3D Printer Filament Multicolor | 1KG Rainbow PLA+ Filament 1.75mm, PLA Plus Strong Toughness Dimensional Accuracy +/- 0.03mm, PLA Pro for Most 3D Printer

Great rainbow filament. Though I do wish the colors were closer together. It creates the rainbow effect, but its wider layers than I think I wanted. Still a beautiful filament and prints well

It’s good filament I just wish the color would change more often. It’s good if you’re making big prints but if you’re just making small ones, you’re gonna get a lot that are the same color. Still it adds a lot of variety and is good if you want some color but don’t want to buy 10 different rolls of filament

he rainbow PLA+ filament arrived in a resealable package that kept it fresh and protected. The colors are bright and vibrant, high quality prints so far with the few easter eggs we printed as gifts for people. Performance & Usage: I've been using this filament for a few months now, and it has exceeded my expectations in terms of performance. It prints consistently with minimal stringing or warping, and the color remains vibrant. Pros: Offers excellent toughness and durability, easy to work with on my 3D printer, and produces high-quality prints with great attention to detail. Consistent performance, suitable for various 3D printing projects, and a reasonable price point about $22 /1kg Final Verdict/Recommendation: Highly recommend for anyone looking to achieve high-quality prints with their 3D printer, particularly those who value the importance of filament quality and consistency. It worked great in our Babbu Lab P1s! and Printed 6 of the infinite easter egg fidgets for Easter this year. These were a huge hit. colors are bright vibrant.

Picked this up mostly out of curiosity -- I run an AD5X with a 4-color AMS so I don't usually need rainbow filament to get color variety, but I wanted to see how the gradient transitions looked on single-extruder prints and whether the PLA+ properties were actually an upgrade over standard PLA. Short answer: the color shifts are smooth and the filament itself is solid. No clogs, no tangles out of the box, and the spool was properly wound -- something I don't take for granted anymore. Came vacuum sealed with desiccant, which matters more than people realize. Wet filament kills surface quality and this arrived dry. The PLA+ flex resistance is noticeable compared to regular PLA. I did a bend test on a thin-walled section and it took a lot more abuse before showing stress marks. For functional parts where you want a little give, that's worth something. Where the rainbow effect lands on your print depends entirely on your layer height, print speed, and model size. Smaller models cycle through colors fast; larger flat surfaces let the gradient breathe. It takes some experimentation to predict where transitions will fall if that matters to you. At this price point it's an easy recommendation for anyone who wants interesting single-extruder prints without dialing in a multi-material setup. Good filament, no drama.

One of my favorite filaments. Runs beautifully every time, if I had a complaint it would be that it has too much pink in a cycle but that’s it.

Since this listing is for a number of different filament colors, and also randomly a filament dryer, note that my review is based specifically on the rainbow filament. I haven’t had any issues with clogging, adhesion on a smooth PEI print sheet (for Prusa CORE One) is good, layer adhesion is also good, and I haven’t experienced any other problems. One thing to note is that there is a lot of filament length in between color transitions. If you’re printing something relatively small, it’s likely to be all one color, with maybe a little bit of a second color added in depending on where you are in the stool. Where this filament really shines is on large prints, where you actually do get a second or maybe third color. In my opinion, they should have a version like this (and label it accordingly: because this isn’t what I was expecting), and a version for smaller objects where the colors transition more closely together and the rainbow repeats throughout the spool. I’ve only used about 1/10 of it so far (it’s on yellow now), so I’m not sure how many rainbows you get in a spool, or if it just starts on violet and ends on red. In the picture, you’ll see the “Robo Alpaka” print from Prusa’s test models. I thought it looked pretty decent and the print quality wasn’t bad.

Product I received looks nothing like the picture and basically stays the same color until the next one starts and doesn’t have a mix. The color looks to have been more shiny and gradient but it isn’t it’s very flat and matte almost. Very disappointing. Also had issues with multiple prints with it where it’s not adhering to the build plate.

Prints well and seems reasonably strong, but colors are not as vibrant as pictured
