Beschreibung
Zusammenfassung:	The invention belongs to the field of biological materials, and discloses photosensitive resin/beta tricalcium phosphate composite biological ink capable of being used for DLP printing and a preparation method of the photosensitive resin/beta tricalcium phosphate composite biological ink. The preparation method comprises the following steps: carrying out surface treatment on beta tricalcium phosphate powder by using a silane coupling agent, mixing the beta tricalcium phosphate powder with photosensitive resin to prepare composite ink, carrying out photocuring 3D printing, and sintering to obtain the porous scaffold for bone tissue repair. The preparation method of the porous scaffold has the advantages of simplicity, short forming time and the like, and the scaffold with high pore connectivity and controllable shape and size can be conveniently obtained through structural design, so that the scaffold can be widely applied to the field of biomedicine. 本发明属于生物材料领域，公开了一种可用于DLP打印的光敏树脂/β-磷酸三钙复合生物墨水及其制备方法。将β-磷酸三钙粉末
