3D printing personalized artificial intramedullary stent

The invention relates to the field of biological medicine, in particular to a 3D printing personalized artificial intramedullary stent which is prepared by taking Zn < 2 + > modified calcium silicate/beta-tricalcium phosphate as a main material through a 3D printing technology. The strength of the stent is greatly increased, normal bone strength can be simulated, and intraoperative reduction is facilitated; meanwhile, due to addition of Zn < 2 + >, trace metal ions necessary for a human body are introduced into the material, and the strength and the biological performance of the material are further improved. The 3D printing technology is adopted, the individualized artificial intramedullary stent can be more accurately manufactured, the individualized printing customization service requirements of clinical similar patients are met, the uniform porosity in the artificial bone is guaranteed, the size and number of gaps in the stent are accurately controlled, and new bone ingrowth and creeping replacement are f
