What Anodizing does for 3D printed parts
Anodizing is one of the 3D Plus hardware finishing services on AIHFABS. It is applied after printing so the part leaves production closer to a usable product—not only a raw build. Use this page to decide whether Anodizing matches your cosmetic, durability, or assembly requirements before you upload a file.
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.
Finishing is quoted with the print. Select Anodizing in checkout, review price and lead time, and keep printing plus post-processing in one order instead of coordinating a second shop.
Why teams specify Anodizing
Appearance
Anodizing can hide layer lines, even out color, or create a more uniform surface for display models, consumer housings, and review samples.
Performance
Depending on the process, Anodizing may improve wear, corrosion resistance, grip, or light diffusion so the part survives handling and end use.
Ready-to-assemble parts
When Anodizing is combined with printing, you receive parts that are closer to install-ready, reducing secondary work in your own workshop.
How to order this finish
Ordering Anodizing follows the same 3D Plus software flow as a standard print. You do not need a separate finishing RFQ for catalog options.
-
Upload the CAD file
Use STL, STEP, or another supported format. The quoter checks volume and geometry so finishing can be priced against the actual part.
-
Choose print process, material, and Anodizing
Pick SLA, SLS, MJF, SLM, FDM, DLP, or CNC where applicable, then add Anodizing and any other 3D Plus hardware options the part needs.
-
Compare price, lead time, and checkout
Review supplier options, confirm quantity, and place the order. Printing and finishing stay on one timeline and one invoice.
Compatible processes and design notes
Anodizing is typically applied to plastics or metals produced with industrial 3D printing. Compatibility depends on material, wall thickness, and whether the surface can be reached by spray, media, chemistry, or tooling. Deep recesses, thin walls, and optical faces may need design review. If the automatic quote cannot apply Anodizing to your file, request a manual quotation.
Need Anodizing on a batch, a mixed-material assembly, or a part that also requires tapping or painting? Keep those options in the same quote so lead time includes the full stack of operations.
