Glow-in-the-dark rainbow PLA

This 1.75 mm filament combines a fast colour-shift rainbow effect with glow-in-the-dark properties for FDM printers and 3D pens. Each spool holds 1 kg net weight and changes hue every 5 to 10 metres during printing. The material is formulated from premium raw stock to maintain a long-lasting luminous effect after charging.

Tangle-free vacuum-sealed spool

Every spool ships vacuum-packed with desiccant and a reusable zipper bag to keep the filament dry and clean. The supplier guarantees 100 % tangle-free winding before the package is opened, and the spool includes holes to secure the free end between prints. A 0.4 mm or larger nozzle is recommended for best results.

Faster colour transitions than standard rainbow PLA

The colour shift occurs noticeably quicker than typical gradient filaments on the market, producing vivid multi-colour prints without manual filament swaps. Builds that need a single solid colour or a predictable colour sequence will not suit this material. Exposure to strong sunlight for long periods is discouraged to preserve the glow performance.
