Abstract

In this paper, the manufacture method of degradable intervertebral fusion stent with good mechanical properties and biocompatibility based on 3D printing technology is researched. Firstly, the mixing process of synthetic macromolecule and bioceramic powder is studied. And develop a high temperature stirring grinding device and realize arbitrary proportion of composite materials. Secondly, the intervertebral fusion model is processed and the print path is optimized based on discrete allocation algorithm of modeling section of cylindrical structure and print trajectory optimization algorithm. Then, the influence of printing temperature and printing layer on the bonding strength of the stent is studied, which provides a theoretical basis for the reasonable parameters setting. In addition, the composite for stent is studied, with different materials in different ratios are mixed and compressive strength and compressive modulus of each stent are tested. The ratio of composite with good mechanical strength is obtained. Finally, the intervertebral cage stent is constructed with good mechanical properties and biocompatibility.
