GARCIA ELIZONDO, Alberto et al. 3D Creator Laboratory: A proposal to teach, learn and enjoy chemical sciences with threedimensional printing. Educ. quím [online]. 2023, vol.34, n.4, pp.50-63.  Epub 22-Ene-2024. ISSN 0187-893X.  https://doi.org/10.22201/fq.18708404e.2023.4.83705.

This article documents the installation, start-up and pilot testing of a 3D printing laboratory to develop competencies in Science, Technology, Engineering and Mathematics (STEM) and strengthen “selfefficacy” in students of careers in chemical sciences. “Self-efficacy” describes a person’s belief in their ability to succeed in a particular situation, including learning. A makers laboratory 3D is a digital fabrication space for three-dimensions printed prototypes that can materialize intangible chemical concepts. Consequently, it is a space that helps students to build meaningful experiences through sensoryenriched lessons by designing, creating, viewing and manipulating prints within a teacher-directed learning environment. The impact of the Makers 3D Lab´s experience was measured qualitatively through an internationally validated questionnaire on confidence in STEM skills. The test was performed before and after an experiential 3D printing experience in thirdsemester students of an academic laboratory and in seventh semester students of a theoretical course. Results showed an improvement in the self-efficacy of STEM competencies of 60±5% and 10±6% for the academic laboratory and the theoretical subject, respectively. In conclusion, the processes of teaching and learning chemistry in a Makers 3D Lab observed a meaningful experience that allowed to enjoy and strengthen the confidence in self-management of knowledge for the students.
