Health - If printing bone or at least better implants becomes acceptable this will be huge for the rising senior population.
Entertainment - With the rise of virtual worlds and video games, 3D printouts of your characters could seriously disrupt the action figure/ doll product categories which are worth about $4B/year. This assumes quality continues to improve.
But in the short term, the only place where this makes sense is for one off items, where it brings the cost of production down nicely. Just like FPGAs versus statically designed microchips (I'm not sure what the right word is for that), intersting niches will be advanced by printing, but advances in mass production probably will have more impact on global wealth.
Don't get me wrong - I'm going to be taking a holiday next year to build a reprap, so I'm a believer in this technology - I just think it'll be used in specific niches and by hobbiests for a long time to come.
PS - About Rock Solid, I'm cofounder and a developer, yes.
What is your affiliation with Rocksolid? Are you a Flash developer?
Coupled with nanotechnology this is seriously gamechanging stuff.
