Abstract

The invention discloses ceramic liquid for laser deposition moulding 3D printing and a preparation method and a using method thereof, relates to ceramic liquid for 3D printing and a preparation methodand a using method thereof, and aims to solve the technical problems of an obvious interlayer interface, low density and low strength of a ceramic material prepared by the existing liquid ceramic 3Dprinting method. The ceramic liquid comprises matrix resin, a viscosity regulator with the concentration of 2-5%, a photoinitiator, metal powder and ceramic powder, wherein the metal powder is copperpowder, gold powder, cobalt powder, nickel powder or iron powder. The preparation method comprises the following steps: uniformly stirring the components under ultrasonic assistance, and then debubbling in vacuum to obtain the ceramic liquid. The using method comprises the following steps: performing 3D printing with the ceramic liquid, and then sintering in the atmosphere to obtain a ceramic part, wherein the sintering temperature is higher than the melting point of the metal powder and lower than the boiling point of the metal powder. The ceramic liquid can be applied to the field of laser deposition moulding 3D printing.

Description

technical field [0001] The invention relates to a 3D printed ceramic liquid and methods for its preparation and use. Background technique [0002] The production of traditional ceramics is a complicated process. A ceramic product requires dozens of processes from the initial raw material processing to the final firing, which are interlocking and indispensable. The 3D printing technology of ceramics can greatly save time, simplify the process, and save a lot of labor costs, raw materials, and energy consumption. As a new technology, 3D printers solve many obstacles that traditional crafts cannot overcome, such as diversification, complexity, personalization, and high efficiency. At present, the methods of 3D printing ceramics mainly include layer-by-layer printing methods and liquid ceramic printing methods. The layer-by-layer printing method is suitable for printing most ceramics, but the printing accuracy is poor. Liquid ceramic 3D printing is the latest printing method ...
