There is an "oxygen inhibition layer" forming when light-curing 3D printing with radicals resin material, leading to continuous printing and surface quality improvement. Since the mechanism of controlling the structural precision of printing parts is unclear, it is thus difficult to control the precision of printing porous parts with complex shape. This paper used a self-made free radical bioceramic slurry to produce porous bioceramic scaffolds through stereolithography, investigated the three-stage curing interval in the lithography process and the principle of controlling the molding accuracy of the oxygen barrier layer. and proposed a reasonable control oxygen-inhibition layer method for adjusting the printing process parameters. It is indicated that the oxygen-inhibition layer can improve the molding accuracy of ceramic parts, and affect its mechanical properties. According to the established mechanism of the thickness of the oxygen-inhibition layer on the forming accuracy and mechanical properties of the porous structure of the bio-bone ceramic scaffold, the high-precision manufacturing basic theory and method for the multifunctional ceramic printing technique and the application of ceramic base bone substitutes were proposed.
