Embodiment 1
[0028] (1) Preparation of ceramic slurry: Add 70 parts of calcium silicate powder to 30 parts of photosensitive resin premix, stir under normal pressure, so that each component is dispersed evenly, and ceramic slurry is obtained;
[0029] (2) Printing and forming: the slurry is poured into the barrel of the stereolithography printer, the STL format model is imported into the stereolithography printer, and the printing parameters of the stereolithography are adjusted so that the ceramic slurry is stacked and formed layer by layer. Solidifying the slurry to obtain a ceramic stent green body;
[0030] (3) Place the ceramic support green body in a muffle furnace for degreasing and sintering. The degreasing sintering system is set as follows: 30-300°C heating rate is 5°C / min, heat preservation for 2 hours, 300-600°C heating rate is 5°C / min , heat preservation for 2 hours, 600-1100 ° C heating rate of 3 ° C / min, heat preservation for 2 hours, 1100 ° C ~ room temperature natural co...
