Query: Desarrollo de experiencias para la ense\~nanza y difusion de la Optica
  con impresion 3D   In this work, we present three experiences developed with 3D printing
technology for teaching in Optics. These activities were planned, designed, and
implemented to go deeper into knowledge about light polarization, reflection
and refraction phenomena, and colour perception. The planning methodology is
also detailed, in particular, the design and description of the activity.
Experimental guides, 3D models and assembly manuals are available in a free and
freely accessible web space. In summary, we demonstrate that the 3D printing
can be used as a technological, inclusive and pedagogical resource for
teaching. This methodology can be extended and adapted to other disciplines, as
well as applied locally in educational institutions.
