3D Printing News – 3D Prints for Teachers of the Visually Impaired

The above image shows solids that all have the same volume, you can check this by filling one with water and then pouring that water into the next, fixed-volume objects. You can use the OpenSCAD script that Rich Cameron (aka Whosawhatsis) shared or download the sample objects. But why? Rich Cameron and Joan Horvarth, well-known authors, are on a mission to get all the 3d printers in the world, in all those new classrooms to help visually impaired students make use of 3D prints to learn just about any subject, but they need help making good models. This is where you come in.

Start off by downloading the sample objects above or generating your own via the openSCAD script we mentioned. Then visit the project page on Hackaday.io to get instructions on how you can volunteer to help this community and join their Google Group to continue the conversation. This is a great tactile to learn and a great way to share your talents with the world.

“Often students with visual impairments have difficulty with concepts based on visual/spatial relationships, particularly in math and science. 3D prints offer an unprecedented asset for their teachers, and 3D printers are becoming affordable. But these teachers need help designing models. [Whosawhastis] and I have been volunteer mentors to various groups working on figuring out the best ways to use 3D printing for the visually impaired. Our goal with this project is to document some simple, practical conventions for designing models, and lay the groundwork so that interested parties can create the needed designs. We know that schools have 3D printers and want to teach design thinking to their students. This project creates a minimalist open-source way to link teachers who need design files and (sighted) students who want projects to do. We want students to create the designs for the needed models, learning science, math and other subjects while helping their visually-impaired peers.”
