3-D Printer

Our technology commentator Rick Miller says 3-D printers are available in "box stores" for around $1,300, and a small hand-held 3-D printer that can render small, plastic figures is available for about $99.  There is concern that guns can actually be printed, but body parts such as hands and ears have also been produced with 3-D printers.  Rick offers this list of the 10 weirdest 3-D

I saw something online that fueled my natural pessimistic tendencies.  It was a story about a University of Texas law student who, on a computer, has developed a plastic gun whose parts can apparently can be fabricated using a 3-D printer (did you know there were 3-D printers?) and assembled as a gun that actually fires bullets.
