Clear filament appearance depends on polymer, wall thickness, flow, voids and temperature. Thin walls look more transparent; fill lines and air gaps reduce clarity.
Choose material
- PLA for detail.
- PETG for toughness and moisture.
- PC for clarity and heat.
- Mineral-free grades for fewer inclusions.
Control print
Use uniform flow, stable temperature and enough wall thickness. Wet material and trapped air create cloudy defects.
Lighting test
- Same light.
- Final thickness.
- Background.
- Surface finish.
| Factor | PLA | PETG |
|---|---|---|
| Clarity | Good | Good |
| Toughness | Moderate | Higher |
| Moisture | Sensitive | Sensitive |
| Surface | Polishes well | Can scratch |
Common engineering mistakes
- Judging by a photo.
- Using thin test walls.
- Overheating.
- Wet filament.
- Polishing without measuring.
Buyer checklist
- What clarity is required?
- What thickness?
- Is the material dry?
- Is flow uniform?
- Was the final part tested?
