What Spray Painting does for 3D printed parts
Spray Painting 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 Spray Painting matches your cosmetic, durability, or assembly requirements before you upload a file.
Spray painting in 3D printing is used to enhance the aesthetic and qualities of 3D printed part. It applies a fine mist of paint using a spray gun or aerosol can. Spray painting provides a uniform and smooth finish and a wide range of color options based on Pantone color. Spray painting helps hide layer lines and minor imperfections efficiently and add protective layers.
Finishing is quoted with the print. Select Spray Painting 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 Spray Painting
Appearance
Spray Painting 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, Spray Painting may improve wear, corrosion resistance, grip, or light diffusion so the part survives handling and end use.
Ready-to-assemble parts
When Spray Painting 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 Spray Painting 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 Spray Painting
Pick SLA, SLS, MJF, SLM, FDM, DLP, or CNC where applicable, then add Spray Painting 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
Spray Painting 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 Spray Painting to your file, request a manual quotation.
Need Spray Painting 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.
