ARDEC Engineers Using 3-D Printing To Revolutionize Shaped Charge Explosives. The AP (7/31, Ernst) reports that researchers at the US Army Armament Research, Development, and Engineering Center believe that 3-D printing ?will present security experts and policy makers with capabilities previously unimaginable.? The AP quotes James Zunino, materials engineer with the center, saying, ?Once you get into detonation physics, you open up a whole new universe.? The piece reports that Zunino?s work ?involves figuring out how different layers of explosive material can be packaged in new shapes to get a very specific result.?
