OzFDM PLA Glow in the Dark Rainbow does double duty: a rainbow gradient by day and a soft glow once the lights go out. Charge it under sunlight or a UV lamp and your print keeps shining in the dark, making it a favourite for kids' toys, signage and novelty pieces that need to work twice as hard for their impact.

The rainbow colour shifts roughly every 20 to 30 grams as you print, so each model flows through the spectrum on its own without any manual colour changes or multi-material setup - a single, uninterrupted print gives you both the gradient effect during the day and the glow payoff at night. That makes it a strong choice for gifts, party favours, and any piece meant to be handled and admired in both bright and low-light settings.

Quality-assured PLA keeps printing uniform and stable throughout, so the glow pigment and colour-shifting effect don't come at the cost of reliable layer adhesion or consistent extrusion. As with any glow filament, give the print a solid charge under a strong light source before showing off the after-dark effect, and expect the glow to fade gradually over the course of the evening before it needs recharging again.
