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

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

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

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

Technology to Empower http://www.notimpossiblelabs.com/#!project-daniel/c1imu 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.

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

Working Smarter The NASA crank… for tables on campus!

Access to Learning

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

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?

Standards May Apply BANA Tactile Graphics Standards www.brailleauthority.org/tg

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

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. http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1358&story_id=327&images=

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

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

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

Libraries APH Tactile Graphic Image Library ZyChem http://www.aph.org/tgil/ ZyChem http://www.tactilelibrary.com

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

IVEO Images View Plus has some predrawn images available http://downloads.viewplus.com/examples/ All files https://viewplus.com/examples/bundled-iveo-examples/

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

3D Doodler Video of the 3D Doodler being used https://www.youtube.com/watch?v=emUlHFWcHck Stencil libraries and project ideas http://the3doodler.com/projects/

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

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

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

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

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

Repositories and Communities Thingiverse – huge repository – awesome! https://www.thingiverse.com/ Library Lyna – Braille optimized – growing http://www.librarylyna.com/ 3D Warehouse – used by those on sketchup (which was a google product and not great for prints, but has sold) https://3dwarehouse.sketchup.com/index.html GrabCAD – used by engineers https://grabcad.com/ Variety of models, including those created from photos http://www.123dapp.com/Gallery/content/all

Hands-On Go to Thingiverse to search for files of interest http://www.thingiverse.com/ Create TinkerCad account and complete tutorials then try opening saved files and manipulating them https://www.tinkercad.com/

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?
