快速成型技术又称快速原型制造技术，快速成型设备可以直接、快速、精确地把设计构想或设计方案通过模型建立、近似处理和切片处理等过程转变为实际的零件原型或者直接制造零件，为零件的原型制作和设计构想的校验等方面提供了一种低成本的实现手段，弥补了传统制造方法的不足。

Rapid prototyping technology is also known as rapid prototyping manufacturing technology. Rapid prototyping equipment can directly, quickly and accurately transform the design idea or design scheme into the actual part prototype or directly manufacture parts through the processes of model establishment, approximate processing and slicing processing. It provides an efficient and low-cost implementation means for the prototype production of parts and the verification of design idea, and makes up for the shortcomings of traditional manufacturing methods.

快速成型技术是基于离散/堆积成型原理，根据三维CAD模型，按一定厚度把CAD模型进行分层，将三维模型变成厚度很薄的二维平面模型。

Rapid prototyping technology is based on the principle of discrete / stacking forming. According to the 3D CAD model, the CAD model is layered according to a certain thickness, and the 3D model is changed into a 2D plane model with very thin thickness.

再将二维模型进行数据处理，加入加工参数，在数控系统控制下以平面加工方式连续加工出每个薄层，并使之粘结而成形。

Then the data of the two-dimensional model is processed, and the machining parameters are added. Under the control of the NC system, each thin layer is continuously machined by plane machining and bonded to form.

快速成型有很多工艺方法，所有的快速成型方法都是一层一层地制造零件，所不同的是每种方法所用的材料不同，粘结方式不同。典型的快速成型技术有光固化快速成型（SLA）、熔融沉积（FDM）、激光粉末烧结（SLS）和叠层轮廓（LOM）。

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 bonding methods. Typical rapid prototyping technologies include light curing rapid prototyping (SLA), melt deposition (FDM), laser powder sintering (SLS) and laminated profile (LOM).

与传统的处理方式相比，快速成型技术在速度性、集成化、适用性、可调整性和自动化等方面具有明显优势。比如：快速成型技术实现了完全的自动化成型，只需操作员输入相关的参数，在不需要过多干涉的情况下，就可以实现整个过程的自动运转。

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

随着快速成型技术的发展，其被广泛应用于模具制造过程中。该技术可以进行新产品的快速试制，制作周期仅为传统技术的1/4左右，可以有效提升模具制造的一次成功率。

With the development of rapid prototyping technology, it is widely used in mold manufacturing process. This technology can carry out rapid trial production of new products, and the production cycle is only about 1/4 of that of traditional technology, which can effectively improve the one-time success rate of mold manufacturing.
