  • Publication number: 20220362971
    Abstract: A system including a container for holding a photosensitive medium adapted to change states upon exposure to a light source, an optical imaging system, configured to move above the container holding the photosensitive medium, and having the light source, and a control system configured to: slice a digital model of a three-dimensional object into a slice having a cross-section, generate a build cross-section by filling a two-dimensional image with one or more copies of the cross-section, add to the build cross-section a conformal lattice to fill space in the build cross-section around the one or more copies of the cross-section, and control movement of the optical imaging system above the container to cure a portion of the photosensitive medium corresponding to the build cross-section to produce a layer of a three-dimensional object.

  • Patent number: 10336055
    Abstract: Systems and methods for fabricating three-dimensional objects. The system includes an optical imaging system providing a light source; a photosensitive medium adapted to change states upon exposure to a portion of the light source from the optical imaging system; a control system for controlling movement of the optical imaging system, wherein the optical imaging system moves continuously above the photosensitive medium. The method includes moving a maskless optical imaging system providing the light beam in a continuous sequence; presenting the light beam on a portion of the photosensitive medium; lowering a plate upon which the photosensitive medium resides; and applying a new layer of the photosensitive medium.
