Teaching how evolution works.
3D printers are a safe way to introduce bits to atoms paradigm shift. Long before desktop nanotech fabrication systems arrive with all the potential dangers they entail, getting society used to the idea of just how much can be done will do more than any amount of one to many teaching seminars of lectures. Open a 3D printing shop in your neighborhood. Offer the services for a nominal fee. Offer assistance to anyone want to make their own 3d Printer. It won't completely decentralize manufacturing, but it will get people thinking in the right direction.
Hopefully by the time mature nanotech is available to our 3dPrinters the memes of perfect recycling and a world not based on scarcity but who can make the winning designs will be etched in our brains.

Apparently it cuts off if you are watching it in full screen mode. This is the second TED talk to exhibit this.

A reply on Talk: Marcin Jakubowski: Open-sourced blueprints for civilization
I think there's a T.E.D. talk in there.
A comment on Talk: Anthony Atala: Printing a human kidney
One should expect that the cells being cultured could also receive enhancement therapy while they are being amplified. The cones cells for my replacement eyes could be tweaked to include UV perception and/or increased visible light color differentiation by having more pigments than just RGB. While they are at it, print the retina so that it isn't inside out - so no blind spot!
Futuristically, one can imagine printing silicon robot guardians next to each cell so that the authorities could shut parts of you down at will or to terminate you if necessary. Or maybe you could use them to interface with the internet.
