The invention relates to a 4-axis 3D printing tubular medical stent and a preparation method and application thereof. The invention solves the problem that the porous tubular stent is difficult to directly construct by extrusion type, particularly Fused Deposition Modeling (FDM)3D printing, the prepared medical stent has an accurate and controllable multistage pore structure in structure, the method is simple and quick, is suitable for various materials, and has good application prospect in repairing tubular tissues and organs including blood vessels, trachea, esophagus, urethra and the like. |
