eSun PLA+ 1.75mm 1kg Luminous Blue filament — colour: Luminous Blue.
Glow-in-the-dark PLA that charges in ordinary light and gives it back in the dark. The glow is in the material, not a surface coating, so it cannot rub off.
eSun has been making 3D printing materials since 2007 and is now one of the largest manufacturers in the world — which means consistent quality between batches and a wide colour range.
Best for
- Switches, handles and markings in the dark
- Toys and costume parts
- Night lights and decorations
Worth knowing
The glow is strongest on thin walls and after bright light. The phosphorescent particles are abrasive — check the nozzle requirement in the specification.
Exact print settings, drying recommendation and printer requirements are in the specification table above.
