Recently, the precision casting industry has experienced a major breakthrough. With the application of 3D printing technology, the casting process can be further optimized, bringing a more efficient and precise production method to the manufacturing industry. The traditional precision casting process requires multiple steps such as mold making, melting casting materials, injection into the mold, cooling and solidification, etc., and requires a lot of manual operations. This process is not only time-consuming and labor-intensive, but also prone to problems such as mold wear and casting deformation, which affects product quality. The application of 3D printing technology can solve these problems. Through 3D printing technology, the precision casting industry can directly transform design drawings into physical products without making molds. This not only greatly shortens the production cycle, but also reduces production costs. At the same time, 3D printing technology can realize the manufacturing of castings with complex structures, improving the accuracy and quality of products. In addition to improving production efficiency and product quality, 3D printing technology also brings more innovative possibilities to the precision casting industry. The traditional casting process is limited by the production and design of molds, making it difficult to manufacture products with complex shapes and structures. 3D printing technology can realize free-shape design and manufacturing, providing more possibilities for product innovation. In addition, 3D printing technology can also achieve small batch and personalized production. The traditional casting process requires the production of a large number of molds and is suitable for mass production
