E-coating dunks a conductive machined part in a charged bath so the film builds to a uniform thickness — including pockets a spray gun misses. Typical on steel and aluminum CNC parts that need corrosion resistance before powder or paint.
Electrocoating 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 Electrocoating matches color, wear, or assembly needs before you upload a file.

Finishing is quoted with the machine work. Select Electrocoating 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.
Electrocoating can hide cutter marks, even out color, or leave a uniform skin on housings, brackets, and review samples.
Depending on the process, Electrocoating may improve wear, corrosion resistance, or grip so the machined part survives handling and end use.
When Electrocoating sits on the same traveler as milling or turning, the part arrives closer to install-ready — color, coat, or threads already on it.
Ordering Electrocoating uses the same upload as a standard CNC quote. You do not need a separate finishing RFQ for catalog options.
Use STEP, STP, or another supported format. The quoter reads the stock so finishing can be priced against the actual blank.
Pick milling, turning, or another CNC route, then add Electrocoating and any other finishing the part needs.
Review options, confirm quantity, and place the order. Machining and finishing stay on one timeline and one invoice.
Electrocoating 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 Electrocoating, request a manual quotation.
Need Electrocoating 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.

Electrocoating, or e-coating, is a method used to apply a smooth, even layer of paint or coating to 3D printed parts. The process involves dipping the parts into a water-based coating solution and then running an electric current through them. The current causes the paint particles to adhere uniform

Electrocoating 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 Electrocoating when the selected material can accept it.
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.
Put the Pantone or RAL code in the quote notes, or upload a swatch. Electrocoating covers the reachable exterior; deep recesses and contact faces may stay uncoated unless you ask for full coverage.
Upload the CAD file, choose a print process and material, then turn on Electrocoating. 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.
