Unbelievably strong after-glow effect  

Spectrum PET-G Glow in the Dark is a PET-G-based filament blended with a concentrated phosphorescent pigment which causes the phosphorescence effect. Accordingly, once the printed items are exposed to an external light source, they will emit their own light. The material has all the typical characteristics of the pure PET-G – the added pigment has a neutral impact on the material's properties.
