The barrel is the last sticking point for 3-D printed weapons. Plastic versions only last a few rounds at the most, as plastic tends to melt or char under the heat of a round firing. let alone the friction of the bullet in the bore.
Laser sintering 3-D printing machines aren't cheap - but they also aren't federally regulated - yet.
I wonder if an enterprising entrepreneur could buy one of these and offer time on the machine to citizens who want their very own one-off printed handgun?
