Background

The 3D printing is also called three-dimensional printing or stereo printing in english, which is called "three-dimensional printing" for short 3 DP. 3D printing technology is an emerging manufacturing technology employing additive manufacturing, the advent of which has subverted the technological paradigm of subtractive manufacturing in the traditional manufacturing industry for a long time. The 3D printing can directly print out parts with complex shapes by computer graphics data, has the advantages of low manufacturing cost and short production period, receives more and more extensive attention, and now covers the fields of aerospace, industrial design, automobiles, medical treatment, jewelry design, textiles and the like.

With the development of textile science and technology and the improvement of the economic level of people, the textile breaks through the original scope of heat preservation and beautification and is gradually going to functionalization and intellectualization. The appearance of the 3D printing technology brings new opportunities to the textile field, and the intellectualization, simplification and innovativeness of the textile printing process become new features. At present, the application of 3D printing technology in the textile field mainly includes 3D printing of clothing (one shot forming), 3D printing of shoes, 3D printing of decorations and the like of clothing. For the aspect of 3D printing fabric, research is less, and needs to be further improved.
