Spray Painting

Spray painting on CNC work hides cutter marks and matches a Pantone after a blast or primer. A gun lays an even film on housings and brackets. Color sits on the same job as the milling, not a second vendor.

What Spray Painting does after CNC machining

Spray Painting is a CNC finishing step on AIHFABS. It runs after milling or turning so the blank leaves closer to a usable part — not only a machine finish. Use this page to decide whether Spray Painting matches color, wear, or assembly needs before you upload a file.

Spray painting on CNC work hides cutter marks and matches a Pantone after a blast or primer. A gun lays an even film on housings and brackets. Color sits on the same job as the milling, not a second vendor.

Finishing is quoted with the machine work. Select Spray Painting in checkout, review price and lead time, and keep machining plus post-processing on one order instead of sending a raw blank to a second shop.

Why teams specify Spray Painting on CNC parts

Appearance

Spray Painting can hide cutter marks, even out color, or leave a uniform skin on housings, brackets, and review samples.

Performance

Depending on the process, Spray Painting may improve wear, corrosion resistance, or grip so the machined part survives handling and end use.

Ready-to-assemble blanks

When Spray Painting sits on the same traveler as milling or turning, the part arrives closer to install-ready — color, coat, or threads already on it.

How to order this CNC finish

Ordering Spray Painting uses the same upload as a standard CNC quote. You do not need a separate finishing RFQ for catalog options.

  1. Upload the CAD file

    Use STEP, STP, or another supported format. The quoter reads the stock so finishing can be priced against the actual blank.

  2. Choose CNC process, material, and Spray Painting

    Pick milling, turning, or another CNC route, then add Spray Painting and any other finishing the part needs.

  3. Compare price, lead time, and checkout

    Review options, confirm quantity, and place the order. Machining and finishing stay on one timeline and one invoice.

Compatible stock and design notes

Spray Painting is typically applied to metals — and some plastics — after CNC machining. Compatibility depends on alloy, wall thickness, and whether the surface can be reached by bath, media, or a tap. Deep pockets, thin walls, and datum faces may need a review. If the automatic quote cannot apply Spray Painting, request a manual quotation.

Need Spray Painting on a batch, a mixed set, or a part that also needs tapping or paint? Keep those options in the same quote so lead time includes the full stack.

Spray Painting questions

Answers that apply to Spray Painting on AIHFABS 3D Plus hardware — materials, size change, and how to order it with the print.

What is Spray Painting on a 3D printed part?

Spray painting on CNC work hides cutter marks and matches a Pantone after a blast or primer. A gun lays an even film on housings and brackets. Color sits on the same job as the milling, not a second vendor.

Which printed materials can take Spray Painting?

Spray Painting is a color or optical finish. SLS and MJF nylon take dye; resins take paint, primer, frosting, and clear coats; aluminum and other metals take anodizing, plating, or e-coat. The quoter only offers Spray Painting when the selected material can accept it.

Does Spray Painting change dimensions or hide layer lines?

Paint, plating, and e-coat add a thin film. Dye soaks into nylon with little build-up. Frosting and clear coats change how light hits the surface more than the CAD size. Call out fits and optical faces in the quote notes so they can be masked.

How do I specify color for Spray Painting?

Put the Pantone or RAL code in the quote notes, or upload a swatch. Spray Painting covers the reachable exterior; deep recesses and contact faces may stay uncoated unless you ask for full coverage.

How do I add Spray Painting to a quote?

Upload the CAD file, choose a print process and material, then turn on Spray Painting. Price and lead time update on the same order. If the automatic quote cannot apply it, request a manual quotation and note fits or color codes.
