The Invisalign is a great, nearly imperceptible alternative to traditional braces — but getting them can cost thousands of dollars. Digital design major Amos Dudley came up with a different solution: He has been straightening his teeth with clear braces that he made himself, using a 3D printer. For 16 weeks, Dudley has worn custom trays of his own design to fix his teeth — and all for the cost of $60. It’s pretty ingenious, and the results are on par with anything you’d see from an orthodontist. See more of his story (and his incredible results) below.
