3D printer
Cool. The minute someone makes a working gun with one, though, they’ll be regulated.
Remember, I do this to entertain me, not you.

Oh please, you can make a pistol with a 3-axis mini-mill. And even a full on CNC conversion of said mill would require less than $2k. Why would I require a $17k 3D printer that only makes things in plastic?

The Fab@Home project is an opensource version of the same sort of thing. Checking their FAQ page puts the current estimate for building your own at $1,300 so ‘ease of use’ seems to carry a pretty hefty price tag.

I’m willing to be the HP unit will beat the operating tolerances of the Fab@home by a large margin. That’s where the serious $ comes in.

Metrix Create Space, in Seattle, has three or four 3d printers you can rent. They all cost on the order of $2000 a pop.
also, you can easily print an ar15 lower on one. I’ve considered having an ar15 lower cut out of birch plywood on the laser cutter.

Check out your local hackerspace for all your CNC, 3D printing and laser cutting needs.

Jeff – it is so that you can make a Glock 7 and not worry about metal detectors…lol

The home-brew 3D printer machines are available in kit form for under a kilobuck. The cost cam be even half of that if you want to pick and chose your own parts from a number of suppliers instead of an all-inclusive kit. It won’t print quite as nice as HP, but you’ll save a bundle on consumables alone, and no solder-fu is needed.

AFAIK, no one has uploaded digital 3D printer files for any kind of a weapon, but I’ll have some reloading die boxes and cartrage tray objects uploaded at some point.

Ry: Yeah, but will the ABS it extrudes be strong enough to actually work as a lower (and, almost as importantly, even if it works immediately, will it keep working after a few thousand rounds of wear and stresses)?
I know that plastics of some sort can work (see CavArms lowers), but those are glass-filled nylon, not ABS.

The day they regulate these is when both the first and second amendments die.
Think of it this way: what is the gun? Is it the plans for it, or the device for manufacturing it? No, but once these techniques are viable for making a gun, both must be controlled.
Actually, this is a good thing – pretty soon you can buy a CD with the plans to make spare parts for any firearm ever made, Lock, Stock and Barrel. Fire up the CNC machine, and away we go – we will never be disarmed.
For metal parts, print stuff in wax, cast it via lost-wax method, and you’re good.

does anyone know anyone who has one of these 3d printers? what are they using it for? The perfect spork? 🙂
