In this study, PEO (polyethylene oxide), which is water-soluble polymer, was added to overcome the problem that NaCl particles were not leaching out at PCL (polycaprolactone)/NaCl scaffold if dispensing-type SFF (solid freeform fabrication) apparatus was utilized to fabricate. Before fabrication of dual-pore scaffold, PEO, PCL and NaCl powders with certain size were prepared. Afterward, PEO, PCL and NaCl powders were mixed via stirrer for 24hours. After that, mixed powders were filled in the barrel of bio-plotter. Subsequently, mixed PEO, PCL and NaCl powders were plotted under consistent pressure and melting temperature. Built scaffold was soaked into the D.I. water to leach out PEO and NaCl particles for 24hours in the sonicator and dried in the desiccator. The porosity of fabricated scaffolds was measured. Moreover, morphology of fabricated scaffold was observed through FE-SEM.
