Preparation method of metal ceramic powder for 3D printing

The invention provides a preparation method of metal ceramic powder for 3D printing. The method comprises the following steps: step S10, carrying out wet grinding mixing reaction on a composition formed by mixing TiC powder and Ni powder and a forming agent to obtain a wet grinding mixture; step S20, carrying out spray drying reaction on the wet-ground mixture to obtain a spray mixture; step S30, screening the spray mixture to obtain a spray mixture with a target particle size; step S40, calcining the spray mixture with the target particle size in a vacuum environment to obtain metal ceramic powder; and S50, sieving the metal ceramic powder obtained in the step S40. Based on the technical scheme, the metal powder which is good in shape degree, stable in ceramic phase and suitable for 3D printing can be obtained, and the preparation method is low in cost, the particle size of the metal powder is controllable, the process is simple, and the production is convenient. 本发明提供了一种3D打印用金属陶瓷粉末制备方法，该方法包括：步骤S10、将由TiC粉末和N
