High-precision photocuring 3D printing method for microlattice structure precursor conversion ceramic
The invention relates to a high-precision photocuring 3D printing method for microlattice structure precursor conversion ceramic, and relates to the technical field of 3D printing ceramic. The preparation method comprises the following steps: firstly, carrying out acrylic acid modification on epoxy silicone resin, then adding a photoinitiator and a light absorber, carrying out photocuring 3D printing and curing molding on the obtained system to obtain a micro-lattice structure precursor, and then carrying out pyrolysis treatment on the micro-lattice structure precursor to obtain the micro-lattice structure precursor converted ceramic. Integrally-formed photocuring 3D printing of the precursor conversion ceramic with the micro-lattice structure is achieved, the method has the advantages of being simple in preparation process and high in printing precision, and a direction is provided for high-precision machining of the precursor conversion ceramic with a complex structure.
本发明涉及一种微点阵结构先驱体转化陶瓷的高精度光固化3D打印方法，涉及3D打印陶瓷技术领域。本发明首先对环氧硅酮树脂进行丙烯酸改性，之后添加光引发剂和光吸收剂，对得到的体系进行光固化3D打印，固化成型后，得到微点阵结构先驱体，之后对其进行热解处理，即得微点阵结构先驱体转化陶瓷。本发明实现了微点阵结构先驱体转化陶瓷的一体成型光固化3D打印，具有制备工艺简单、打印精度高的特点，为具有复杂结构的先驱体转化陶瓷的高精度加工提供了方向。
