在外觀及人機評價中的應用

Application in appearance and man-machine evaluation

新產品開發的設計階段，雖然可借助設計圖紙和計算機模擬，但并不能展現原型，往往難以做出正確和迅速的評價，設計師可以通過制作樣機模型達到檢驗的目的。傳統的模型制作中主要采用的是手工制作的方法，制作工序復雜，手工制作的樣機模型不僅工期長，而且很難達到外觀和結構設計要求的精確尺寸，因而其檢查外觀及人機設計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.

山東快速成型設備制作的高精度、高品質樣機與傳統的手工模型相比較可以更直觀地以實物的形式把設計師的創意反映出來，方便產品的外觀造型和人機特性評價。

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.

現在的快速成型加工得到的成型件都是單一顏色，顏色主要由材料決定，為了對產品色彩外觀進行評價，有時需要手工涂色，隨著彩色成型技術的發展，這方面的問題可以解決。人機評價主要包括成型件尺寸及操作宜人性，快速成型可以很好地滿足這方面的要求。

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.

在產品結構評價中的應用

Application in product structure evaluation

通過快速成型制成的樣機和實際產品一樣是可裝配的，所以它能直觀地反映出結構設計合理與否，安裝的難易程度，使結構工程師可以及早發現和解決問題。由于模具制造的費用一般很高，比較大的模具往往價值數十萬乃幾百萬，如果在模具開出后發現結構不合理或其他問題，其損失可想而知。而應用快速成型技術的樣機制作可以把問題解決在開出模具之前，大大提高了產品開發的效率。

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.

與反求工程結合

Combined with reverse engineering

反求工程(ReverseEngineering,RE)也稱逆向工程，就是用一定的測量手段對實物或模型進行測量，然后根據測量數據通過三維幾何建模方法重建實物的CAD數字模型，從而實現產品設計與制造過程。對于大多數產品來說，可以在通用的三維CAD軟件上設計出它們的三維模型，但是由于對某些因素，如對功能、工藝、外觀等的考慮，一些零件的形狀十分復雜，很難在CAD軟件上設計出它們的實體模型，在這種情況下，可以通過對模型測量和數據處理，獲得三維實體模型。

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.

作為一種新產品開發以及消化、吸收技術的重要手段，反求工程和快速成型技術可以勝任消化外來技術成果的要求。對于已存在的實體模型，可以先通過反求工程，獲取模型的三維實體，經過對三維模型處理后，使用快速成型技術，實現產品的快速復制，縮短了產品開發周期，大大提高產品的開發效率。

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.

快速成型技術可以大大縮短產品的開發周期，滿足產品的個性化、多樣化需求，在工業設計中得到廣泛應用。但由于該技術的制作精度、強度和耐久性還不能滿足工程實際的需要，加之設備的運行及制作成本高，一定程度上制約著RP技術的普遍推廣。您有什么疑惑或者需求就來我們網站http://www.ebook5.cn咨詢吧！

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.
