Dual-Color Filament Test – Free 3D STL Model

Free STL model designed to test the effect of dual-color filaments in 3D prints.

Dual-color filaments contain two colors in the same filament, so the visible color changes depending on the orientation of the part and the light.

This model has faceted surfaces that help highlight the color-shifting effect of the filament.

⚙ How to use it

1. Download the STL file.
2. Open it in your slicer (Cura, OrcaSlicer, PrusaSlicer, etc.).
3. Select a dual-color filament.
4. Print the model normally.
5. Observe how the color changes depending on the viewing angle of the part.

💡 Recommendation

For the best visual effect:

• Use dual-color or PLA Silk Dual Color filaments.
• Print with 0.2 mm layers or less.
• Use contrasting colors.
