Problems solved by technology

[0002] Since the aluminum alloy has been widely used, it has been widely used in electronic equipment industries such as computers and mobile phones due to its excellent characteristics. Its surface can be dyed to improve decoration, but in the existing anodic dyeing process, the anodic film falls off and the color fading process is extremely unstable, resulting in the disadvantage of low yield rate; in addition, direct dyeing of ordinary aluminum alloy anodic oxidation can achieve the appearance color, which cannot To make colorful patterns, aluminum alloy anodizing and ink masking technology can realize simple two-color pattern appearance. After aluminum alloy anodizing, cooperate with 3D printing to realize various color patterns, but the current pattern is a layer sprayed on the anodized film Organic coating on the surface; the pattern does not have the metallic texture of the anodized aluminum alloy film
