(54)MODIFYING ADDITIVELY MANUFACTURED PART DESIGNS USING TOPOLOGICAL ANALYSES


(57) Set differences between an as-designed and an as-manufactured model are computed. Discrepancies between the as-designed model and the as-manufactured model are determined based under-deposition and over-deposition features of the set differences. Based on the discrepancies, an input to a manufacturing instrument is changed to reduce topological differences between the as-manufactured model and the as-designed model.
