Metallic and marble-effect filament finishing requires controlled printing, careful sanding and compatible coating. Strong sanding can erase the visual effect and change dimensions.
Print preparation
- Stable flow.
- Consistent temperature.
- Nozzle condition.
- Clean surface.
Finishing
Sand progressively, clean between steps and test coating on a sample. Preserve critical dimensions.
Validation
- Appearance.
- Texture.
- Dimensions.
| Step | Risk | Control |
|---|---|---|
| Coarse sanding | Detail loss | Pressure |
| Polishing | Heat | Speed |
| Coating | Colour shift | Sample |
| Cleaning | Scratches | Tool |
Common engineering mistakes
- Sanding too hard.
- Skipping grits.
- Overheating.
- Coating without test.
- Ignoring dimensions.
Buyer checklist
- Is the print stable?
- Are grits progressive?
- Is the finish tested?
- Are dimensions preserved?
- Is lighting controlled?
