Embodiment 1
[0048] A method for preparing a biomimetic bioceramic with a through-hole structure in this embodiment includes the following steps:
[0049] (1) Preparation of the mould: use a cylindrical mold body with an inner diameter of 20 mm and a height of 80 mm and the matching top cover and bottom plate. Ethylene, the mold body, the top cover and the bottom plate form a mold cavity, and the bottom plate is fixed with needle-shaped cylindrical wires with a diameter of 500 microns and an interval of 1 mm, and the metal wires extend to the top cover in the mold cavity;
[0050] (2) Preparation of plastic porous support: Fill ABS plastic particles with a diameter of 300 μm to 400 μm into the mold cavity from the upper opening of the mold body, and heat in an oven at 180°C for 30 minutes to melt the surface of the ABS plastic particles and bond them to each other. , then take out the mutually bonded ABS plastic particles together with the base plate and the wire from the mold cavity, cool...
