3 D PRINTING OF MACHNINE GUN

BLAZE TV SHOW ^

[Manta]

Glen Beck has guest who has and is able to print AR-15 like machine gun. Video has link to youtube vid of weapon in use

[cuban leaf]

Every video I’ve seen on this shows only some PARTS of the gun can be printed. And the barrel and firing pin are not among them.

[timlilje]

Please don’t fall into the trap of calling a semiautomatic weapon a Machine Gun.

[MrB]

Barrels and firing pins are not controlled items, though...

[Manta]

3D printers can print with titanium now

[ButThreeLeftsDo]

Machnine. Is that like a Tec-9?

[Manta]

Watch the video. Cody shoots semi auto then full auto. Unless he has a very very fast trigger pull

[Brooklyn Attitude]

“3D printers can print with titanium now”

The parts he printed do not need to withstand high pressure so you can make them out of plastic. Barrels are very different and need to be made of high strength steel to withstand 50K psi. If you can do this with titanium you can make a fully functional firearm (or you can just buy a conventionally made steel barrel).

[VRW Conspirator]

3D printers can print with titanium now

Does this mean I can make my own set of Ronco knives, now?

[demshateGod]

Last time I saw he was able to get six shots before his lower broke. Is he getting more out of them now? Maybe I should watch the video.

[SandRat]

An Full Automatic continues to fire so long as the trigger is held down functioning like a machine gun until all rounds are spent.

This is not the AR-15. The AR-15 is a Semiautomatic, every time the trigger is pulled it fires 1 round.

[Manta]

Dunno, I just stumbled across this video. I’m not really a gun connoisseur.

[Kevmo]

For the 3D printer ping list

[E. Pluribus Unum]

CNC milling machines are getting pretty cheap, too, and it seems to me that being able to fabricate in metal instead of plastic would be reason enough to channel DIY firearm efforts in that direction.

[ClearCase_guy]

Yup. It's sloppy reporting like this that gets the media and the public saying things like "The kid who shot up the school had an AR-15! That's a machine gun!! He was probably firing 300 bullets a minute!!!! We need to make AR-15s, or anything like them completely illegal! Who goes hunting with a machine gun?!"

If the public understood the reality, there would be a lot less anti-gun fervor.

[Ol' Dan Tucker]

Dunno, I just stumbled across this video. I’m not really a gun connoisseur.

He 3D printed the 'magazine', not the 'machine gun'

He even says so at the end of the video.

Sigh...

[driftdiver]

I think he’s only printing certain parts as an earlier poster stated. While the technology exists to print with metals from what I’ve read it is only capable of firing a small number (I heard 6) shots before failing.

He’s not printing or using the printed uppers, that is a regular firearm. As I understand firearm laws you can make lowers and other parts all day long legally. In the case of an AR15 the upper is the regulated part which requires a firearm manufacturers license to make.

[demshateGod]

The one where he’s shooting full auto is a normal gun with a printed mag. While that’s significant, they haven’t been able to print a decent lower. It’ll happen but they’re not there yet.

[SandRat]

If the public understood the reality, there would be a lot less anti-gun fervor.

The public is to attached to the Liberl MSC for information to grasp reality.

[ryan71]

If it get to a point where we have to BUILD OUR OWN, we’re in big trouble.

[Ol' Dan Tucker]

He’s not printing or using the printed uppers, that is a regular firearm. As I understand firearm laws you can make lowers and other parts all day long legally. In the case of an AR15 the upper is the regulated part which requires a firearm manufacturers license to make.

No, you've got it backwards. It's the lower receiver that is serialized and therefore, regulated.

And they're printing just the magazines. In the video, it's white, but it could certainly be printed in black.

[dennisw]

Wake up!
THE ONLY PRINTING GOING ON IS IN PLASTICS!!!!

Print a plastic water pistol that works...This will impress me and it is doubtful it can be done at this point. Plus how strong and durable are the plastics that are printed compared to the usual injection molding

[Dead Corpse]

I’m in when they can print up an M2.

[Manta]

If Jay Leno can print parts (gears) for his Stanley Steamer?

When I watched both videos, especially the Beck video, I got the definite impression that a fully functioning weapon could be printed. Even if on each particular video only parts were mentioned.

I am NOT in anyway knowledgeable about this stuff however.

[demshateGod]

It’s very cool stuff. Thanks for posting.

[backwoods-engineer]

1) This is not a machine gun. It has been illegal to manufacture machine guns for transfer to 'civilians' (non-LEO/mil) since 1986.

2) That is not even a complete AR-15. It is only the lower receiver, the part that holds the trigger and stands between the barrel/upper receiver/bolt assembly and the shoulder stock. The barrel, upper receiver, trigger group, bolt, bolt carrier, and charging handle all have to be manufactured by conventional means (milling machine).

3) On my blog, I go into the technical aspects of this: "Innovation Beats Gun Control, Every Time."

[demshateGod]

The stripped lower is the regulated part.

[Vince Ferrer]

Facinating interview. Both men have a pretty good grasp of the implications of the technology. But I think they both got close to, but have missed, the wider ramifications of regulation. The true facist/communist state was impossible before the industrial revolution, because the industrial revolution collectivised and commoditized manufacturing to the point where it could be captured and regulated.

Additive manufacturing short circuits this and does an end around both big industry and big government. It puts power back into the ordinary citizen's hands in ways that it hasn't been since the industrial revolution. This is the genie that is out of the bottle.

[WKUHilltopper]

I’ve never seen an AR-15 machine gun.

[Manta]

Instead of Jefferson’s “yeoman farmer” we’ll have “yeoman manufacturer” ?

[Vince Ferrer]

THE ONLY PRINTING GOING ON IS IN PLASTICS!!!!

This is not true. The additive manufacturing world is 20 years old, getting very large, and includes many different technologies.

The very cheap machines that are coming out for home use print plastic, yes. But step up a grade in quality and price, and you can buy machines that can print in metal, ceramics, sand, glass, and even wood. I don't see anything in a gun that someone could not make on a current metal printer, except maybe the spring.

[Vendome]

The lower is regulated. You can buy all the uppers you want without FFL.

[I want the USA back]

Guess there will be a ban on 3d printers.

[Manta]

Vince,

Thank you!

[Dead Corpse]

No. You can print a lower receiver that can be built to be functional.

For the magazine, I’m not sure how they are doing that. Normally, you’d have a metal spring with a polymer follower. If they figured out a way to “print” a poly spring inside the body of the magazine with an integral follower, that’d be quite a trick.

[driftdiver]

Thats the impression he wants you to have but I think its incorrect.

Not sure why Glenn is pushing this story. I think he’s just trying to stir things up.

[backwoods-engineer]

Watch the video. Cody shoots semi auto then full auto. Unless he has a very very fast trigger pull.

Tell me you are not this uneducated about guns. Please.

A slide-fire stock is NOT a machine gun.

[MrB]

And it’d be pretty tough to regulate springs...

[riverrunner]

The early colt ARs use the same reciver as the M16 only it didn’t have the auto sear.

Up until 83 one could buy a auto sear for around 80 dollars then the BATF ruled that the sear itself was a machine gun.

[Last Dakotan]

You can buy all the uppers you want without FFL.

Just not now...

[longtermmemmory]

if anything this makes magazines a pointless exercise in law.

This is about taking civil rights without due process.

[Manta]

Man, I knew you gun guys would be all over me like a cheap suit when i posted that link.

[backwoods-engineer]

I don't see anything in a gun that someone could not make on a current metal printer, except maybe the spring.

Bull!

Show me a printed barrel that can stand 50,000 CUP pressure on a sintered metal printer. You can't. It would fly apart after 1 shot.

[backwoods-engineer]

Man, I knew you gun guys would be all over me like a cheap suit when i posted that link.

Sorry, not trying to be mean. It's just that we see the same misinformation all over the place, and maybe we get a little tired of refuting it.

I'll try to be nicer, since I know you're not trolling :-)

[Dead Corpse]

Cody has a demo video for the magazine. Part II has him first shooting in semiauto, then clicking up the happy switch to full. Looks like he has a nice little can on it too.

In the video I mention above, he's using a printed mag... But I'd go dimes to doughnuts the rest of the rifle is a registered Class III and not one of his printed receivers.

[IYAS9YAS]

He’s not printing or using the printed uppers, that is a regular firearm. As I understand firearm laws you can make lowers and other parts all day long legally. In the case of an AR15 the upper is the regulated part which requires a firearm manufacturers license to make.

Others have pointed out the lower is the firearm, but they didn't mention that you can, legally, make your own lower, for your own use, with no intent to sell (as long as ownership of said item is legal where you live). You can buy 80% lowers on-line, finish them yourself, and maintain the lower as your own, and it needs no serial number (but is recommended strictly for security purposes), doesn't have to go through an FFL, nor does it require a manufacturer's permit.

[DMZFrank]

In addition to the auto sear, the design of the selector lever, hammer,disconnector and bolt carrier differ from the one in the commercial AR-15.

[carriage_hill]

I’d bet they’re working on ‘regulations’, already.

http://gcn.com/blogs/emerging-tech/2012/10/will-3d-printing-be-regulated.aspx

[TYVets]

This is not the AR-15. The AR-15 is a Semiautomatic, every time the trigger is pulled it fires 1 round.

I saw a new terminology for A-15s.

They are now called Modern Sportsmans Rifles.

[houeto]

Last time I saw he was able to get six shots before his lower broke. Is he getting more out of them now?

Oh yea, that was many weeks ago. They are getting better at this by the minute.
