The advantages of 3D printed sand casting compared to traditional sand casting

Sand casting is a traditional casting process that uses sand as the main molding material to make molds. Sand molds generally use gravity casting, and low-pressure casting, centrifugal casting, and other processes can also be used when there are special requirements. Sand casting has a wide range of adaptability, including small and large parts, simple and complex parts, as well as single and large quantities. Rapid casting technology combines 3D printing additive manufacturing technology. Compared with traditional casting processes, it does not require the production of wooden molds, patterns, etc. It has the advantages of short manufacturing cycles, low research and development costs, integrated manufacturing of sand molds and sand cores, and the ability to manufacture any complex shape mold or prototype. It can achieve overall near net forming of complex castings. Today, precision casting manufacturer Tianyao Metal will talk to you about the advantages of 3D printing sand casting and traditional sand casting.

1、 Short manufacturing cycle. 3D printing technology directly prints sand blocks based on the model, eliminating the process of mold design and processing, greatly reducing the construction period, and delivering raw materials in 10-20 days;

2、 High process flexibility. In the development stage of castings, it is necessary to continuously adjust the casting process, and mold modification is difficult. In the process improvement stage, 3D printing only requires direct modification of sand mold data to improve the efficiency of process research and development;

3、 Reduce the difficulty of forming and improve the dimensional accuracy of castings. 3D printing can print out parts of traditional parting sand blocks as a whole, simplifying the composition scheme of sand blocks while ensuring the dimensional accuracy of castings;

4、 The sand mold has good breathability and collapsibility. The sand mold prepared using 3D printing technology has a high porosity, is not only easy to clean, but also has good breathability, solves the problem of choking fire, and can directly print hollow sand cores, further improving exhaust capacity.

Compared with the traditional sand casting process, sand 3D printers have replaced traditional mold making, molding, and core making processes, reducing the difficulty of the process and greatly reducing the dependence on the technical level of workers. Moreover, sand 3D printers can print more complex sand molds and cores, freeing up design freedom. Due to direct printing of sand molds and cores, the casting cycle is greatly shortened, and equipment and personnel costs are also greatly reduced.

The above are the advantages of 3D printed sand casting compared to traditional sand casting.
