A colleague at work has gotten a 3D printer. It's convinced me I could do good things, provided I spent all the time I spend on making & painting my minis, on learning how to use a 3D printer to best effect. Which seems slightly self-defeating, for me anyway.
When we can get a BT-scale vehicle printed for a couple of bucks by a third-party provider, at suitable resolution for tabletop use; when you could get your 3D terrain, or Heroscape-style hexes, printed for less than the cost of buying them commercially, the millenium will have come.
I'm loving watching those who have more time, or more interest in the 3D printers, doing wonderful things.
