The study on aerodynamically assisted Tip - Pen Direct Writing
Scaffolds require individual external shape and well defined internal structure, which is of great importance for tissue engineering. Rapid prototyping (RP) uses layer-manufacturing strategies to create physical objects and has the advantage on scaffold fabrication. A new RP technology called aerodynamically assisted Tip-Pen Direct Writing was developed to construct the complex architectures.Compared with the traditional nozzle, there is a micro-tip in the center of the micro-hole. The flow is determined by the gap between the micro-hole and micro-tip, which makes it practical for more accurate flow control. It employs a highly accurate three-dimensional micro-positioning system with the new nozzle to deposit maltose structures. 3D architectures had been made by this method, the width of fiber in which is about 120μm.
