Traditional 3D printing is based on stereolithography or standard tessellation language models, which contain many redundant data and have low precision. This paper proposes a slicing and support structure generation algorithm for 3D printing directly on boundary representation (B-rep) models. First, surface slicing is performed by efficiently computing the intersection curves between the faces of the B-rep models and each slicing plane. Then, the normals of the B-rep models are used to detect where the support structures should be located and the support structures are generated. Experimental results show the efficiency and stability of our algorithm.

直接在B-rep模型上生成切片和支持结构以进行3D打印

传统的3D打印基于立体光刻或标准镶嵌语言模型，这些模型包含许多冗余数据且精度较低。本文提出了一种直接在边界表示（B-rep）模型上进行3D打印的切片和支持结构生成算法。首先，通过有效地计算B-rep模型的面与每个切片平面之间的相交曲线来执行表面切片。然后，使用B-rep模型的法线来检测支撑结构应位于何处并生成支撑结构。实验结果表明了该算法的有效性和稳定性。
