Low cost orthotic design and fabrication for children at NYU Langone Medical, in collaboration with CHIDS, the NYU Ability Project, and the NYU MakerSpace
We began this project by printing and testing a number of prosthetics and orthotics currently available, including E-nable and the Airy exoskeleton.
Due to patients' needs, we focused on the elbow driven model. The Airy exoskeleton uses a combination of 3D printing and traditional splint making techniques to achieve it's form. We received splinting lessons to better understand the process of forming material directly on a patient.
Experiments with Splinting Technique
Experiments with 3D Scanning
At this time we also began experimenting with 3D scanning as an alternative to thermoforming.
We found traditional hinges didn't allow for enough range of motion. We experimented with a number of different forms and materials and eventually arrived at a vinyl hose, reinforced with bungee.
The most difficult element of this orthotic is the finger piece, as it must be small, accurate, flexible, and strong.
We began working with a plate that fit on top of the fingers and caps that connected the finger tips to the cables. We are currently testing a single, four-fingered ring that will pull all for fingers up at once.
