摘要：

The electrohydrodynamic jetting (or E-jetting) 3D printing system developed in-house is used as a fiber-based fabrication approach which applies electrical voltage between a nozzle and a substrate to deposit fibers onto the substrate layer by layer. PCL (polycaprolactone) is chosen as biomaterial of scaffolds because of its bio-compatibility and bio-degradability. This study focused on the fiber characteristics impacted by two main parameters, solution dispensing feed rate and plotting speed, to optimize filament diameter, filament formation and stability. Scaffolds fabricated with 70wt% PCL with size of 30x30mm and pore size of 300x300 mu m were investigated and characterized.
