Time to buy a 3D Printer...maybe the best $10k I've ever spent...the new Cuomo Mag

I'm highly sceptical, it would probably start with Glock frame, degrade to making an AR lower then as everyone would get even more drunk there would be competition on who can print the biggest dick on a dick and by morning that printer would be toast and swimming in the puddle of puke and shit.

That right there is funny. I don't care who you are.

Yep. I got these files a while ago. Then I started googling for a 3D printing service. Upload the file, place you order, get a "printed" part delivered to your door. So far, i have not been able to find a service that can print a lower for a price that makes sense. Sure would like to try one "printed" with titanium or stainless steel.

How about the trigger group? Pins should be easy to get, and I could try to make the detents (I have a 7x14 lathe). If you could get the BCG printed out, within spec, that would be sweet. We could just make the parts we cannot buy right now. [rockon] Actually, you might be able to get a machine shop, with CNC tools to make the inner parts of the rifles. I just wish they had more for the AR10 in the file set.

EXCEPT - some "printing" can be done with metals. Check out the materials this company can use: "http:// i . materialise . com/materials" I am purposely avoiding giving them a link, but it appears they can use titanium, stainless steel, brass, bronze and others. There are size restrictions, based on the size of their printers, and the issue of "cost" but it can be done with metal. This technology is in its infancy. If someone can "print" working gun parts now, it is not inconceivable someone could print an entire gun in the future.

Thing is, unless you add rifling to that printed metal barrel your barrel is worthless beyond like 10 yards. And I don't have any idea how the printer would be able to add good rifling to the barrel.

There are a couple of sub $2k 3d printers that have a deck large enough to print an AR lower.

If you're only after magazines you can spend as little as $1000 for an UP! Mini 3d printer. More than adequate to print a magazine.


I have been doing a little homework recently on 3d printers (Because I want one). Printed ABS is about 30% as strong as normal injection molded ABS. PLA is a bit stronger, but more brittle if I recall correctly.

There are also a new generation of sintered metal laser 3d printers. They are cooler than they sound, and print with actual metal. But they are still WAY out of the realm of the average home user, in so far as cost.

How hard is it to actually design a part and get it programmed so the printer can make it?

I've looked a lot at CNC plasma tables and similar devices - and it seems like the actual parts design and programming is the hard part. Spending money is easy.

it's retarded. If you need a hi cap mag, go across the border and buy it.

.gov keeps writing laws and people keep inventing stupid shit to go around it. This madness has to stop.

Wait, what?


glock...M&P...etc etc etc etc?

If I remember correctly - that law originally came out around the time that Glocks started appearing on the market - because everybody got into a tizzy about "plastic guns" that could go thru metal detectors and get snuck on planes and so forth. Just like the "assault weapon" banning idiots of today - the idiots of yesteryear didn't have a clue as to what they were talking about because some parts of the gun still have to be metal.

So this Israel guy is apparently itching to join the Pantheon of legislative stupidity - because he absolutely no idea that all a 3D printer could be used for - is to make the SAME EXACT PARTS - that are already being made out of plastic right now with molds. And the resulting printed parts probably wouldn't be anywhere near as robust as the molded parts we have now - so the gun might literally come apart in the person's hand.

The real problem is that legislators seem to almost universally be out to prove how goddamed stupid they are and how they have an perverse desire to constantly meddle in things they know absolutely nothing about.
 
this may be a difficult concept to grasp, but it's much cheaper and faster to CNC out dies to make that mag and many many more. It's not quite the Start Treck replicator shit, but easier methods exist if you need that mag.

I was talking to a friend about this and SURPRISE he has a 3D printer at work... One that he has full access to... And I have permission to use it for cost of material... O.O found a design that was tested and seemed to hold up real nice. Opened it up in SketchUp and started playing... pretty cool. Going to toy with it, customize a serial number, selector labels, maybe an engraving (Not really engraved, just printed in... Or embossed).. Dunno. Hopefully in a few weeks I'll be able to set aside some time to swing in there and have some fun.
 
Question, there are sites that will let you upload a design file, and they'll print it for you and mail it. . . Now, If they print a lower and mail it to you... It's obviously illegal... BUT I found a design where the lower is in two pieces. In order for the threads in the buffer to properly print he had to make it a separate part. So the buffer threads, and that curse that sits on the web of your thumb, aren't connected to the lower at all and have to be assembled later. >.> So would that make it legal to print and ship the parts separately, seeing as it's not REALLY a lower?

It's easy. But it depends on the quality of the machine. The metal printing machines that use frikkin lasers should be mind numbingly easy as they have the precision of a laser. If you had a traditional plastic printer, it would still work, but the highest resolution printers in the "home owner" cost level will do .25mm. Slightly more expensive ones.. Maybe 5-10k will do .025mm. Maybe better.. I am not honestly sure since I can't hope to afford one. ;)

The problem with even a printed steel medium is it still won't be as strong as properly forged barrel. It'll work in a pinch.. probably.

Can either piece be used to make a functional weapon? Think about an 80% lower. It's CLEARLY a lower. But it doesn't have the requisite amount of features to constitute a "lower". If you had plastic parts, neither of them has the requisite amount of features. In this case it's the joining of the pair that would make them a legal firearm (assuming it's an AR).

Keep in mind.. I am not a lawyer and I don't own a 3d printer.. but that's my argument.

Additionally.. if you were asking me. (IF). I would make them a top half and a lower half. That way you have the bulk of the firing stress being delivered to the stock, the top half would be a contiguous part. Then you have a large bearing surface to join the top/bottom to transfer the stress to the grip portion.

Did you know that printers are being invented that can manufacture DRUGS ?

At some point the software files will be controlled, even illegal.

Today some pictures can land you in prison. Child porn, for example.

So files that can make a Magazine or Drugs becoming illegal are no stretch at all.

Difference between this and an 80% is it is literally ONE bolt to make it a receiver. *Shrug* Doesn't effect me, I'll be printing by April.

This is the design I'll most likely be printing...

With the tumbhole stock he's printing, it looks like it could take a beating.

It's the internet... Make it as illegal as you want..... Good luck enforcing it. Espc. when it's a free product. You'd be DISGUSTED if you could see how freely child porn is traded across the interweb. Not even counting what gets traded on the Deep Web >.>

AND Once you've printed, they'll have no way of knowing whether or not you printed it from an illegal design, when it was printed, who printed it, or anything else. You could print magazines stamped January 1776 ... You could print EXACT replicas of ANY major manufacturers mags and the cops would be hard pressed to prove it's a phoney.
 
Screw the mags...

They are going to have a complete effing melt down once they start realizing the possibilities hearing about printable, disposable suppressors...
