In the process of making 3D printing models, some products with high appearance requirements often need to be spray painted and colored. Half of the spray paints have a matte appearance. If you need bright light, you need to have UV treatment. In addition to this, what are the advantages and disadvantages of UV highlight processing?

The UV high-gloss treatment will protect the surface, and the surface will have a smooth and transparent effect. Spray a layer of transparent oil on the surface of the sample and dry it with ultraviolet light. The product will be brighter and not easy to scratch.

The coating performance is excellent, and the coating has very high performance indicators in terms of hardness, wear resistance, acid and alkali resistance, salt spray resistance, gasoline resistance and other solvents; especially its paint film is full and gloss is particularly prominent;

The light curing process used in UV paint has no pollution when the paint is sprayed, and it is recognized as a green and environmentally friendly product;

Although 3D printed models have many advantages over UV, there are still some disadvantages. For example, UV coatings are sensitive to dust and therefore have strict requirements on the construction environment.

It is prone to bursting during the spraying process. It is not protected from the sun. It is easy to crack under the sun. It will turn yellow after a long time. Therefore, when the appearance of the product requires pure white, UV glazing is generally not used.
