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.

快速成型是一種離散、堆積成型的加工技術(shù)，其目標(biāo)是將計(jì)算機(jī)三維CAD模型快速地轉(zhuǎn)變?yōu)榫唧w物質(zhì)構(gòu)成的三維實(shí)體模型。快速成型的基本過程是將計(jì)算機(jī)輔助設(shè)計(jì)的產(chǎn)品的立體數(shù)據(jù)(3D Model)，經(jīng)電腦分層離散處理后，把原來的三維數(shù)據(jù)表層二維平面數(shù)據(jù)，按特定的成型方法，通過逐點(diǎn)逐面將成型材料一層層加工，并堆積成型。

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.

快速成型技術(shù)是將一個(gè)實(shí)體的復(fù)雜的三維加工離散成一系列層片的加工，大大降低了加工難度，開辟了不用任何刀具而迅速制作各類零件的途徑，并為用常規(guī)方法不能或難以制造的模型或零件提供了一種新型的制造手段。南寧模型公司

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.

快速成型技術(shù)特點(diǎn)如下：

The characteristics of rapid prototyping technology are as follows:

1、改變了傳統(tǒng)模型的制造方式，用CAD模型直接驅(qū)動(dòng)實(shí)現(xiàn)設(shè)計(jì)與制造高度一體化，充分體現(xiàn)了設(shè)計(jì)評(píng)價(jià)制造的一體化思想，其直觀性和易改性為產(chǎn)品的*設(shè)計(jì)提供了優(yōu)良的設(shè)計(jì)環(huán)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、可以制造任意復(fù)雜形狀的三維實(shí)體模型，充分體現(xiàn)設(shè)計(jì)細(xì)節(jié)，尺寸和形狀精度大衛(wèi)提高，零件不需要進(jìn)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、成型過程不需要工裝模具的投入，既節(jié)省了費(fèi)用又縮短了制作周期。

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

4、成型全過程的快速性適合現(xiàn)代激烈的產(chǎn)品市場。

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