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.

摘要： A method of manipulating data in a method for forming a three-dimensional object layer by layer from an ink jettable, solidifiable material by providing data corresponding to a plurality of polygons defining the outer surfaces of a plurality of three-demiensional objects and providing sets of x, y, and z coordinates corresponding to each layer and identifying x and y coordinates with each z coordinate such that directional values and counter values are determined for each y coordinate in a first set of coordinates generated. A second set of y coordinates are generated according to a formula that permits the determined layers to be processed to form a three-dimensional object.
