Anodizing

Anodizing in 3D printing is an electrochemical process that enhances the surface properties of metal parts, particularly aluminum. Anodized aluminum has improved wear resistance and electrical insulation and can add vibrant colors through dyes. Types of anodizing include standard anodizing, which offers a colorful and protective layer, and hard anodizing(, also known as Type III anodizing), which produces a thicker, more robust oxide layer.
