IMO, we are still a ways away from 3D printing being as disruptive as a lot of people think (at least for home use).

From owning a 3D printer and doing prints for friends in my engineering classes, I think people still greatly underestimate how high touch 3D printing is today.

For example, look at the makerbot google group: https://groups.google.com/forum/?fromgroups#!forum/makerbot

Even looking at Shapeways (an online 3D printing company with really expensive machines), they still deal with quality control problems for the average model someone uploads.
