3D打印不同于傳統(tǒng)的數(shù)控加工。這兩種技術(shù)都是處理手牌的過(guò)程。3D打印手板被稱為加法制造，數(shù)控加工則是減量化制造。3D打印和CNC有很大的區(qū)別。

　　3D printing is different from traditional NC machining. Both techniques are the process of handling cards. 3D printing hand board is called additive manufacturing, while numerical control machining is reductive manufacturing. There is a big difference between 3D printing and CNC.

　　在工藝上，3D打印增材制造是一層一層建造的，就像蓋房子一樣，一磚一瓦。而數(shù)控還原材料的制造就像一塊剛出土的鉆石，雕刻家需要精雕細(xì)琢，慢慢地雕刻出來(lái)作為模型的裝飾品。所以在3D打印中，除了必要的支撐材料外，剩下的就是用來(lái)打印模型的材料，而3D打印并不存在結(jié)構(gòu)復(fù)雜的模型加工成本更高的情況。

　　In terms of technology, 3D printing additive manufacturing is built layer by layer, just like building a house, brick by brick. The manufacture of CNC reduction material is like a newly unearthed diamond. The sculptor needs to carve it carefully and slowly as the decoration of the model. So in 3D printing, in addition to the necessary supporting materials, the rest is the materials used to print the model, while 3D printing does not have a higher processing cost of the model with complex structure.

　　3D打印在打印復(fù)雜的形狀和不規(guī)則的結(jié)構(gòu)，如曲線和中空結(jié)構(gòu)等方面具有更多的優(yōu)勢(shì)。，3D打印可以加工傳統(tǒng)方法難以加工的零件。在過(guò)去，傳統(tǒng)的制造方法是一片空白，切割出不需要的區(qū)域，進(jìn)行多維加工，或者使用模具，將金屬和塑料熔鑄成這樣的零件，這對(duì)于加工復(fù)雜的零件是非常困難的。3D打印技術(shù)對(duì)于復(fù)雜零件具有很大的優(yōu)勢(shì)。它可以打印非常復(fù)雜的東西。

　　3D printing has more advantages in printing complex shapes and irregular structures, such as curves and hollow structures. First of all, 3D printing can process parts that are difficult to be processed by traditional methods. In the past, the traditional manufacturing method is a blank. It is very difficult to process complex parts by cutting out unnecessary areas, multi-dimensional processing, or using mold to melt metal and plastic into such parts. 3D printing technology has great advantages for complex parts. It can print very complex things.

　　3D打印實(shí)際上是關(guān)于快速原型的。如今，3D打印在建筑設(shè)計(jì)、醫(yī)療輔助、工業(yè)模型、復(fù)雜結(jié)構(gòu)、零部件、動(dòng)畫模型等領(lǐng)域都有一定程度的應(yīng)用。特別是在使用重型和精密機(jī)械的行業(yè)，如飛機(jī)、核能和火電等，3D打印技術(shù)“打印”出的產(chǎn)品自然無(wú)縫連接，結(jié)構(gòu)之間的穩(wěn)定性和連接強(qiáng)度比傳統(tǒng)方法大得多。

　　3D printing is really about rapid prototyping. Today, 3D printing has a certain degree of application in architectural design, medical assistance, industrial models, complex structures, components, animation models and other fields. Especially in the industries using heavy and high-end precision machinery, such as aircraft, nuclear power and thermal power, the products printed by 3D printing technology are naturally and seamlessly connected, and the stability and connection strength between structures are much greater than that of traditional methods.

　　與其他快速成型技術(shù)相比，3D打印技術(shù)具有以下優(yōu)點(diǎn):2. 產(chǎn)品多樣化不會(huì)增加成本;3.零時(shí)間交付;4. 無(wú)限的設(shè)計(jì)空間;5. Zero-skill制造;6、無(wú)空間，便攜式制造;7. 材料的無(wú)限組合;8. 準(zhǔn)確的物理繁殖。

　　Compared with other rapid prototyping technologies, 3D printing technology has the following advantages: 2. Product diversification will not increase costs; 3. Zero time delivery; 4. Unlimited design space; 5. Zero skill manufacturing; 6. No space, portable manufacturing; 7. Infinite combination of materials; 8. Accurate physical reproduction.
