Amos Dudley didn’t used to smile very much. For years he’d been self-conscious of his teeth and he avoided showing them as much as possible. But after deciding to use a 3D printer to make his own braces, He now most definitely has something to smile about.

Amos, a 23-year-old Digital Design Student at New Jersey Institute of Technology, came up with the idea while researching braces on the internet. Realizing that a lot of them looked like something he could print, the student set out to put his idea to the test.

After extensively researching how to formulate teeth realignment calculations, Amos eventually made 12 sets of braces. And as you can see from the pictures below, it looks like his crazy idea has worked. The whole project cost less than $60, which is considerably less than the thousands he would have had to spend on orthodontist costs. But despite his success, Amos doesn’t plan to make a career out of it.

“I think there’s too much liability,” he told CNN. “I’m not interested in orthodontics. It was more of a hacker project than making a business out of this.”
