PLA Glow-in-the-Dark

Intermediate

Polylactic Acid with Phosphorescent Additives (Strontium Aluminate)

PLA containing strontium aluminate phosphorescent powder that absorbs light and re-emits it as a visible glow in darkness. REQUIRES hardened steel nozzle.

⚠ IMPORTANT: Dry Your Filament Before Every Print

All filaments — including PLA Glow-in-the-Dark — absorb moisture from the air. Printing with wet filament causes stringing, bubbling, weak layer adhesion, and poor surface finish. This is the single most overlooked cause of bad prints.

Always dry your filament per the manufacturer's recommendations printed on the spool label before printing, especially if the spool has been open for more than a few days or stored in a humid environment. Read our complete filament drying guide →

About the Temperatures & Speeds Listed Below

The print temperatures and speeds shown on this page are general industry ranges — not a one-size-fits-all prescription. Every printer brand and model has different capabilities. A Bambu Lab X1C can print PLA at 500 mm/s; an Ender 3 with a Bowden extruder performs best at 40–80 mm/s.

Always follow your specific printer manufacturer's recommended settings and the temperature range printed on your filament spool label. Start at the lower end of the range and dial in from there.

02Handle with care during loading; avoid sharp bends
03Print with 3-4 walls and 30-50% infill; charge under UV flashlight for strongest glow

Print Speed by Printer Tier

Print speeds vary dramatically by printer. The speeds listed in product specs (like "500 mm/s") are maximum capabilities — not recommended everyday speeds. Use this table as a general guide and always follow your printer manufacturer's recommended settings.

High-End (Bambu X1C, P2S, H2D)

Print Speed: 150–300 mm/s

High-acceleration direct-drive systems. Follow manufacturer slicer presets.

Mid-Range (Bambu A1/A1 Mini, Prusa MK4, Creality K1)

Print Speed: 60–150 mm/s

Good performance at moderate speeds. Follow slicer presets for best results.

Entry-Level (Ender 3 series, Bowden extruders)

Print Speed: 30–60 mm/s

Start slow and tune up. Follow your printer manufacturer's recommended settings.
