One of the most important element in tissue engineering is a scaffold which have porous structure, proper mechanical strength, biocompatibility and biodegradability. In this study, we fabricated a scaffold using a blu-ray based micro-stereo lithography(MSTL) apparatus. The material used in scaffold fabrication was PPF-DEF, which is well-known for biodegradable photopolymer. Through post-curing process, the comprehensive strength of the fabricated scaffold was enhanced. To demonstrate the biocompatibility of PPF-DEF scaffold, MC3T3-E1 pre-osteoblast cell was seeded onto PPF-DEF scaffold and cultured for 3 days. The result shows that the PPF-DEF scaffold fabricated by a blu-ray based micro-stereo lithography apparatus is applicable to bone tissue regeneration.
