Abstract Ceramic 3D printing has gained rapid development in recent years. Especially, desktop ceramic 3D printers get more and more popular for designers, artists, and makers to work with clays. As a highly viscous pseudoplastic liquid, the printing material clay produces featured aesthetics, and also indicates several manufacturing constraints. There are barely customized modeling tools for ceramic printing. Targeting for ceramic printing, we present a user-interactive modeling and fabricating framework using sweeping lines as the design tool. We integrate the ceramic printing constraints like self-supporting and collision-free in the modeling stage. Then we propose a customized method for generating the printing file, with the guarantee that the extruder traces a single continuous path without starts and stops. To fulfill this goal, we compute an adaptive zig-zag path along the sweeping surface. During the fabrication, our continuous path avoids the potential collision between the printing head and the physical model. Moreover, we optimize the extrusion amount along with the extruder movement, such that overlap between neighboring layers is appropriate in terms of both model stability and cost-effectiveness. We demonstrate the fabrication process and physical results to validate our method.

陶瓷 3D 打印清扫面

摘要 陶瓷3D打印近年来得到了快速发展。特别是，桌面陶瓷 3D 打印机越来越受到设计师、艺术家和制造商使用粘土的欢迎。作为一种高粘性的假塑性液体，印刷材料粘土产生了特色美感，同时也表明了一些制造限制。几乎没有用于陶瓷打印的定制建模工具。针对陶瓷印刷，我们提出了一个使用扫掠线作为设计工具的用户交互建模和制造框架。我们在建模阶段集成了陶瓷打印约束，如自支撑和无碰撞。然后我们提出了一种生成打印文件的定制方法，保证挤出机跟踪单个连续路径而无需启动和停止。为了实现这个目标，我们计算沿扫描表面的自适应锯齿形路径。在制造过程中，我们的连续路径避免了打印头和物理模型之间的潜在碰撞。此外，我们随着挤出机的运动优化了挤出量，这样相邻层之间的重叠在模型稳定性和成本效益方面都是合适的。我们展示了制造过程和物理结果以验证我们的方法。
