Part Dyeing Finish Option

The Art of Dyeing Parts

What is Part Dyeing?

Part dyeing is a post-processing step where printed nylon parts are immersed in a heated dye bath. Unlike paint or surface coatings, the dye bonds into the polymer itself, creating color that cannot flake or peel away. This gives parts a professional, finished appearance while retaining the mechanical strength of the base material.

How the Process Works

After bead blasting, parts are lowered into custom-built dye pots filled with water-based dye solutions maintained at controlled temperatures. These dyes are the same safe formulations widely used in the garment and textile industries, ensuring parts are both skin-safe and environmentally responsible. The controlled heating allows the dye to absorb evenly into the nylon, producing a consistent finish across complex geometries and internal surfaces. Once removed, the parts are rinsed and dried to lock in the color.

Benefits of Part Dyeing

• Durability – Dye penetrates into the nylon, so the color resists chipping or peeling.

• Clean, Professional Look – Black dyeing gives parts a uniform surface that hides powder residue and looks production-ready.

• UV Stability – Dyed parts show less fading or yellowing compared to untreated white nylon when exposed to sunlight.

• Skin Safe – Our dyes are safe for contact with skin, making dyed parts suitable for wearables and consumer applications.

• Cost Effective – Dyeing is a more affordable alternative to painting or coating, while offering better longevity.

Current Offering

We currently offer black dyeing only across our SLS materials. This provides the most durable and consistent finish for industrial and consumer parts. While color options may expand in the future, black dyeing remains the most reliable and cost-effective option for achieving a clean, professional look today.
