XKCD's 3d printing comic

XKCD addresses the inevitible future of 3d printing.

I admit, I wondered if people would start hacking into the networks of 3d-printing-enabled homes/businesses, and start printing things without permission.  The only thing that made me realize this future is unlikely, is that people haven’t been wardriving past 2d printers and sneaking documents and images to get printed out.  Probably because even the owners of 2d printers can’t get them working, 80% of the time!
