Silk: full cost overview
Silk PLA adds a polymer modifier that produces a high-gloss, satin-finish surface from a standard nozzle. No structural improvement over PLA — purely cosmetic — but priced similarly. Great for keychains, vases and any decorative part where finish matters more than strength.

How to print well in Silk
Silk PLA is PLA with a polymeric modifier that produces a satin / glossy surface straight off the nozzle — no polishing or extra finishing needed. Prints exactly like PLA: nozzle 200-215 °C (for basic Silk) or 220-230 °C (for Silk Triple / Multi-color), bed 50-60 °C, no chamber. Cooling: paradoxically lower than standard PLA (50-70% instead of 100%) — an aggressive fan dulls the shine. Thin layers (0.12-0.16 mm) accentuate the satin effect; thicker layers (0.2+ mm) come out more matte. Silk in colors like gold, silver, cobalt blue and wine red is most common for decorative parts — vases, sculptures, board-game pieces.
Typical cost in practice
Silk PLA in the US runs $25-34/kg (Hatchbox Silk, eSun ePLA-Silk) and $35-50/kg in premium variants like Silk Triple (3 colors on the same spool — gradient effect). For a decorative 30 g part, filament cost is $0.80-1.10; the gain is purely cosmetic, so it only pays off on parts where finish matters (decoration, gifts, cosplay). Don't use Silk for functional parts — mechanical properties are identical to standard PLA, with no structural advantage.
