PETG Rainbow Mini 
PETG Rainbow Cosmic Colors Brand: Yiqiu3D · Single-color prints look flat next to multicolor marketing: this rainbow PETG shifts hue along the strand, so vases, toys and signage show smooth color transitions from a single spool and a single extruder.
Rainbow PETG is extruded with segments of different pigments joined in one strand, so the color cycles as the spool feeds. Because the transition is continuous, a single print sweeps through multiple hues without a multi-material setup.
Full answers belowBest for: A strong all-rounder for end-use parts needing toughness and easy printing without a heated chamber - available in 4 colours; lead colour PETG Rainbow Candy Color. Not ideal for: Avoid where very fine cosmetic detail leads; PLA or resin prints cleaner surfaces - available in 4 colours; lead colour PETG Rainbow Candy Color.
Nozzle 230-260°C
Harsh color jumps ruin the gradient: the three curated series, Mini, Macaron and Cosmic Colors, each blend hues in a different mood, from soft pastels to deep space tones.
Transition filament often prints patchy: laser-measured 1.75mm diameter with even, tangle-free winding keeps the color flow steady, so transitions come out smooth instead of streaky.
Rainbow effects usually mean fragile material: this grade stays true PETG, tough and low-warp, printing at the 220°C nozzle temperature shown on the label on Bambu Lab, Creality and other mainstream machines.
