Developing a 3D Printer for Functionally Gradient Soft Materials

Abstract

Gradient soft materials have exciting potential in biomedical applications; however, challenges still exist in terms of their fabrication and validation. This project aims to design a 3D printer capable of reliably producing samples of silicone rubber with gradient material properties. The design will focus on the pumping and extrusion subsystems, with the addition of controls adaptation. These samples will be used to develop standards and protocols for material characterization to be used in future applications. The initial design shows potential, but design iterations are required for performance optimization.
