Honestly, the biggest thing holding 3D printing back seems to be lack of broad access to co-op hackerspaces with top-of-the-line machines. And I don't mean in SF. I mean in Small Town, Kansas, sponsored by the local high school, library, and whoever else. Buying one for home use is a dalliance for the upper middle class. But democratized access to technology would be far more effective. Sharing an actual structural, metal 3D printer seems so much more useful than having 20x plastic-only home machines.
