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.

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 printing technology is used for clay and then molded to obtain ceramics, the above-mentioned defects can be completely improved and solved. Therefore, the application of clay and its products in daily life Significant and market value

[0004] Since the plasticity and mechanical properties of clay are opposite, unmodified clay materials are not suitable for 3D printing. High plasticity clay has poor mechanical properties, which is not conducive to support and modeling during the molding process, while good mechanical properties Clay has poor cohesiveness and plasticity, which is not conducive to bonding and extrusion during the molding process. Therefore, it is necessary to modify the clay to obtain a clay material suitable for 3D printing technology before applying clay to 3D printing.
