Investigating the Impact of a 3D Modeling and Printing Workshop Designed for Blind and Low-Vision Students
A four-day community workshop that combined tactile exploration, engineering mentorship, accessible instruction, and personally meaningful 3D-modeling projects.
Visual-first tools can make engineering education inaccessible.
Students who are blind or low vision often encounter limited access to spatial concepts, modeling software, role models, and individualized technical support. The workshop tested tactile and community-supported ways to introduce design and fabrication.
My roleContributed as second author and co-researcher to workshop planning and facilitation, field documentation, collaborative analysis, interpretation, and writing within a multidisciplinary team.
Study focus
Evaluating both the learning experience and the program design.
How did tactile activities, accessible instruction, and mentorship shape engagement and confidence?
What should educators change when designing future 3D-modeling programs with blind and low-vision students?
Workshop journey
From tactile exploration to personalized models
Observation, photographs, recordings, and staff reflections were considered together to connect student experiences with specific curriculum and facilitation decisions.
Day 1 · ExploreAssistive devices, the engineering process, and introductory CAD.Computer-based 3D modeling with mentor support
Day 2 · ConnectA blind engineering mentor, tactile printer interaction, and tactile art.Tactile LEGO art activity
Days 3–4 · CreateIterative cane and luggage identifiers designed at individual paces.Personalized tactile identifier attached to a white cane
Key insights
01
Hands-on activities sustained engagement.
Tactile models and direct printer interaction made abstract concepts more concrete and supported growing confidence.
02
Representation and mentorship mattered.
Meeting a blind engineering professional helped students envision technical careers and discuss accessibility openly.
03
Accessible teaching requires flexibility.
Different technical experience and learning pace called for mentor preparation, differentiated instruction, and meaningful project choices.
Outcome
Actionable lessons for future curricula.
The workshop surfaced design priorities for community organizations and educators developing inclusive digital-fabrication programs.
Teach tactile-firstGround abstract spatial ideas in objects students can inspect and manipulate.
Prepare mentorsGive facilitators accessibility guidance while welcoming disabled technical role models.
Design for variationAllow flexible pacing, accessible transitions, and personally meaningful project choices.
