With the continuous development of manufacturing industry, the role of industrial fixture in the production process is increasingly prominent. As an important tool to fix the workpiece, ensure the machining accuracy and improve the production efficiency, the design and manufacturing quality of fixture directly affect the product quality and production efficiency. In recent years, the rapid development of 3D printing technology provides a brand-new solution for the manufacture of industrial fixtures. Compared with traditional manufacturing methods, 3D printing has obvious advantages in cost, design freedom and manufacturing cycle.
　　First, the limitations of traditional fixture manufacturing

Traditional industrial fixtures are mostly made of metal materials and processed by CNC machine tools, milling machines and other equipment. Although this method has high accuracy, there are many limitations. For example, the development cycle is long and the manufacturing cost is high; Design modification is difficult; Lack of flexibility for fixtures with complex structure or small batch requirements. In addition, metal fixtures are often heavy, which is not convenient enough for frequent replacement or manual operation.

Second, the advantages of 3D printing technology
　　3D printing (also called additive manufacturing) is a technology of stacking materials layer by layer to manufacture three-dimensional objects. Its application in fixture manufacturing is mainly reflected in the following aspects:

1. Rapid Prototyping and Customization Design

Through 3D modeling software, you can quickly design a personalized fixture structure that meets the specific process requirements and print it directly. Design modification only needs to adjust the model in the software, which greatly shortens the development cycle.

2. Integrated manufacturing of complex structures
　　3D printing can easily realize functional design such as internal hollowing and special-shaped structure, which makes the fixture light and strong. The structure that is difficult to realize by traditional technology can be easily printed in 3D.

3. The cost is low, and it is suitable for small and medium batch production.

For small batch or customized fixtures, 3D printing does not need to open the mold, which saves a lot of mold costs. At the same time, the use of engineering plastics or composite materials can also effectively reduce the material cost.

4. Lightweight and wear resistance

3D printing fixtures are made of polymer materials such as ABS, PLA and nylon, which have the advantages of light weight, wear resistance and corrosion resistance, and are suitable for various industrial environments.

Third, the typical application of 3D printing fixture

At present, 3D printing fixture has been widely used in automobile, electronics, aviation, medical and other fields. For example:
　　-Positioning fixture for assembly line in automobile manufacturing;

-Fixing and transporting precision parts in electronic product assembly;

-In the aerospace field, it is used to quickly manufacture special fixtures during testing and maintenance;

-Used as a teaching tool or experimental aid in teaching and research.

Fourth, the future development trend

With the continuous improvement of material science, printing accuracy and speed, 3D printing fixture will be applied in more high-end manufacturing fields. In addition, by combining artificial intelligence and automatic design platform, future fixtures will be more intelligent and efficient, and even realize "print on demand" intelligent manufacturing mode.

In a word, 3D printing has brought revolutionary changes to the manufacturing of industrial fixtures. It not only improves the manufacturing efficiency, but also reduces the cost and expands the design space, injecting new vitality into the modern manufacturing industry. With the continuous progress of technology, 3D printing fixture will play an increasingly important role in future industrial production.
