1.3D printer, also called 3D printer (3DP), is a machine with cumulative manufacturing technology, namely rapid prototyping technology. It is a file based on digital model, which uses special adhesive materials such as wax, powdered metal or plastic, and prints adhesive material layers to make 3D objects. At present, three-dimensional printers are used to manufacture products. The technique of constructing objects by printing layer by layer. The principle of 3D printer is to input data and raw materials into 3D printer, and the machine will make products layer by layer according to the program.

2.3D printers can be used for:?

(1) industrial manufacturing: product concept design, prototype production, product review and functional verification; Make a mold prototype or directly print the mold and directly print the product. ?

(2) Cultural creativity and digital entertainment: artistic expression carriers with complex shapes and structures and special materials. Some characters and props are created by 3D printing, and the 3D printed violin is close to the level of handicraft. ?

(3) Aerospace, national defense and military industry: direct manufacturing of parts and mechanisms with complex shapes, fine dimensions and special performance; ?

(4) Biomedical treatment: artificial bones, teeth, hearing AIDS, artificial limbs, etc. ?

(5) Consumer goods: design and manufacture of jewelry, clothing, footwear, toys and creative DIY works;

Principle:

Put the data and raw materials into a 3D printer, and the machine will build products layer by layer according to the procedure. Printed products can be used immediately. Food can also be printed with a 3D printer. This is also the future development direction of 3D printers that most foodies care about.

Brand?

There are 3D printers in Le Cai, Pro 3D, Aurora, Hong Rui, Sanyiyi and Xi Rui in China.

There are many foreign brands such as Stratasys, WINBO, XYZprinting, MBot, MakerBot, wiiboox and so on.

At present, there are still many 3D printers, especially foreign manufacturers, many of which are assembled by DIY.
