Ordered 3 colors, they are amazing! I collect Fluorescant minerals, glass, and other items. Love 3D printing items for the many Fluorescant groups I belong to. This will be an added filament to the others and is being loved by many folks!! Great adhesion and print quality and the colors just pop when a uv light is anywhere close!!

Lights up like an LED in UV but it's so violently stringy even after drying it for 6+ hours it was still a giant spiderweb in my printer. Ruined several prints from all the stringing building up and knocking things over. And at $80/kg that's like $15+ to calibrate it if it even works.
