ESTEM-3D is an Erasmus+ funded project, whose goal is to assist disadvantaged areas, including schools, educators, and students, in learning about 3D printing technologies. While 3D printing is still a developing technology, it has already begun to excite students when present. The ESTEM-3D project trains educators to expand 3D printing in secondary schools, fostering access to new technologies. It promotes digital transformation, new curricula, and supports disadvantaged areas, all to equip students with skills for a changing tech-driven world, enhancing critical thinking, problem-solving, and collaboration.
