Abstract

The invention provides a ceramic material for 3D printing and a preparation method thereof. The ceramic material is prepared from, by weight, 50-150 parts of zirconia powder, 10-30 parts of zirconia powder treating agents, 100-500 parts of dispersion media, 1-10 parts of single-crystal sapphire whisker, 1-10 parts of stabilizing agents and 5-50 parts of light curing agents. The single-crystal sapphire whisker is added into the zirconia ceramics, so that the modulus of elasticity in static bending and the tensile strength of the product are significantly improved, and the preparation method is used for preparing high-strength and 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...
