Title:
MODEL OPTIMIZATION METHOD AND APPARATUS FOR ADDITIVE MANUFACTURING, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/126440
Kind Code:
A1
Abstract:
A model optimization method and apparatus for additive manufacturing, and a storage medium. The method comprises: obtaining an explicit model of conceptual design for additive manufacturing, and converting the explicit model into an implicit model (101), the implicit model being represented by a signed distance filed consisting of the shortest distance from each voxel to a conceptual design boundary point in a workspace; determining an infeasible geometric feature for current additive manufacturing and a detection threshold corresponding thereto (102); performing, on the basis of the determined detection threshold of the infeasible geometric feature, infeasible geometric feature detection and iterative processing for correction and optimization on the implicit model to obtain an optimized implicit model (103); and converting the optimized implicit model into an explicit model to obtain an optimized explicit model (104). The method can improve the efficiency and robustness of model optimization.
