In the field of robotics education, understanding the design, manufacturing, and control of robots is an important aspect of understanding the development of robots. Therefore, various university-level robotics education courses have been created to cover these topics. However, students typically learn about design, manufacturing, and control in different classes. This can potentially lower their understanding of robotics development. There are various reasons why these topics are taught in different classes, but the main reason is the difficulty of manufacturing. Manufacturing education parts often requires a machine such as a CNC, and in the case of a class for many students, it takes a lot of time to manufacture objects designed by students. Recently, low-cost 3D printers have become available, which are considered a solution for reducing manufacturing time. In this paper, I propose a year-round robotics class that covers design, manufacturing, and control. Then I introduce the developed 5-axis robotic arm for education, which can be manufactured using 3D a printer, as a result of the proposed class. The evaluation of the developed arm showed that the maximum payload (with a safety factor of 2.5) was 2.2 [kg], and the maximum repeatability was ± 0.201 [mm].
