This is the review my kids loved the most. In March 2021 I tested AzureFilm's Glow in the Dark PLA, and about 90% of what I printed ended up in their bedroom.
It really glows
As always with AzureFilm, from Sežana in Slovenia, the spool was wound in a really professional way and the unboxing was great. But the star here is the glow. I honestly wasn't expecting this much of it.
The CaliCat came out really well with no stringing. I didn't even have to cut anything, so it went straight into my CaliCat collection. Then I printed the MatterHackers filament astronaut at 150% scale. It's heavy, but it looks amazing when it glows in the dark. This model tells you a lot about a filament: how it handles cooling and how well tuned your slicer and printer are.
Prints for the kids
A rocket in vase mode, completely hollow, at 0.8 extrusion width as usual. It's nice and stiff and the kids haven't broken it yet. Then an experiment: a radiation warning symbol where I printed the base in glow PLA and switched to black PLA on top, so in the dark the glow shines through.
When the kids saw what I was testing, they were all over me: "Papà, print something for my room!" They're crazy about Halloween, so I printed a ghost for their wall. And I remembered having sticky stars all over my ceiling as a kid, falling asleep looking at them. So I found models on Thingiverse and printed loads of stars and moons, smiling and sad. Even if they're a bit rough, in the dark you only see the glow.
For something useful I printed my usual storage box and a small vase-mode holder for my spatulas next to my work area.
Settings
No special settings: I got the temperature right at 210 °C. The only issue was that taller prints, like the first CaliCat, detached from the bed. So I used a small raft on every print. Otherwise it prints like regular PLA.
I kept more than half the spool, vacuum-stored away from humidity, ready to fill the house with glowing prints when Halloween comes.
