Rapid prototyping, also known as rapid prototyping, is an important part of modern advanced manufacturing technology. Rapid prototyping equipment can directly, quickly and accurately transform a design concept or design solution into an actual part prototype or directly manufactured part through the process of model building, approximation and slicing, providing an efficient and cost effective means of prototyping parts and verifying design concepts, making up for the shortcomings of traditional manufacturing methods.
Rapid prototyping technology is based on the principle of discrete/stack forming, where the CAD model is layered according to a certain thickness, turning the 3D model into a thin 2D flat model. The 2D model is then processed with data, machining parameters are added and each thin layer is machined continuously in a planar process under the control of a CNC system and bonded to form. There are a number of additive manufacturing methods, all of which manufacture parts layer by layer, the difference being that each method uses different materials and different bonding methods. Typical additive technologies are light-cured rapid prototyping (SLA), fused deposition (FDM), laser powder sintering (SLS) and laminated contouring (LOM).
Compared to traditional processing methods, additive technologies offer significant advantages in terms of speed, integration, applicability, adjustability and automation. For example: rapid prototyping enables fully automated forming, where only the operator has to enter the relevant parameters and the whole process can be run automatically without much intervention.
In recent years, rapid prototyping technology has developed significantly and is used in a wide range of applications, mainly in industrial manufacturing, the construction industry, the medical field, artistic creation, archaeological research, aerospace and other fields.
With the development of rapid prototyping technology, it is widely used in the mould making process. This technology allows for rapid prototyping of new products, with a production cycle time of only about 1/4 of that of traditional technology, and can effectively improve the success rate of mould making in one go. The technology is the conceptual design of the mould and production process in the CAD system can be integrated, the use of computer simulation analysis to form a new type of mould design and manufacturing system, without CNC cutting processing can be manufactured complex surfaces and other structures, is conducive to improve the manufacturing flexibility and quality of the mould.
In order to apply rapid prototyping technology as a new advanced manufacturing technology more widely in all walks of life, researchers still need to invest a lot of research and development on the basic theory and practical application. In the future, rapid prototyping technology will promote the development of related technologies, industries and so on.
