Publication number: 20220088868Abstract: The present disclosure relates to a tensioning system for use in a stereolithography manufacturing application. The system may have a build plate for supporting a three dimensional part being formed using a photo responsive resin, a base plate and a release element extending over the base plate. The release element is configured to receive a quantity of photo responsive resin for forming a new material layer of the three dimensional part. A pair of tensioning components are secured to opposite ends of the release element, and apply a controlled tension force to the release element during peeling of the release element to reduce a separation force required to separate the release element from the new material layer after the new material layer is cured.Type: ApplicationFiled: September 22, 2020Publication date: March 24, 2022Inventors: Eric B. DUOSS, James OAKDALE, Nicholas Anthony RODRIGUEZ, Hongtao SONG, Richard CRAWFORD, Carolyn SEEPERSAD, Morgan CHEN
