of Descriptions nThe present invention discloses a 3D printing device for bionic bone scaffolds made of porous ncontinuous carbon fibers reinforced ceramics and its method. The device described in the present ninvention combines a pretreatment device of continuous fiber with a ceramic slurry extrusion device, nand thus, the integrated design of 3D printing device for bone scaffolds made of carbon fibers nreinforced ceramics can be accomplished. Furthermore, the fiber pretreatment material utilized in nthe method of the present invention is the ceramic slurry with the same base material and relatively nlow solid content. Wherein, the ceramic slurry with relatively low solid content has better nwettability, which can not only adhere to the external of the carbon fiber multifilament, but also npenetrate in the internal of carbon fiber multifilament, and thus the adhesive action can be naccomplished, and further it can improve the biological properties of the composite material. |
