Glow in the dark 3D Printer Filament


Glow in the dark 3D Printer Filament(PLA or ABS) is in fact nothing else but standard PLA/ABS filament to which the manufacturer added a so-called “phosphorescent material”. Manufacturers most commonly add pigments of strontium aluminate, which are materials which will “glow” for a certain time, after they have been exposed to a light source, like a flashlight or sunlight.

This glowing is scientifically referred to as phosphorescence, which is a “process in which energy absorbed by a substance is released relatively slowly in the form of light”.

Actually, the pigments simply absorb the photons contained in the light source and they will re-emit a part of this absorbed light over a certain period of time. This process of “phosphorescence” is what we most commonly refer to as “glowing”. This glowing can especially be well observed in a dark environment, that’s why these types of materials are commonly referred to as Glow in the dark 3D Printer Filament.

Using Suggestion

When it comes to Glow in the dark 3D Printer Filament, just proceed as if you would print with standard ABS or PLA, no special precautions or instructions are necessary. I recommend that you start with your regular ABS/PLA settings and start fine-tuning extruder and print bed temperatures only if necessary.

What you should know though is that Glow in the dark 3D Printer Filament may look quite different when exposed to day light compared to when they are in glowing mode. For example, green glow 3D filament has a whitish/translucent appearance which can make it tricky to spot issues during printing.

Pro tip: in order to get the best glowing prints, it is recommended that you slice your prints with no or the least amount of infill while adding a few more shells than usual. The thicker the walls of your 3D print, the better it will glow in the dark afterwards.
