3 3 SYSTEM AND METHOD FOR DECREASING TIME FOR PRINTING LAYERS IN THREE-DIMENSIONAL OBJECTS AND FOR ENHANCING COLOR FIDELITY AT THE SURFACE OF THREE-DIMENSIONAL OBJECTS

摘要

The three-dimensional object printer has a controller that generates objects with different color saturation by operating a plurality of ejectors that eject drops of different materials having different colors, with at least one color being white. The controller calculates a function of the sum of the average number of drops per voxel in each layer, the target value of the average number of drops per voxel of the non-white pigment in each layer, and the distance from the nearest surface of the object for each material injected by the ejectors. With reference to operate a plurality of injection machines. Above a predetermined distance from the nearest surface, the controller operates a plurality of ejectors to form voxels in the object hierarchy with only transparent and white drops. At a distance less than a predetermined distance, the number of transparent drops increases and the number of white drops decreases.
