This college student 3D printed his own plastic braces for $60 - and they actually fixed his teeth

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.

On his blog, Dudley writes that he was an unlikely combination of two things: he was broke, but had access to a high-quality 3D printer through his university. He took full advantage of this.

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.

And it was worth it for Dudley, whose smile turned out looking remarkable.

Here is the process he went through:
