• Although PLA Silk Multi-Color is thoroughly dried and vacuum-sealed prior to shipping, variations in transport conditions may affect its moisture level. We strongly recommend drying it right after opening and storing it in a sealed container with desiccant or AMS. Repeat drying and moisture-proofing before each long-term storage period.

• Drying conditions: 55℃ for 8 hrs. Store in a dry environment after use. Dry before use if the material absorbs moisture. For more details please refer to: Filament drying instructions on WIKI.

• It’s strongly recommended to reduce the outer wall speed to 40 mm/s to optimize print quality.

• When printing with PLA Silk Dual Color filament, there is a small chance of filament rotation, potentially causing uneven color transitions. The A-series printers have a higher risk due to their special structure, so use of this filament with A-series printers is not recommended.

Gradient Effects

• The gradient effect depends on the amount of filament used, which can be influenced by adjusting sparse infill density, print quantity, or the filament spool starting point.

• Each color segment in Bambu PLA Silk Gradient spans approximately 20m (65g+).

• Using 40m (125g+) of filament guarantees at least one two-color transition.

• For four-color transitions (e.g., Bambu PLA Gradient – Dawn Radiance), using 80m (250g+) or more ensures the full effect.
