The printing method, process, and equipment used in 3D printing are similar to general pigment printing, with the main difference being the presence of microcapsule preparations or foaming agents in the printing ink. Therefore, during post press heat treatment, the pattern can quickly expand and bulge, forming a gorgeous 3D shape. There are various types of 3D printing, among which velvet printing and foam printing are very famous. The foaming technology and the three-dimensional pattern formed by the two are completely different. Under a microscope, the surface of the velvet print is piled with countless tiny soap bubble like spherical shapes, while the foam print appears honeycomb shaped. Therefore, velvet printed products have a unique velvet embroidery effect, while foam printed products have a vivid relief effect.
The printing ink used for velvet printing is composed of microcapsule preparations, adhesives, crosslinking agents, urea, coatings, thickeners, or water. Microcapsules are small hollow spheres with a particle size of about 50/um, and the capsule wall is composed of a copolymer of vinyl chloride and acrylonitrile (about 2:1), while the core contains low boiling organic solvents such as petroleum ether. Microcapsules are dispersed in emulsions such as poly (methyl methacrylate). The above-mentioned solvents rapidly vaporize at high temperatures, just like blowing soap bubbles, causing the volume of microcapsules to expand, and the enlarged microcapsules are squeezed together, forming an overlapping distribution like fluff. Therefore, this foaming method belongs to physical foaming.

Foam printing agent is a mixture of a foaming agent, appropriate film-forming agent, crosslinking agent, emulsion paste, and coloring agent, printed on fabric. After printing, during high-temperature treatment, the foaming agent undergoes thermal decomposition, producing a large amount of gas that causes the film-forming agent to slightly expand and form a film. The gas released by the foaming agent is contained in the film, forming innovative three-dimensional patterns. This type of foam printing belongs to chemical foaming.
The commonly used foaming agent is called azodicarbonamide. It is a light yellow crystalline powder that is insoluble in water. 64% of its decomposition products are solids and 36% are gases, which are composed of nitrogen, carbon monoxide, and carbon dioxide. Adding urea, depending on the amount of urea used, can lower the decomposition temperature of azodicarbonamide from around 200 degree C to around 180 degree C or even 150 degree C. Azobisisobutyronitrile is a white crystal that is insoluble in water and can also be used as a foaming agent. Its decomposition temperature is only 90-115 degree . However, its application is limited due to the presence of toxic tetramethylbutanedinitrile in its decomposition products. Foaming printing paste is generally composed of polystyrene, methyl methacrylate, butyl acrylate and acrylamide copolymer lotion, azodicarbonamide, urea, surfactant, thickening agent or water and colorant. Among them, polystyrene (or polyvinyl chloride) is a film-forming material, but it has poor adhesion to fabrics, so it needs to rely on the synergistic effect of acrylic copolymers.
Printed on a cold plate. According to the size of the pattern, nylon mesh sizes 11-14 are used for the sieve. After printing, dry with hot air at around 80 degree . The foaming conditions should be around 180-185 degree and loose. The disadvantage of foam printed fabrics is that they are prone to dirt and sticky, making them suitable for small area use.
