  • Rapid and accurate production of stereolithographic parts
    Patent number: 5610824
    Abstract: A stereolithography system employing a more powerful laser and faster dynamic mirrors to speed up part building without sacrificing accuracy is described, especially large or complex parts. A controllable shutter is placed in the beam path of the laser to selectably block the passage of the beam and prevent unwanted solidification. A suitable servo controlled feedback loop is provided to accurately position the mirrors at the higher velocity. Also described is a means to reduce data flow by distributing tasks in a multiple processor environment, and to improve user interaction by the use of a spreadsheet model. These also improve the speed of part building, especially for large or complex parts.
    Type: Grant
    Filed: January 25, 1993
    Date of Patent: March 11, 1997
    Assignee: 3D Systems, Inc.
    Inventors: Wayne A. Vinson, Frank F. Little, Wolfgang Schwarzinger, Mark A. Lewis, Yehoram Uziel, Robert T. Pitlak, Stuart T. Spence
