在外观及人机评价中的应用

Application in appearance and man-machine evaluation

新产品开发的设计阶段，虽然可借助设计图纸和计算机模拟，但并不能展现原型，往往难以做出正确和迅速的评价，设计师可以通过制作样机模型达到检验的目的。传统的模型制作中主要采用的是手工制作的方法，制作工序复杂，手工制作的样机模型不仅工期长，而且很难达到外观和结构设计要求的精确尺寸，因而其检查外观及人机设计合理性的功能大打折扣。

In the design stage of new product development, although the design drawings and computer simulation can be used, the prototype cannot be displayed, and it is often difficult to make correct and rapid evaluation. The designer can achieve the purpose of inspection by making prototype models. The traditional model production mainly adopts the hand-made method, and the production process is complex. The hand-made prototype model not only has a long construction period, but also is difficult to achieve the precise size required by the appearance and structure design, so its function of checking the rationality of the appearance and human-machine design is greatly discounted.

山东快速成型设备制作的高精度、高品质样机与传统的手工模型相比较可以更直观地以实物的形式把设计师的创意反映出来，方便产品的外观造型和人机特性评价。

Compared with the traditional manual model, the high-precision and high-quality prototype made by Shandong rapid prototyping equipment can more intuitively reflect the designer's creativity in the form of physical objects, facilitating the product's appearance modeling and human-machine characteristics evaluation.

现在的快速成型加工得到的成型件都是单一颜色，颜色主要由材料决定，为了对产品色彩外观进行评价，有时需要手工涂色，随着彩色成型技术的发展，这方面的问题可以解决。人机评价主要包括成型件尺寸及操作宜人性，快速成型可以很好地满足这方面的要求。

The molding parts obtained by the current rapid prototyping process are all single color, and the color is mainly determined by the material. In order to evaluate the color appearance of the product, it is sometimes necessary to paint manually. With the development of color molding technology, this problem can be solved. Human-machine evaluation mainly includes the size of molded parts and the ease of operation, and rapid prototyping can well meet this requirement.

在产品结构评价中的应用

Application in product structure evaluation

通过快速成型制成的样机和实际产品一样是可装配的，所以它能直观地反映出结构设计合理与否，安装的难易程度，使结构工程师可以及早发现和解决问题。由于模具制造的费用一般很高，比较大的模具往往价值数十万乃几百万，如果在模具开出后发现结构不合理或其他问题，其损失可想而知。而应用快速成型技术的样机制作可以把问题解决在开出模具之前，大大提高了产品开发的效率。

The prototype made by rapid prototyping can be assembled as the actual product, so it can directly reflect whether the structural design is reasonable or not, and the ease of installation, so that the structural engineer can find and solve problems as soon as possible. Due to the high cost of mold manufacturing, relatively large molds are often worth hundreds of thousands or even millions. If the structure is unreasonable or other problems are found after the mold is opened, the loss can be imagined. The prototype manufacturing using rapid prototyping technology can solve the problem before opening the mold, which greatly improves the efficiency of product development.

与反求工程结合

Combined with reverse engineering

反求工程(ReverseEngineering,RE)也称逆向工程，就是用一定的测量手段对实物或模型进行测量，然后根据测量数据通过三维几何建模方法重建实物的CAD数字模型，从而实现产品设计与制造过程。对于大多数产品来说，可以在通用的三维CAD软件上设计出它们的三维模型，但是由于对某些因素，如对功能、工艺、外观等的考虑，一些零件的形状十分复杂，很难在CAD软件上设计出它们的实体模型，在这种情况下，可以通过对模型测量和数据处理，获得三维实体模型。

Reverse Engineering (RE), also known as reverse engineering, is to measure the real object or model with certain measuring means, and then reconstruct the CAD digital model of the real object through 3D geometric modeling method according to the measured data, thus realizing the product design and manufacturing process. For most products, their 3D models can be designed on the general 3D CAD software. However, due to the consideration of some factors, such as function, technology, appearance, etc., the shape of some parts is very complex, and it is difficult to design their solid models on the CAD software. In this case, the 3D solid models can be obtained through model measurement and data processing.

作为一种新产品开发以及消化、吸收技术的重要手段，反求工程和快速成型技术可以胜任消化外来技术成果的要求。对于已存在的实体模型，可以先通过反求工程，获取模型的三维实体，经过对三维模型处理后，使用快速成型技术，实现产品的快速复制，缩短了产品开发周期，大大提高产品的开发效率。

As an important means of developing new products and digesting and absorbing advanced technologies, reverse engineering and rapid prototyping technology can meet the requirements of digesting foreign technological achievements. For the existing solid model, you can first obtain the 3D entity of the model through reverse engineering. After processing the 3D model, you can use rapid prototyping technology to realize the rapid replication of the product, shorten the product development cycle, and greatly improve the product development efficiency.

快速成型技术可以大大缩短产品的开发周期，满足产品的个性化、多样化需求，在工业设计中得到广泛应用。但由于该技术的制作精度、强度和耐久性还不能满足工程实际的需要，加之设备的运行及制作成本高，一定程度上制约着RP技术的普遍推广。您有什么疑惑或者需求就来我们网站http://www.metferro.com咨询吧！

Rapid prototyping technology can greatly shorten the product development cycle, meet the personalized and diversified needs of products, and is widely used in industrial design. However, the manufacturing accuracy, strength and durability of this technology can not meet the actual needs of the project, and the high cost of equipment operation and manufacturing, to some extent, restricts the general promotion of RP technology.
