Abstract

The invention provides a ceramic material for 3D printing and a preparation method thereof, comprising the following components by weight: 50-150 parts by weight of zirconia powder; 10-30 parts by weight of zirconia powder treatment agent; 100-500 parts by weight of dispersion medium 1-10 parts by weight of single crystal sapphire whiskers; 1-10 parts by weight of stabilizer; 5-50 parts by weight of photocuring agent. The invention can significantly improve the flexural elastic modulus and tensile strength of the product by adding single-crystal sapphire whiskers to the zirconia ceramics, and is used for preparing high-strength, high-toughness fine engineering ceramics.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a method for preparing ceramic materials for 3D printing. Background technique [0002] The principle of 3D printing technology is stacked manufacturing, which is a technology that increases materials layer by layer to generate three-dimensional entities, so it is also called additive manufacturing technology. In recent years, additive manufacturing technology has developed rapidly and has had a huge impact on the manufacturing industry. It has received great attention from countries all over the world. It has been hailed as another industrial revolution that subverts traditional manufacturing and has been included in my country's strategic emerging industries. [0003] 3D printing mainstream molding technologies include selective laser sintering (SLS), fused deposition modeling (FDM), stereolithography (SLA), etc. Selective laser sintering was successfully develop...
