Abstract：Due to the complex internal structure and large size of some parts,the efficiency of welding after full processing or sectional or pingrocess the inner and outer surfaces of castings or bars is low,and the traditional casting is difficult to solve the problem of complex inner surface not processing.Using digital casting technology based on sand printing can reduce the development cycle of new products.It has the advantages of fast response speed,high flexibility,high precision and high process stability.
