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.

快速成型是一种离散、堆积成型的加工技术，其目标是将计算机三维CAD模型快速地转变为具体物质构成的三维实体模型。快速成型的基本过程是将计算机辅助设计的产品的立体数据(3D Model)，经电脑分层离散处理后，把原来的三维数据表层二维平面数据，按特定的成型方法，通过逐点逐面将成型材料一层层加工，并堆积成型。

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.

快速成型技术是将一个实体的复杂的三维加工离散成一系列层片的加工，大大降低了加工难度，开辟了不用任何刀具而迅速制作各类零件的途径，并为用常规方法不能或难以制造的模型或零件提供了一种新型的制造手段。南宁模型公司

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.

快速成型技术特点如下：

The characteristics of rapid prototyping technology are as follows:

1、改变了传统模型的制造方式，用CAD模型直接驱动实现设计与制造高度一体化，充分体现了设计评价制造的一体化思想，其直观性和易改性为产品的*设计提供了优良的设计环境。

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、可以制造任意复杂形状的三维实体模型，充分体现设计细节，尺寸和形状精度大卫提高，零件不需要进一步加工。

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、成型过程不需要工装模具的投入，既节省了费用又缩短了制作周期。

3. Molding process does not require the investment of tooling and die, which saves the cost and shortens the production cycle.

4、成型全过程的快速性适合现代激烈的产品市场。

4. The rapidity of the whole forming process is suitable for the fierce modern product market.
