Bioceramics scaffolds for bone tissue regeneration are fabricated by polymer sponge method, freeze drying, and melt molding process in general. However, these typical processes have some shortcomings in both the structure and interconnectivity of pores and in controlling the mechanical stability. To overcome this limitation, the rapid prototyping (RP) technique, which can generate a pore structure and scaffold morphology directly from computer-aided design data, have proposed. Conventional RP process in fabricating bioceramics scaffolds all used ceramic powders and organic binders to form the green bodies prior to sintering at high temperature. However, sintering process at high temperature leads to bad cost performance, unexpected crystallization, unstable mechanical property, and low biofunctional performance. The purpose of this study is the development of room temperature fabrication process for building 3D porous bioceramic scaffold. |
