[QUOTE=Trunk Monkay;39778923]You realize how a firearm works right? A fully plastic gun would melt or explode pretty damned quickly. Even if a 3D printer comes a long that can print firearms grade steel, it probably won't be as strong or as efficient as stamping or milling.[/QUOTE]
But 3D printers can be used to make machine tools for stampin and milling, which would otherwise be very expensive to make.
And suddenly 3D printers become illegal to possess without an extravagantly expensive license.
You know some idiot will demand they be banned or otherwise regulated because of 'muh children/muh safety/FOR MURRICA' at some point.
The video makes the gun sound way weird

Machine tools are VERY hard metals, so hard they'll shatter like glass, they have to be harder than the material they're cutting through.
Gun metal on the other hand is not especially hard (4140 alloy steel is common but there are many suitable alloys, the AR-15 upper and lower receiver is usually made of 7075-T6 aluminum, but the barrel will still be steel every time), it's tough but it's also flexible and that's why modern guns don't go kaboom.
Try to bend a drill bit and it'll snap, bend a gun barrel and it'll do just that, it may even spring back to it's original shape if you don't bend it beyond it's failure point too.
Cast or powered steel has a very poor internal structure for a gun barrel, it just will not hold up like forged steel does. Same goes for coldrolled steel, being worked cold damages the structure of the steel.

Maybe we can 3D print the machines that make the guns.
That would be fucking radical. A self-replicating gun-making machine.

They'll replicate and take over the world.
3d printers are pretty cool

I think if you did that, the result for each generation of printer would be like saving a jpg file under the lowest quality again, and again, and again.

I meant in the situation for lower resolution printers, mind you.
[QUOTE=Mon;39778125]the problem is the lower reciever carries the serial number, so it's the only part of the ar-15 that gets regulated as a firearm. the upper reciever and other parts are fairly easy to obtain, so you can imagine the consequences of this technology.[/QUOTE]
...not much. People have made the receiver of an AK47 by buying a parts kit and bending a shovel and afaik an influx of shovel-AKs isn't really a problem.

Couldn't one easily modify a 3D blueprint of a semi auto lower into a full auto lower?
[QUOTE=milkandcooki;39778818]I wonder if 3D printing firearms will become feasible for mass production in the future.
3D printing already has helped with making handtools from what I've seen, why not.. shoot-gun kill tools?[/QUOTE]
It could be handy for making even more plastic tat for Poundland to sell, and for Dr Stuart Ashens to burn with his blowtorch. Still, even if it is tat, it would probably be better than moulded plastic products, and there'd likely be a lot less sprue if they have 3D modelling experience.
Also 3D printing sure looks to be picking up.
What I want to see is an entire working gun made of 3D-printed parts,that would be interesting if it's possible.

[QUOTE=Lizzrd;39781267]Couldn't one easily modify a 3D blueprint of a semi auto lower into a full auto lower?[/QUOTE]
You'd still need a full auto trigger group but yeah, pretty much the only thing separating an AR-15 lower from an M16 lower is the AR-15 has more material in the slot the trigger group fits into, so a full auto/select fire group won't fit in there at all because it's too wide.
If you take out the extra material then it becomes a machine gun by law and while you can still [Url=http://www.atf.gov/forms/download/atf-f-5320-1.pdf]submit the paperwork[/Url] to the ATF they won't authorize it unless you're somebody special, like a member of Congress.
I wouldn't download a gun.
[QUOTE=Lizzrd;39781267]Couldn't one easily modify a 3D blueprint of a semi auto lower into a full auto lower?[/QUOTE]
yeah but if you can even find an auto trigger group for it, I highly doubt a plastic lower can withstand the stress of full auto.
I own a 3D printer that I made myself. And all I've done with it is print little trinkets and useful items... I must be a danger to everyone. I mean look at this thing, its clearly just a weapon in disguise!

Also calibrations are a bitch. I've been working 2 months now off-and-on on fixing this thing and improving quality and I still have issues (look at how the surface gets rougher as it goes up). It takes a lot of work to get a DIY or sub $2000 printer to work flawlessly. The only ones that work perfectly are industrial models that start at like 15 grand.

You're joking right?
A metric shitton of production companies are extremely interested in the future of 3d printing technology. 3d printing is becoming better and cheaper by the day, and a lot of production companies are hoping to someday adapt it.
Do you honestly think a capitalistic society is gonna want to ban this? This tech has the potential to overhaul and streamline production for an insane range of businesses. Better products being made faster equals more demand, and more demand equals more profit.
Banning it would be like shooting your own countries economy right in the foot.

They're called "rapid prototypers" for a reason- they remove or shorten an entire step in the manufacturing process. Instead of having to spend money on a prototyping company and then wait a few days or weeks for a prototype, it can all be done in house for a much lower cumulative cost and only the time it takes to print(no more than 12 hours on reasonable prints; 12 would be for a large or extremely detailed object).

Huh.
Alright, then.
[QUOTE=CodeMonkey3;39778058]This isn't a big deal. They made an AR lower receiver which doesn't take a ton of stress compared to the upper. People have literally made AR lowers out of wood and paper before.
I doubt it's possible to make a AR upper receiver with 3D printing.[/QUOTE]
This. This is almost the same as creating a stock or heatshield or that front post sight. Big deal, really.
If they recreate an entire gun that works more than once, then I'll be impressed, but I don't see that happening

You don't need to modify any blueprints to make an AR-15 fully automatic.
