x168, 4K)

I think they should be printed in layers, laminated with epoxy and fiberglass sheets.

But the .380 liberator has a 50-50 chance of just kabooming and the .22 version will last maybe 3-10 shots per barrel with a thicker barrel same OD sidewalls.

A brake line line or a barrel blank/retrofitted chamber insert respectively would be entirely functional.

Besides having a printer, what would be some necessary tools to begin? Is there a particular durable plastic for this sort of construction that is dire?

I'm talking about the initial phase of creating a model, like a 3D editor that would be Open Source or at least free to use. I want to spend my time creating but where do I start?

I could try and make something hokey pokey and wing it on previous 3d designs, but what if I wanted to make a frame for a Glock frame or better yet a magazine?

Like this for example when building a firearm. We want to keep using a barrel, not have it break after 1 to 2 uses. How can the plastics be reinforced?

Solidworks is pretty good CAD software, used in some idustries; pretty sure they have a free version too.

Pirate solidworks. Essentially industry standard
They have a whole multi thousand dollar cert program for working in the industry but regarding just designing shit dicking around with it is the best teacher. And publicly available tutorials. I feel fucking old because I only have solidworks 2012. Pirate Bay or your site of choice should have a full rip of the software up to the most recent.

A 1 computer license will run you just shy of a grand but business licences can get ridiculous. As a private consumer you can get a license for about ~3-600 dollarydoos (or just pirate it). Honestly the widely available pirated copies as well as the free student edition of solidworks 20xx are a marketing tool to get more people trained in the program.

>AR FULL AUTO fire control group

Why's this a bad thing? Blacks wouldn't be able to do it, so I fail to see the problem.

because having a machine that can build a functioning gun in an evening without any metalworking is an anti-authoritarian dream.

I assume you can belt out a four winds shotgun in an evening as well, though, and that'll probably be more effective than a one shot pistol.

>price of a single axis manual mill

what is with people and investing so much time and energy into building and calibrating a 3D printer but won't DIY a single axis CNC machine from widely available kits and software?

Back in the day in "pre engineering" (highschool metal shop) we'd always fudge it and got away with aluminum and even steel milling by using autistically small steps like 1/128th of an inch. It'd take days to do something complex, but time wise 3D printing is equally if not more tedious.
