    摘要: 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.
