Improving the application level of RP technology is an important aspect to promote the development of RP technology. At present, rapid prototyping technology has been widely used in industrial modeling, machinery manufacturing, aerospace, military, architecture, film and television, home appliances, light industry, medicine, archaeology, culture and art, sculpture, jewelry and other fields. With the development of technology itself, its application field will continue to expand. The practical application of RP technology mainly focuses on the following aspects:

(1)快速成型技术在新产品建模设计中的应用，为工业产品的设计者和建立了一种新的产品开发模型。RP技术的应用可以快速、直接、准确地将设计思想转化为具有一定功能的物理模型(样本)，不仅缩短了开发周期，还降低了开发成本，使企业在激烈的市场竞争中占有优势。

(1) The application of rapid prototyping technology in new product modeling and design establishes a new product development model for the designers and developers of industrial products. The application of RP technology can quickly, directly and accurately transform the design idea into a physical model (sample) with certain functions, which not only shortens the development cycle, but also reduces the development cost, so that the enterprise has an advantage in the fierce market competition.

(2)在机械制造领域的应用由于RP技术的特点，在机械制造领域得到了广泛的应用，多用于制造单件或小批量金属零件。有些特殊复杂零件，由于只生产单件，或50件以下的小批量，一般可以直接采用RP技术成型，成本低，周期短。

(2) Application in the field of mechanical manufacturing due to the characteristics of RP technology, it has been widely used in the field of mechanical manufacturing, mostly used to manufacture single or small batch of metal parts. Some special and complex parts can be directly formed by RP technology because they only produce single parts or small batches of less than 50 pieces, with low cost and short cycle.

传统模具生产时间长，成本高。快速成型技术与传统模具制造技术相结合，可以大大缩短模具制造的开发周期，提高生产效率，是解决模具设计制造薄弱环节的有效途径。快速成型技术在模具制造中的应用可以分为直接成型和间接成型,直接成型是指利用RP技术直接堆放生产模具,间接成型是个快速成型零件的生产,然后是部分复制所需的模具。

Traditional mold production time is long and cost is high. The combination of rapid prototyping technology and traditional mold manufacturing technology can greatly shorten the development cycle of mold manufacturing and improve production efficiency, which is an effective way to solve the weak link of mold design and manufacturing. The application of rapid prototyping technology in mold manufacturing can be divided into direct molding and indirect molding. Direct molding refers to the use of RP technology to directly stack production mold. Indirect molding is the production of the first rapid prototyping part, and then part of the mold required for replication.

近年来，关于RP技术在医学领域的应用研究较多。在医学图像数据的基础上，利用RP技术制作人体器官模型，具有很大的手术应用价值。

In recent years, there are many researches on the application of RP technology in the field of medicine. On the basis of medical image data, RP technology is used to make human organ model, which has great application value in surgery.

在文化艺术领域，快速原型制造技术主要用于艺术创作、文物复制、数字雕塑等。

In the field of culture and art, rapid prototype manufacturing technology is mainly used in art creation, cultural relics reproduction, digital sculpture, etc.

在航空航天领域，气动地面模拟实验(即风洞实验)是航天飞机系统(即航天飞机)设计中必不可少的重要环节。该模型具有形状复杂、精度要求高、流线型等特点。采用RP技术。根据CAD模型，实体模型由RP装置自动完成，可以很好地保证模型的质量。

In the field of Aeronautics and Astronautics, aerodynamic ground simulation experiment (wind tunnel experiment) is an essential part in the design of advanced space shuttle system (space shuttle). The model has the characteristics of complex shape, high precision and streamline. RP technology is adopted. According to the CAD model, the solid model is automatically completed by RP device, which can guarantee the quality of the model.

(7)在家电行业的应用目前，快速成型系统已经在国内家电行业得到了很大程度的推广和应用，使得许多家电企业在国内市场上处于地位。一些公司相继采用快速成型系统开发新产品，取得了良好的效果。快速成型技术被广泛应用。相信随着快速成型技术的不断成熟和完善，将会在越来越多的领域得到推广和应用。

(7) At present, the application of rapid prototyping system in home appliance industry has been promoted and applied to a large extent, which makes many home appliance enterprises in the leading position in the domestic market. Some companies have used rapid prototyping system to develop new products, and achieved good results. Rapid prototyping technology is widely used. It is believed that with the continuous maturity and improvement of rapid prototyping technology, it will be popularized and applied in more and more fields.
