3D printed magnetic biological ceramic scaffold and preparation method thereof
The invention discloses a 3D printed magnetic biological ceramic scaffold which is prepared by taking biological ceramic powder, magnetic nano powder and a printing aid as main raw materials and sequentially carrying out 3D printing and degreasing sintering according to a three-dimensional scaffold model. According to the invention, a 3D printing technology is adopted, a magnetic nano material isfurther introduced into a biological ceramic material system by combining a liquid drying method and a two-step sintering method, so that the3D printed magnetic biological ceramic scaffold is endowedwith a magnetic effect which is not possessed by a traditional biological ceramic scaffold, the shape control and on-demand customization of the biological ceramic scaffold can be realized, and the biological ceramic scaffold is expected to be used for treating bone tumors and repairing bone defects; and the related preparation method is simple, wide in material source and suitable for popularization and application.
本发明公开了一种3D打印磁性生物陶瓷支架，它以生物陶瓷粉、磁性纳米粉和打印助剂为主要原料，根据三维支架模型，依次进行3D打印和脱脂烧结而成。本发明采用3D打印技术，并结合液体干燥法和两步烧结法在生物陶瓷材料体系中进一步引入磁性纳米材料，可赋予传统生物陶瓷支架不具备的磁效应，并可实现生物陶瓷支架的控形控性和按需定制，有望用于骨肿瘤的治疗和骨缺损的修复；且涉及的制备方法简单、材料来源广，适合推广应用。
