旋转轴上三维打印的三角网格剖分与轮廓构造
Triangle Mesh Slicing and Contour Construction for Three-Dimensional Printing on a Rotating Mandrel
摘要：
三维（3D）打印是工业和生物医学研究中的强大开发工具。增材车床3D打印是3D打印的新兴子类，其中材料从旋转圆柱形芯轴的表面向外分层。虽然已建立的增材制造技术已经开发出强大的刀具路径生成软件，但迄今为止的增材车床出版物已被降级为最基本的概念验证结构。本文详细介绍了一种用一系列同心、开放、直圆柱体切割三角形曲面的方法的理论和实现，该方法是用加法车床技术创建刀具路径以打印复杂模型的关键步骤。有效的边缘的情况下，必须解决时，实施一个圆柱形切片机，以产生不相交的封闭轮廓详细描述了两类结果封闭轮廓。在完全实现能够将复杂几何形状从数字模型打印到旋转圆柱表面上的机器之前，需要用于生成填充图案、支撑结构和用于刀具路径构造的其他考虑因素的方法。这项工作代表了对同心圆柱体三角形网格切片的数学和算法实现的第一次彻底检查，并为添加车床型3D打印机的刀具路径生成的未来工作提供了见解。
英文摘要：
Three-dimensional (3D) printing is a powerful development tool both in industry, as well as in biomedical research. Additive-lathe 3D printing is an emerging sub-class of 3D printing whereby material is layered outward from the surface of a rotating cylindrical mandrel. While established additive manufacturing technologies have developed robust toolpath generation software, additive-lathe publications to date have been relegated to the most basic of proof-of-concept structures. This paper details the theory and implementation of a method for slicing a triangulated surface with a series of concentric, open, right circular cylinders that represents a crucial step in creating toolpaths to print complex models with additive-lathe technology. Valid edge cases are detailed which must be addressed when implementing a cylindrical slicer to produce non-intersecting closed contours; two classes of resultant closed contour are described. Methodologies for generating infill patterns, support structures and other considerations for toolpath construction are required prior to full implementation of a machine capable of printing complex geometry from a digital model onto a rotating cylindrical surface. This work represents the first thorough examination of the mathematics and algorithmic implementation of triangle mesh slicing with concentric cylinders and offers insights for future works in toolpath generation for the additive-lathe type 3D printer.
