Many para-athletes and people in the world can't have a prosthesis because it's too expensive. I want to create a cheap prosthesis for them. A simple prosthesis can cost minimum 6 000 euros (~7 000$, 46 379 CNY). I'm in contact with a mentor who made his own prosthetic arm. I found on his website (http://myhumankit.org/tutoriels/print-my-leg/) some tutorials about how to print a leg with 3D printer and laser cutter. I would like to improve this with new material or electronics.
If you have any idea or tools, i'm open to your suggestions!! You can help too if you want!!
