Preparation method of light-cured 3D printing Thiessen polygon bionic structure tricalcium phosphate/silicon dioxide composite biological ceramic
The invention discloses a preparation method of a light-cured 3D printing Thiessen polygon bionic structure tricalcium phosphate/silicon dioxide composite biological ceramic, and belongs to the fieldof 3D printing ceramic and bionic structure design. The composition provided by the invention is prepared from tricalcium phosphate powder with an average particle size of 30-50microm, silicon dioxidepowder with a particle size of less than or equal to 100nm, 405nm waveband photosensitive resin, a cross-linking agent 3, 3-dimethylacrylic acid resin and a diluent polypropylene glycol according toa certain ratio. Through the printing forming and degreasing sintering process, the tricalcium phosphate/silicon dioxide bionic porous biological ceramic bone tissue engineering scaffold with compactgrain combination, porosity adjustable between 50% and 80% and compression resistance between 3MPa and 8MPa can be obtained, meets the compressive property requirement of human body cancellous bone and has the structural characteristic of bionic human body cancellous bone.
