模型制作中的快速成型技術，又稱快速制樣或實體自由形式制造，是一種用材料逐層對基礎制件的制作方法，是集CAD、數控技術、精密機械、激光技術和材料科學與工程等新技術而發展起來的產品設計開發技術。

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, numerical control technology, precision machinery, laser technology and material science and engineering.

山東快速成型是一種離散、堆積成型的加工技術，其目標是將計算機三維CAD模型快速地轉變為具體物質構成的三維實體模型。快速成型的基本過程是將計算機輔助設計的產品的立體數據(3DModel)，經電腦分層離散處理后，把原來的三維數據表層二維平面數據，按特定的成型方法，通過逐點逐面將成型材料一層層加工，并堆積成型。

Rapid prototyping in Shandong Province is a discrete and stacking processing technology, whose goal is to quickly transform the computer 3D CAD model into a 3D solid model composed of concrete materials. The basic process of Rapid prototyping is to process the three-dimensional data (3DModel) of Computer-aided design products by layers and discrete processing by computer, and then process the original three-dimensional data surface two-dimensional plane data according to the specific molding method, and process the molding materials layer by layer, point by point, surface by surface, and stack them for molding.

其特點如下：

Its characteristics are as follows:

1、改變了傳統模型的制造方式，用CAD模型直接驅動實現設計與制造高度一體化，充分體現了設計評價制造的一體化思想，其直觀性和易改性為產品的設計提供了優良的設計環境。

1. It has changed the traditional manufacturing method of models and directly driven by CAD models to achieve a high degree of integration between design and manufacturing, fully reflecting the integrated concept of design evaluation and manufacturing. Its intuitive and easy to modify nature provides an excellent design environment for product design.

2、可以制造任意復雜形狀的三維實體模型，充分體現設計細節，尺寸和形狀精度大衛提高，零件不需要進一步加工。

2. It can manufacture three-dimensional solid models of any complex shape, fully reflecting design details, improving dimensional and shape accuracy, and eliminating the need for further processing of parts.

3、成型過程不需要工裝模具的投入，既節省了費用又縮短了制作周期。

3. The forming process does not require the investment of tooling and molds, which not only saves costs but also shortens the production cycle.

4、成型全過程的快速性適合現代激烈的產品市場。

4. The rapidity of the entire molding process is suitable for the fierce modern product market.

快速成型技術是將一個實體的復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。更多相關事項就來我們的網站http://www.metferro.com咨詢吧！
