eSUN PLA-Matte Rainbow 3D Printer Filament 1.75mm 1kg

eSUN PLA-Matte Rainbow is a PLA-based aesthetic filament that combines a soft matte surface with colorful rainbow-style transitions. It is designed for users who want decorative prints with a smooth, refined appearance and natural color variation without using multi-color printing hardware.

Based on eSUN’s PLA-Matte material, this filament offers easy printability, low shrinkage, and a delicate surface finish that helps reduce the visibility of layer lines. The rainbow color themes make each printed model look more dynamic, especially on larger prints where more of the color transition can appear.

PLA-Matte Rainbow is ideal for decorative models, cosplay props, display pieces, artistic prints, concept models, and creative prototypes where surface finish and visual style are important.

Key Features

• PLA-based matte rainbow filament

• 1.75mm filament diameter

• 1kg spool size

• Smooth matte surface with reduced visible layer lines

• Rainbow color transition effect

• Easy to print without an enclosed chamber

• Low shrinkage to help reduce warping and cracking

• Support structures are easier to remove

Matte Rainbow Appearance

PLA-Matte Rainbow creates a colorful gradient effect while maintaining a soft, non-glossy surface finish. The matte texture gives printed models a cleaner and more premium appearance, while the rainbow transition adds visual depth and variation.

The final color effect depends on the model size, print orientation, wall thickness, and amount of filament used. Larger models usually show more of the rainbow transition, while smaller prints may display only part of the color sequence.

Smooth Surface Finish

The matte finish helps hide layer lines and gives printed parts a delicate, smooth appearance. This makes the filament especially suitable for models that are intended to be displayed directly after printing, with minimal sanding or painting.

It works well for curved models, vases, figures, props, ornaments, and decorative parts where surface quality is an important part of the final result.

Easy PLA-Based Printing

PLA-Matte Rainbow prints with a familiar PLA workflow and does not require a closed chamber. Its low shrinkage helps reduce warping and cracking, making it suitable for both small decorative prints and larger models.

The material is also suitable for early concept models and rapid prototyping when a clean visual finish is required.

Support Removal and Post-Processing

Compared with many standard filaments, support structures can be removed more easily from the model surface. This helps preserve the smooth matte finish and reduces post-processing effort on models with overhangs or detailed geometry.

Feeding and Printing Tips

PLA-Matte Rainbow is softer than some other filaments, so the extruder tension should not be set too tight. Excessive pressure on the filament may affect feeding stability and print quality.

For best results, store the filament in a sealed bag or dry box after opening. If moisture absorption is suspected, dry the filament before printing to improve surface quality and reduce stringing.
