    摘要： The invention encompasses compositions and methods for designing or producing three-dimensional articles layer-by-layer, whereby the specific approach to build-up a region of a single layer by fusion, deposition of material, or other path-based process or non-path process that creates track-like geometries requires either differing track or track-like geometry, or track or track-like geometry printing parameters, within a region of a single layer or within adjoining regions of multiple layers, is disclosed. Employing this method, single layer or multilayer parameter-varying fusing and deposition strategies can be generated that reduce article fabrication time and improve article physical properties, in part by targeting a distribution of scan paths that satisfy covering problem overlap and/or dense packing criteria. Additionally, methods and compositions for designing or producing three-dimensional articles by altering the thickness of a material layer deposited during a print relative to the slice thickness or net displacement of a stage or of a material and/or energy-depositing print head, are disclosed. Employing this method can result in the reduction of article fabrication time and/or the improvement of printed article physical properties, where these results advantageous to printing are dependent on the print process, material properties, and feedstock properties employed during the print.

    摘要： Methods are described for creating a correspondence between percentages of a spot color and print material thicknesses. For example, a method can include printing a set of printed regions on a substrate, wherein each printed region is printed according to a different percentage of a selected spot color. The method can further comprise measuring the thickness of each printed region. The method can further comprise comparing the thickness of each printed region with a target thickness for the printed region. The target thickness for the printed region can be determined according to the percentage of the selected spot color used for printing the printed region. The method can further comprise, for each target thickness, determining an adjusted spot color percentage required to print a layer of structural print material having the target thickness.
