1.Overview of sand 3D printing technology
Sand 3D printing is a technology based on a three-dimensional computer-aided design (CAD) model that achieves manufacturing molding by stacking sand mold materials layer by layer. Its biggest advantage is that it can achieve high-precision manufacturing of complex shapes, which greatly shortens the manufacturing cycle and reduces manufacturing costs. In traditional sand mold manufacturing, it is necessary to make a mold or model first, and then carry out steps such as sand filling, compaction, and molding, while sand mold 3D printing can complete these tasks in a few hours, and there is no need for professional technicians to operate.
2.A new breakthrough in the application of sand mold 3D printing
(1)Efficient manufacturing: Sand 3D printing can achieve efficient manufacturing, especially for some parts with complex shapes. For example, in the aerospace field, many parts have complex internal structures and shapes that are difficult to achieve with traditional manufacturing methods, and sand 3D printing can easily solve these problems. In addition, sand 3D printing can also greatly shorten the manufacturing cycle, especially when parts are urgently needed.
(2)Customized production: Sand 3D printing technology can achieve customized production to meet the personalized needs of customers. For example, in the medical field, high-precision medical devices such as prostheses and teeth can be customized according to the needs of patients, and in the automotive field, the exterior and interior structure of the car can be customized according to personal preferences. This customized production method can not only meet customer needs, but also improve the added value and market competitiveness of products.
(3)Green manufacturing: Sand 3D printing technology can achieve green manufacturing and reduce waste generation and environmental impact. In the traditional manufacturing process, a large amount of waste and waste will be generated, while sand 3D printing can increase the utilization rate of raw materials to more than 90% and reduce the waste of natural resources. In addition, sand mold 3D printing can also use waste sand as a raw material to transform waste into useful products, realizing the recycling of resources.
(4)Intelligent manufacturing: Sand 3D printing technology can be combined with digital and intelligent technology to achieve intelligent manufacturing. Through the integration of technologies such as the Internet of Things, big data, and cloud computing, the production process can be automated, remotely monitored, and optimized. This intelligent manufacturing method can improve production efficiency and product quality, reduce production costs and energy consumption.
(5)Biocompatibility: Sand 3D printing technology can also be used to make biocompatible products. For example, in the medical field, sand 3D printing technology can be used to create biocompatible prosthetics, teeth, and other medical devices. These medical devices can be perfectly integrated with human tissues to improve the quality of life of patients. In addition, sand 3D printing technology can also be used to create models of biological tissues to support medical research and treatment.
(6)Applications in the construction field: In the construction field, sand 3D printing technology can be used to manufacture architectural models and components. Traditional architectural model making requires the use of a large amount of wood, plastic and other materials, while sand 3D printing can use sand as a raw material to produce high-precision architectural models and components. In addition, sand 3D printing can also be used to manufacture decorations and components in buildings, improving the appearance and quality of buildings.
(7)Applications in the aviation field: In the aviation field, sand 3D printing technology can be used to manufacture aircraft parts and models. Due to the complex shape and internal structure of aircraft parts, which are difficult to achieve by traditional manufacturing methods, sand 3D printing can easily produce these complex parts and models. In addition, sand 3D printing can also be used to manufacture prototypes and test pieces of aircraft parts, speeding up aircraft research and development and reducing costs.
In this paper, the new breakthrough in the application of sand 3D printing is discussed and analyzed. Through the application of efficient manufacturing, customized production, green manufacturing, intelligent manufacturing, etc., sand 3D printing technology has become an important branch of modern manufacturing. With the continuous progress of technology and the continuous expansion of application fields, it is believed that sand 3D printing technology will play a more important role in the future.
