The concept of 3D printing first appeared in the mid-1990s, so it is easy to understand that 3D printing is a rapid prototyping device that uses photocuring and paper stacking technology. Its working principle is basically the same as ordinary printers, which are equipped with liquid or powder "printing materials" connected to the computer. Through the layers of "printing materials" stacked by the computer, the blueprint in the computer is ultimately transformed into physical objects, 3D printing technology.

　　Is 3D printing really disappearing after two fashions? In fact, 3D printing technology has gradually integrated into our lives, why do we say that? In fact, many people do not understand that many things around us already have the shadow of 3D printing. Simply put, the pen holders, lampshades, and other handicrafts we commonly use are all 3D printed, but there are also some car bumpers, some precision components of airplanes and ships that are 3D printing technology products.

　　3D printing has always been the pillar technology of future industry. Many people hold a skeptical attitude. In fact, with the progress of society, traditional manufacturing has become increasingly difficult to meet the needs of modern people. Since the beginning of the 21st century, gifts given to others on birthdays or holidays are not limited to beauty or practicality, but more attention should be paid to being unique and unique, or being customized by individuals. At this time, traditional material reduction manufacturing is very extensive. 3D printing technology can make up for the shortcomings of traditional manufacturing. With only the size and requirements provided by customers, 3D printing can meet your 100% accuracy and similarity requirements. Is it convenient?

　　What does 3D printing bring us? Generally speaking, 3D printing is convenient, fast, easy to produce, time-saving, and labor-saving. Therefore, in the near future, 3D printing will change people's lives, and future life must be high-end and convenient.
