Luminous Rainbow PLA for FDM printers

eSUN Luminous Rainbow PLA is a 1.75 mm filament that glows after absorbing light. The multicolour spool shifts hue every 15 to 20 metres, creating a rainbow effect on decorative prints, toys and art pieces. It suits any FDM printer that accepts 1.75 mm PLA.

Tangle-free spool and recommended temperatures

The spool uses adaptive winding to prevent overlap and tangling. Printing temperature range is 190 °C to 220 °C, with a bed at 45 °C to 60 °C and fan at 100 %. Diameter tolerance is 1.75 ± 0.05 mm for consistent extrusion.

Check nozzle compatibility and storage needs

Ensure your hot-end can reach at least 220 °C and that the nozzle is not worn by abrasive materials. The filament contains phosphorescent additives, so store it away from prolonged direct sunlight to preserve glow performance.

Questions about this item

How can I verify the filament is printing correctly after loading it?

Watch for smooth extrusion at 190–220 °C nozzle temperature, consistent 1.75±0.05 mm diameter, no bubbles or warping, strong bed adhesion, and a clean rainbow colour shift every 15–20 metres.

What comes on the spool and what must I supply myself?

The box contains a 1 kg spool of 1.75 mm Luminous Rainbow PLA; you must provide a compatible FDM printer, a heated bed capable of 45–60 °C, and an adhesive surface such as textured paper, PVP glue, glass, carbon-fibre sheet or PEI.

Which version or capacity should I choose for a glow-in-the-dark rainbow effect?

This model is offered only as a 1 kg spool of 1.75 mm Luminous Rainbow PLA; choose it when you want multicolour glow prints that charge under UV light and shine in the dark.
