A hand manipulates a blue 3D printed rotor from ATNeal at Thingiverse. This is a simple model that can be used to have a tactile demonstration when teaching the rotor gesture for VoiceOver.

The 3 Ps of 3D: Perception, Pedagogy, and Practice for 3D Printing

3D printing is increasingly used in STEM education. How can it be made accessible to students who are blind or visually impaired?
  • Printing. How might someone find and select appropriate models for printing? What are effective workarounds for working with accessible 3D printing hardware and design software? E.g., how might I teach or learn how to use OpenScad with blind students? (Stay posted for webinars on accessible 3D printing workflows!)
  • Practice. How might teachers, blind students, or blind individuals access 3D printing? (Stay posted for information on how to access international, national, and local resources for 3D printing.) 
  • Pedagogy. How can 3D models be used to support blind students' engagement with STEM curricula? How might 3D models be used to convey concepts via the tactile rather than visual sense? (Stay posted for webinars on lesson planning with 3D models.)
