Rainbow PLA

Beginner

Color-Transitioning Polylactic Acid

A multi-color PLA filament that gradually transitions through a spectrum of colors along the length of the spool. Rainbow PLA uses co-extrusion or inline dyeing to create smooth color gradients without any manual filament swaps. The color cycle length varies by brand, typically repeating every 10-30 meters.

Nozzle Temp195–225°C
Bed Temp50–60°C
Print Speed30–50 mm/s

Printing Tips

  • Print at 200-210°C to keep color boundaries crisp; overheating causes colors to bleed at transition zones.
  • Taller prints show more color bands — scale models vertically if you want to display the full gradient.
  • Use vase mode for the smoothest color transitions; solid infill creates random color mixing in the interior that bleeds through thin walls.
  • Plan your Z-height to align interesting color transitions with prominent features of the model.
  • Avoid multi-part prints from the same spool if you need color matching — each segment starts at a different point in the cycle.
