The idea of this project is to involve CFIE in Zamora with other Public Teacher Training centres abroad, along with Primary and Secondary Schools, to use 3D printers in a collaborative project in educational environments to generate and share the educative materials to be tested at schools. This project aims to motivate teachers to design 3D educative materials to perform manipulative activities to apply the curriculum of different subjects and levels. It would be great to involve students as well to get to know how to design and print with the 3D printers. It is necessary to have a 3D printer, and at least, one of the members in each school who participates in this project, needs to be an expert in order to teach his/her colleagues. The main objective is for experts to train teachers, so that teachers can train their students, in order to know how to use the 3D printer and to test the materials created with the collaborative work ot teachers and students.
