Skip to comments.Homemade guns: an exercise of liberty, or simply dangerous?
Posted on 04/18/2013 3:53:07 PM PDT by marktwain
Prompted by the horrific Sandy Hook shooting last December, lawmakers across the country are locked in debate over the future of gun control in America. While they fight in Washington over background checks, there has been a technological revolution brewing. In the face of increased gun control, several groups have taken the initiative to manufacture guns via 3D printers.
A homemade gun sounds revolutionary to most, but its perfectly legal so long as it meets federal and state restrictions on gun ownership. That said, $30 and a simple YouTube tutorial can land you a homemade shotgun. For the more aesthetically minded, gun parts can be bought separately and modified at home to produce a fully functional AR-15. Homemade guns dont require any sort of federal licensing or registration so long as you dont plan to sell them.
The Wiki Weapon project began last June with the public reveal of Defense Distributed, the goal being to design gun parts that can be accessed and produced by anyone with a 3D printer. There are still several hurdles in the way of Defense Distributeds goal, however. First and foremost is the Undetectable Firearms Act of 1988, which bans the production and ownership of guns that can go unnoticed through metal detectors.
The law is set to expire this December unless lawmakers should choose to renew it, and with the current state of the gun control debate it doesnt seem all too unlikely. The current cost of 3D printers is another concern with some of the cheapest models still pricing well over $900. Most concerning, however, is the overall quality of these guns. The materials used by 3D printers are hardly as durable as metallic parts already on the market.

Wasn’t there some where in Texas you could go and make your own personal lower receiver?
Want to get even simpler.
We have a right to them for self-defense against the criminals who use them.
I’d like to see a gun shop rent out a 3-D printer.
I wonder if one can go to Kinko’s yet and print a gun.
Scan the lower for the AR-15.
Print it, using a 3D material with a low melting point.
Make a cast of this lower
Now, make some really nearly perfect castings of the AR-15 lowers using some nice quality steel from bumpers, leaf springs and scrap metal from a local junk yard.
Or, just go buy a nice lower for ~$150-250 and build that AR-15 up over time. The beautiful thing about this weapon is that it’s highly reliable, and it’s customizable to the point that you can make it shoot almost any round on the market.
The only other weapon that comes close (or maybe beats it) is the good old Ruger 10/22. I still kick myself for passing on that rifle when it came out in the early 80’s. Never saw it as a worthwhile gun; thought it was a waste of $79 back then. Boy, I blew that one.
The 3D printing material is really expensive. I don’t believe you can re-cycle the wasted powder (I may be wrong), and you only get a fraction of the material actually used to create the weapon.
But, the stuff runs around $10-50/lb To fill a tray of material to make a single lower you are probably talking around 5 lbs or so. And this stuff is not nearly as strong as the weakest metal.
Haha, liberals are about to find out that their dreams of “Gun Control” will soon enough be quite obviously a practical impossibly unless they want to reduce us all to stone age technology. By prohibiting information and and advances.
I’d say government schools are taking us pretty far along that path as it is.
Shotgun shell fits in 3/4” water pipe.
Use your imagination.
The 10/22 was introduced around 1965 not in the 80’s.
I don’t think that will nessary. Right now they would be better off renting uses of their equipment with themselves as “consultants”.
That being said just sinficantly rise the cost of guns and your going to wipe out gun ownership anyway.
So were going to have to wait for the cost of theses printers to come down, or form a underground gun market in the states in question.
I’d have to add the FN-FAL. It’s reliable, powerful, hi-cap.
“Id say government schools are taking us pretty far along that path as it is.”
Funny but sadly true, Our Government run schools are so obsessed with leftist indoctrination and funding the Democratic party by way of obsessive numbers of useless union employees that they aren’t bothering to educate our children anymore.
There are a few errors in the piece, and many articles about 3D printers have perpetuated some exaggerations and myths. I did custom machining for a living for a few years a long time ago, just before such work was, for the most part, reestablished in other countries with foreign slaves. Articles about CNC work and robotics also tend to keep some exaggerations going for the purpose of getting more customers to sign their lives away and become buried in debts.
Before buying a 3D printer, learn more about its limitations by studying traditional machining methods for a part or product that you’ve considered making. And study the likelihoods and doubts concerning market demands very thoroughly.
Didn’t most people back in 1791 make their own guns?
3D printing is not necessary for men who seek a couch alternative.
Men can just learn how to use a lathe and a few tools, buy them used and set up shop somewhere making homemade “hydraulic cylinders”.
A little brains and elbow grease.
And a hammer and punch...Oh wait
Just got a 3D printer in at work.. so far it’s been pretty awesome but the printer was $50k along with the S/W package so not your local home printer.
IIRC, there's a TechShop near Austin now. That's a membership-only place, though, but they do advertise having a 4-axis CNC mill.
There might be a policy against gun work there, too - you should probably check. It might be cheaper to buy an "80%" receiver and the required drill jigs and other related bits and tools, and a cheap tabletop milling machine from Harbor Freight.
You can order an 80% complete lower and then finish it yourself with a bench top drill press and a jig.
Print the lower in wax and use the lost wax casting method
buy an 80% lower and finish yourself
download the plans for the “lego lower”, mill out the plates and assemble
Will not happen. Imagine the liability lawsuits when poorly made guns blow up in the operator's face. Gun shops don't need the lawsuits. And printer companies will cringe if their printers are purposed solely for gun making. However, one can use a 3-D printer to make a home-built 3-D printer, getting around limitations on renting it! (Easier just to get a real gun.)
Love them. If the lower were the legal receiver like the AR making upper changes cheaper it would be about perfect. A heavy barrel model in .243 with a big scope would be a coyotes nightmare.
P.S. Notice as the AR improves it gets more like the FN FAL? (piston action etc.)
This technology only enables one to acquire something more effective.
“Now, make some really nearly perfect castings of the AR-15 lowers using some nice quality steel from bumpers, leaf springs and scrap metal from a local junk yard.”
Casting aluminum is fairly easy. Casting steel is a whole ‘nuther matter!
“Nearly perfect” doesn’t quite get it. You must get the tolerances correct. You need to allow for shrinkage when 3D printing your mold, etc.
Even if you do make a good lower receiver, the barrel, upper receiver and bolt are critical and difficult to make.
Making a home made single shot smooth bore to fire a rifle cartridge is not too difficult. Making a home made AR-15/M-16 is quite different.
i still don’t know anyone who wants to get shot by a .22.
maybe the stock, but there were standard arms makers and making the metal parts most people couldn’t do on their own.
Really? I saw my first one in SDak at a small town sporting goods store the first year of my college career. I remember seeing it for $79 and thought “What a rip off ... cheap plastic magazine won’t last 30 minutes”. That was 1980.
That Ruger was really introduced 15 years earlier!?
It’s perhaps the most customizable rifle ever made!! Still kicking myself for not buying one then.
Wouldn't be the first time, promise it won't be the last.
I was reading that the earlier generations were concerned about the material being contaminated and not dispensing through the printheads if recycled - causing the printheads to clog.
Guess they fixed that problem.
Hey, that file on your flash drive is a felony.
It’s coming.....at least they will try. Total control is all they are after.
F em all.
Good luck identified the file.
Encrypt your drives using software like truecrypt.
If you do it right there will be no way for them to know what it is you have, not that it is any of their business.
Well yeah, but most people bought the parts (like from blacksmiths, etc.) and assembled their own weapons.
yeah, they all needed them for defense of one kind or another.
Steel for an AR lower? Something new every day.
I was wrong on that date. It was introduced in 1964. It was the little brother to the Ruger 44 Carbine that came out in 1959.
Here’s a guy who made a gun from a shovel: http://www.northeastshooters.com/vbulletin/build-yourself/179192-diy-shovel-ak-photo-tsunami-warning.html
No printer needed :)
Or a crook uses one to mug somebody and the somebody finds out and sues Kinko’s.
Whoever put me on this “3-D Printer Ping!” list, please take me off. I’ve had to use these stereolith systems for he past 15 years. Being on this list is too much like being at work. Please take me off your ping list.
Ar-15 and M-16 lowers are made from aluminum. Much easier to cast that steel.
You are soooooo outta here! (BTW youse guys hiring?)
LOL. Perhaps I was little harsh...
Yes, the early materials were somewhat to very expensive.
Yes, many of them are still difficult to recycle.
But today you can make serviceable filament from discarded soda bottles. There’s even a guy selling a bench-top shredder and extruder for that purpose.
Today the pallet of available materials is vast and the processes allow considerable variations in feedstock. One could tune their machine to make serviceable lost wax masters from ordinary paraffin or bee’s wax instead of the specialty waxes formulated for jewelery use.
Sintered powder machines can recycle all the unsintered material, with the only caveat being that the must be sieved to remove any damaged or stuck together grains. (and that you have to be careful to not mix differing formulations.
Like any other technology costs drop with experience and volume. You need to run as fast as you can just to stay caught up!
Right now? An opportunity to improve upon the existing technologies in both the RP and ordnance fields.
