3D Printer can make Braces for Teeth

A Tennessee business is building 3D printers that fix crooked teeth. Chattanooga’s iPrint 3D builds a system of software, a facial scanner and a 3D printer. It lets an orthodontist size up a patient’s mouth, straighten a virtual version of their teeth on the computer, then print out a set of aligners that progressively fix the client’s teeth.
A client with crooked teeth can show up at an orthodontist’s office at 9 a.m., get a high-tech exam and walk out the door 90 minutes later wearing a set of “invisible” plastic braces, known as aligners, churned out by a 3D printer.
