Abstract

The invention discloses a ceramic 3D printing material based on selective laser sintering and a preparation method of the ceramic 3D printing material. The ceramic 3D printing material comprises the following components in parts by mass: 65-79 parts of ceramic particles, 10-20 parts of thermoplastic resin, 10-20 parts of ceramic frit and 1-10 parts of a coloring material, wherein the resin, the ceramic frit and the coloring material are powdery. During preparation, the ceramic particles and the powdery resin, ceramic frit and the coloring material are added into a stirrer in proportion for stirring, and are mixed uniformly to obtain a needed printing material. According to the preparation method provided by the invention, the ceramic frit is added during preparation to fill pores so as to improve the compactness of a printed product, and the printing material is stable in performance during printing and more uniform during sintering; moreover, the prepared material has simple components, and is convenient to manufacture, good in using effect, high in strength and easy to promote.

Description

technical field [0001] The invention relates to a 3D printing material and a preparation method thereof, in particular to a ceramic 3D printing material based on selective laser sintering and a preparation method thereof, belonging to the technical field of ceramic materials. Background technique [0002] 3D printing technology is currently an emerging rapid prototyping technology. It is a technology based on digital model files, using powder materials, filaments, pastes and other materials to construct objects by layer-by-layer printing. With the development and application of 3D printing technology, materials have become one of the key factors limiting the future direction of 3D printing technology. To a certain extent, the development of materials determines whether 3D printing can be more widely used. At present, 3D printing materials mainly include polymer materials, metal materials, inorganic non-metal materials and food materials. [0003] The raw material used in th...
