Problems solved by technology

When using 3D printing technology to form ceramic products, the 3D printing materials used are all ceramic powders fired from clay, and then ceramic products are obtained by direct or indirect methods, but the preparation methods of ceramic powders are complex and costly , which seriously hinders the development and application of 3D printing technology in ceramic molding
Clay itself has excellent viscosity and plasticity, and can be directly formed into a ceramic green body, and then sintered to obtain ceramics. However, due to defects in technology and technology, the molded ceramic green body has shortcomings such as simple structure and poor dimensional accuracy, which severely limits the use of clay. For the application of clay and its products in daily life, if 3D printin

Description

technical field [0001] The invention relates to a 3D printing material and a preparation method thereof, in particular to a clay material for 3D printing and a preparation method thereof. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is an emerging technology in the field of rapid prototyping. It is based on digital model files and uses bondable materials such as powdered metal or plastic to print layer by layer. Techniques for constructing objects. With the development and application of 3D printing technology, materials have become one of the key factors limiting the future direction of 3D printing technology. To a certain extent, the development of materials determines whether 3D printing can be more widely used. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials, and ceramic materials. The field of printing has been applied. [0003] As...
