Q: How long is the color transition cycle?

{"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"The color transitions gradually over approximately 15 to 20 meters of filament. For very small or lightweight prints, you may only see one or two colors in the finished object."}]}]}

Q: How can I get more color changes on a small print?

{"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"To force more color transitions on small models, increase your infill percentage or add more outer perimeters in your slicer. This makes the printer consume more filament per layer, speeding up the visual color shift."}]}]}

Q: Does print speed affect the glossy finish?

{"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"Yes. Printing at slower speeds creates a shinier, more metallic appearance. For the best silk-like gloss, we recommend keeping your outer wall print speed between 40–60 mm/s, even though the filament supports up to 300 mm/s."}]}]}

Q: Is Silk Rainbow PLA as strong as standard PLA?

{"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"No. The elastomers added to create the glossy silk texture make the material slightly more brittle and reduce layer adhesion. It is specifically designed for decorative items and is not recommended for load-bearing functional parts."}]}]}

Q: Are supports difficult to remove from Silk PLA?

{"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"Support removal can be slightly more difficult because silk filaments tend to bond very tightly. We suggest increasing the support Z-distance in your slicer settings to ensure cleaner detachment without breaking delicate parts of your model."}]}]}
