Here's a new hobby idea for the hard-core 2nd-Amendment types, who

lust over loaded howitzers as lawn ornaments, and MANPADS for duck

hunting, etc.:

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."

If they could only 3-D print Plutonium...

It ought to be easy with these multi-nozzle printers. You just fill one hopper with electrons, one with protons and one with neutrons and have at it.

Wouldn't surprise me at all if, in a hundred or a thousand years, such a machine would actually exist.
