3-D Printed Gun Only Lasts 6 Shots
thunderfeeds.com ^ | 3 December, 2012 | Robert Beckhusen

Posted on 12/03/2012 3:31:26 PM PST by marktwain

Over the weekend, a group of 3-D printing gunsmiths took a partially printed rifle out to test how long its plastic parts survived spewing bullets. The result? Six rounds until it snapped apart....

I’d hope that homemade guns will be around a plenty, or even more so, if/when there are no more non-homemade guns.

“partially printed rifle”????

Shouldn’t they have tested a completely printed one?

Limitation probably easily overcome by adding metal into the printing process at various stages.

Not bad. In an insurgency all that would be needed is one shot. That would allow one to (hopefully) kill someone who has a superior weapon. Similar to the single-shot WW2 FP-45 Liberator pistol that was distributed to resistance fighters. A cheap(er) 3D printer can enable ‘printing’ of weapons that, although not the best, would enable quite a lot of freedom fighting (or mischief, depending on which side you are on) to be accomplished.

It’s a start.

When guns were first invented, they were only single shot.

It’s not the gun’s fault that they didn’t use the proper paper bullets!

Replace the printer with a CNC mill, and rewrite the code.

No problem.

One of the Russian's more effective recent weapons for stopping enemy movements was the small landmines that had just enough power to maim a foot. Obviously they got in a lot of trouble with them because they were attractive to young children ~ but they worked. They were also cheap. You could probably print them up for pennies ~ then load them.

I was just thinking that if you had a bread truck toting around the 3D printing rig you could spew out 5 round printed firearms just all over the place ~ for the locals to pick up.

You wouldn't need to go to the elaborate lengths you do with heavier full iron weaponry, or with dope dealing ~ just print up the guns, load them on the fly, and toss them along side roads, in alleys, in yards ~ a few people could probably arm a good sized town before being suspected ~ even with a plethora of unmanned drones in the region.

There's also gotta' be a design that's invisible to rader ~ get the specs out on that one now for future freedom fighters to know about.

And, they were made out of wood ~ hollowed out tree trunks in fact ~ they tossed rocks ~ everybody wanted one!

Did you know that entire societies learned to stop urinating in ditches and turned to formal outhouse arrangements just so the saltpeter (potassium nitrate) could be harvested from urine?

Firearms changed societal behavior in truly massive ways ~ and improved public health!

Slightly misleading title, but that’s Wired for you... Only the lower receiver was printed, all the rest was kit gun with metal parts. Usefulness of this particular design is questionable at best, but it’s a great conversation starter.

OH! DEAR GREAT GOD!
Everyone with a computer can make a gun -
Everyone will be carrying guns -
Guns that can’t be registered -
Guns that we can’t track -
Guns with no serial numbers -
Guns we can’t tax -

Poor Chucky Schumer - must be going nuts at night staying awake thinking about this - thinking about what can, what might happen - worrying that someone might not like him, and shoot him with a 3-D printed paper bullet, from a 3-D printed gun. OOOOHHH THE HORROR!!!

Oh well, back to my crossword puzzle.

I’ve owned Kel-tecs for years, and have never experienced nor heard of the kind of failure you imply.

Don’t forget that unless you have a reasonable basis for making that statement about a solid American gun company, you may be held liable for defamation.

That *is* interesting! I knew urine was used in the formulation of early gunpowder (I remember reading a treatise arguing whether or not a wine drinker’s urine was superior that of an ale man’s whizz). I didn’t know that there was such a wide ranging effect on societies, though.

News following art following news? I just saw last week’s episode of CSI Las Vegas where they had this as the weapon of choice by the bad guy. That’s what whacko liberal Ted Danson (actually does a good job on this show) said to one of my fav’s - Elizabeth Shue - one shot is all you need.

For those interested, the following guns were made IN PRISON, including the ammo. This is from an old GUNS AND AMMO magazine from around 1970.

Rather than 3D printer technology, people ought to be thinking of already mature CNC metal machining technology.

Coming soon to Kalifonia:

Anyone found guilty of possession, use or sale of 3d printers shall be guilty of a CLASS A FELONY. (life in prison)

According to US law, the lower receiver is the gun. It is the only part regulated.

Just get some sheet metal, hydraulic press, and drill press and you can make your own AK receivers. Cheaper and easier than plastic.

You can't. That's not how these printers work.

The way they work is to take plastic filament, melt it slightly, then extrude it out a hot tip and build up an object one very small layer at a time. Most of them extrude at 0.15mm out the hot tip. Takes forever to print anything. A whistle takes about 20-30 minutes.

Since the plastic isn't completely melted, it sort of just sticks to the layer underneath it and blends in a partially melted state.

This isn't injection molding. Its like taking a two-mile long strand of angel hair pasta and layering it on top of itself to produce the object.

Works great for rapid prototyping. The object has cohesion and does hold together. Just don't subject it to really serious load.

If you manufacture the parts for a weapon on your own with no intention to sell or transfer the parts or the completed weapon, are you subject to ATF regulations? I’ve heard conflicting opinions and would like to know the answer.

Isn't the point that to run a CNC mill, you need extensive training, but to use a 3d printer, you just have to have the proper file and be able to press the "print" button?

No not really. A CNC mill is controlled in a very similar fashion to that of a 3d printer. The point isn’t about making it an easier process it’s about materials. In other words you don’t need steel or aluminum which most people can’t make at home.

Short answer: No, unless you are producing a prohibited weapon. The 9th circuit even ruled that you could legally produce machine guns for yourself, but the Supreme Court, specifically Justice Scalia, told them to retract the finding under another ruling, Gonzales v. Raich, that held that growing marijuana in your own house for your own use, was interstate commerce!
