Spectrum PLA Rainbow is a unique PLA SILK–based 3D printing filament, manufactured using special color concentrates that create a satin gloss finish and smooth color transitions along the entire filament length. During printing, colors gradually change, giving every model a distinctive and eye-catching appearance.

The filament retains all mechanical properties of standard PLA while offering excellent dimensional stability, easy printing, and reduced visible layer lines. It is ideal for decorative models, design elements, prototypes, and artistic projects where visual appeal is essential.

Spectrum PLA Rainbow is compatible with most popular FDM 3D printers and integrates seamlessly into existing printing workflows. The combination of precision printing and striking color effects gives your projects an entirely new dimension.

Packaging and quality control

The filament is wound on a transparent spool labeled with material type, diameter, and recommended printing temperatures. Each spool is vacuum-sealed with a moisture absorber and packed in original Spectrum Filaments packaging.

With VERIFY YOUR SPOOL, every 1 mm of filament is continuously measured in two axes with an accuracy of ±0.8 µm. Quality data available for each spool include:
• diameter profile
• average diameter
• ovality
• standard deviation
