Latest Patents

One of his latest patents is titled "System and method for roll-to-roll film tensioning for reduced separation force during bottom-up stereolithography." This patent describes a tensioning system designed for use in stereolithography manufacturing applications. The system includes a build plate that supports a three-dimensional part formed using photo-responsive resin, along with a base plate and a release element. The release element is configured to receive a quantity of photo-responsive resin for forming a new material layer. Tensioning components are secured to opposite ends of the release element, applying controlled tension during the peeling process to reduce the separation force required to detach the release element from the cured material layer.

Another significant patent by Hongtao Song is "System and method for liquid crystal display system incorporating wire grid polarizers for large scale and large volume stereolithography." This patent relates to a liquid crystal display (LCD) system that includes a light source generating unpolarized light and an LCD screen positioned in the path of this light. The system features first and second wire grid polarizers, each containing a plurality of nano-scale wires with differing polarizations. These polarizers create a 2D light mask that is suitable for initiating the polymerization of an optically curable material.
