YOUSU 3D Printer Filament Bundle, Glow in The Dark Filament Multicolor, Green, Blue, Purple and Rainbow, PLA Filament 1.75 mm, Dimensional Accuracy +/- 0.03 mm, 250g X 4 Pack

I am seriously impressed with this TPU combo pack! The colors (Blue, Green, Yellow, and Purple) are super vibrant in normal light, and the glow-in-the-dark effect is just incredible. I printed a set of gummy bear models to test it out, and they came out looking amazing both in the light and when glowing. The filament feeds smoothly, has great layer adhesion, and is flexible without being too tricky to work with. The glow lasts a surprisingly long time once it’s charged up under light, and each color has its own unique glow effect that really stands out. This pack is a perfect mix of fun and quality—I love having multiple color options in one set. If you’re looking for a TPU that’s flexible, reliable, and also adds some serious wow factor with glow-in-the-dark, this is the one to get. Highly recommend!

The glitter in these items make the prints sparkle in the light. I ran these using the generic PLA settings on my printer, and did not experience any feeding issues or clogs. I did run them using my external spool holder, and not my AMS. The Galaxy Black has multicolored glitter. The item I made, using vase mode, allowed the sparkle to shine through, but the black filament color allows enough light through, to make a stunning looking light or lamp. The Glitter Gold Black is the black base filament with gold glitter, and the clear glitter layer again allows light to shine through. The Black Colorshift is a bit different than the ones with glitter pieces. You get a much more uniform sparkle throughout, which makes the color very even and consistent. Finally, the Green Starry, is like the other glitter / black colors. While the green glitter shows fairly well, it isn't quite as prominent as the multicolor or gold. Overall, I would say the material is good quality and performed well, as the pieces I made seem quite sturdy, especially the little articulated caterpillar. I would buy these items again!

Really good to use. Beautiful glow. Prints nice and smooth.

So far have only used the blue and purple. Were first time 3D printer users and I like this filament, I am disappointed the blue glows but the purple doesn’t. And the purple isn’t that dark of a purple.

I received my order yesterday and immediately ran a test print. The filament quality is impressive—the first figure came out flawless with great adhesion and a smooth finish. However, I am rating it 4 stars for two reasons: First, the promised filament sample mentioned in the offer was missing from the package. Second, the product imagery can be misleading for beginners; although the weight specifications are clearly stated for each spool, the photos make them appear significantly larger than their actual physical size. Overall, it is a high-performing product so far. I look forward to seeing if this consistency and quality hold up throughout the entire spool.

Pleasantly surprised! Printed some dragons and they look great! Changing the orientation of the print will yield different colors. See video. The yellow comes out more of a gold and the red is more of a magenta. You'll get shades of purple and green as well. Rainbow filament basically. Structurally, same as any other silk filament. As in, more brittle than normal. Pay attention to the geometry that the slicer outputs. With dragons for example, you want your links to be at least 4 lines wide (1.6mm) or the kids will snap the plastic. Bed adhesion is as expected. I have a Ender 3 V2 with a glass bed. Needs gluestick for this filament. Temperature tower showed 200 as the optimum temp. Anything higher and you get whiskers and strings everywhere. The spool I got shows no issues of tangles and color orientation looks consistent throughout (there are windows on the spool) What can you print with this? Mostly larger curvy organic shapes. Large flat surfaces don't look that good as the color gets splotchy. Flat tops and bottoms just look like rainbow noise. Small details as well. The just look grey from farther away. To summarize, with the right model, results are top notch.

Exceptional filament. The best TPU I've ever used. Just enough rigidity and softness for any project out there. My go-to for any TPU now and forever. No problems printing whatsoever. I used a 0.4 nozzle at 0.08 layer line and it printed flawless. Extraordinary consistency. Roll after roll. I had absolutely no issues. Other manufacturers definitely fall short. This is the best TPU I've ever used for anything in my print farm

The purple one doesn't glow to well but the other colors are great. However there not as big as I was hoping.

Tolles Filament mit einem schönen Farbspiel. Leider sind die Rollen breiter wie die Rollen anderer Hersteller. Sie passen zwar gerade so in das AMS vom Bambulab X1C, scheuern aber an beiden Seiten und deshalb kommt ständig die Fehlermeldung "AMS-Hilfsmotor überlastet". Das nervt und trägt auch nicht zur Haltbarkeit des Hilfsmotors bei. Entweder über die externe Filamentzuführung nutzen (nicht immer unbedingt sinnvoll), umspulen (mache ich ungern) oder einfach die Finger davon davon lassen (meine Empfehlung, wenn das AMS von Bambulab beenutztz wird).

Ottimo filamento TPU, stampa con settaggi generici con BambuLab X1C perfetti!

Well worth the money

Rimasto davvero sorpreso .Il prodotto si presenta benissimo ,ben sigillato sottovuoto.Il filamento è avvolto benissimo intorno alla bobina cosi da non presentare intreccio e scorre benissimo.Con le giuste impostazioni stampa perfettamente .Super consigliato
