Embodiment Construction

[0027] 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.

[0028]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 photocurable resin-based ceramic composite material and a ceramic green body degreasing method. By optimizing the design of a resin system, the method increases the penetration depth of a ceramic slurry system and reduces the molding dimensional error while maintaining the system reaction activity; furthermore, the interlayer bonding force of a ceramic green body and theadhesion between the ceramic green body and a printing platform are improved, and the detachment between the ceramic green body and the platform as well as the cracks on the surface of the ceramic green body are reduced.

Description

technical field [0001] The invention relates to the field of preparation of ceramic materials, more specifically to a light-cured resin-based ceramic composite material 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 materials 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 precision and efficiency of additive molding have a very close relationship with additive materials, and additive materials are a research hotspot in the fi...
