基于3D打印技术的水产学科教学实践与探索

Practice and Exploration of Aquatic Science Teaching Based on 3D Printing Technology

摘要: 3D打印技术在近年来飞速发展，被广泛应用于各行各业，在教学中也受到越来越多的重视。本研究设计问卷，调查桌面级3D打印技术在水产学科教学中的应用现状和需求，根据调查结果设计3D数字模型，利用FDM (fused deposition modeling)熔融沉积成型和LCD (liquid crystal display)光固化两种桌面级3D打印技术，打印包括头足纲、腹足纲、海星纲、甲壳纲以及微藻等典型水生生物模型，对比分析两种3D打印技术的优缺点以及打印不同模型的适用性。结果表明，上述模型均能够通过3D打印技术实现并进行教学上的应用，FDM和LCD适合打印的模型有所不同。最后提出了3D打印技术在水产学科教学中应用的问题和展望。

Abstract: 3D printing technology is developing rapidly in recent years, it is widely used in all walks of life and receives more and more attention in teaching. In this study, we design a questionnaire to investigate the application status and demands of 3D printing in aquatic science teaching, and design 3D digital models according to the survey results. We use FDM (fused deposition modeling) and LCD (liquid crystal display) photocuring two desktop level 3D printing technologies to print typical aquatic science biological models including Cephalopoda, Gastropoda, Asteroidea, Crustacea and Microalgae. We also compare and analyze advantages and disadvantages of these two 3D printing technologies and the applicability of printing different models. The results show that the above models can be realized through 3D printing technology and applied in teaching, and the suitability of FDM and LCD is different. The problems and prospects of the application of 3D printing technology in aquatic teaching are put forward.
