摘要：

To address the issue of low intersection efficiency in curved surface slicing of an STL model in additive manufacturing, this study proposes a novel curved surface slicing algorithm that integrates inner and outer bounding boxes with a projection-based approach. The proposed methodology is outlined as follows: Firstly, during the intersection process between the curved surface layer and the model, oriented bounding boxes (OBBs) are constructed for both the curved surface layer and the model to identify the intersecting regions, and the triangles located within the intersecting regions are sele...
