[0003] Hydroxyapatite is a bioactive material with a porous bone tissue structure and excellent biocompatibility. It can interact with biological tissues. Reasonable use of this material generally has no obvious harm to the human body. Hydroxyapatite can be used as a bone repair material, which can promote bone tissue regeneration and repair, and can be used for bone tissue repair such as fractures and bone defects. It can also be used for tooth repair, implantation, etc. When hydroxyapatite is made into a shape coating suitable for human bones, a 3D printing device is required;
