How does the glow effect work?
Strontium-aluminate glow pigment is pre-mixed into the PLA; it absorbs UV and daylight and re-emits a soft glow for hours after the lights go out — no batteries, no wiring.

Frequently Asked Questions
How does the glow effect work?
Strontium-aluminate glow pigment is pre-mixed into the PLA; it absorbs UV and daylight and re-emits a soft glow for hours after the lights go out — no batteries, no wiring.
Will this glow filament work in my printer?
Yes — it is standard 1.75mm filament on a 1kg spool, compatible with Bambu Lab, Creality, Prusa and other FDM printers; a 0.4-0.6mm nozzle works fine.
What settings should I use?
Set the nozzle to 220°C, the bed to 45-60°C, and print at 40-60mm/s; avoid heating above 230°C because excess heat can degrade the glow pigment.
How much filament is on one spool?
Each 1kg spool is a confirmed 335 meters of 1.75mm filament — roughly 25-45 small glow parts or several larger night-light models.
What do the three rainbow series look like?
Candy is bright and playful, Macaron is soft pastel, and Forest leans to natural green tones; Night-Glow Rainbow 5#, 6# and Crystal variants offer different glow colors in daylight.
What speed range is recommended?
30-70mm/s works well; slower speeds give a silkier surface and make the glow pigment more visible in the printed walls.
What should I print with glow-in-the-dark PLA?
It is a decoration material: night lights, stars, keychains, dinosaur toys, signage and party favors — the wow factor is the product, so keep it away from load-bearing parts.
How should I store it so the glow lasts?
Keep it vacuum-sealed with desiccant and away from humidity; the pigment itself stays active indefinitely in dry storage, and the glow only needs exposure to light to charge.
