Embodiment Construction

[0031] Hereinafter, exemplary embodiments of the present invention will be provided by way of examples in order to fully convey the spirit of the present invention to those skilled in the art to which the present invention pertains. Therefore, the present invention is not limited to the embodiments disclosed herein.

[0032] Resin-based ceramic composites for 3D printing mainly include ceramic powder and resin slurry. Among them, the ceramic powder can preferably be selected from powders such as alumina, zirconia, aluminum nitride, silicon carbide, yttrium oxide, magnesium oxide, silicon oxide, calcium oxide, bismuth oxide, hydroxyapatite and tricalcium phosphate. one or several. In the present invention, in order to reduce the shrinkage rate during the molding process and suppress the occurrence of surface cracks, the ceramic composite material will be designed to have a high solid phase content. Preferably, the ceramic powder can account for 30-80% by volume of the ceramic...

Abstract

The invention discloses a structure-reinforced photocurable resin-based ceramic composite material and a degreasing method for a ceramic embryo body. By optimizing the design of the resin system, it is possible to increase the penetration depth of the ceramic slurry system and reduce the molding size error while maintaining the reactivity of the system; to increase the bonding force between the ceramic body layers and the bonding force between the printing platform and reduce The detachment of the ceramic green body from the platform and the cracks on the surface of the ceramic green body; at the same time, the tensile strength of the molded part is improved, so that the material can adapt to the printing requirements of suspension and microstructure.

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...
