Recently, a variety of methods for fabricating bio-ceramic scaffolds which help bone regeneration have been developed. However, the conventional methods have difficulty in exquisite control of pore structures such as porosity or pore size, which strongly affects on mechanical and biological properties. To overcome these problems, the studies about Additive Manufacturing(A.M.), which is one of the most promising techniques, are performed vigorously. Fundamentally, this technique produces sample with CAD files. On this account, complex shapes are able to be realized with high resolution. This study proposes a new way of producing porous bio-ceramic scaffold using D.L.P.(Digital Light Processing) technique which is one of the Additive Manufacturing with ceramic compound(45vol%) having high ceramic contents which are mixed BCP(Biphasic calcium phosphate) and HDDA(1,6-Hexanediol diacrylate) for reinforcing mechanical properties. In this study, we evaluated the effect of sintering temperature(1200, 1250, 1300, 1350℃) on the crystalline phase structure of BCP scaffold and mechanical properties and the in vitro apatite forming ability in SBF. |
