Rapid prototyping technology in model making, also known as rapid prototyping or solid free-form manufacturing, is a method of making basic parts layer by layer with materials. It is a product design and development technology developed by integrating new technologies such as CAD, CNC, precision machinery, laser technology and material science and engineering. There are still many people who don't know much about it. Next, let's give you a detailed introduction of the principle and advantages of rapid prototyping technology in model making.
Rapid prototyping (RP) is a discrete and stacked prototyping processing technology. Its goal is to rapidly transform the computer three-dimensional CAD model into a three-dimensional solid model composed of specific substances. The basic process of rapid prototyping is to process the three-dimensional model of computer-aided design products by layering and discretizing the original three-dimensional data surface two-dimensional plane data, according to the specific forming method, through point-by-point and side-by-side processing of forming materials, and stacking forming.
Rapid prototyping technology is to separate the complex three-dimensional processing of an entity into a series of layers, which greatly reduces the difficulty of processing, opens up a way to rapidly manufacture various parts without any tool, and provides a new manufacturing method for models or parts that cannot or cannot be manufactured by conventional methods.

The characteristics of rapid prototyping technology are as follows:
1. Changing the manufacturing mode of traditional models, the integration of design and manufacturing is realized by using CAD model to drive directly, which fully embodies the integration idea of design evaluation and manufacturing. Its intuition and easy modification provide a good design environment for the perfect design of products.
2. Three-dimensional solid model with arbitrary complex shape can be manufactured, which fully reflects the design details. The accuracy of size and shape is improved by David, and the parts need not be further processed.
3. Molding process does not require the investment of tooling and die, which saves the cost and shortens the production cycle.
4. The rapidity of the whole forming process is suitable for the fierce modern product market.
