YOUSU 3D Printer Filament Galaxy PLA Filament 1.75mm, 3D Printing Filament Bundle, Multi Color PLA Filament Glitter 250g X 4 Color Pack.

This material glows well, much better than I expected it too. I could tell the print was glowing in my hand in a dim hallway before I did the classic "turn the light off in the bathroom" method of looking at glow in the dark items. I'm probably going to buy a new small UV flashlight, the material is just makes it extra entertaining. Sunlight charges the material great, but LEDs and florescent lights struggle get the same intensity.As for printing? I'm frustrated that it is one of my best printing PLAs. It prints nicer at high speed than my high speed PLA.

Happy with the purchase

I was really excited to try this glow-in-the-dark 3D printer filament for some fun nighttime projects. The product description promised a vibrant glow after being charged with light, but after multiple prints and testing, I can confidently say this filament is a total letdown.I followed the instructions to the letter—exposed the prints to bright light (both sunlight and a strong LED lamp) for well over the recommended time—and still, nothing. No glow, not even a faint shimmer. In the dark, my prints just look like regular, dull plastic. I even tried different charge times and light sources, thinking maybe I was doing something wrong, but it made no difference.The filament itself prints fine, with decent quality and no clogging issues, but that’s not why I bought it. I wanted the glow-in-the-dark feature, and it simply doesn’t deliver. For the price, I expected something that actually worked as advertised. Instead, I got what feels like overpriced regular filament.If you’re looking for a true glow-in-the-dark effect, skip this one. I’m returning mine and searching for a brand that actually lives up to its claims. Super disappointed!

Each roll was very neatly rolled and printed very well. There was no stringing; I set the printer to 200°C and each color printed amazingly. Great adhesion with no failures. I’m very happy with this filament, I highly recommend and I would definitely buy again.

While I absolutely loved the 3 glitter filaments, I have to leave off a star because I could not use the color shifting roll. The color shifting filament roll that I received was so brittle, it would break just coming off the roll straight to my extruder and I couldn't print with it.However, I am very impressed with the strength and color of the 3 glitter rolls. I've never had a glitter filament to print well for me, but these did great once I tweaked my temps. They are also much stronger than most of the other pla filaments I've used. I love the sparkle and it takes a lot more force to break even small prints, than any of the other pla filaments I have used. While a slightly larger nozzle is recommended, I had no issues printing with a .04 nozzle. It does tend to be a bit stringy but I found it prints pretty well at a lower temp. I printed this little articulated spider on 190. There is still some minor strings but nothing that isn't easily removed. I am hoping to see large rolls of this glitter filament soon.

Right off the bat I need to say I purchased this in 2023 for a very specific set of projects, which then got delayed until 2025. So, let's keep this simple.Does it glow? Yes, but not as bright as it could be.How does it print? For PLA I had to set my Extruder to 210 Celsius and the bed to 60 just to get a decent print that would adhere to the bed. When I didn't, the material would not adhere to my textured bed and I ended up wasting the entire spool of purple filament.What is the condition of the filament? After a year in it's vacuum sealed bags, it was never opened and was kept in a cool dark location, it's very brittle. I mean super brittle. Any bend greater than 45 degrees puts you at risk of it breaking. If you don't have a runout sensor, be very careful or just get something else.And the one I never thought I would have to add to a review...How does it smell? It smells like rotten eggs and I had to turn on an exhaust fan to clear the room. It's horrible.I want to give it 2 stars, but I'm going to give it 3 because of how long it sat which could cause the issues with how brittle it is, how little it glows, and how bad it smells when printing.

Prints as expected so long as you follow the included recommendations. Prints well in both miniature and full size Prints. My photos are of the Chameleon Blue color. No issues with clogging or stringing. This pack includes a decent variety of colors, and the glitter shows best when it catches the light.

New to 3d printing. I'm using a bambu a1 with a ams lite. Only one of these worked for me. All the others have me errors on my machine and just doesn't want to work. If you are new like me, don't get this. I have used so many other filaments including silk and transparent. This one us do disappointing. I've set the temp on the extruder higher, lower, nothing wirks.
