High-precision ceramic 3D printing slurry as well as preparation method and application thereof
The invention provides high-precision ceramic 3D printing slurry as well as a preparation method and application thereof. The high-precision ceramic 3D printing slurry comprises the following components: ceramic powder; a photosensitive resin; a dispersant; an ultraviolet absorbent; a composite plasticizer; a hydrogen abstracting type photoinitiator; a curing accelerator; the light absorption amount of the ceramic slurry is effectively reduced, the light overflow phenomenon is reduced, the light energy utilization efficiency in the printing process is improved, the curing width is guaranteed, the curing depth is guaranteed, and the problem that the strength of a printed product is low due to insufficient curing is solved; in addition, in the degreasing stage, forming of a degreasing hole channel is facilitated, so that the photosensitive resin is smoothly discharged, and the problem of cracking of the product is avoided; high-precision photocuring 3D printing forming is achieved, and the product precision and the mass production quality are improved.
本发明提供一种高精度陶瓷3D打印浆料及其制备方法、应用，包括以下组分：陶瓷粉体；光敏树脂；分散剂；紫外吸收剂；复合增塑剂；夺氢型光引发剂；固化促进剂；不仅有效降低了陶瓷浆料对光的吸收量，减少了光的外溢现象，从而提高了打印过程中的光能利用效率，保证了固化宽度，而且同时保证固化深度，从而避免了因固化不足导致的打印产品强度偏低的问题出现；并且在脱脂阶段有利于形成脱脂孔道，使得光敏树脂顺利地排出，避免了产品的开裂的问题出现；实现了高精度的光固化3D打印成型，提高了产品的精度和批量化生产的质量。
