▎ 摘　　要

NOVELTY - Bone-induced calcium phosphate ceramic based on 3D printing comprises multiple pore structure units, where the pores structure units are the most densely packed lattice structures, the pores are composed of macro pores and through holes opened on the pore walls of the macro pores, and each macro pore occupies the positions of the atoms in the lattice structure. USE - Bone-induced calcium phosphate ceramic based on 3D printing. ADVANTAGE - The bone-induced calcium phosphate ceramic has better bone inductivity and bone repairing effect, and has scientific design and simple method, and effectively improves osteoinductive performance of the ceramic under the premise of not changing the ceramic chemical composition with the same chemical component, the same porosity, but different pore structure of ceramic, and better bone inducing effect, the ceramic has good penetrating property, which is good for transmission of nutrient substance, improving bone repairing performance, and promoting the application in the clinical has very important meaning. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing bone-induced calcium phosphate ceramic based on 3D printing which involves: i. constructing calcium phosphate ceramic hole structure unit in the modeling software, unit body is imitated hexagonal closest stacking lattice structure, each macro-hole occupies each atom position in the lattice structure, then calculating the space arrangement mode of the unit body to obtain the calcium phosphate ceramic model data and introducing the model data into the 3 D printer; ii. configuring calcium phosphate ceramic for 3 D printing needed slurry, introducing the slurry into the material box of the 3 D printer, printing the ceramic blank according to the model data introduced; and iii. degreasing and sintering the prepared ceramic blank to obtain the bone-induced calcium phosphate ceramic.
