Once a design escapes to the Internet, it cannot be recaptured.

Guns should be made of metal (possibly partly ceramics). That’s why God invented gun oil.

Perhaps somebody can answer a question for me, as I’m not really a gun expert.

It seems to me that existing 3d printed models, would tend to be very dangerous to fire.

Everybody agrees they only last so many rounds, and I assume one would really not want to be holding it when it fails.

Or am I missing something?

That’s an amazing story. In all honesty, I’m not that big on guns and ammo, but this 3-D printer might just get me interested in guns as a hobby.

We've got to get past the idea that we need to make the entire gun out of extruded plastic. You simply can't make an acceptable barrel out of plastic.

Personally, I'm looking for someone to take a pair of these:

And make one of these:

There is an engineering solution to that. Quantify the average lifetime. Get rid of the weapon when it is well within it's predicted lifetime and print another.

I don't intend to give up my heavy metal 1911 style carry piece, but these things are V1.0. I expect V12.8 will be much, much better. These are early days.

Looks like they let it cool between shots.
I figured it would blow up.

Experimentation says you can. For a few shots, anyway.

This isn't a precision hunting rifle or bird gun you take duck hunting. It's a tool of freedom that may only need to be fired once. Butter knife to get a steak knife kind of thing.

When you’re defending your life, you only need it to fire once, for the most part. All the other cockroaches tend to scatter after that.

I can envision a powered metal 3d printer where the parts are designed to be sintered in the oven after "manufacture".

Pick your alloy.

Of course, there’s a certain thrill of pioneering a new gun design, too, Joe admits. “I may be the first person in the history of mankind to fire a bullet through a plastic rifled barrel. It’s an interesting feeling,” he says. “I feel like Samuel Colt.”

A bullet? Maybe.

But not a spud!

Details for the 1.5" SCH 40 Rifled PVC Pipe

After much development and testing, rifled PVC is now a reality.

Range testing indicates about a 50% increase in accuracy for potatoes, and pipe stands up to continuous 300 psi pretty well. This new barrel modification will send potatoes straighter and perhaps most important of all...safer. I say this as I have had experience with a stray potato every now and then, going where you might have not wanted it to go...(through my shop window).

I would probably be reluctant to fire one just for the heck of it. If somebody was knocking at the door and I knew it was all over I would fire away. Tyrants are scared of technology like this. When they have no idea which door they knock on somebody has one of these it gives them pause. 30 or 40 million of these would make a big difference .

They sinter them with a laser as they deposit them. That's pretty expensive right now, but I remember paying $400 for 4K of memory that took up a large S-100 bus card. I expect this to follow Moore's law.

"It seems to me that existing 3d printed models, would tend to be very dangerous to fire...Everybody agrees they only last so many rounds, and I assume one would really not want to be holding it when it fails...Or am I missing something?"

All things are relative. Improvised firearms("zip guns") have long been made by prisoners, partisans, and others who have otherwise been prohibited access to conventionally manufactured weapons about as long as there have been firearms. They've been made from soft metals, wood, plastic etc. I suppose the users have conducted a rudimentary cost-benefit analysis and found that the risk of their firearms failure was an acceptable alternative to going entirely unarmed.

And certainly, while I would not want to be holding one when it blew, both the prior design from a week or two ago and this one fire the .380 which is a (relatively) low pressure cartridge which actually has a lower recommended chamber pressure than a .22 LR, which would minimize the collateral damage in the event of a catastrophic material failure.

The first cars were silly when they were first invented. You could out walk or outrun them, but with innovation, they got better. It’s no different with these guns. They may have very limited usefulness where they currently stand, but with innovation, they’ll get better.

It’s only silly because I can make one that’s better from old plumbing leftovers, and it will never blow up.

Free zip guns have been around for as long as there have been guns.

It’s neat as far as 3D printing goes, and I’d love to play with that sort of stuff.

But the gun is just a novelty, and will remain so for quite a while, imo.

The thing is, that takes more time and effort than just hitting ‘print’ and walking away. Not to mention that you can make dozens of copies fast.

It’s at least as useful as the old FP-45. More importantly it is very disposable and has no tool marks with which to trace it, something you can’t say about the old plumbing rigs.

The non-silly part is the fits that it's giving the PTB. They hate it. Sure, it's a piece of crap. What isn't V1.0? It's in alpha test, it's not ready for beta test. It's one step up from vapor-ware.

But it's caused some brown drawers in DC.

Not bad for a piece of technical piece of crap.

This is about power politics. Not mechanical precision.

Mao taught the liberals that power came from the barrel of a gun. Literally.

And now anyone can download the plans and have power.

The politicians are idiots, because you can download the plans for a grease-gun that fires full auto on an open bolt, built with different equipment, but they don't think that deeply.

This is 100% political. And it's dead accurate in that respect.

if you read up on the concept of liberator guns, you’ll know why.

also being able to make your wn guns freaks out anti-2a gun confiscators. which is funny because anyone can make a gun without a 3-d printer now.

Yes. When I closed up the shop before the storms moved through tonight, my unregistered lathe and milling machine were still right there where I put them some years ago. Bolted to the concrete slab. The tiller still blocking my access to them.

I spent more on that equipment than what it would cost to buy a desktop 3-d printer. Not to mention all the time and busted knuckles learning to use it and developing those skills.

I think a printed semi-automatic will be a game changer. Even if you can shoot through just one mag and dispose it.

The first printed barrel can already take 9 shots so I say we'll see one within a year if the fascists don't cripple 3D printing.

They can't. You can build your own printer if you are so inclined. This 3-d printing stuff has a large opensource communitity behind it.

Think linux, writ small, like the early days when I was downloading a few disks to build a system.

Linux was international before powers tried to kill it.

I believe FR is running on linux.

This is international. It's global. 3-d printing is here to stay, regardless of the politicos.

The only thing to determine is the cost in blood and treasure.

We’re also going to need field expedient ammo - black powder in a cartridge, maybe for use in a multi-barrel setup. Chris Rock anticipated the anti’s next move - bullet control. http://www.youtube.com/watch?v=VZrFVtmRXrw

I have a 3D printed 4 barrel, legal, non-detectable projectile, gun design in my head. Less bulky than the current single shot, more accurate, quick reloads...

Trying to decide if I want to make a proof of principle single shot....

I think these 3D plastic models would make a great one time use gun, for emergency purposes. Holds 9 rounds or so, non reloadable, disposable, and cheap to make. Would come in handy if you’re in a real bind. As far as barrel issues go, maybe using a section of barrel sleeve (for repairing old barrels) would work as an insert. Brownell’s has a range of stock for common calibers.

Fires 9 shots?

A magazine with 9 cartridges is enough to get you arrested on a felony charge in New York State.

That’s assuming you have somehow managed to get a state permit to own a pistol in the first place.

Sure, until the Democrats win on the gun issue. I’d rather have the 3D-printed gun perfected before then, rather than try and figure it out afterwards.

Re: Post #10 - Your plumbing pipe shotgun idea

When I was a kid we were obsessed with the military and had BB gun wars between the Marines and the Chi-coms all the time.

We also made several smooth bore guns using plumbers pipe and used them to fire marbles and steelies.
We mounted the barrels on small two wheeled carriages made of wood scraps and baby coach wheels and towed them around pretending they were howitzers.

We made some of our own gunpowder and also got gunpowder by emptying .22 cartridges and shotgun shells. In those days a lot of kids had Gilbert Chemistry sets that came complete with instructions on how to make gunpowder and that's what we did. A kid could walk into a hardware store or drugstore and buy different chemicals and compounds and no one batted an eye. It was a normal thing for kids to do in that era.

We drilled a small hole in the back end of the pipe and used fuses from a prank firecracker that was sold in corner stores, 5 and 10 cent stores, etc. The firecracker was an empty red tube that came with 3 or 4 nice fuses.

The guns worked pretty well too and made a satisfying noise. No adult ever challenged us on what we were doing even when they saw us pulling our howitzers around. As long as we didn't shoot out windows or put a BB in an eye we were left to our own devices.
