What is this filament, and how does the glow effect work?
It is a PLA plastic with a light-charged glow pigment, and part of the range also carries the silk compound: the glow colours emit a soft light after being charged under a bright lamp or daylight, while the silk colourways give a glossy sheen. The effect is qualitative, so charge time and afterglow vary with print thickness, pigment load and the light source used. It is a plastic, not a metal or stone.
