在竞争日益激烈的市场经济中，模具制造业快速成型技术同样起到了重要作用，是制造技术群中的重要组成部分。它集中了计算机辅助设计和制造技术、激光技术和材料科学技术，在没有传统模具和夹具的情况下，快速制造出任意复杂形状而又具有一定功能的三维实体模型或零件，约新产品开发和模具制造、修复的费用。那么它具有哪些特点呢?

In the increasingly competitive market economy, Rapid prototyping technology in mold manufacturing industry also plays an important role and is an important part of the advanced manufacturing technology group. It focuses on Computer-aided design and manufacturing technology, laser technology and material science and technology. Without traditional molds and fixtures, it can rapidly manufacture 3D solid models or parts with arbitrary complex shapes and certain functions, which costs about Product development, mold manufacturing and repair. So what are its characteristics?

Rapid prototyping in Shandong is a technology of laser technology, numerical control technology, chemical industry, material engineering and other technologies, which has solved many problems in traditional processing and manufacturing. The widespread application of rapid prototyping technology in China has played a supporting role in the development of Chinese manufacturing enterprises, improved their ability to respond quickly to the market, improved their competitiveness, and made significant contributions to national economic growth.

1.复杂制造能力好，可完成传统方法难以完成的制造。产品复杂，研制时只有通过多轮的设计-原型机生产-试验-修改设计-原型机再生产-再试验过程，通过原型机重复试验才能及时发现问题并修正。但原型机的产量非常小，采用传统制造方式的时间长、成本高，造成研制的周期长，费用高。

1. Good complex manufacturing ability, capable of completing manufacturing that traditional methods are difficult to complete. The product is complex, and during development, problems can only be identified and corrected in a timely manner through multiple rounds of design prototype production testing modification prototype reproduction retesting process, and repeated prototype testing. However, the production capacity of the prototype is very small, and the traditional manufacturing method takes a long time and incurs high costs, resulting in a long development cycle and high costs.

2.小批量制造成本低、速度快，可显著降低研制风险、缩短研制时间。3D打印手板不需要传统制造方式的铸锭、制胚、模具、模锻等过程，可以快速、低成本地进行原型机生产，且整个生产过程数字化,可随时修正、随时制造，在短时间内进行大量的验证性试验，从而显著降低研制风险、缩短研制时间、降低研制费用。

2. Small batch manufacturing has low cost and fast speed, which can significantly reduce development risks and shorten development time. 3D printing hand boards do not require traditional manufacturing processes such as ingot casting, embryo making, molds, and forging. They can be quickly and low-cost for prototype production, and the entire production process is digitized, which can be corrected and manufactured at any time. A large number of validation tests can be conducted in a short time, significantly reducing development risks, shortening development time, and reducing development costs.

3.材料利用率高，可有效降低生产成本。传统的制造是“减材制造”，通过在原材料坯件上进行切削、挤压等操作，把多余的原料去除，加工出所需部件形状，加工过程中去除的原材料难以回收利用，原材料浪费严重。3D打印只在需要的地方添加原材料，材料利用率非常高，能够充分利用昂贵的原材料，显著降低的成本。

3. High material utilization rate can effectively reduce production costs. Traditional manufacturing is called "reduced material manufacturing", which involves cutting, squeezing, and other operations on raw material blanks to remove excess raw materials and produce the desired component shapes. The raw materials removed during the processing are difficult to recycle and waste seriously. 3D printing only adds raw materials where needed, and the material utilization rate is very high, which can fully utilize expensive raw materials and significantly reduce costs.

快速成型采用逐渐增加材料的方法(如凝固、焊接、胶结、烧结、聚合等)来形成所需的部件外型，由于RP技术在制造产品的过程中不会产生废弃物造成环境的污染，因此在当代讲究生态环境的今天，这也是一项绿色的制造技术。您有需要就来我们网站http://www.metferro.com咨询吧！

Rapid prototyping uses the method of gradually increasing materials (such as solidification, welding, cementation, sintering, polymerization, etc.) to form the required part shape. Since RP technology does not produce waste in the process of manufacturing products and cause environmental pollution, it is also a green manufacturing technology in today's ecological environment.
