Structure-enhanced photocurable resin base ceramic composite material and body degreasing method

Abstract

The invention discloses a structure-enhanced photocurable resin base ceramic composite material and a ceramic body degreasing method. Through optimal design of a resin system, while reaction activityof the system is maintained, the transmission depth of the ceramic slurry system is increased, and formation size errors are reduced; therefore, the interlaminar binding force of ceramic body and thebonding power between the ceramic body and a printing platform are increased, and separations of the ceramic body from the platform and cracks on the surface of the ceramic body are reduced; moreover,the tensile strength of a formed part is improved, so that the material can meet printing requirements of impending and fine structures.

Description

technical field

[0001] The invention relates to the field of ceramic materials, in particular to a photocurable resin-based ceramic composite material with improved tensile properties for additive molding and a degreasing method for a ceramic green body prepared therefrom. Background technique

[0002] Additive manufacturing (also known as "3D printing") is a manufacturing process that produces three-dimensional objects from digital files. In the process of 3D printing, layers of material are added one after another until the final object form is formed. Each layer can be regarded as a very thin cross-section of the object, and the thickness of each layer determines the printing accuracy. The smaller the layer thickness, the higher the printing accuracy, and the closer the printed entity is to the digital model itself .

[0003] The accuracy and efficiency of additive molding are closely related to additive materials, which are a research hotspot in the field of additive m...
