Fantastic Color Change Effect: The Gratkit Matte Rainbow PLA filament offers a mesmerizing color transition every 8-10 meters, perfect for vibrant prints. Users love the smooth gradient and matte finish, which adds a unique aesthetic to their models.

Easy to Print: This filament is beginner-friendly, with excellent bed adhesion and minimal clogging. It works well on both high-speed and standard 3D printers, making it versatile for various projects.

High-Quality Finish: The matte texture hides layer lines effectively, giving prints a professional look. Many reviewers praised its print quality straight out of the box with minimal adjustments needed.

Packaging & Storage: While the cardboard spool is eco-friendly, some users noted compatibility issues with Bambu Lab AMS units. The included zipper bag helps keep filament dust-free, though opening it can be tricky.

Value for Money: Opinions vary—some find it worth the price for its unique color effects, while others feel it’s overpriced compared to standard PLA. However, fans of gradient filaments highly recommend it for artistic prints.
