IMR

3D-Printer Rifle is a fictional weapon making an appearance in the upcoming game Call of Duty: Advanced Warfare.

Description
Apparently from what has been announced on gameinformer.com, Sledgehammer is tapping into relevant modern 3D printer technology for this weapons inspiration, looking far into the future to see what might be possible on the battlefield. Players load in a canister of liquid matter and rack it by pulling back on the bolt. Once securely housed, the internal computer begins printing ammunition on the spot. Players can see the number of bullets created as a digital ammo counter increases. Sledgehammer is still tinkering with the fire rate and power of the 3D printer rifle, but it should dramatically reduce reload time.
