droxyapatite microstructures produced by microstereolithography using an optical fiber

Abstract

In this study, we have developed a fabrication process to produce 3D porous microparts made of hydroxyapatite (HAp), which are synthesized using a simulated body fluid, by microstereolithography using an optical fiber. In experiments, we evaluated the fabrication resolution of HAp slurry by using an optical fiber of core diameter 25 μm. A simple 3D porous structure was fabricated successfully. We also evaluated crystallites of powder of degreased body of HAp slurry, powder heated under the degreasing condition and HAp powder. In the near future, we will optimize the fabrication conditions of HAp 3D porous structures and conduct cell culture experiments. The HAp 3D porous structure will be useful for hematopoietic stem cells culture scaffolds.
