Hello3D Silky Rainbow PLA Filament – 1.75mm, 1kg

Create vibrant, color-changing prints with Hello3D Silky Rainbow PLA Filament. This specialty PLA combines gradual rainbow transitions with a glossy silk-like finish, helping decorative models look polished directly from the printer.

As the filament feeds, its colors shift gradually through the spool. Larger or taller prints—and models that use more filament—typically reveal more of the transition, while smaller projects may show only part of the color sequence.

Why You’ll Like It

Printing Tips

• Silk PLA often prints best slightly hotter and slower than standard PLA.
• Reducing outer-wall speed can improve gloss, surface finish, and layer adhesion.
• Larger prints, thicker walls, or higher infill generally reveal more of the rainbow transition.
• Because silk additives can reduce layer adhesion compared with standard PLA, this material is best suited for decorative and visual parts rather than heavily loaded structural components.
• Store the spool sealed and dry when not in use for cleaner extrusion and surface quality.
