I’m finally getting around to messing with this stuff. Now I can balisong in the dark.
Step 2 is determining how badly all the particles of gumf in this filament negatively impact the mechanical strength.
Edit: I probably should have said this in the first place, but this is Overture green glow PLA.
The model is my Rockhopper balisong utility knife. Go check it out – it’s fully printable, even the hardware.
From a chemical composition standpoint I couldn’t tell you, but my off-the-cuff testing indicates that the glow remains visible for quite a few hours – All night, in fact, though obviously tailing off in brightness considerably as time goes on.
