Designing a Low-Cost Open-Source 3D-Printed Hand Prosthesis for Children

Quick fact

Open-source 3D-printed hand prostheses, such as those developed by the e-NABLE community, can be made for as little as $20–$50 in materials, compared to thousands of dollars for commercial devices, and can be printed and assembled in less than 24 hours.

Why this is interesting

Imagine a child missing a hand whose family cannot afford a conventional prosthetic. What if a plastic hand, printed on a hobbyist 3D printer, could cost less than 10% of a commercial device?
