Homemade guns: an exercise of liberty, or simply dangerous?
The Lamron ^ | 18 April, 2013 | Paul Michael

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 it’s 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 don’t require any sort of federal licensing or registration so long as you don’t 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 Distributed’s 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 doesn’t 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?

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.

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.

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.

IMHO...

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.

Wasn’t there some where in Texas you could go and make your own personal lower receiver?

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.

Or

Print the lower in wax and use the lost wax casting method

or

buy an 80% lower and finish yourself

or

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.)

Another reason why outlawing guns will not make anyone safer.
If people are to own guns, they should be of good quality, so they will be effective and safe to the user and innocent bystanders.

“I'd have to add the FN-FAL. It’s reliable, powerful, hi-cap.”

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.

“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.”

Ummmm...

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.

http://www.lasc.us/RangingShotBarrelMakingFeature.htm

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.

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.

You're wrong.

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.

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!
