Abstract: 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.

Abstract: The present disclosure relates to a liquid crystal display (LCD) system. The system in one example has a light source for generating unpolarized light, and an LCD screen arranged in a path of transmittance of the unpolarized light. First and second wire grid polarizers are arranged adjacent to the LCD screen and each have a plurality of nano-scale wires, with the first and second wire grid polarizers have differing polarizations. A pitch of each of the nano-scale wires is no larger than one-third a wavelength of the unpolarized light from the light source. The wire grid polarizers create, in connection with operation of the LCD screen, a 2D light mask suitable for initiating the polymerization of an optically curable material.
