1. Tactile Graphics Go 3D Accessing Higher Ground 2015
Tuesday, November 17, :30 p.m. – 4:30 p.m.
Westminster, CO
Gaeir Dietrich, CCCs HTCTU
Lisa Wadors, Benetech

2. Agenda Introductions 3 Different Reasons to Love 3D Printing
Context — Tactile Learning as Part of the Big Picture
3D Printing Tools and Resources
Library Exploration
Discussion

3. Introductions Please turn to your neighbors and share: Your name
Your institution
If you have any prior exposure to 3D printing

4. 3 Reasons to Love 3D Printing
Technology to Empower – Maker Spaces and people creating their own solutions – DIY AT
Working Smarter – Using technology to save money on replacement parts – NASA Crank
Increasing Access to Learning – Ted Talk Clip

5. Technology to Empower
Project Daniel brought 3D printers to the Sudan to print limbs for those impacted by war. Project Eyewriter is another impressive story of low-cost tech hacks empowering individuals.

6. DIY AT PCC is working on developing a culture of DIY AT
From standing height desks to a student printing his own hand, community members are invited in

7. Working Smarter
The NASA crank… for tables on campus!

8. Access to Learning

9. 3D Forum Funded by the Institute of Museum and Library Services
3D Printing for Education
45+ experts gathered in San Jose, CA
2-day-intensive forum
Design Day
Outcomes
Quick Start Guide
Standards Working Group
Collection of stl. files
Identify pilot opportunities

10. The Big Picture Tactile Learning Objects are one option
Not always the best option
Who is the student?
Does the student:
Have prior exposure to these concepts?
Know braille?
Have experience with tactile graphics?

11. Standards May Apply BANA Tactile Graphics Standards

12. Low-Tech Options Collage Foam sheets Magnetic paper
Raised-line drawing kit
Wiki-Stix

13. SwellTouch Graphics
Special capsule paper, “swell paper,” is “toasted” and raises wherever carbon has been laid down on the page PIAF ZyChem
A student using the smartpen with a Sewell Raised Line Drawing Kit that allows the visually impaired to feel the shapes that they have drawn.

14. Techniques
Create graphic on computer > laser print on regular paper > transfer image to capsule paper using a copy machine
Hand draw
China markers (grease pencils)
Some gel pens
Soft lead pencils (the kinds artists use)
Black erasable “white board” markers

15. Helpful Tool SnagIt From TechSmith
Allows you to “grab” all or portions of any image you can see on the computer
Images can be edited to create tactile graphics

16. Important
U.S. distributor of capsule paper: American Thermoform Corporation
Be aware: All capsule paper is not created equal!!!

17. Libraries APH Tactile Graphic Image Library ZyChem
ZyChem

18. IVEO Graphics on Touchpads
Images can be printed with an embosser or on swell paper
Touchpad allows what is tapped to be spoken and for additional detail to be articulated as needed

19. IVEO Images View Plus has some predrawn images available
All files

20. 3D Pens
Can be tricky to use; have to draw on the page and “in the air”

21. 3D Doodler Video of the 3D Doodler being used
Stencil libraries and project ideas

22. Hands-On Exploration of Options
We have stations set up around the room and there is time to explore each
Try out tools and outputs from different options for creating tactile learning objects
IVEO – Viewer (free software) with Touchpad
PIAF – Swell paper with heat unit to activate
Raised Line Drawing Kit
3D pens – single filament is fed into pen and heated at tip to allow for extrusion on the fly

23. Hands-On Exploration
Explore and have fun!
Break at ….

24. 3D Modeling/Printing Software
There are open source options (ex. Blender, Cura) Proprietary Applications AutoDesk has free apps
123D Catch
Generate 3D models from photos
123D Circuits
Design your next electronic project
123D Design
Easy 3D modeling for Web, Mac, and PC
123D Make
Unique 3D models from 2D slices
123D Sculpt+
Create 3D sculptures on iPad
Meshmixer
The ultimate tool for 3D mashups
Tinkercad
Get started with 3D modeling
Tinkerplay New!
Design, customize and 3D print for play

25. 3D Printing Filament Types
PLA – used in MakerBots and many others
ABS –harder cast – prefers heated bed
HIPS – hard cast no warping, can support (soluble)
Nylon –stronger cast – needs higher temp extruder
Flexible – needs extruder adaptor
Conductive – printer needs cleaning filament after
Specialty –wood, stone, metal, etc. – higher cost

26. 3D Printers There is a wide range of options
See handout for key characteristics
Introduction to the printers in the room

27. Repositories and Communities
Thingiverse – huge repository – awesome!
Library Lyna – Braille optimized – growing
3D Warehouse – used by those on sketchup (which was a google product and not great for prints, but has sold)
GrabCAD – used by engineers
Variety of models, including those created from photos

28. Hands-On Go to Thingiverse to search for files of interest
Create TinkerCad account and complete tutorials then try opening saved files and manipulating them

29. Closing Discussion
What are your thoughts on the usefulness of 3D printing technologies?
Which technologies/techniques might work for you?
What do you have questions about?
What do you want to know more about?
