3D printing plastic braces for $60

An undergraduate at New Jersey Institute of Technology made his own plastic braces using a 3D printer, $60 of materials, and a healthy dose of ingenuity — and they actually worked.

Amos Dudley had braces in middle school, but he didn't wear a retainer like he was supposed to, so his teeth slowly shifted back. He didn't want to shell out thousands of dollars for a whole new round of braces, so the digital-design major decided to make his own.

The process wasn't exactly easy. He had to research orthodontic procedures and plot the route of his successive braces, so his teeth would move in the right way. But once that was done, all it took was fabricating a series of models out of relatively inexpensive plastic, and then following through on wearing them.

If you want a more in-depth look at the process, check out Dudley's blog. (Just don't ask him to print any braces for you.)
