Creality 3D Printer Filament PLA PRO (PLA+) 1.75mm Colourful, Toughness Upgraded Dimensional Accuracy +/- 0.03mm, 1kg Spool(2.2lbs) Ender PLA Plus Filament for Most FDM 3D Printers

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

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.

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.

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.

Loaded this filament into the K1C and ran it at 300mm/s—no clogs, no stringing, just clean extrusion and crisp layer bonding. The color transitions are smooth and vivid, especially on larger prints. The spool is neatly wound, vacuum-sealed with desiccant, and the filament diameter stays consistent at ±0.03mm. It’s got enhanced toughness compared to standard PLA, so prints feel more durable without sacrificing detail. Works great with both direct drive and Bowden setups, and it’s compatible with most FDM printers.
