In recent years, the term 3D printing has changed from unfamiliar to familiar, gradually moving into people's life and work. However, there are still many people who do not know enough about 3D printing. 3D printing is not mysterious, it is just a new manufacturing and processing technology. 3D printing is a kind of rapid prototyping technology. It is a kind of rapid prototyping technology based on digital model (3D design file) file, using powder metal or plastic and other adhesive materials, through 3D printer, printing layer by layer to construct objects. Before we talk about 3D printing, let's take a look at 2D printing.

沒錯，我們生活中經常見到的噴墨打印機的打印方式就是2D打印，這種打印方式只能打印一個平面，而3D打印其實就是把這個平面一層層疊加起來，會變成實物，這也是為什么3D打印還有另一個名稱“增材制造技術”的原因。

Yes, the printing method of inkjet printers that we often see in our life is 2D printing. This printing method can only print one plane, while 3D printing actually superimposes this plane layer by layer and turns it into a real object. This is why 3D printing is also called "additive manufacturing technology".
         

那么為什么那么多人推崇這種制造方式呢？這就要說到人類自古以來的生產方式，從古時候的鑄造到工業革命時的機床加工，“等材制造”和“減材制造”一直是相對主流的加工方式，但這些加工方式有著廢料多，不，生產周期長等問題。而3D打印的出現改變了這一切，3D打印機無廢料，使用材料，生產周期短，上手門檻低以及一體成型等優點讓加工制造從工廠走向了家庭和學校，催生了個人設計者，激發了無限創意的可能。

So why do so many people admire this kind of manufacturing method? This is about the production mode of mankind since ancient times. From casting in ancient times to machine tool processing in the industrial revolution, "equal material manufacturing" and "reduced material manufacturing" have always been the relatively mainstream processing methods. However, these processing methods have many problems, such as waste, environmental protection, long production cycle and so on. The emergence of 3D printing has changed all this. The advantages of 3D printer, such as no waste, using environmentally friendly materials, short production cycle, low starting threshold and integrated molding, make the processing and manufacturing move from factory to home and school, give birth to personal designers, and stimulate the possibility of unlimited creativity.

于為何3D打印會有這些優點，這里就出現了另一個問題，3D打印到底是如何打印制件的？

As for why 3D printing has these advantages, there is another question: how does 3D printing print products?

，使用建模軟件建模，得到一個數據模型，然后將數據模型轉換為3D打印機能識別的格式并放入3D打印機，設置完成后3D打印機就會自動完成所有的打印工序，整個流程消耗的時間很短，上手難度也不高，使用方便的同時，打印過程中不會有廢料產生。

First of all, use the modeling software to build a data model, and then convert the data model into a format that can be recognized by the 3D printer and put it into the 3D printer. After the setting is completed, the 3D printer will automatically complete all the printing processes. The whole process consumes a short time, and it is not difficult to start. At the same time, it is convenient to use, and there will be no waste in the printing process.

得益于豐富的材料類型，3D打印快速成型技術的應用領域非常廣泛，目前涉及到的行業有工業、汽車、建筑、教育、醫療、影視以及航天航空。

Thanks to the rich types of materials, 3D printing rapid prototyping technology is widely used in industries such as industry, automobile, construction, education, medical treatment, film and television, and aerospace.
