No, not the Lexmark that ThreedleDeedle uses to print his fave gay anime porn, the 3-D printer used to produce this:
Solid Concepts, based in Austin, used a laser sintering process to print a version of an M1911 .45 caliber pistol.
But the real goal was to show that 3-D printing metal is precise enough to produce parts within specific tolerances and strength.
With this gun, the only parts not made with a 3-D printer were the springs.
