SUNLU Glow in the Dark PLA — Luminous Filament

SUNLU Glow in the Dark PLA is a PLA loaded with phosphorescent pigment that stores light and glows once the room goes dark. Charge a finished model under a lamp, sunlight, or especially UV light, and it softly glows for minutes afterward. It's a great pick for decor, signage, holiday props, and Halloween figures, and it prints as easily as standard PLA on virtually any 1.75 mm FDM machine.

Print Settings

• Nozzle temperature: 200–210 °C
• Bed temperature: 50–65 °C (you can also print unheated with a glue coat)
• Print speed: 50–100 mm/s
• Diameter: 1.75 mm, tolerance ±0.03 mm
• Density: 1.24 g/cm³, elongation at break around 4%

It glows green, blue, yellow, and orange — perfect for night lights, stair markers, cosplay masks, and souvenirs. Each spool is dried for 24 hours and vacuum-sealed with desiccant before packing, so it prints clean out of the box with no bubbles or clogs.
