Promoting Advancement and Computerization of Monodzukuri Education in Junior High School with Three-dimensional Molding Device

开发了包括齿轮、连杆等的新的机械学习工具包。使用该工具包，许多种机制很容易组装在一个面板上，学生能够使一个机制，可以移动，就像它是预期的。因此，该套件提高了机构的学习效果，因为套件的每个部件都是使用3D-CAD设计的，可以使用3D打印机轻松加工。此外，这些部件可以使用树脂大量模制。因此，该套教材可以较低的成本引入学校。本文详细介绍了该工具包的零件设计和组装方法，并进行了技术课程教师监督实践课的评价。

New mechanism learning kits comprising gears, links, etc. was developed. Using the kit, many kinds of mechanisms are assembled easily on a panel and students are able to make a mechanism which can move just as it was intended. Therefore, the kit improves the learning effect for mechanism, because each parts of the kit is designed using 3D-CAD that can be machined easily using 3D-printers. Furthermore, the parts can be molded in large quantities using resin. Therefore, the kit can be introduced to schools at a lower cost. In this paper, designs of the parts and assembling methods of the kit are explained in detail, and evaluations from the technical course teachers who oversee practice classes were carried out.
