Arm Yourself!

Arm yourself is an application that creates parametrically generated prosthetic arms that can be 3D printed to meet an international need.

This is an ongoing project that will shorten time delivery time, lower costs, ensure safety and e-nable people worldwide with limited access to useful, repairable and well fitting prosthetic arms and hands. There is a three way chasm that creates friction to medically under served children both locally and internationally. This gap exists between what is medically available, what is affordable and what is maintainable. Arm Yourself is a bridge over these troughs of disillusionment. It will provide unique components to meet the needs of a widely variable audience of arms.

We kicked off this project last summer with This summer we will be pushing it further. The next steps are to complete a calibrated cuff and hinge to match the socket. We will tie into the Fusion 360 API's to clean and prepare the files for 3D printing. Lastly, we will scale the current iteration of Skip Meese's Gripper Hand and build the U/I to tie them all together.


This is the image to get the cut effect going!

I'm sure it is the case for most 3D printer owners that their printers are idle the vast majority of the time. How can this printer time be used for projects like this? Are there generic parts that could be printed and supplied? Are they typically PLA or ABS?

Absolutely. I work with a group called e-nable that serves as a matchmaker between makers and recipients. I would recommend checking it out. 

ABS is preferred for hot climates as PLA tends to creep at higher temperatures. FOr that reason, PLA is advantageous for thermoforming
