Abstract

This study proposes an efficient preprocessing method and parametric modeling technique for the path planning of corrugated curved surface sandwich structures. Focusing on the characteristics of Fused Deposition Modeling (FDM), the model undergoes preprocessing for two types of path planning, segmenting the sandwich structure for Eulerian Path Printing (EPP) and Eulerian Circuit Printing (ECP). Algorithms were developed using the SolidWorks API for secondary development, resulting in a standalone plugin module. This plugin streamlines adaptive modeling of corrugated sandwich structures on curved surfaces, showcasing strong versatility. Additionally, a comparison of the printing time between preprocessed models and standard models reveals a significant reduction in nozzle idle time. Moreover, as the infill density increases, the reduction in printing time becomes more pronounced. Finally, compression tests confirmed that printed parts obtained using the EPP and ECP methods maintained comparable mechanical properties to those printed using conventional methods.

曲面波纹夹层结构三维打印的高效参数化建模与路径规划方法

提出了一种有效的波纹曲面夹层结构路径规划预处理方法和参数化建模技术。针对熔融沉积建模（FDM）的特点，对模型进行两种路径规划的预处理，分割出欧拉路径打印（EPP）和欧拉电路打印（ECP）的夹层结构。算法使用SolidWorks API进行二次开发，从而形成一个独立的插件模块。这个插件简化了波纹夹层结构在曲面上的自适应建模，展示了强大的多功能性。此外，对预处理模型和标准模型之间的打印时间进行比较，发现喷嘴空闲时间显着减少。此外，随着填充密度的增加，印刷时间的减少变得更加明显。最后，压缩测试证实，使用EPP和ECP方法获得的打印部件与使用常规方法打印的部件保持相当的机械性能。

期刊介绍： Graphical Models is recognized internationally as a highly rated, top tier journal and is focused on the creation, geometric processing, animation, and visualization of graphical models and on their applications in engineering, science, culture, and entertainment. GMOD provides its readers with thoroughly reviewed and carefully selected papers that disseminate exciting innovations, that teach rigorous theoretical foundations, that propose robust and efficient solutions, or that describe ambitious systems or applications in a variety of topics. We invite papers in five categories: research (contributions of novel theoretical or practical approaches or solutions), survey (opinionated views of the state-of-the-art and challenges in a specific topic), system (the architecture and implementation details of an innovative architecture for a complete system that supports model/animation design, acquisition, analysis, visualization?), application (description of a novel application of know techniques and evaluation of its impact), or lecture (an elegant and inspiring perspective on previously published results that clarifies them and teaches them in a new way). GMOD offers its authors an accelerated review, feedback from experts in the field, immediate online publication of accepted papers, no restriction on color and length (when justified by the content) in the online version, and a broad promotion of published papers. A prestigious group of editors selected from among the premier international researchers in their fields oversees the review process.
