Description

technical field [0001] The invention relates to a 3D printing material and a preparation method thereof. Background technique [0002] With the emergence of 3D printing products, 3D printing technology is gradually being understood by people. 3D printing is also called rapid prototyping manufacturing technology. Its manufacturing process is to process the three-dimensional model layered and discretely, and transmit the data of each layer to the 3D printer. Metal and ceramic powders are processed by laser, ultraviolet light, and hot-melt nozzles. Materials such as plastics, cell tissues, etc. are piled up layer by layer and then bonded to shape, and finally the entire material or device is manufactured. 3D printing has the characteristics of simple manufacturing process, short product development cycle, easy to manufacture complex shape parts, multiple parts can be integrally formed, small part processing allowance, and material saving. Printing materials, which are the cor...
