KINGROON Rainbow Silk PLA Filament – 1.75 mm, 2.2 lb (1 kg)

Bring flowing color transitions and a glossy, silk-style finish to your next 3D-printing project. KINGROON rainbow silk PLA filament changes color along the spool, creating multicolor effects in decorative models, display pieces, and creative projects without manually swapping between single-color spools.

Color that unfolds as you print

• Rainbow gradient: Alternating color segments create transitions as the filament feeds through your printer.
• Silk-style finish: Designed to produce a smooth, glossy appearance.
• 1.75 mm filament: For compatible filament-based 3D printers that support PLA.
• 2.2 lb (1 kg) per spool: Net filament weight, excluding the spool.
• Seven styles: Choose from the existing Color A through Color G options.

Recommended starting settings

• Nozzle temperature: 383–446°F (195–230°C).
• Heated-bed temperature: 122–158°F (50–70°C).
• Print speed: 30–70 mm/s.

These are supplier-recommended starting ranges. Adjust settings for your printer and model, and stay within your printer manufacturer's supported limits.

What to expect

Color transitions depend on the selected style, the starting position on the spool, and the amount of filament used. Smaller prints may not display every color, and the outermost spool color may differ from the reference example. The gradient is a sequence of colors along the filament, not a heat-activated color-changing effect.

Package includes: One 2.2 lb (1 kg) spool of rainbow silk PLA filament in your selected style. Printed models and a 3D printer are not included.
