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