ZYLtech Glow-in-the-Dark PLA Filament – 1.75mm, 1kg

Add a luminous surprise to signs, decorations, toys, cosplay pieces, and display models with ZYLtech Glow-in-the-Dark PLA Filament. After exposure to direct sunlight, UV light, or a bright LED light, printed parts store that energy and release it as a visible glow when the lights go down.

This specialty PLA prints similarly to standard PLA while adding eye-catching effects for Halloween projects, ornaments, gifts, game pieces, nighttime displays, and novelty prints. It works with both Bowden and direct-drive extruders, though its abrasive luminous additives make a wear-resistant nozzle the better choice.

Charging & Printing Tips

• Charge finished prints under direct sunlight, UV light, or a bright LED light for the strongest glow.
• A small flashlight may not provide enough energy to fully activate the luminous effect.
• Once fully charged, the glow is typically most visible in a dark room for approximately 10–30 minutes.
• Glow additives are abrasive and can wear brass nozzles. Use hardened steel or stainless steel, especially for more than occasional printing.
• Rainbow and multicolor effects need especially strong charging. When undercharged, green fluorescence may appear more dominant than the other colors.
• Store the spool sealed and dry when not in use to maintain smooth feeding and clean extrusion.
