摘要
目前3D打印教学实验的内容大都是利用商业化聚合物让学生初步了解3D打印的基本流程.这种基础实验难以让学生接触到前沿的新型材料,对于新材料如何与3D打印技术结合这些底层科学问题也往往被忽略.高分子凝胶具有富溶剂特性和良好的生物相容性,在组织工程、药物输送、柔性电子等诸多领域都有着广泛的应用前景.本实验结合了作者近期的科研成果,在给学生指定新型凝胶基材料之后(水凝胶/有机凝胶),引导学生探索调控凝胶基材料的流变学性能和溶胀性能,并将凝胶基材料和3D打印技术有效地结合起来,从而对这种先进材料的加工方式有更加具体的了解.本实验的教学设计,强化了学生对诺贝尔奖成果的深入理解,并增强了学生运用所学专业知识服务国家发展需求的意识,培养了学生勇于探索的创新精神和分工合作的团队意识.
Abstract
Currently,the content of 3D printing teaching experiments mostly focuses on introducing students to the basic workflow of 3D printing using commercially available polymers. However,these basic experiments often fail to expose students to cutting-edge new materials and overlook the underlying scientific questions of how these new materials can be combined with 3D printing technology. High-strength hydrogels,with their solvent-rich properties and excellent biocompatibility,have extensive prospects in various fields such as tissue engineering,drug delivery,and flexible electronics. This experiment integrates the author's recent scientific research achievements and instructs students to explore the rheological properties and swelling behavior of designated novel gel-based materials (hydrogels/organogels),effectively combining these gel-based materials with 3D printing technology,thereby gaining a more specific understanding of the processing methods of these advanced materials. The instructional design of this experiment enhances students' in-depth understanding of Nobel Prize achievements,strengthens their awareness of applying their professional knowledge to serve national development needs,and cultivates their innovative spirit and teamwork consciousness in the face of exploration.
