As it prints, the filament transitions through red, orange, yellow, green, blue, and violet in smooth metallic gradients — creating prints that look like they were finished by a professional painter. High speed compatible up to 300mm\/s, vacuum-sealed with desiccant, 1kg spool.\u003c\/p\u003e\n\n\u003cp\u003eRainbow silk is the ultimate \"wow factor\" filament. It requires zero skill beyond loading the spool — the material does all the work, producing dramatic, multi-colored metallic prints that are impossible to achieve with single-color filaments without multiple spool changes or post-processing. It is one of the most popular filaments for social media, maker markets, and gifts.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Makes Rainbow Silk Different from Tri-Color?\u003c\/h3\u003e\n\n\u003cp\u003eOur \u003ca href=\"\/products\/iiid-max-high-speed-tri-color-silk-pla-filament\"\u003eTri-Color Silk\u003c\/a\u003e blends three specific colors (Blue, Yellow, Fuchsia) in metallic tones. Rainbow Silk goes further — it cycles through the full visible spectrum with gradual transitions between each hue. The result is more varied and unpredictable, with every section of the print showing different color combinations. Tri-Color gives you a controlled, harmonious palette; Rainbow gives you the entire rainbow in metallic silk finish.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePLA+ (Rainbow Silk High Speed formulation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDiameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.75mm ± 0.03mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpool Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1kg (2.2 lbs) net weight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePrinting Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e200°C – 230°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBed Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50°C – 70°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePrint Speed\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to 300 mm\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eColor Pattern\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFull spectrum gradient (Red → Orange → Yellow → Green → Blue → Violet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePackaging\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVacuum-sealed with desiccant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eTips for Maximum Rainbow Effect\u003c\/h3\u003e\n\n\u003cp\u003eThe color transition length is fixed by the manufacturing process, so the way it shows on your print depends on how much filament each layer uses. \u003cstrong\u003eTall, narrow models\u003c\/strong\u003e will show many color changes from base to top. \u003cstrong\u003eWide, flat models\u003c\/strong\u003e may show color shifts across the same layer. For the most dramatic rainbow effect, print models that are at least 10-15cm tall.
