6 Problems Existed in the Rapid prototype Manufacturing

After the 1990s, the external situation of the manufacturing industry has undergone fundamental changes. Enterprises need to adopt multiple varieties, small batches, and modern production methods to adapt to the user's individualized and versatile needs. At the same time, the globalization and integration of the market require companies to be highly sensitive and adapt to the market environment; They need to develop new products quickly and take the initiative to guide the market. Companies that can quickly deliver higher performance products will have greater overall competitiveness.

 

Under this environment, rapid prototype technology has emerged. Rapid prototype technology is an important branch of advanced manufacturing technology, with great breakthroughs in both manufacturing ideas and implementation methods. Designers use rapid prototype technology to quickly evaluate, modify, and quickly convert a design into a prototype with the appropriate structure and function or to directly manufacture parts. Due to the characteristics of rapid prototype technology, it is used In all areas, the process of implementation is not all smooth, and there will be difficulties and obstacles.

 

Technological Problem

The basis of rapid prototype is the principle of layered superposition. However, what material is used for layered superposition and how to carry out layered superposition needs to be studied. Therefore, in addition to the above-mentioned common layered superposition forming method, engineers are researching and developing some new layered superposition forming methods to further improve the performance of the parts and improve the forming precision and forming efficiency.

 

 

Material Problem

Molding materials have always been a hot issue, and the properties of rapid prototype materials must meet:

1. The material is convenient for rapid and precise processing;

2.The material used for rapid prototype system to directly manufacture functional parts should be close to the requirements of strength, stiffness, moisture resistance and thermal stability of the final use of the part;

3.The materials selected need to be suitable for the subsequent processing of rapid mold making. Develop new materials, especially composite materials such as nanomaterials, heterogeneous materials, etc.

 

 

Precision Problem

The accuracy of rapid prototype is typically at a level of ±0.1 mm, especially for height accuracy. The basic principle of rapid prototype technology determines that the process is difficult to achieve the surface quality and precision index with traditional machining. Combining the basic forming idea of rapid prototype with traditional machining methods is an important method to improve the precision of rapid prototype.

 

 

Energy Problem

The energy used in rapid prototype technology is light, heat, chemical, and mechanical energy. Further improvements are needed in terms of energy density, fineness of energy control, and quality of molding processing.

 

 

Application Domain Problem

The application field of rapid prototype technology mainly lies in the development of new products. The main function is to shorten the development cycle and obtain the effect of market feedback as soon as possible.

 

Due to the great appeal of rapid prototype technology, not only the industrial industry attaches great importance to it, but many other industries are committed to its application and promotion. After its technology has made progress toward higher precision and better material performance, It can be considered to join the fields of biomedicine, archaeology, cultural relics, art design, architectural molding and other fields to form a high efficiency, high quality, high precision replication process system.
