[0022] In this embodiment, the preparation method of bioceramic microsphere artificial bone scaffold with controllable porosity specifically includes the following steps: a preparation method of bioceramic microsphere artificial bone scaffold with controllable porosity specifically includes the following steps:
[0023] Step 1. Use PFC3D particle flow software for modeling and simulation. Take the diameter D of the large ball as 0.6mm and the diameter d of the small ball as 0.3mm. When the porosity of the artificial bone is 0.59, the ratio N of the number of large and small balls is 1 : 6.
[0024] Step 2, the computer processes the three-dimensional CAD model of the artificial bone scaffold, and sequentially divides it into five two-dimensional cross-sectional graphics with a spacing of 0.6mm from bottom to top, wherein the size of 0.6mm is the diameter of the bioceramic microsphere;
[0025] Step 3. Import the five two-dimensional c...
