摘要：

光固化3D打印技术作为目前较为成熟的一类增材制造技术，在打印成型过程中包括三维建模、光敏树脂制备、打印参数调控、后处理等步骤，内容涉及机械、光学、高分子化学、软件工程学等相关知识。为提升本科生的实验兴趣和实验技能，进一步培养其科研和创新意识，我们面向本科生设计了基于光固化3D打印技术的创新实验。实验采用基于光引发自由基聚合的数字光处理(DLP) 3D打印技术，通过对打印过程全流程的参与实践，达到让学生了解3D打印的原理、打印材料的合成和打印技术的过程等相关知识，从而达到可以自主操作完成光固化3D打印的实验教学目的。最后，通过对实验结果的分析，进一步培养学生分析问题和解决问题的能力。

Abstract:

As a relatively mature additive manufacturing technology, photocurable 3D printing technology includes 3D modeling, photosensitive resin preparation, printing parameters regulation, post-processing, and other steps in the printing process. The content involves related knowledge of machinery, optics, polymer chemistry, software engineering, and so on. To enhance undergraduate students' experimental interest and skills, and further cultivate their awareness of scientific research and innovation, we designed an innovative experiment based on photocurable 3D printing technology for undergraduates. The experiments are based on free radical polymerization by digital light processing (DLP) 3D printing technology, and through the printing process of the whole process involved in the practice, we hope students can understand the principle of 3D printing, the printing material of synthesis, and the process of printing technology and related knowledge. Finally, through the analysis of the experimental results, we can further develop students' ability to analyze and solve scientific problems.
