For children's shoes that have never been exposed to 3D printing, I always feel that 3D printing is particularly far away. Today, teacher Haruko will unveil the mystery of 3D printing-introduce what 3D printing technology is in an easy-to-understand way. This paper mainly introduces the technical principle, process and application fields of 3D printing.

What is 3D printing technology?

In recent years, the term 3D printing has gradually changed from unfamiliar to familiar, and entered people's lives and work. However, there are still many children's shoes that don't know enough about 3D printing. 3D printing is not mysterious, it is just a new manufacturing technology. 3D printing is a rapid prototyping technology. It is a technology based on digital model (3D design file) file, which uses adhesive materials such as powder metal or plastic to print objects layer by layer through 3D printer.

If you don't understand this passage, you can imagine the production process in Tang Hua. The principle of 3D FDM printing technology is basically the same as the process of making Tang Hua.

Bondable material-hot syrup

Layer-by-layer printing-Pour syrup layer by layer (solidify layer by layer) on a (two-dimensional) plane, thus forming a (three-dimensional) object with height.

I believe you have some ideas about 3D printing. There are many kinds of 3D printing technologies, and the corresponding 3D printers and 3D printing materials are also different.
