Abstract

The inventiondiscloseslean ceramic powder size for direct-forming 3D ceramic printing. The lean ceramic powder size is prepared from lean ceramic powder, a composite thixotropic agent, a dispersing agent, a thickening agent, a levelling agent and deionized water in a mass ratio being (65-75):(0.2-0.6):(0.9-1.3):(2.0-5.0):(0.5-1.5):(15-30); the lean ceramic powder is one or combination of Al2O3, ZrO2, SiC and Si3N4. The invention further discloses a preparation method and an application of the lean ceramic powder size. The lean ceramic powder size has high solid content and high shear thinning performance, is suitable for preparation of 3D printing ceramic devices with direction forming process and can be gradually dried and cured in a 3D printing process at the room temperature, and accordingly, a set structure is obtained without collapse, the printing precision is high, and the requirement for 3D printing direct-forming can be well met.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a sterile ceramic powder slurry for direct molding 3D ceramic printing and its preparation method and application. Background technique [0002] 3D printing technology is a technology to manufacture three-dimensional products by adding materials layer by layer through 3D printing equipment based on the designed 3D model. This layer-by-layer accumulation forming technology is also called additive manufacturing. 3D printing integrates digital modeling technology, electromechanical control technology, information technology, material science and chemistry and many other fields. It is a kind of rapid prototyping technology and is known as the core technology of the "third industrial revolution". [0003] 3D printing materials mainly include plastics, metals, resins, rubber, ceramics, etc. Among them, ceramic materials have excellent characteristics such as high strength, high ha...
