Abstract
A kind of drug releasing 3D porous material was designed and fabricated, which could used for bone repairing. The β-tricalcium phosphate (β-TCP) material were fabricated through the rapid prototyping (RP) combining with the freeze-drying, where the scaffold-mould was fabricated by RP. The material was fabricated with ball-milled slurry which solid content was 40%, the pre-freezing temperature was-10°C, and then the material was freeze-dried under vacuum environment at-30°C without sintering. The test results showed that the material had good structure pores with the mean size of 150μm through controlling the pre-freezing temperature, and the compressive strength of the samples was 0.216Mpa.
