If you have a model printed with green GITD filament....
Never tried leds behind glowfill. I’d assume you’d want as close to green as you can get, blue and green mixed doesn’t make green I’d think
Thank you for the reply. The answer has to do with quantum physics. The blue LED imparts more energy to excite the "glow in the dark" filament. I found that a UV LED will make the filament glow the brightest.
