If you were asked to select a technology that can change the world today, what would you choose? Is it artificial intelligence, blockchain, AR and VR technology, or the obscure 3D printing technology? Compared to the popular science and technology of the previous few, 3D printing seems to be an ordinary meteor, flashing in an instant before disappearing. In practice, 3D printing technology is changing the world at a faster speed.

　　3D Printing Technology 3D Printers are a magical printer designed by a creator named Enrico Dini. It can not only "print" a intact building, but also print the shape of any desired item for astronauts in a spacecraft.

　　3D printer, also known as a machine for rapid prototyping technology, is a technology that uses digital model files as the foundation and uses adhesive materials such as special wax, powdered metal, or plastic to structure objects through layer by layer printing. Often used in mold manufacturing, industrial design, and other fields to manufacture models or for direct manufacturing of some products, it means that this technology is improving.

　　3D printing is not a novel technology. This idea originated in the late 19th century in the United States and was developed and promoted in the 1980s. 3D printing is usually completed using digital technology data printers. The production and sales of this type of printer have experienced significant growth since the 21st century, and its price is also decreasing year by year.
