Zusammenfassung:	The invention discloses a preparation method of a 3D printing bionic porous implant based on TPMS (Tire Pressure Monitor System). The preparation method comprises the following steps: firstly, carrying out bionic porous implant modeling, applying a Gyandroid structure to the implant, and designing the bionic porous implant by adjusting parameters such as porosity and aperture and matching the strength and elastic modulus of cortical bone and cancellous bone so as to improve the stress shielding effect. The strength and elasticity modulus of cortical bones and cancellous bones are matched, the bonding strength is effectively improved, the bone bonding rate is increased, and the planting success rate is increased; the preparation of the bionic porous implant is realized by applying a 3D printing technology, the surface roughness of the implant is increased through surface treatment, the contact area of a bone and the implant is further increased, an ideal space for cell adhesion and tissue ingrowth is provided,
