The MakerLab isn’t just on Illinois’s campus anymore! Every Monday, guru William Jones heads over to the Champaign Public Library to help with the after school program for teens. Will and a high school volunteer, Shreya, helps the kids learn basic 3D printing and TinkerCAD, a 3D design software. There is even 2 Ultimaker printers at the library for the kids to use and print their models on! The MakerLab is really excited to be able to continuing to teach kids 3D printing and TinkerCAD and encouraging them to learn more about 3D design and STEM with 3D printing! Be sure to stop by and see us at the teen lounge next time you are at the Champaign Library on a Monday!
One of many workshops offered by the Illinois MakerLab over this summer was Project City X, an international education workshop taught by Ron Duncan from University of Illinois Extension, who manages the southern Illinois operations of the Illinois Marketplace and Maker Literacy project (https://immlp.illinois.edu/). The workshop was geared toward students ages 8 to 13 and taught problem solving using the design thinking process and created solutions using 3D printing.
The workshop was based around the story of a group of travelers from Earth in the not-so-distant future who have been sent to a remote planet to build a settlement called City X. However, soon the travelers encounter challenges and social problems that affect not only themselves but everyone in City X. That’s where the students attending the workshop came in, solving the problems in groups of two or three through a five-step design process.
The first of these steps was Empathy. The students discussed how the travelers must be feeling based on their individual problems, which gave them a better understanding of the challenge at hand. The next was defining the difference between social and personal issues including which major world issue aligned with their challenge. The third was Ideation or brainstorming with only two constraints. The students’ inventions could not have been something that already exists and the ideas must have come from the students themselves.
After the students had their ideas they created prototypes using markers and paper, and then discussed them with peers and teaches in order to help them improve and revise their creations.
The final step allowed the students to use a simple 3D modeling software called Tinkercad to create 3D models of their inventions. They could then print their designs using one of the many 3D printers in the lab.
At the end of the workshop each group presented their creations to the staff and their parents, explaining the problem, a bit about their design process, and finally the solution. Upon their departure the students were rewarded with a certificate of completion from the Illinois Makerlab, in recognition of their newfound skills in designing with 3D modeling and printing.
While chaperoning the students at the lab, Kyle Potthast, the program specialist had an idea to create a souvenir to give as a gift to the top performing teams at the end of the camp. He needed this for the final presentations, about 36 hours after his visit to the lab. He discussed the idea with our New Guru, Scott, and he had custom, souvenirs printed within 24 hours. https://youtu.be/ToFToSFDryA
A selection of the hands available on e-NABLING the Future's website
This semester Nora and I worked with Enabling the Future on designing and printing 3D prosthetics. Nora found the company and Vishal helped with getting in touch with the e-NABLE team at SXSW. From there we had our first assignment. In order to be certified by e-NABLE to make prosthetic devices for real people, we had to first print and assemble a prototype hand. The designs are premade so they just need to be printed. In some cases, the hands or fingers need to be resized to fit the end user. Our first hand was called the Raptor Reloaded, printed in black and blue filament. Printing the materials was quite easy compared to assembling the hand. The instructions were available online with detailed pictures and descriptions. The assembling process taught us a lot about how best to make the hand and what were some obstacles that we faced. For example, a lot of the parts needed to be filed down so that it would fit easily together. We also worked with the tension in the fingers so the hand would move properly and learned how to tie some pretty complicated sailor knots that the site suggested we use for the hand.
After the first hand was sent in, we decided to print another Raptor Reloaded to be used as a sample in the Maker Lab for future students that are interested in the project. The process was very similar to the first one except we didn’t have all of the assembling materials needed for the hand such as the strings, screws, and Velcro. Enabling the Future sells packages that cost around $25 for materials for the Raptor Reloaded. Instead of buying another package, we improvised with some of our own materials. Feel free to check out the hand in the Maker Lab during open hours!
Towards the end of the semester, the e-NABLE team got back to us about a real recipient, his name is Bruce and he is a 53 year old male from North Carolina. He is missing three of his fingers on the right hand, so instead of making a prosthetic hand we were tasked with making replacement fingers. Some sizing needed to be done in the fingers, but other than that the prints were ready. The instructions for the Owen Replacement Finger were also available online; however, they were not as detailed as the Raptor hand. We also had to improvise on getting the necessary materials such as a glove, needle and thread, and elastic, which were not available in a pre-made kit for this type of hand.
The MakerLab will keep working with the e-Nable organization, and enable students to create an impact and learn digital fabrication at the same time.
