According to his blog, Dudley is a 24-year-old digital design student at the New Jersey Institute of Technology.
He told CNN Money that he had braces in junior high, but stopped wearing his retainers.
His teeth became crooked, and he said he realized last year he had stopped smiling because he was self-conscious about his teeth.
“I wasn’t smiling, and it was because I was unhappy with my teeth,” he wrote on his blog.
Dudley began researching clear braces online to fix his teeth when he noticed something: The braces he was looking at looked like something that could be made with a 3D printer, which he has access to as a digital design student.
