| Abstract: | According to the characteristics of 3D printing sand mold(core), the effects of suspending agent and binder on the rheology of 3D printing sand mold(core) water-based coating were studied, and the optimal formulation was received. The influence of coating drying temperature on the strength of sand mold was tested, and the optimal drying temperature was determined. Practical applications of research results suggest that the coating is homogeneous and smooth, and the castings produced have good surface finish. |
