Glow-in-the-dark 3D printer filament – pretty self-explanatory. Leave your print in the light for a while, then flick the switch and behold that eerie green glow.
It doesn’t have to be green, of course. It can also be blue, red, pink, yellow, or orange. But green is so cool…
So, how does it work? It all comes down to the phosphorescent materials mixed in with the PLA or ABS base. Thanks to these added materials, a glow-in-the-dark 3D printer filament is able to absorb and later emit photons, which are kind of like tiny particles of light. This is why your prints will only glow after being in the light – they have to store the energy before they can release it.
For best results, consider printing with thick walls and little infill. The thicker your walls, the stronger the glow!
When Should I Use Glow-in-the-Dark 3D Printer Filament?
Thinking about that eerie green glow, it almost doesn’t even seem necessary to suggest using a glow-in-the-dark 3D printer filament for Halloween projects, like jack-o’-lanterns or window decorations. Other examples of where these filaments really shine – er, glow – include wearables (think jewelry), toys, and figurines.
