Quick Answer

How does glow-in-the-dark PLA work?

The filament contains photoluminescent pigment that stores light energy and re-emits it slowly in the dark. In this grade, the pigment is suspended in the translucent Crystal Rainbow PLA body, which lets light pass through and makes the afterglow appear brighter and more even.

01 · Why this one

Product highlights

4 reasons

Crystal Rainbow chemistry adds a translucent gem-like body to the glow, giving prints depth and shine in daylight and a strong afterglow in the dark.

Laser-measured 1.75mm diameter with even, tangle-free winding keeps glow pigment distribution steady, so the whole part glows evenly instead of in patches.

Prints on standard FDM printers at the 220°C nozzle temperature on the label

a brass nozzle is fine, and Bambu Lab, Creality, Prusa or Anycubic users get clean glow parts with ordinary PLA settings.

Frequently Asked Questions

How does glow-in-the-dark PLA work?
The filament contains photoluminescent pigment that stores light energy and re-emits it slowly in the dark. In this grade, the pigment is suspended in the translucent Crystal Rainbow PLA body, which lets light pass through and makes the afterglow appear brighter and more even.
Will it work with my printer?
Yes, standard 1.75mm PLA that runs on any FDM machine, including Bambu Lab, Creality, Prusa and Anycubic. The glow pigment is not highly abrasive, so a brass nozzle works, though a hardened nozzle lasts longer for heavy users.
What settings do you recommend?
Use the 220°C nozzle temperature on the label with a mildly heated bed and moderate speed. The pigment slightly changes flow, so keep a steady extrusion speed and avoid over-retraction, which can create air gaps that dull the glow.
How long does one spool last?
Glow parts are usually small decorative objects at low infill, so a full spool lasts many prints; keychains and night lights use only a few grams each. Slice your model for an exact estimate.
What colors are available?
Two Crystal Rainbow glow shades: Green Fluorescent, which glows a bright green, and Orange Flame, which glows a warm orange. Both have the translucent rainbow body in daylight.
What speed should I use?
Moderate speeds around 40-60 mm/s work best to keep the glow pigment evenly distributed; slower outer walls give the smoothest translucent surface. Avoid very high speeds, which can streak the pigment.
Is it for prototypes or finished parts?
Finished decorative parts: night lights, keychains, signage, toys, Halloween and party props and art pieces. It is not meant for structural loads, but for anything that must glow, it is the end-use material.
How should I store it?
Keep the spool in the resealable bag with desiccant away from humidity. Store it away from direct sunlight when possible, since the glow pigment is charged by light but extreme UV exposure over time can fade it.
