This technology can effectively promote the industrial upgrading and transformation of the foundry industry, while improving resource utilization and achieving energy conservation and emission reduction to meet the needs of my country’s modern social development.。
Sand mold 3D printing technology principles and advantages
3D printing technology is a manufacturing method that uses digital models as a basis to print materials layer by layer through adhesives. The difference from traditional manufacturing methods is that 3D printing technology does not require the production of molds. It only relies on computers to quickly and effectively produce sand molds of any shape.
During the sand mold making process, we use 3D printing equipment to spray the adhesive on the sand powder. After forming a solidified interface, we spray the next layer of sand powder and repeat the above operation. Compared with traditional manufacturing methods, sand 3D printing has a simpler production process and higher production efficiency.
Application prospects of sand mold 3D printing technology
Since sand 3D printing technology simplifies the production process of sand castings and reduces the mold and mold modeling process, 3D printing can effectively shorten the research and development cycle and greatly reduce various expenses in the field of new product research and development and small batch production. investment and has extremely high application value.
For example, there are relatively refined and complex cylinder blocks and heads for automobile engines, large and medium-sized complex metal castings for aircraft, and heat-resistant alloy parts used in rocket missiles. The traditional sand casting process has some difficulties in meeting these requirements. It requires manufacturing complex molds to achieve complex curved surfaces of castings, which increases the manufacturing cycle and difficulty and limits the production of products with personalized appearance. Sand 3D printing technology can solve problems that cannot be solved by traditional processing technology. The more complex products are manufactured, the more cost advantages there are. In the field of complex product manufacturing and high value-added products, its advantages are very obvious.
At the same time, sand 3D printing technology can also print complex sand cores, which can be combined with traditional mold manufacturing. Sand cores are often very complex components that require additional molds or core boxes to manufacture.

Using sand 3D printing technology, manufacturing companies can meet market demands more flexibly. It not only enables the production of complex-shaped castings, but also quickly adjusts and updates the design to adapt to the rapidly changing market environment. This is particularly important for industries with diverse and personalized customization needs, such as aerospace and automobile manufacturing.
