The "Plastikov" 3D printed AK reciever

but can we print the receiver, drill a piece of rebar for the barrel in .22lr, EDM the rifling, and make it giggle-worthy?
 
FA 22lr sbr would, of course, be as giggly as a team of middle school cheerleaders.
My son does a decent job with the factory trigger in my 15-22 SBR...

 
I've been on the fence with a printer for a while. Maybe we need a 3D printer thread with pros and cons for those that made the leap already...
 
There's alot of difference in a 3d printed AR lower that really doesn't see much of the recoil force (except the receiver extension threads) and an AK reciever that recieves 100% of the recoil on the trunnion rivets (in plastic...).

Think I'll pass until they sell 3D printers that use sintered metal. But it's a cool thing. Bending flats are so easy nowadays with the jigs out there. How many people have headspaced an AK on here?

Several places online are offering populated, headspaced, barreled kits.

It would be interesting to see if you could spread some force out over an entire printed receiver using metal reinforcing strips. A lot of the AR polymer receivers ended up having to do something similar around the threads for the receiver extension. Maybe print it so that it can accept some metal braces, then pour epoxy over to join everything nicely?
 
Question:

could you do this then use that to make a mold and do metal/aluminum casting?
I think it would be difficult, and you'd still have to drill holes and do some finish work. Probably easier to actually make an 80% AK receiver at that point.

Right now this is a "can we do this?" sort of proof of concept. 3D printing is really in it's infancy, but as time moves on and technology improves/cost decreases this is going to be a big deal. To control guns, they're going to have to control information.
 
Since AK receivers are pretty much slab sided and square, it should be pretty easy to cut and drill some metal flashing to mount on the sides and bottom as a reinforcement. Attach it with a strong epoxy, and maybe some screws here and there.

I'm really happy to see all the gun designs coming down from the 3D printer gun guys. Sometimes I get tempted to try my hand at it.
 
Mine is a super cheap one. I think a Longer LK4, but it works pretty good for what it is.
 
I've heard stay away from the hobby brand ones. Dremel in particular makes one that is super proprietary and you have to buy only Dremel brand filament or some such.
