According to the nano-powder material for 3D printing, the components of the nano-powdermaterial mutually exert a synergistic effect to improve the product quality, so that the nano-powder material for 3D printing has wide application.

Description

technical field [0001] The invention belongs to the technical field of rapid prototyping materials, and in particular relates to a nano-powder material for 3D printing and a preparation method thereof. Background technique [0002] Three-dimensional printing (Three Dimonsion Printing, referred to as 3D) is a rapid prototyping technology, which can divide the three-dimensional model data designed by the computer into layer model data, and accumulate specific raw materials layer by layer until the construction of the entire entity is completed. 3D molding has the advantages of low cost, no pollution in the working process, and fast molding speed. [0003] With the rapid development of science and technology, rapid prototyping technology has been widely used in various fields of life. At present, the materials used for 3D printing are basically plastic materials, metal materials or ceramic-based materials. The cost is relatively high, which has caused a great impact on the comp...
