Preparation method of high-density crystal nucleus assembled spherical beta-TCP powder for additive manufacturing
The invention relates to a preparation method of high-density crystal nucleus assembled spherical beta-TCP (beta-tricalcium phosphate) powder for additive manufacturing. The preparation method comprises the following steps: firstly, selecting a green and environment-friendly calcium source and a phosphorus source, preparing the calcium source and the phosphorus source into precursor powder under a water bath heating condition, and regulating and controlling crystal nucleus growth; secondly, mixing and stirring the ceramic precursor, a polymer and a solvent to obtain spray-dried slurry, and performing spray drying to obtain a crystal nucleus assembled spherical precursor; and finally, carrying out calcination treatment to obtain the high-density crystal nucleus assembled spherical beta-TCP. The beta-TCP synthesized by the method disclosed by the invention is spherical powder assembled by high-density crystal nuclei, has good fluidity and dispersibility, can be applied to a preparation process of 3D printing slurry, effectively improves the solid content and uniformity of the printed material, realizes the consistency of the overall performance of a printed piece, and is suitable for industrial production. And the method has a wide application prospect in the fields of artificial bone scaffold personalized customization, related ceramic 3D printing and the like.
本发明涉及一种增材制造用高致密晶核组装的球形β‑TCP(β‑磷酸三钙)粉体的制备方法：首先选择绿色环保的钙源与磷源，将其在水浴加热条件下制备成前驱体粉末，调控晶核生长；其次将陶瓷前驱体、聚合物与溶剂混合搅拌，得到喷雾干燥浆料，进行喷雾干燥，获得晶核组装的球形前驱体；最后煅烧处理后得到高致密晶核组装的球形β‑TCP。本发明合成的β‑TCP为高致密晶核组装的球形粉体具有流动性、分散性好，可应用于3D打印浆料的配制过程，有效提高所打材料的固含量、均匀性，实现打印件整体性能的一致性，在人工骨支架个性化定制及相关陶瓷3D打印等领域有广阔的应用前景。
