For best result, we recommend the prints being charged under UV light or direct sunlight, or at least 60w equivalent led light. 

The glow will be most visible in dark room for about 10-30 minutes after it's fully charged. 

Printing tips:

1. Use hardened steel nozzle or stainless steel nozzle. Brass nozzle will wear out.

2. Nozzle temperature 200-210°C, this glow in dark PLA prints similar to our regular PLA.


Hunted Ember (White under daylight, Orange in the Dark): This Glow-in-Dark color conveys the transformation of the color from a calm, subdued appearance in daylight to a dynamic and fiery glow in the dark, reminiscent of an ember.

Stardust Glow ( Green Sparkle in Dark): This Glow-in-Dark color conjures the imagery of celestial magic and the enchanting glow of stardust.
