The invention discloses a multi-structure reinforced personalized calcium phosphate ceramic structure, a preparation method and application. The multi-structure reinforced personalized calcium phosphate ceramic structure comprises a porous structure and a mechanical reinforcing structure for supporting and dispersing force, the porous structure comprises spherical holes which are randomly distributed and through holes which are formed by intersecting with the spherical holes; the mechanical strengthening structure comprises string beams arranged on the upper and lower surfaces of the ceramic structure in an array mode and web beams arranged on the side face of the ceramic structure and used for being connected with the string beams. Inclined web girders are further arranged between the string beams and the web girders; the biological performance and the mechanical strength are enhanced through the porous structure and the mechanical strengthening structure, the ceramic fracture risk is reduced, the porous str
