College student 3D prints his own braces




The digital design major has been straightening his top teeth for the past 16 weeks using clear braces he made himself.

"I'm still wearing the last one," Dudley told CNNMoney on Tuesday.
"The last one" refers to the twelfth and final straightening tray in his self-designed treatment.
Dudley said he had braces when he was in junior high, but he didn't wear his retainer as much as he should have, and his teeth shifted.
Over time, Dudley discovered that he wasn't smiling as much because he wasn't happy with the way his teeth looked.
