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.
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.

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