[QUOTE=catbarf;47407092]By people with the equipment, time, and know-how to do it. As opposed to literally anyone with a 3D printer, few hours, and Internet access. Which is exactly the point and I don't see why people don't seem to understand this. Yes, anyone can make a gun. Not everyone can make a gun easily and conveniently, let alone one which functions every bit as well as the 'real thing'.[/QUOTE] Any idiot can already go online and order virtually every part to make an untraceable gun. People hold build parties all over the country to get together and fabricate the last few parts and finish a gun. People on Youtube can show you how to use a Harbor Freight press and some sheet metal to make an AK lower. Plus, the gun laws in this country are so loose and the market is so saturated with guns that nobody [I]needs[/I] to 3d print one. Why bother when you can buy whatever you want, untracably, with cash, at the nearest gun show? Anyone in the country can probably get any (non-automatic) weapon they want in an afternoon. Hell, I wish America's criminals armed themselves with dumb 3d-printed guns. I'd feel a lot safer!
[QUOTE=Snoberry Tea;47407119]a several thousand dollar 3D printer.[/QUOTE] [QUOTE=Snoberry Tea;47407119]when they can just BUY a gun for 1/3 the cost or less of the 3D printer.[/QUOTE] If you find me articles hysterically saying the end is nigh then yeah, I'll call them stupid, but the point of most of these stories is that 3D printing is becoming cheaper and more accessible at an incredibly fast rate. You can get for $500 what would have cost $5000+ just ten years ago, so what is 3D printing going to be like in 2025? Nobody was terrified that Liberator-armed thugs would be causing carnage in the streets, but it's not a stretch to look at technological trends and wonder how gun control is going to work when anyone can afford a 3D printer and any 3D printer can produce a functional receiver.
Two pipes(one just a but bigger than the other in diameter), end cap, and a screw, congrats, you just built a shotgun. Why spend 500 on a shitty 3d printer, when I can make my own with ease due to the HUNDREDS of designs and schematics online... It's not hard to make them, and you can even make your own primers and powder easily. Guns are generally simple devices.

Those $500 printers are what you use to print little figurines and replacement parts. And gun control isn't going to work when anyone can print them, just like it doesn't work now, and TBH it's not going to be that big of a difference from now because anyone can get a gun now. Gunshows, armslist, straw purchases, gang affiliated dealers. There's no shortage of illegal guns available for people that aren't allowed to own them.
Revolution! Grab your arms! Ak 47s for everyone!

I read a great article once talking about how the genie is out of the bottle with firearms and we can't really truly get rid of them, with how easy it is to make them. And in the end, no matter what laws you make, criminals will have guns, they are already breaking the law, what's stopping them from breaking some gun control ones too? Edit: Not the original article bookmark I had (which 404ed) but pretty convinced this is the same article [url]http://www.davekopel.org/NRO/2001/A-World-Without-Guns.htm[/url] Remember that airguns are not really regulated across the US (with a couple exceptions) and the high power ones are used as hunting rifles.

[/QUOTE] gonna stop you there because that's fucking bullshit all hobbyist 3d printers are more or less the same things, with varying degrees of accuracy, build space, and extruder temperature ranges (which determines what material you can print in). How well a 3D printer is assembled and tuned by the user has much more of an impact than the initial cost. a skilled user can make their $500 home-built printer produce prints that are just as durable and accurate as a $2800 makerbot.

The groups and media that want to get rid of guns (a vocal minority) just make it SEEM like they are. No gun control will EVER make any difference in America. Not until you can remove, with 100% accuracy, every single firearm in the country, and then prevent further illegal imports of firearms, further illegal production of firearms, and further garage tinkerers from building their own. This is without the advent of 3D printing. It's a lost cause, and a cause that wasn't necessary to begin with.

The other 50% of the problem is whether or not the extruded media can withstand the forces inflicted upon it for firearm use reliably and the accuracy of the printer.

There are $500 printers withe 8x8x8 beds that are also big enough for the job. the forces inflicted upon an AR lower are pretty much negligable, all it contains is the magazine well and the trigger group, the bolt and the gas system is all in the upper. The nastiest shit the lower has to handle is holding onto the buffer tube, and the area which does that can be deliberately reinforced. also you do realize that these guys USED a cheap 3D printer actually designed to be a turnkey printer (one that comes pre-assembled and meant to be dead simple to use) right?

Welp I guess it's time to get a 3D Printer.
Lowers shouldn't even be considered firearms. Alone it can't do a D's damn thing short of being a club. I'll say Germany got it right with regulating the uppers, since that's the part that actually shoots. You can mage it shoot without a lower as well.

You would have people buying M-16 lowers and putting them on AR-15 uppers. 2) "Full Auto Capable" would mean all semi-automatics like AR-15s and such would be outright banned. Citizens revolt and another civil war starts. You need to re-think that.

On thompson stub machine guns the upper is considered the firearm. Hell you can by parts kits complete with the full auto lower and all. Same can be said about STENs. To make things more confusing modern guns like the SCAR 17 consider the upper the firearm as well. So reclassifying the upper on an AR as the firearm wouldn't really change how it's legally controlled, since it's still illegal as hell to build a full auto.

The reason AR pattern lowers are the FFL controlled part is because that's where the fire control group is housed. Yes, the upper is what actually fires the bullet, but the lower is what makes the upper fire it. Also the lower is what determines the kind of rifle it is, whether it's a civilian legal semi automatic or if it's a NFA fully automatic/burst
