I was wrong on that date. It was introduced in 1964. It was the little brother to the Ruger 44 Carbine that came out in 1959.

Here’s a guy who made a gun from a shovel: http://www.northeastshooters.com/vbulletin/build-yourself/179192-diy-shovel-ak-photo-tsunami-warning.html
No printer needed :)
Or a crook uses one to mug somebody and the somebody finds out and sues Kinko’s.
Whoever put me on this “3-D Printer Ping!” list, please take me off. I’ve had to use these stereolith systems for he past 15 years. Being on this list is too much like being at work. Please take me off your ping list.

Ar-15 and M-16 lowers are made from aluminum. Much easier to cast that steel.
You are soooooo outta here! (BTW youse guys hiring?)
LOL. Perhaps I was little harsh...
Yes, the early materials were somewhat to very expensive.
Yes, many of them are still difficult to recycle.
But today you can make serviceable filament from discarded soda bottles. There’s even a guy selling a bench-top shredder and extruder for that purpose.
Today the pallet of available materials is vast and the processes allow considerable variations in feedstock. One could tune their machine to make serviceable lost wax masters from ordinary paraffin or bee’s wax instead of the specialty waxes formulated for jewelery use.
Sintered powder machines can recycle all the unsintered material, with the only caveat being that the must be sieved to remove any damaged or stuck together grains. (and that you have to be careful to not mix differing formulations.
Like any other technology costs drop with experience and volume. You need to run as fast as you can just to stay caught up!
Right now? An opportunity to improve upon the existing technologies in both the RP and ordnance fields.

Have you seen this? I would like to attend.
