New Method of Polar Coordinates Optimization of CAD Model Slice Profile for Additive Manufacturing

Based on the analysis of the present situation of 3D CAD model layering for additive manufacturing at home and abroad, a new polar coordinate optimization method for adjacent layer profiles is proposed. The optimization method is elaborated in detail, and the optimization of 3D model slice contour is analyzed through the example verification. On the basis of optimization, the 3D CAD model error can be reduced, so as to provide a reference for improving the accuracy and reducing the error of parts in additive manufacturing.
