Rubber coating powder for additive manufacturing as well as preparation method and application of rubber coating powder
The invention relates to rubber coating powder for additive manufacturing and a preparation method and application thereof. The rubber coating powder comprises a core and a coating shell. The core is material powder for a 3D printing forming body, and the particle size of the material powder is larger than 0 mu m and smaller than or equal to 150 mu m; the coating shell is glue, the thickness of the coating shell of the metal powder is larger than 0 mu m and smaller than or equal to 10 mu m, and the thickness of the coating shell of the ceramic powder is larger than 0 mu m and smaller than or equal to 6 mu m; the surface of the encapsulation powder is compact and free of holes; according to the fluidity of the rubber coating powder, metal is smaller than or equal to 70 s/50 g, and ceramic is smaller than or equal to 90 s/50 g. The rubber coating powder is used for additive manufacturing, the strength of green bodies is enhanced, and the yield of the green bodies is increased; in the process of printing and powder laying, low-power laser curing forming can be adopted, the requirement for equipment components is greatly lowered, the stability of 3D printing equipment is improved, the service life of the 3D printing equipment is prolonged, and large-scale industrial production is easy to achieve.
本发明涉及一种用于增材制造的包胶粉末及其制备方法和用途，包胶粉末包括核芯和包覆壳；核芯为用于3D打印成型体的材料粉体，材料粉体的粒径大于0μm小于等于150μm；包覆壳为胶水，金属粉体的包覆壳厚度大于0μm小于等于10μm，陶瓷粉体的包覆壳厚度大于0μm小于等于6μm；包胶粉末的表面致密且无孔洞；包胶粉末的流动性：金属小于等于70s/50g，陶瓷小于等于90s/50g。本发明的包胶粉末用于增材制造中，增强了生坯强度，提高了生坯良品率；在打印铺粉过程中，可采用低功率激光固化成型，对设备组件的要求大大降低，提高了3D打印设备的稳定性和使用寿命，容易实现大批量、工业化生产。
