The Rapid prototyping technology is based on the discrete/stacking principle. According to the 3D CAD model, the CAD model is layered according to a certain thickness, and the 3D model is transformed into a 2D plane model with very thin thickness. Then, the two-dimensional model is subjected to data processing, processing parameters are added, and each thin layer is continuously processed in a planar machining manner under the control of the CNC system, and bonded to form. There are many process methods for Rapid prototyping. All Rapid prototyping methods manufacture parts layer by layer. The difference is that each method uses different materials and different bonding methods. Typical Rapid prototyping technologies include photocurable Rapid prototyping (SLA), fused deposition (FDM), laser powder sintering (SLS), and laminated contour (LOM).

與傳統的處理方式相比，快速成型技術在速度性、集成化、適用性、可調整性和自動化等方面具有明顯優勢。比如：快速成型技術實現了完全的自動化成型，只需操作員輸入相關的參數，在不需要過多干涉的情況下，就可以實現整個過程的自動運轉。

Compared with traditional processing methods, Rapid prototyping technology has obvious advantages in speed, integration, applicability, adjustability and automation. For example, the Rapid prototyping technology has realized complete automatic molding. Only the operator needs to input relevant parameters, and the automatic operation of the whole process can be realized without too much interference.

更近幾年，快速成型技術得到了極大發展，其涉及的領域廣泛，應用行業眾多，主要集中在工業制造、建筑行業、醫學領域、藝術創造、考古研究、航空空間等領域。

In recent years, Rapid prototyping technology has been greatly developed. It involves a wide range of fields and has many applications, mainly in industrial manufacturing, construction industry, medical field, art creation, archaeological research, aerospace and other fields.

隨著快速成型技術的發展，其被廣泛應用于模具制造過程中。該技術可以進行新產品的快速試制，制作周期僅為傳統技術的1/4左右，可以有效提升模具制造的一次成功率。該技術是將模具的概念設計和生產工藝在CAD系統能進行綜合，利用計算機的模擬分析形成新型的模具設計制造系統，無需數控切削加工就可以制造出復雜的曲面等結構，有利于提高模具的制造柔性和質量。

With the development of Rapid prototyping technology, it is widely used in mold manufacturing process. This technology can be used for rapid trial production of new products, and the production cycle is only about 1/4 of traditional technology, which can effectively improve the one-time success rate of mold manufacturing. This technology integrates the conceptual design and production process of molds in a CAD system, utilizing computer simulation analysis to form a new type of mold design and manufacturing system. Without the need for CNC cutting, complex surfaces and other structures can be manufactured, which is conducive to improving the manufacturing flexibility and quality of molds.
