“3D-printed toothbrush scrubs chompers in 6 seconds”

Here’s a 3D-printing application I really didn’t foresee. It looks interesting, but at those prices, it’s going to be a long time before it catches on.

Now, when someone invents a machine that scans your mouth and produces one of these in a few minutes for $10 or less, and puts it in Wal-Mart stores everywhere… well, the traditional toothbrush might just have to go looking for another job. 🙂
