The difference between anodizing and painting in the surface finish of prototype processing

Anodizing and painting are common surface finish processes when making prototype models. Although anodizing and painting both make the surface of the prototype color, there are still differences between them, which are mainly reflected in the following three aspects:
1.For different materials, painting can be applied to many materials for prototypes, such as metal, plastic and resin, and anodizing is a surface finish process that only aluminum alloy prototypes have.
2.The color persistence is different. Because the painting only painting a layer of paint on the surface of the prototype, it will fall off over time, and the anodizing is to soak the aluminum alloy prototype in the potion to form an oxide film on the surface.Because the alumina produced by anodizing is a stable substance, it is difficult to react with oxidation in the air, so the color of the surface is relatively stable and not easy to fall off.
3.The effect is different. The anodizing color has a metallic texture. If you use painting, you will not be able to adjust that effect anyway.
