The invention discloses a method for forming a porous bone hydroxyapatite ceramic cell scaffold based on a photocuring 3D printing technology. The method mainly includes five steps: ball-milling bone hydroxyapatite powder, mixing pore-forming agent, configuring light-curing resin slurry, light-curing and forming a ceramic blank, and degreasing and sintering the blank. The process steps of the present invention are relatively simple, and can form complex scaffold structures and hollow topological structures that cannot be formed by traditional methods, especially porous structures containing two pore sizes, and can produce cell scaffolds similar in structure and composition to human bones. |
