Bottom line: silk filament produces its glossy finish through pigment orientation combined with a smooth printed surface. Layer height, wall speed, temperature and flow determine how much light is reflected rather than scattered. A rough surface makes the same filament look matte.
What drives the effect
| Factor | Effect |
|---|---|
| Surface roughness | scatters light, reduces gloss |
| Layer height | larger layers leave visible ridges |
| Wall speed | faster walls increase vibration marks |
| Temperature | affects flow and layer fusion |
| Pigment orientation | changes reflection direction |
Practical settings
- Reduce layer height to about 0.1–0.2 mm on a 0.4 mm nozzle.
- Slow the outer wall.
- Use the mid-to-upper temperature range.
- Use moderate cooling.
- Keep 2–3 continuous walls.
Costly mistakes
- Prioritising speed and leaving visible layer lines.
- Printing too cold for stable flow.
- Over-cooling and weakening layer bonding.
- Confusing gloss with strength.
- Ignoring moisture blisters on the surface.
Buyer / engineer checklist
- Is layer height suitable?
- Is the wall speed slow enough?
- Is the temperature stable?
- Is cooling balanced?
- Is the filament dry?
