Tsukulus Co. of Japan now offers figurine printing at their Akihabara location in Tokyo. Their ZCorp 450 can punch out figurines based on your own designs. Prices for a typical figurine are 8000 yen, or a little over USD$80 each.
This seems like the right thing to do, since the "Akihabara Electric Town" area or Akiba as the locals call it, is a hotbed of electronics sales where many new products first emerge.
It's not clear whether pre-designed figurines are selectable, as other figurine shops do (e.g. FigurePrints, Fabidoo or even Ponoko). This may be a barrier to their progress, or an opportunity to expand sales to those unable to develop their own designs.
Time will tell if Otakus discover 3D printing.
