SUNLU PETG Rainbow

Strong, Vibrant, and Multi-Colored Prints

SUNLU PETG Rainbow brings together strength, reliability, and eye-catching color transitions in one high-performance filament. Made from durable PETG (Polyethylene Terephthalate Glycol), this filament offers the best of both PLA and ABS properties, stronger than PLA and easier to print than ABS, while delivering a smooth, glossy finish and excellent layer adhesion.

What sets this version apart is its dynamic rainbow color gradient. As you print, the filament gradually shifts through a vibrant spectrum of hues, allowing your projects to showcase beautiful, multicolored effects without needing to manually switch filaments. This makes it perfect for aesthetic models, decorative items, cosplay props, or any print where visual impact matters as much as structural integrity.

SUNLU PETG Rainbow is engineered for dependable performance across a range of printers and applications. It features low shrinkage and minimal warping, making it suitable for larger prints or projects requiring dimensional stability. The filament also resists moisture absorption better than PLA, reducing issues with bubbling or inconsistent extrusion.

Thanks to its toughness and flexibility, SUNLU PETG Rainbow performs well under mechanical stress and is ideal for both functional and artistic applications. Whether you’re creating prototypes, display pieces, or everyday-use objects, this filament provides the durability you need with a finish that stands out.
