no not really. your pic is pretty much liberator-tier. 3d printing isonly good for making models and prototypes at the moment. maybe you can try making stock if you like shitty plastic stocks.

of course its only if we are talking about current and up coming tech, not some crazy plasma-3d casting steel or something

>>519545

What about prototypes like this?

>>519546

yeah its cool but material is too weak and it will get catastrophically fucked after a while.

At home you can't print the most important parts of a firearm that are also the hardest to make. 3D printing might be part of the firearm industry, but only for very specific purposes that are too expensive for the average man. Like this:

But for something sci-fi, how about this idea?

>use the tech from vid related, just make it a lot stronker

>fill the work area with some inert gas that is good for this kind of thing

>use magnetic force to shoor in a ball of melted metal

>use the soundwaves to form it into the desired shape

>then the waves put it down to a conveyor that brings it out of a machine, just like how a CNC machine does it

This way you'd only use as much material as you need, so you could save a few pennies for every part you make this way. But it only adds up if you produce them by the millions. Of course you wouldn't have to worry about drill bits and similar parts wearing out, so that's some more money you save on the long run. But I don't think that you could make any parts with holes in them, so you could only make things like triggers and connecting bars. Of course you could drill holes at them after this machine gave them the basic shape. An other problem I see is that you might have to find a way to cool it down quickly, otherwise this process will be too slow for mass production.

Im sure he lied with "delete all source files".

Also, I found another prototype.

It depends on the design, filament, and the printer. Some printers are hot garbage, some filament just isn't sturdy, and you need a design that isn't too small and thin or stupidly upscaled.

If your shape and design is within reason - see >>519550 - it's possible to make it work. But it's the same with using plumbing pipe and scrap metal in that you need to know exactly what you're doing or you'll just fuck up days of work.

>>519571

Doesn't that image not work?

Excellent for producing non pressure wearing parts.

For everything else, you'll need a lathe and mill at minimum.

>>519692

What did you use to unpack everything? Archive manager is giving me the finger.

>>519894

>using GNOME

Desktop environment elitism aside, here's how I did it.

<open terminal

>sudo apt-get install p7zip-full

<cd to bmp file

>7z x Liberator.bmp

Thanks m8

thinking about switching to manjaro w/ i3, thoughts? using poobuntu now

>>519543

Main problem with 3d guns is that nearly no one is seriously doing what needs to be done: design guns parts accounting for the constraints of the material used instead of trying to c/c existing designs because the exterior of the gun is easy to 3D print.

>>519543

being this shit was years ago, we're in the future now, so look around I guess.

>>520658

probably because designing them around the constraints of the material instead of making stronger material would result in fuckhueg guns. Think 20mm sized rifle firing a 5.56

Overall I'd say they are largely useless but we should keep developing them for the sole purpose of causing politicians to wet their beds.

3d printing is at it's best when you mix it with parts made of other materials ("vitamins", to borrow reprap's terminology).

Even OP's Liberator design had to include a steel nail to actually work.

>>520679

>probably because designing them around the constraints of the material instead of making stronger material would result in fuckhueg guns.

Yeah but if you could print a fairly reliable Barret size semi auto rifle in 5.56 that would still be a major achievement. Since you would only use polymer even fuck hueg guns wouldn't be that heavy and still usable.

>>520681

Like this version?

>>520730

This one's not very good example, but it still performed better than vanilla Liberator, IIRC.

>>520681

And a metal weight because the NRA was always quislings.

>>520681

>Even OP's Liberator design had to include a steel nail to actually work.

It did not have to. It would have been illegal without the nail but it did not have to have a metal firing pin.

>>520134

I don't know. I use Debian and that's all I've ever used. I'm new to loonix. I do like i3 though.

>>520942

To make it legal it has metal weight inside the handle >>520925

Plastic firing pin was too unreliable.

>>519543

>What you thinks about the 3D printing weapons

RIght now it's ok for rapid prototyping some things and a litmus test on who has a ban happy gun grabbing tendencies. If a hypothetical scenario happens where you need to crank out firearms production as much and as fast as possible. It probably won't be done by current 3d printing tech.

>is there future for those things?

Sure, if it's not smothered to death by those who fears it's full potential.

>>520134

Typing this on a machine using Manjaro XFCE. I have another machine with a 16.04 LTS nogbuntu based distro XFCE as well. Manjaro is on an older machine that does not seem to like 16.04 buntu for whatever reason. The package manager on Manjaro is pretty good, I can see why Archfags likes the AUR.

>How much more R&D would be needed before it can print wood and steel?

Already being done, however the wood 3D printers creates can best be described as "made of sawdust". All 3D printed material in fact has this problem of not coming out right, metal is much more expensive in terms of equipment if you don't want shit quality on top of it.

The real value for a 3D printer in your workshop is being able to breakdown materials then reconstruct them into different materials once it's both affordable and more feasible in having assured quality. I have some plans to try out purifying toxic sludge at some point.

>>523755

You'd need to use one of those paintball aircanisters. A little disposable one does not have the power.

A benchtop lathe is infinitely more useful, and as far as I'm aware also cheaper than current 3D printers.

>>519543

Not directly 3D printing weapons, but rather 3D printing tools designed to make the critical parts of specific firearms and then 3D printing the non-critical parts

You could make the Luty SMG better while being even simpler to manufacture if you incorporated 3D printed parts and designed it with the intention of being made using 3D printed jiggs.

>>519894

if you mean for liberator, i got it as a torrent. check the interwebz for it again

>>523775

Then I can't conceal carry, though that may be good for home defense. I could make a derringer though which could expend all the gas to fire

>>523776

Show me where you can get a lathe that's 200-400 bucks. Because you can get a 3dprinter kit around that range. And no micro lathes don't count because they're shit.

>>523886

Unless your doing barrels skip the lathe and go for a small mill, $800-1000 and you can make damn near any gun parts you want.

I have a 3d printer one of the $400 range. Its neat to mess around with and i want to try to print some 37mm shells for my flare launcher, but other wise its damn near useless for firearms.

>>523907

All ya need for a lathe doing barrels is making a straight hole and turning it down to size. You can use a button to make the rifling with a jury rigged shop press from a bottle jack and scrap metal. The hard part is making the rifling button but there are folks on ebay that sell them for about 50-60 bucks.

>>519546

>destroyed the source files

It's a fucking airsoft gun, you didn't create a weapon to surpass metal gear. What a fucking weenie.

>>524131

I bet he lied.
