The reason is that the rapid tooling manufacturing process is characterized by the combination of rapid prototyping technology and traditional technology, which complements each other and shortens the design and manufacturing cycle of the mold. The time required for rapid tooling from conceptual design to mold ejection is about one third of that required by traditional tooling methods.
The main advantage of prototype method is that it is a method to support users and make users play an active role in the design stage of system life cycle; It can reduce the risk of system development, especially in the development of large-scale projects, because it is difficult to complete the analysis of project requirements at one time, the effect of applying prototype method is more obvious. The concept of prototype method is not only applicable to the redevelopment of the system, but also applicable to the modification of the system.
Extended data:
Rapid prototyping The most typical process of directly manufacturing molds by rapid prototyping technology is the patented RapidToll technology of American DTM company, which can manufacture injection molds for production within 5 to 10 days. The hardness of the inner cavity of the die is higher than 75HRC. If used correctly, more than 50 thousand parts can be injected, which belongs to the mold that can be directly used for mass production.
The prototype method is not limited to the computer aspect of the design and development project, and the working model of the system is made by the third-layer prototype method. The success of rapid prototyping needs the support of a good development environment/tool like the fourth generation language (4GL).
Prototype method can be combined with traditional life cycle method, which will expand users' participation in requirements analysis, preliminary design and detailed design and deepen users' understanding of the system. In recent years, the idea of rapid prototyping method has also been applied to product development activities.
