Vlad_the_Inaner: vadum: I have never worked for the TSA, but unless they are using plastic bullets, I think they can still detect them.

I have invented this very hard but non-metallic material.

I think I'll call it....'glass'

[ecx.images-amazon.com image 160x160]


I wonder how difficult it would be to make a glass bullet that didn't shatter upon firing.

namatad: BarkingUnicorn: Antivirus companies can play their game in this market and make some money.  Add software to 3D printers that checks each file against a signature database and rejects files that print guns.  Charge subscription fees for updates.  Same business model they follow now.  Make it mandatory for all 3D printers and buyers.

Of course signature-based protection isn't complete.  For an additional fee, we can give you behavioral and heuristic real-time protection against uncatalogued "threats."  Anything that might be a gun part will be rejected.

who the fark would buy a printer which was only able to print certain approved patterns??
LOLOLOLOLOLL
FARK THAT shiat

esp since most people buying these printers will be printing custom made patterns. home made or what not.
the whole idea is silly


Who would buy a computer that doesn't play Flash content?  People buy things for what things do, not for what they won't do.

Antivirus software sells pretty well without being perfect.  If it was mandatory, it would sell even better.  I wasn't talking about eliminating 3D printed guns; I was talking about making money off the perceived problem.

EngineerBob: thenumber5: Rincewind53: Honest Bender: Why do they "have" to outlaw them?  Correct me if I'm wrong, but isn't it perfectly legal for me to manufacture my own firearms now?  What difference does it make how I do so?  Or are things just legal until it becomes too easy to do?

Key word here is  plastic. aka, invisible to metal detectors, therefore more dangerous and not permissible under federal law (I think).

good thing there "Plastic Gun" has the metal barrel

..until some bright boy makes  ceramic barrels.


feasible, but I'd want to see some sort of extended testing on the barrel before I'd consider risking my life with one.
start with ceramic coated insides of a metal barrel (obviously final ID is the same as a conventional weapon of the same caliber)

Dimensio: Great Janitor: I haven't read this thread, so if this has been said, I'm sorry, but it might be worth repeating:

You can not build a working gun out of plastic and expect it to work.  Can Not Be Done.  Only someone with a limited to zero knowledge of how guns work would think that plastic guns are a threat.

When you load a gun and pull the trigger, you are pretty much creating an explosion within the gun controlled in such a way that the bullet portion of the round flies out of the barrel of the gun and the gas used to expel the projectile is recycled to eject the spent cartridge allowing a new round to be loaded into the chamber.  That is why guns are made out of metal, strong metal, so that when the explosion is created within the gun, the gun doesn't blow up in your hands.  Plastic just doesn't have the strength.  It's fear mongering, nothing more, to suggest that you can build a gun out of plastic.  And only an idiot with zero knowledge of how guns function would even suggest such a thing.

Are you attempting to imply that the distinguished Senator Schumer is less than knowledgeable regarding firearms technology?

I suspect that you may next attempt to convince readers that Representative Carolyn McCarthy has attempted to ban firearm features without knowing what they actually are.

Tellingthem: And just wait until hand held lasers become more powerful. We will then have untraceable phasers. No need to worry about bullets or noise suppression. Just a click and you can kill someone.


Keep waiting. There is a upper limit to the amount of rapidly releasable energy that you can squeeze into a object of a certain size. A laser powerful enough to do as much damages as a bullet at an equivalent range will require a large amount of joules, and barring antimatter or some other type of exotic energy storage, there is not reason to expect a handheld laser weapon anytime soon.

poorjon: Honest Bender: Why do they "have" to outlaw them?  Correct me if I'm wrong, but isn't it perfectly legal for me to manufacture my own firearms now?  What difference does it make how I do so?  Or are things just legal until it becomes too easy to do?

I think it's because they're printing the only part of the gun that actually has to be registered. You can buy all the barrels and triggers and hammers you want, but it's this hunk of stuff that makes it all work.


You don't have to register a frame or receiver that you make yourself.

I know someone who has a Colt Commander-style gun that is absolutely sterile (ie., no serial number, no manufacturer marks) because he took a rough frame casting and finished it himself.  It's perfectly legal and it doesn't have to be marked because he made it for himself.  If he were to sell it, he'd have to mark it, and he's joked that if he ever does the serial number will be FUATF001.

Also, for the purposes of being legal, you could make an almost completely plastic pistol as a muzzleloader, designed to use black powder or a black powder substitute (like Pyrodex pellets, which can be glued to the base of a bullet).  You wouldn't have to include any metal to make it visible because muzzleloaders are exempt from the laws.

Here is the law itself:

      (p)(1) It shall be unlawful for any person to manufacture,
    import, sell, ship, deliver, possess, transfer, or receive any
    firearm -
        (A) that, after removal of grips, stocks, and magazines, is not
      as detectable as the Security Exemplar, by walk-through metal
      detectors calibrated and operated to detect the Security
      Exemplar; or
        (B) any major component of which, when subjected to inspection
      by the types of x-ray machines commonly used at airports, does
      not generate an image that accurately depicts the shape of the
      component. Barium sulfate or other compounds may be used in the
      fabrication of the component.


Here is the legal definition of a firearm:

(3) The term "firearm" means (A) any weapon (including a starter
    gun) which will or is designed to or may readily be converted to
    expel a projectile by the action of an explosive; (B) the frame or
    receiver of any such weapon; (C) any firearm muffler or firearm
    silencer; or (D) any destructive device. Such term does not include
    an antique firearm.


Here is how "antique firearm" is defined:

(16) The term "antique firearm" means -
        (A) any firearm (including any firearm with a matchlock,
      flintlock, percussion cap, or similar type of ignition system)
      manufactured in or before 1898; or
        (B) any replica of any firearm described in subparagraph (A) if
      such replica -
          (i) is not designed or redesigned for using rimfire or
        conventional centerfire fixed ammunition, or
          (ii) uses rimfire or conventional centerfire fixed ammunition
        which is no longer manufactured in the United States and which
        is not readily available in the ordinary channels of commercial
        trade; or
        (C) any muzzle loading rifle, muzzle loading shotgun, or muzzle
      loading pistol, which is designed to use black powder, or a black
      powder substitute, and which cannot use fixed ammunition.
For
      purposes of this subparagraph, the term "antique firearm" shall
      not include any weapon which incorporates a firearm frame or
      receiver, any firearm which is converted into a muzzle loading
      weapon, or any muzzle loading weapon which can be readily
      converted to fire fixed ammunition by replacing the barrel, bolt,
      breechblock, or any combination thereof.


The way I read it, if you make it a muzzleloader, it's completely kosher to make it so that it won't be detected by a metal detector.

No, no they are not.  Plastic guns that function just like real guns are movie myths.  If you honestly believe that guns made of plastic are just as functional as ones manufactured by Glock out of steel, then you might as well tell the American public to hide in their refrigerators in the event of nuclear attack or in the event of alien invasion, writing a computer virus on an Apple laptop will save us all.

"I have examined Man's wonderful inventions. And I tell you that in the arts of life man invents nothing; but in the arts of death he outdoes Nature herself, and produces by chemistry and machinery all the slaughter of plague, pestilence, and famine. The peasant I tempt today eats and drinks what was eaten and drunk by the peasants of ten thousand years ago; and the house he lives in has not altered as much in a thousand centuries as the fashion of a lady's bonnet in a score of weeks. But when he goes out to slay, he carries a marvel of mechanism that lets loose at the touch of his finger all the hidden molecular energies, and leaves the javelin, the arrow, the blowpipe of his fathers far behind. In the arts of peace Man is a bungler. I have seen his cotton factories and the like, with machinery that a greedy dog could have invented if it had wanted money instead of food. I know his clumsy typewriters and bungling locomotives and tedious bicycles: they are toys compared to the Maxim gun, the submarine torpedo boat. There is nothing in Man's industrial machinery but his greed and sloth: his heart is in his weapons."

The 3D printed guns that Defense Distributed have a piece of metal inside (aside from a nail that is used as a firing pin) to make it detectable by metal detectors. However, no one who prints one of their guns will have to put the metal piece in it. Considering that these printed guns also get destroyed after a few shots fired, they're almost perfect assassination weapons.

There has to be way better control of these things.


No, there doesn't have to be a way. You might want there to be a way, but that doesn't mean there must.

BASIC ZIP GUN:

1. piece of 1/4" schedule 80 pipe about 12" long;

2. 1/4" pipe cap;

3. Drill 1/16" hole in center of cap;

4. clip 6d nail about 3/8" long for a firing pin;

5. Wrap the first 4" of the barrel in at least 10 layers of duct tape, so it won't blow your hand off if the gun explodes;

6. fabricate handle of wood and clapper from a piece of scrap metal and some strips of old inner tube.

If a silencer/sound reducer is desired, screw a 1/4" by 1" reducer into the barrel and add a piece of 1" pipe 3" or so long.  Cover the end of the silencer with a piece of old inner tube, and tape it airtight shut.

DO NOT assemble the weapon until you really need it, and also take it apart and throw the parts away one by one as soon as the weapon is used.

If a larger bore is required, use 3/8" pipe and .38 special ammo.  1/2" pipe and .45 cal ammo may also be used, but this is very dangerous and too much power for the gun in question.   For a shotgun, use 12 ga. shells and 3/4" inch pipe.

For more good recipes, download "U.S. Army Training Manual # 210: Improvised Weapons" available on your friendly local Innertubes.

Second Amendment types don't like me because I do not even own a gun, and I am fond of saying: "When the revolution comes, I can get all the weapons I need: just kill one police officer."

Oh I know but things will get there someday. I think it would be pretty damn cool to have a phaser and would love to play with one. All it takes is time and the technology will advance. That is what I see with this kind of stuff. Not that right now a 3d gun is mostly a toy and nothing to be scared of. But in ten or 20 years who knows? I work in the art biz and I can already see how 3d printers can change the sculpture market. Why spend 20k on a limited edition bronze when you could print the same thing off at home with a proper scan. Plus you can scale it to whatever size you want. To me this is the next big advancement in my lifetime. Being able to print off objects at home. From art to weapons. It's fascinating.
 
2013-05-05 07:23:52 PM
People are forgetting that the point of making a 3d printed gun was not to mass produce them, it was to show that gun restriction, like the drug war, is a hopeless fight.

First, bullet proof materials still take damage when hit with bullets.  I can put a bullet proof vest on, get shot and still face the chance of a broken rib or two and some internal damage from the impact of the bullet hitting the vest.

Second, bullet proof plastics can't resist the explosions that occur when you fire a gun, and that's assuming you can make an all plastic gun that can hit a bullet with enough force to fire a bullet.

Again, there is a reason why Glock makes their guns out of steel and not plastic.

Bulletproof glass is typically layers of glass and plastics, not just plastic

helmets can crack from impact, between the exterior hard plastic and the interior foam your head usually won't

The real issue here is one of state of the art vs. state of the shelf. While there are plastics able to withstand the forces of a bullet exploding and there are 3D printing technologies capable of using some of these plastics, they are not readily available to the average consumer. Consumer level 3D printer use lower strength thermo plastics and lack the resolution to make usable weapons and it will be quite a while until they do. Look at the capabilities of industrial publishers compared to what you can do with a consumer level printer. Now think of how long we've had desk top printers. There's a long slow road of progress before we will have consumer level 3D printers capable of printing weapons that pose a real threat to public safety.

I don't think anyone in this thread is saying they're JUST as functional. They're single shot, for crying out loud - but functional for 2, 3, maybe even 4 shots? They're already done that. They're planning on releasing the video for the test firing on Monday.

Couple of interesting points:

"Despite the explosion that just occurred inside of it, both the barrel and the body of the gun seem entirely unscathed. The verdict: it worked. The Liberator fired a standard .380 handgun round without visible damage"

"Wilson switched out the Liberator's barrel for a higher-charge 5.7×28 rifle cartridge. He and John retreated to a safe distance, and John pulled his yellow string again. This time the gun exploded,"


So no, I don't think you or I would currently want to test fire one outselves.. But this IS only version 1.0 :)

You can buy a very good plastic flare gun at any outboard motor store, it fires .410 shotgun shells and white phosphorus meteor charges much more damaging than any regular shotgun shell.

dittybopper: The way I read it, if you make it a muzzleloader, it's completely kosher to make it so that it won't be detected by a metal detector.


Thinking further, you could make several barrels that you could "preload" and just pop into the frame.  It would take you all of 3 seconds to do that, if you designed it right.  Another possible method is to make a "pepperbox" sort of arrangement so you have multiple shots without having to reload, or even something like the "harmonica gun".

Sure, they are crude by today's standards, but crude can also be effective.  If you can sneak something like that into a place where no one else has a gun, because you have to go through a metal detector, you've got a major advantage.

Since you can crank them out by the dozens, the "harmonica" or the barrel assembly of the pepperbox could be largely disposable.  You take a few loaded and capped barrel assemblies and you drop the used one, pop in the fresh one.  Since they'd be loaded at the muzzle and wouldn't use fixed ammo, they wouldn't be firearms under the legal definition, so you couldn't be charged with violating the ban on non-detectable firearms, because it's not legally a firearm.

The one fly in the ointment is the bullets.  They have to be made of metal, because plastic just isn't going to be effective enough.  Still, it would be easier to sneak them in as something that doesn't look like bullets (perhaps have them as beads on a necklace or something).

I am socially acquainted with many police officers through the Patriot Movement, and their response always is: "Don't you understand, when the right time comes, most of the Police will switch sides?"

No, I do not know that.  I can hope, but in a total social breakdown, I believe the Police will turn feral and prey off the citizens, to whatever extent they are not doing so already. The definition of a police state is one where criminals run the government; any time I can't tell the difference between the cops and the crooks, I have to say we are mighty damn close.

Aplastic bullet orplastic baton round (PBR) is a projectile fired from a specialised gun. Although designed as a non-lethal weapon they have still caused several deaths. They are generally used for (notably in). Plastic bullets were developed by theto replace their in an attempt to reduce fatalities. If misused they can still cause fatal injury.

Which of these certain kinds of plastics are compatible with 3D laser manufacturing? Lexan? Not even. High-mod poly. Uh uh. Anything not clear that is light and bullet resistant is imbedded with spectra, kevlar or Dyn. Again... ain't happening.

Yes, we can make very tough plastics. We don't make them with 3D printer compatible resins. If you were serious about having a 'real' plastic gun, it would be much more effective to use the appropriate plastics in a subtractive machining process.

olddinosaur: Great Janitor: radarlove: I think it's great that y'all know so much about guns, but it looks like none of you really know much about plastics.

Some of them can take a lot of punishment, which is why we make bulletproof windows and helmets out of certain kinds.

First, bullet proof materials still take damage when hit with bullets.  I can put a bullet proof vest on, get shot and still face the chance of a broken rib or two and some internal damage from the impact of the bullet hitting the vest.

Second, bullet proof plastics can't resist the explosions that occur when you fire a gun, and that's assuming you can make an all plastic gun that can hit a bullet with enough force to fire a bullet.

Again, there is a reason why Glock makes their guns out of steel and not plastic.

You can buy a very good plastic flare gun at any outboard motor store, it fires .410 shotgun shells and white phosphorus meteor charges much more damaging than any regular shotgun shell.


The rounds fired in a flare gun have much less power than a real shotgun shell. Go buy a flare gun and put some squirrel shells in it. I dare you.
Not really. Don't do it.

olddinosaur: utah dude: olddinosaur: Second Amendment types don't like me because I do not even own a gun, and I am fond of saying: "When the revolution comes, I can get all the weapons I need: just kill one police officer."

even if that police officer was your friend ? or brother ?

I am socially acquainted with many police officers through the Patriot Movement, and their response always is: "Don't you understand, when the right time comes, most of the Police will switch sides?"

No, I do not know that.  I can hope, but in a total social breakdown, I believe the Police will turn feral and prey off the citizens, to whatever extent they are not doing so already. The definition of a police state is one where criminals run the government; any time I can't tell the difference between the cops and the crooks, I have to say we are mighty damn close.


dino i haven't see u post in at least 3 years. what happened?

bigbadideasinaction: ke meth,


if meth was legal i'd buy "Pfizer brand XR StereoSelect Methamphetamine with Vitamin B6" (tm)  and i'd not have to worry about home cookers.

rattchett: I am pro-gun, but I still think Wayne LaPierre is a douche bag.  You anti-gun folks feel the same way about Schumer and Feinstein, right?


I am a Libertarian and defend your right to bear arms, but yes some reasonable restrictions are in order, thanks to the innumerable shirtheads out there who make it hard on us defense types.  LaPierre is a paid shill, and so are Feinstein and the others.

Feinstein by the way carries a a gun in her purse, has done so ever since the Moscone/Milk murders catapulted her to national fame; prior to that she was an obscure S.F. City Council member.

She refuses to place her own body in physical danger, but refuses to sallow you the same right to defend yourself.

Thunderboy: Something tells me it would be a lot cheaper and easier to just buy a shiat .22 on the street than it would be to buy a Makerbot, supplies, ammunition (or are they printing that too?), download the schematic, print a test run, then print the actual gun.


What makes you think you're limited to a semiautomatic 3D printed gun?

mike_the_engineer: Rincewind53: Key word here is  plastic. aka, invisible to metal detectors, therefore more dangerous

Yeah, but there's a flaw in your logic.  Bullets are made of metal.  So you'd have to walk through the metal detector with an empty gun.


Do you really think it would be difficult to get something as small as a AAA battery through (or around) a metal detector? Heck, you could probably even put it inside a AAA battery and throw it in your camera.

redmid17: Vlad_the_Inaner: vadum: I have never worked for the TSA, but unless they are using plastic bullets, I think they can still detect them.

I have invented this very hard but non-metallic material.

I think I'll call it....'glass'

Sweet let me know when you figure out a way to propel it at high velocity without gun powder.


you're right.  I'll start working on non-metallic gun power right away!

/done!

Right, I mean it's not like they x-ray your luggage at the airport or anything.

You don't know much about airport security do you? I'm guessing you also don't know what would happen to glass if it were subjected to the kind of pressure that would gun powder would produce.

untaken_name: RexTalionis: Considering that these printed guns also get destroyed after a few shots fired, they're almost perfect assassination weapons.

They don't vanish, dude. They just stop shooting properly. You'd probably want something more reliable for a real assassination.


A plastic gun used for an assassination only needs to be fired once or twice.  Since it's made of plastic it can easily be burned or melted beyond recognition.
