Great glow in the dark filament. Prints well after drying. California filaments are great quality and the variety of colors is extremely helpful.

I like the translucent look of this color, and it has a nice level of glow.

Never printed with glow in the dark, used just a standard brass nozzle so understand that. First layer goes down a bit wonky, but just let it ride because it prints fine. Didn’t change any settings. Comes out shiny yellow and glows in the dark very well. Best PETG on the market

This is under a black light but it’s crazy bright even after the black light is turned off.

I’ve used all 4 rolls I’ve bought from California filament in my A1. Won’t be purchasing from anywhere else at this point as it has not let me down yet. This is an RC body I printed.

Haven’t printed with it just yet, going to dry it in a few days. Held a blacklight on it for a few minutes and this was the result. Very impressed to say the least!

This filament is fantastic; the flow, the layer adhesion, and no stringing. It looks good both in light and the dark. It has a nice glow.

In the daylight this is almost a high vis or safety yellow, but with the lights off it's a bright glow in the dark. The glow lasts for quite a while and even stays dim for several hours. I definitely had to dry this PETG more than normal, but once it's dry it prints gorgeously.

Smooth prints without a problem. The yellow is vibrant and the glow is bright. Great material! I would definitely recommend this to others who are interested.

I love the California Glow PETG filament. It prints so much nicer than some others that have very high friction. The only downside I see is that my last 2 orders shipped on cardboard spools which are not compatible with Bambu spools, even if you remove the sides. You must respool these if you want to use with an AMS system. The vacuum sealing of the bags deforms the cardboard sides too much to reliably use in an AMS. I wish California offered all of their spools with a Bambu compatible refill option.

Great color, in light and at night. Has a nice glow to it, as long as it's able to charge up enough.

I am making door wedges for the guys at my fire department and this filament worked flawlessly. The prints popped right off the bed and the supports were easy to remove.

Great as always. Perfect amount of shine. Prints great on Bambu printers.

Just started a print with the glow PETG filament. Printing with a .25mm layer height. 55% fill. 240 degrees C for the print temp. 80 degrees C for the bed temp. So far, it's looking good!
