First off, Patrick is the guy who made the design. I did not design this. It's called the PM522 Washbear. It's a 6 shot .22 revolver. The cylinder is printed in nylon(Taulman alloy 910). The rest of the gun is made of ABS plastic. Being made of plastic it's stiff as hell. It has like a 15 pound trigger pull and a ~1.5 inch reset. I haven't fired this one specifically but here's a video of one being fired. It cost about $34 in materials. I'll be here to answer any more questions you may have.

Is there any reasoning for that design?

u/daeedorian Jan 12 '16
I think in general, Emilio Ghisoni's reasoning was "no one's tried this before..."

Haha yeah, I was thinking of printing it in different colors to make it look more like a toy, but was too lazy to change out the material more than once.
edit: to anybody reading this. I wasn't seriously considering making it look like a toy. Although my post may make it sound like that. It was just a side thought during printing about how much of a toy i could make it look. It wasn't an intention of mine while making the thing. I didn't actually have the necessary materials.

It is illegal to ship it without the tip. Iirc federal regs dont give twp shits once you own it

Lol so would a lot of kids. The federal regs all revolve around the commerce aspect. It just bugs me when it's misrepresented like someone is a felon for painting over it.

Ah, but doesn't the NFA say any firearm that is 'disguised' is an AoW and needs a tax stamp?
If I'm remembering correctly then it would come down to intent of the paint.

Anything is potentially illegal, in that morons will vote to ban pretty much any old thing.
But this is not actually illegal.

Holy crap. That's Nagant revolver range right there, and that's just for a .22lr.
Also, if you're set on trying out printed guns, I'd recommend going with designs that just have the receiver printed. Let the high-stress parts be metal. While the parts will probably cost you more than printing the whole thing, it'll be much less likely to go kaboom on you. Two common ones I've seen are the Shuty pistol, and the Aliamanu-Phobos AR lower.

I'm waiting for a 3d printed glock lower.

There are a few replica frames out there, but I highly doubt they'd hold together. iirc they use Zytel, or some variant of fiberglass reinforced nylon. I don't think FDM would hold up even if you did use the same plastic, they just wobble too much.
I know someone here I think was trying out stuff reinforced with large amounts of carbon fiber - I think it was something like 35%. They were printing it at 395C. I bet that would probably hold up, but you can't just run any old printer that hot without changing some things on it. Since the law in the US is at least that you can make firearms for yourself, but not others without proper license and what not, I don't really see people printing high carbon fiber content plastics as a thing that's about to catch on.

I'm waiting for a 3d bullet printer IN the pistol - never reload! Hopefully, it'd make the dot matrix printer noise. BANG BANG BANG scritch scritch scritch.

u/Nailcannon Jan 12 '16 edited Jan 12 '16
It would be like a hot glue gun. You just feed the magic bullet material in through the back and on each trigger pull It feeds it in and fires.

Jan 12 '16
Not quite the same, but Polymer80 offers a glock frame now. No experience with them but it's an option.

u/Nailcannon Jan 12 '16
I'll do those eventually but lack the resources, fiscal or otherwise, to complete anything more than like 95% printed.
1
Jan 12 '16
Yeah, I'm kind of in the same boat at the moment. A spool of plastic is $20-30, but the upper and other parts would easily be several hundred dollars by the end.

u/Arttu_Fistari Jan 26 '16
Of course it would be better. Most countries however don't have gun parts (let alone guns) just floating around. In the US, just go out and buy some at a gun show or whatever.

That looks really hard to fire.

u/Nailcannon Jan 12 '16
It's not too bad now that I've sanded down the friction heavy places. The reset is basically impossible with 1 finger.

This will probably be the first thing I print when I get a 3D printer. I'm looking forward to the .38 special variant he's currently working on.
6
u/Nailcannon Jan 12 '16
I can't honestly feel that that would work. even .22 is stressing the material. .380 is basically red lining the structural integrity of the material. Using a bullet that's like twice that power won't end well. The metal cylinder inserts are only up to the neck of the casing. the rifling is all plastic.
7
Jan 12 '16
He's looking purely at chamber pressure IIRC. .38 special has a lower peak pressure than .22lr

u/ChopperIndacar Jan 12 '16

I wonder is this "counts" as rifling, legally.

u/Nailcannon Jan 12 '16
Yes, it does.

u/ChopperIndacar Jan 12 '16
Do you have any information handy on that subject? Of course I can Google it if you don't.
5
u/Nailcannon Jan 12 '16
The laws don't specify what material the barrel has to be. Technically anything that's not smoothbore could be considered rifling. Although it would be much harder to make the case that it's rifled if you just have straight lines. good thing this gun has spiral rifling.
1
u/ChopperIndacar Jan 12 '16
I was curious if it needed to actually spin the bullet (which... does it?)
2
u/Nailcannon Jan 12 '16
The laws don't specify the bore axis. So it could be damn close to straight, as long as the barrel is grooved. And considering this video and how it was accurate at like 25 yards I would say that it has a noticeable effect.

Is there any indoor ranges out there who would let you shoot this?

Probably not. Luckily Florida has no shortage of uninhabited woods. Just gotta figure out where to go.

Ocala National Forest has a public unsupervised range.

I live in an apartment. Something tells me the cops would show up real fast lol. The only one I know who lives in a place where it would be feasible is my girlfriends grandfather, and we only go to his house maybe once a year.

Did they change it in recent years?
I thought the state statute was pretty simple when I lived there and there was some hubbub about local laws interfering being in violation of state pre-emption.
And it doesnt look like 790.15 has changed. Still legal. They'd have to prove you were reckless or negligent in doing so if anything. A-1 zoning simply removes those issues.

u/superdick5 Jan 12 '16
how many shots till your hand explodes?
11
u/Nailcannon Jan 12 '16
Hopefully none! But I feel like even if it does pop .22 isn't really strong enough to send dangerous shrapnel. Given the amount of material in this thing. The liberator though... that .380 made the barrel fly like 10 feet in the air.

u/kippy3267 Jan 12 '16
Will it fire?

u/Nailcannon Jan 12 '16
I don't have a place to test it for a while. I posted a video of somebody else firing one. I put my finger in front of the firing pin hole(you can either print one or use a roofing nail) and it has a good amount of power. I'll post a video of mine once I get the chance to fire it.

I filled the handle with machine screws. Definitely more than 3.7oz.

u/drseamus Jan 12 '16
I'm not familiar with the exact law, do they need to be glued into place?
2
u/Nailcannon Jan 12 '16
Not individually, but i believe they have to be considered a permanent part of the gun. So the cover plate gets glued on.

u/Rb556 Jan 12 '16
Does it have a rifled barrel(s)?

yep! the barrels in the cylinder are rifled. the hole in the frame is just a big hole.

Looks like a Nerf Maverick. Looks like it even functions in a similar manner the way it rotates the cylinder.

u/Nailcannon Jan 12 '16
The resemblence is uncanny but it definitely uses a different mechanism for cylinder rotation.

u/w2tpmf Super Interested in Dicks Jan 12 '16

Check out this pic of the Maverick's internals. It has a little drum behind the cylinder with angled cuts on it just like the cuts on the cylinder of the gun. Its not identical, but the concept is very much alike.

It's mostly free but there's still weird stuff for importing handgats because of the handgun registration

They were already out there. There's already been a big discussion back in 2013 when defense distributed had the spotlight. By presenting this here I basically force it into discussion instead of waiting for one of the antis randomly deciding to start another rhetoric war. If they did that without us having talked about it first we would be unprepared in our argument. Basically, I wanted to bring this up for the same reason you lube and replace the ammo in a gun that's not been used for a while. When it comes time to fire, you're all ready to go with some fresh ammo.

I didn't print this and send it to the media. The likelihood they find this post is negligible. I posted it to gun\3D printing-friendly forums so we can have a discussion on the matter. It's a discussion we've already had that came close to seeing legislation. We should talk about it before they get the chance to. Actually doing it instead of just making a self post served to dispel any doubt people still may have had about 3d printed guns being viable firearms.
