The main goal was the digital transformation, increasing the capacity and readiness of institutions to introduce 3D printing programs into the regular teaching process. Students and teachers from Technical secondary schools shared and improved their knowledge about 3D modeling and 3D printing and gained new knowledge about how a 3D printer can be used both in schools and in real conditions. During the implementation of this project, both students and teachers gained new professional and business experiences during visits to several companies that deal with 3D printing. We also managed to raise students' desire for teamwork through workshops and motivation for learning, especially for learning English because the complete mobilities were conducted in English. We also wanted to raise the level of tolerance towards different cultures among all project participants during working visits to schools, which we succeeded in by forming mixed teams at workshops and during free activities and socializing. By including 50-60% of students with positive inclusion based on an unfavorable socio-economic position, we wanted to give an inclusive note. We also wanted institutions to introduce the 3D printing program into regular curriculum.
There was a lot of interest in 3D printing among students each year and no subject in the curricula that dealt with this topic. In 2020 students were given the opportunity to choose the optional subject Additive technologies, which unfortunately was purely theoretical. An even bigger problem was that official literature did not exist for this subject and, in general, for this topic. In 2023, this optional subject was no longer offered to students. To meet the needs of the students, the school bought a 3D printer and formed extracurricular classes. Also, the classroom with the 3D printer was occupied and these classes were held after regular classes when the classroom was free. Students could not catch up with these extracurricular activities, in addition to the demanding timetable. For all interested students from remote areas or villages it was almost impossible to attend extracurricular classes to enrich their knowledge and skills with this technology. That's when we came up with the idea to introduce 3D printing into regular classes and write a practical "user-friendly" handbook, which will be able to be used by our students in regular classes, as well as by all the others who are interested in modern technology.
