Abstract
ABSTRACT Objective: To construct a porous titanium-based implant with good biocompatibility and appropriate modulus matching human bone. Methods: Porous titanium with triangular, quadrangular and hexagonal prism as structure monomer were constructed by 3D printing, and the effects of pore structures on the mechanical and biological properties of materials were investigated by computational simulation, mechanical property tests and cell adhesion and proliferation tests. Results: The modulus of titanium with quadrangular monomer was the closest to that of human bone. Besides, the quadrangular sample also shows the best cytocompatibility, presenting the most promotion effects on cell proliferation. Conclusion: The porous titanium constructed by quadrangular monomer has the best comprehensive performance, and the relevant results can provide data support for the design and clinical application of 3D printing porous titanium-based implants.
