Examination of Scale of Modeled Objects for the 3D Printers in School Education

Abstract

The use of 3D printers has been spreading in schools as well, and 3D printers were newly introduced in the revised Junior High School Course of Study Guidelines for Technology and Home Economics and the Guidelines for the Development of Teaching Materials. However, when using a 3D printer in class at school, there is a problem that it takes time to model the creation of all students. In this letter, Measure the modeling dimensions and the roundness of the corners when the scale of the model is changed, and consider the possibility of using it at school based on the obtained data.
