In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
As shown in fig. 1, the invention provides a coloring process based on a 3D printed nylon product, comprising the following steps:
a) and carrying out primary sand blasting treatment on the surface of the 3D printed nylon product through a sand blasting machine. On one hand, the first sand blasting treatment can remove the impurities remained on the 3D printed nylon product; on the other hand, the mechanical property of the surface of the coating can be improved, and the fatigue resistance can be improved, so that the adhesive force between the coating and the coating is increased, and the coating is beneficial to leveling and decoration. The manual work is replaced in the sand blasting machine operation, has improved work efficiency.
b) And (3) putting the 3D printed nylon product subjected to the first sand blasting treatment into polishing equipment for polishing operation so as to reduce the surface roughness of the nylon product and improve the dyed appearance. The polishing equipment is preferably a roller polishing machine, and the roller polishing machine also replaces manual operation, so that the working efficiency is further improved.
c) And (4) putting the polished 3D printed nylon product into a dip dyeing container for cooking and dyeing. The principle of the cooking dyeing operation is that the polished nylon product is immersed in liquid dye prepared in advance according to a certain proportion for cooking, and the dye molecules are physically adsorbed on the surface of the 3D printed nylon product, so that the purpose of changing the surface color of the original base material is achieved.
The dead angle problem that traditional spraying paint dyeing exists can be avoided in the boiling dyeing operation to the dyeing level of boiling dip-dyeing operation is more even, makes the color and luster uniformity of 3D printing nylon products after the dyeing better.
d) And taking out the 3D printed nylon product subjected to the cooking and dyeing operation, and airing for 1-2 hours to volatilize the dye liquid.

h) And starting the roller finishing machine to finish polishing the 3D printed nylon product. The 3D printing nylon product in the whole finishing process is required to be in full contact with the abrasive, water and polishing solution all the time.
In one embodiment, the diameter of the abrasive in step b) is 5-40 mm. Preferably, for 3D printed spectacle frame products, the abrasive is selected as spherical quartz particles with a diameter of 5 mm; for 3D printed cell phone shell products, the abrasive was selected as spherical quartz particles with a diameter of 20 mm.
In one embodiment, when the 3D printed nylon product in step b) is a bottle product, the bottle opening should be plugged with a plug and then placed in a roller finisher, so as to prevent the abrasive material from blocking the inner cavity of the product.
In one embodiment, the cooking and dyeing operation in step c) further comprises the steps of:
i) a certain amount of water is filled in the dip dyeing container and heated to 100-150 ℃.
j) The dye is mixed with warm water of 50-65 ℃, stirred evenly and poured into a dip dyeing container, and stirred again until being even.
k) And (3) putting the 3D printed nylon product into a dip dyeing container to finish dyeing, wherein the dyeing time is 0.5-10 h. Wherein, the larger the size and the wall thickness, the longer the dyeing time of the product.
In one embodiment, the dye of step i) is a weakly acidic liquid dye, a weakly acidic powder dye, a weakly basic liquid dye or a weakly basic powder dye. The weak acid dye has good washing fastness and milling fastness, but the level-dyeing property is general; the weak alkaline dye has high strength, bright color and good light fastness, but the light fastness and the color fastness to washing are poorer.
