Abstract:

The process parameters and raw materials of current commercial rapid prototyping (RP) machines are limited, thus the bone model is not easily to fabricate. In order to overcome these disadvantages, a self-developed rapid prototyping machine was used to produce bone model. In this work, the hydroxyapatite (HA), silica sol and suspending agent were mixed as raw materials. By adjusting the suitable process parameter, the bio-ceramic green parts could be formed, and then the specimen green parts were sintered at 1200℃, 1300℃, 1400℃, respectively. The shrinkage, surface roughness and compression strength were tested. Furthermore, the cell activities of the bone model were investigated through the osteoblast MG63 cells culture. The results showed that the green part sintered at 1200℃ exhibits optimum properties with greatly improved compression strength and surface roughness of Ra (12.04 μm), which is suitable for the growth of the osteoblast MG63.
