You may know about 3D printed weapons like the Liberator, and how much of a stir they have caused around the world, leading to the Australian Congress sitting for weeks, as well as the arrest of a Japanese man.
There are many other related incidents, but public opinion still hasn't really taken a stand for or against 3D printed weapons.
The latest development is that these weapons now have special bullets made exclusively for them. Until now, most tests resulted in the weapons breaking after many shots.
Michael Crumling, a 25-year-old engineer from Pennsylvania, has developed a new type of bullet specifically for printed plastic guns, which features a thicker steel shell encasing a regular lead bullet. The shell acts as a buffer in the plastic gun, significantly reducing the pressure, as in a test in which the gun was fired 19 times, no visible damage was seen.
