After losing his right forearm in a factory accident, Chang Hsien-Liang tried several artificial limbs but he was never satisfied.
The arms he could afford were too basic and the robotic hand he wanted was too expensive.
So the 46-year-old engineer from southwest Taiwan set out to design and build his own prosthetic arm using 3D printing technology.
“After getting my own bionic arm, my daily life improved. It became easier to do things like riding a bike and eating a meal,” Chang said in an interview.
