A group of ASU materials science engineers, Jason Enriquez, Tayler Fulton, Nicholas Lauer and Brian Zucker, dedicated its Capstone project to improving existing 3D printing open source designs. By connecting through their professors with local companies in the additive manufacturing field, the students are identifying better materials and how to 3D print with them for this purpose. The end goal is to improve on current open-source transhumeral (upper arm) prostheses; additional guidance is being offered by Justin Ryan, the lead research scientist at the Cardiac 3D Print Lab, Phoenix Children’s Hospital.
