This is something that has hit my consciousness only recently as a result of the gun debate (3-d printers are being used to manufacture magazines). Since then I have checked out some uses for it on YouTube and have seen everything it used to manufacture model airplanes that fly to hand-grenades (yikes!). I have already been pricing out units myself and would like to purchase one of these one day in the not-so-distant future. The change that this technology will bring to so many individuals around the world is nothing short of revolutionary. I believe that it will really impact our society over the next decade in ways we would not even realize yet- kind of like the Internet did in the 1990's.
