High-solid-content photocuring 3D printing biological ceramic slurry and preparation method thereof
The invention discloses a high-solid-content photocuring 3D printing biological ceramic slurry and a preparation method thereof, and the biological ceramic slurry comprises the following components by weight: 50-80 wt% of biological ceramic powder, 10-33 wt% of a resin monomer, 1-5 wt% of a dispersant, 1-3 wt% of a photoinitiator, 1-7 wt% of a leveling agent, and 1-7 wt% of an antifoaming agent. The biological ceramic slurry has the advantages of high solid content, low viscosity, high dispersity and simple process; the problems that due to secondary agglomeration of existing photocuring 3D printing biological ceramic slurry, slurry dispersion is uneven, and normal printing cannot be achieved, and due to the fact that the solid content of existing biological ceramic slurry is insufficient, mechanical strength is insufficient, printing precision is low, and deformation, cracking and layering are caused after sintering are solved.
本发明公开了一种高固含量光固化3D打印生物陶瓷浆料及其制备方法，该生物陶瓷浆料组成成分按照重量百分比划分，由50～80wt％生物陶瓷粉末、10～33wt％树脂单体、1～5wt％分散剂、1～3wt％光引发剂、1～7wt％流平剂、1～7wt％消泡剂组成。该生物陶瓷浆料具有高固含量、低粘度、高分散性，工艺简单的优点，解决了现有光固化3D打印生物陶瓷浆料出现二次团聚导致浆料分散不均无法正常打印的问题及现有生物陶瓷浆料固含量不足导致的力学强度不足、打印精度低、烧结后变形、开裂、分层的问题。
