Amos Dudley, a student at the New Jersey Institute of Technology, created his own clear plastic retainers using dental molds, laser imaging, a 3D printer, and plastic molds. His description of the research and process [amosdudley.com] includes images of each step. After sixteen weeks, he was satisfied with the results and has received a deluge of inquiries. The Washington Post notes [washingtonpost.com] he only spent $60 on materials as he had free use of the college's equipment. Dudley, who will graduate this spring, is getting job interviews thanks in part to the attention the project has received.
