Description

technical field [0001] The invention belongs to the field of biomedical materials, and in particular relates to a bioactive 3D printing ceramic and a preparation method thereof. Background technique [0002] As an emerging manufacturing technology, 3D printing has been applied to all walks of life after rapid development in recent years. Due to its unique molding advantages, it has an irreplaceable position in the medical industry. Among them, selective laser sintering (SLS) technology has been applied to the manufacturing and molding of metal medical devices, and the treatment effect has shown more satisfactory results than traditional processes. Commonly used 3D printing technologies include fused deposition modeling (FDM) and stereolithography (SLA) technologies, among which SLA has higher precision and can complete more complex model printing. [0003] The main components of traditional bioceramic materials are calcium phosphate and hydroxyapatite. This type of ceramic ...
