Rapid prototyping technology, also known as rapid prototyping technology, is an important part of modern advanced manufacturing technology. Rapid prototyping equipment can directly, quickly and accurately transform design concepts or design solutions into actual part prototypes or directly manufacture parts through the process of model building, approximation and slicing, providing an efficient and low-cost means of realization for part prototyping and verification of design concepts, making up for the shortcomings of traditional manufacturing methods.
Additive manufacturing technology is based on the principle of discrete/stack molding, where the CAD model is layered according to a certain thickness according to the 3D CAD model, turning the 3D model into a 2D flat model with a very thin thickness. The 2D model is then processed with data, processing parameters are added, and each thin layer is continuously machined and bonded to form in a planar process under the control of a CNC system. There are many additive manufacturing methods. All additive manufacturing methods manufacture parts layer by layer, but the difference is that each method uses different materials and different bonding methods. Typical additive manufacturing technologies are light-curing additive manufacturing (SLA), fused deposition (FDM), laser powder sintering (SLS) and laminated contouring (LOM).
Compared with traditional processing methods, rapid prototyping technology has significant advantages in terms of speed, integration, applicability, adjustability and automation. For example, rapid prototyping technology achieves fully automated molding, requiring only operator input of relevant parameters, and the entire process can be run automatically without much interference.
In recent years, rapid prototyping technology has been greatly developed, and it involves a wide range of fields and many application industries, mainly focusing on industrial manufacturing, construction industry, medical field, art creation, archaeological research, aviation space and other fields.
With the development of rapid prototyping technology, it is widely used in the process of mold manufacturing. This technology can carry out rapid trial production of new products, and the production cycle is only about 1/4 of the traditional technology, which can effectively improve the success rate of mold manufacturing once. This technology is the conceptual design of the mold and production process in the CAD system can be integrated, the use of computer simulation analysis to form a new mold design and manufacturing system, without CNC cutting processing can be manufactured complex surfaces and other structures, which is conducive to improving the manufacturing flexibility and quality of the mold.
In order to apply the 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, practical application and other aspects. In the future, rapid prototyping technology will promote the development of related technologies, industries, etc.
