Like everything, 3D-printing has its good and bad things: it can also be used for malignant applications. The first 3D printed gun that can fire one bullet was a hot topic a couple of months ago. Now a 3D printed metal gun is created and it can fire a lot of bullets. I don’t think that this will be used by criminal organizations because it costs a lot to buy a 3D printer for metals. So the total cost will be cheaper to buy an ordinary gun.
