One of the most promising applications of 3D printing is the customization of everyday objects to the most personal and variable thing we possess—our bodies. A new example of this is the Blizzident toothbrush, which is made possible by two intersecting technologies—3D scanning and 3D printing.
The result is a toothbrush shaped exactly like your teeth. You simply bite it, chomp for six seconds, and voila: every single one of your teeth is perfectly brushed in both an up and down and side to side motion. Or so, at least, it’s claimed.
