    Abstract: PROBLEM TO BE SOLVED: To make high resolution objects by stereolithography utilizing low-resolution materials which are limited by their inability to form unsupported structures of required thinness and/or their inability to form coatings of a required thinness. SOLUTION: Data manipulation techniques, based on layer comparisons, are used to control exposure in order to delay solidification of the material on at least portions of at least some cross-sections until higher layers of material are deposited so as to allow down-facing features of the object to be located at a depth in the building material which is equal to or exceeds a minimum cure depth that can effectively be used for solidifying these features. Similar data manipulations are used to ensure a minimum reliable coating thicknesses exist, above previously solidified material, before attempting solidification of a next layer. In addition, horizontal comparison techniques are used to provide enhanced cross-sectional data for use in forming the object. COPYRIGHT: (C)2006,JPO&NCIPI

    Abstract translation: 要解决的问题：通过使用低分辨率材料的立体光刻技术制造高分辨率物体，这些材料受到不能形成所需薄度的无支撑结构和/或不能形成所需薄度的涂层的限制。 解决方案：基于层比较的数据处理技术用于控制曝光，以便在至少一些横截面的至少部分上延迟材料的凝固，直到沉积更高层的材料以允许下降 物体的位于构造材料深度处的特征，其等于或超过可以有效地用于固化这些特征的最小固化深度。 使用类似的数据操作来确保在尝试凝固下一层之前存在最小可靠的涂层厚度，以上固化的材料。 此外，使用水平比较技术来提供用于形成物体的增强的横截面数据。 版权所有（C）2006，JPO＆NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide techniques for improving manufacturing system and method of a component in reliability and precision (with little curl or subsequent distortion) in the case of forming a three-dimensional object of stacked layers by applying stereo-lithographic mechanism. SOLUTION: Data manipulation techniques, based on layer comparisons, are used to control exposure in order to delay solidification of the material on at least portions of at least some cross-sections until upper layers of material are deposited so as to allow down-facing surface of the object to be located at a depth in the building material which is equal to or exceeds a minimum cure depth that can effectively be used for solidifying these features. Similar data manipulations are used to ensure that a minimum reliable coating thickness exists, above previously solidified material, before attempting solidification of a next layer.
