I'm pretty excited about 3D printing and the amazing inventions it's sparking. But none are quite as odd as the Blizzident personalised toothbrush.
Experts take a scan of your teeth, then 3D print a mould, like a gumshield, filled with bristles. You pop it in your mouth, move your jaw around and, hey presto, in six seconds your teeth are clean.
It's a tad pricey at £250, but a wonderful example of what designers and engineers can create with 3D printing technologies.
The exhibition 3D: printing the future launches at the Science Museum on 9 October 2013.
