Printed in glow in the dark green and blue! Took a lot of babysitting the printer all day to clear jams because the TEVO Tarantula has a terrible heat break design for 2 heads but it turned out quite nice. The blue is very dim compared to the green, and needs a lot of UV to energize it, I wouldn’t recommend it. Had to print at 90% to keep the priming tower on the print bed. The green is a little more clear looking and is called Super Glow - Natural from MG Chemicals. The glow in the dark blue is more milky white-ish from CCTREE - both via Amazon.
