What Powder Coating does for 3D printed parts
Powder Coating 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 Powder Coating matches your cosmetic, durability, or assembly requirements before you upload a file.
Powder coating involves applying a dry powder to the surface of as-printed parts to create a durable, high-quality finish. Powder coating uses an electrostatic method to adhere the powder to the part, which is then cured under heat or ultraviolet light to form a smooth, uniform coating. It provides a thicker, more resilient surface than traditional liquid paints and comes in a wide variety of colors and textures. (Powder coating offers excellent durability and resistance to chipping, scratching and fading, and it releases very few volatile organic compounds (VOCs), making it an environmentally friendly choice.)
Finishing is quoted with the print. Select Powder Coating 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 Powder Coating
Appearance
Powder Coating 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, Powder Coating may improve wear, corrosion resistance, grip, or light diffusion so the part survives handling and end use.
Ready-to-assemble parts
When Powder Coating 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 Powder Coating 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 Powder Coating
Pick SLA, SLS, MJF, SLM, FDM, DLP, or CNC where applicable, then add Powder Coating 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
Powder Coating 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 Powder Coating to your file, request a manual quotation.
Need Powder Coating 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.
