Application of 3D Printing Sand Core in Casting Forming of Aerospace Thin-walled Structural Part

Qiu Hui;Li Xingguang;Shu Junlin;Guizhou Aerospace Fenghua Precision Equipment Co.,Ltd.;  
The thin-walled structure part for aerospace were manufactured based on 3 Dprinting sand core by differential pressure casting technology.The results show that the sand core manufactured by 3 DP technology has high precision,uniform sand mold strength and good deformability.The internal quality of the thin-walled structure casting part with the high dimension precision of the shape structure using3 DP technology meets the design requirements.
