Mexican students make recycled filament that lets printed prosthetic hands operate touchscreens
Students at the University of Guadalajara have developed a 3D printing filament from recycled plastic and nanomaterials that lets printed prosthetic hands work on phone and tablet touchscreens. The project, called Filna, won the Next Gen category at the Enactus Mexico 2026 national competition. The team aims to lower the cost of hand prostheses through the material itself.
