By Saul Kaplan: As a tech junkie and geek wannabe I’ve been paying attention to 3D printing and the exploding maker movement. When I say paying attention, I mean reading about it, watching hackers and hobbyists make stuff, and wondering if there is more to the technology than the brightly colored plastic tchotchkes cluttering my desk. 3D printing really hasn’t affected me yet. That is until I recently chipped a tooth and had no choice but to visit my family dentist. It was the dentist’s chair that more than any article or demo converted me to the potential of 3D printing. Sometimes disruption has to hit you right in the mouth before you pay attention.
