| titleOfInvention | Novel BT/HA biphase piezoelectric biological ceramic bone tissue engineering restoration and preparation method thereof |
| abstract | The invention discloses a novel BT/HA biphase piezoelectric biological ceramic bone tissue engineering restoration and a preparation method thereof. The method comprises the following steps: preparing BT and HA slurry respectively; designing a communicating means for connecting the two printing cartridges; printing the piezoelectric bio-ceramic bone tissue engineering scaffold by a melt extrusion 3D printer (FDM) capable of simultaneously printing a plurality of material cylinders; and drying the printed support, and sintering at high temperature in an air atmosphere to obtain the piezoelectric biological ceramic support. The invention has the following beneficial effects: 1. the two material cylinders filled with different sizing agents are connected by the communication device, so that the same fiber extruded by the 3D printer has continuous two phases, and compared with the traditional single material cylinder extrusion printing, a novel composite mode of a bi-component material is created, so that the constructed bracket has a new structure; 2. the content of HA/BT can be freely adjusted by adjusting the viscosity of the two slurries without destroying the continuity of the piezoelectric phase. |
