The Initial Development and Practice of Training Materials Using 3D Printer to Employment Support for Inclusive Society

In Japan, in the field of employment of person of with disabilities, the number of employments is increasing but still there is a problem that there are only a few employment types and industries. [1] In real time, COVID-19 infection control measures in addition to the use of ICT have accelerated new work styles. Also, 3D printers are creating new designs and manufacturing styles. [2], [3] Based on these, the purpose of this research is to develop the training materials so that person with disabilities can become operator of 3D printer and get the work. Finally, the use of it might make inclusive society. The research method is to develop training material and then conduct experiments to use it to verify the training effect. The training material is a video format consisting of slides and audio that can replay and stop by learners. Also, the training content is a basic knowledge of 3D printers and actual modeling operations. In the experiments, learners use the material and make a model and then they answered the questionnaire survey. As a result, by the cross tabulation of the frequency of reviewing the manual and the feeling about the speed of the manual was demonstrated that the speed of manual, contents and understanding of explanation are appropriate without the extreme repetition. In conclusion, it was found that manuals with video and audio were easier to understand in those icons could be shown when necessary. However, there are problems that it would not be possible to respond flexibly in the case of an operation error and in the case of lengthy process.
