Dyeing 3D Printed Parts

Dyeing 3D printed parts involves immersing the printed part in a hot liquid dye solution, which allows the dye to penetrate the surface layer. Dyeing is particularly popular in materials such as nylon parts.

What is dyeing?

Dyeing in 3D printing is a method of adding color to a printed object in post-processing.

Dyeing is particularly effective with materials such as nylon that are commonly used in Selective Laser Sintering (SLS) and Multi Jet Fusion (MJF) parts.

The process involves immersing the printed part in a high-temperature dye solution, allowing the dye to penetrate the outer layers. Dyeing is a cost-effective way to give 3D printed parts a vibrant and consistent color.

The Advantages of Dyeing

1. Adds vibrant, consistent color to objects, making them visually appealing.

2. Cheaper than painting or using colored filaments.

3. Dyes penetrate the surface, so colors are less likely to chip or flake.

4. Suitable for painting challenging, complex geometries.

5. Maintains strength and flexibility of printed parts.

Dyeing Process

1. Preparation: Clean the printed parts to remove any dust or residues.

2. Heating the Dye Solution: Prepare a dye bath by heating water and dissolving the dye powder or liquid. The temperature and dye type depend on the material.

3. Dyeing: Submerge the parts into the dye solution. Stir occasionally to ensure even coloring. Duration varies based on the desired intensity of color.

4. Rinsing: Remove parts from the dye bath and rinse them in warm water to wash off any excess dye.

5. Drying: Let the parts dry completely. Usually, air drying is sufficient.

Quality Inspection Process

Check out the quality inspection process of dyed parts at 3DSPRO.

Visual Inspection
Check the surface for any imperfections, color consistency, and overall aesthetics.

Dimensional Measurement
Measure the X, Y, and Z dimensions to ensure the part has been dyed and has not changed in size.

Flatness/Warp Inspection
Verify if the part has warped or deformed during the dyeing process.

Foreign Object Debris (FOD) Inspection
Ensure there are no foreign particles or debris on the part.

Color-fastness Testing
Evaluate the durability of dyes by checking whether they fade or bleed under various conditions.

Mechanical Testing
Testing is performed to ensure that the dyeing process has not compromised the mechanical properties of the part.
