Enhancing surface charge dissipation of Melt-electrospun 3D printed scaffolds for the fabrication of tall and well-ordered architectures

摘要

This two-part project undertaken at QUT and the University of Wurzburg focused on a 3D printing technology known as Melt-electrospinning. In the first part, a melt electrospinner device was designed and assembled to fabricate tissue engineering scaffolds. An air ioniser was then then used to investigate the effects of reduced surface charge on the scaffolds such as to improve the output and height of the printed structure. The goal of the second project was to fabricate scaffolds using an electro-active polymer capable of altering its shape when placed within an electric field.
