IntermediateGlow-in-the-Dark PLA
GITD PLA · Phosphorescent PLA
Phosphorescent PLA that charges under light and glows in the dark. Beautiful but very abrasive — a hardened nozzle is required.
Print temperatures
Nozzle 205–225 °C Bed 50–60 °C
Glow PLA charges under light and glows for minutes to hours afterward, with green the brightest and longest-lasting color.
The catch: the phosphor is harder than brass, so glow filament is often more abrasive than carbon fiber — a hardened nozzle is essentially mandatory.
Strengths & trade-offs
- Genuine phosphorescent glow (recharges indefinitely)
- Fun for toys, décor, and signage
- Prints at PLA ease otherwise
- Green variants glow brightest
- Charges from any light
- Highly abrasive — hardened nozzle required
- Glow fades over minutes to hours
- Phosphor reduces strength
- Uneven glow if particles settle
- Needs slower speeds

Did you know
- Glow filament is often more abrasive than carbon fiber — strontium aluminate is harder than brass.
- The phosphor doesn't wear out — it can be charged and discharged effectively forever.
