YOUSU's 3D Printer Filament Galaxy PLA Filament offers a vibrant and versatile option for 3D printing enthusiasts. This multi-color bundle includes Glitter Galaxy Black, Chameleon Blue, Glow in the Dark Green Starry, and Glitter Gold, each weighing 0.25kg. The filament is designed for smooth printing with minimal warping, stringing, or clogging issues.

One of the standout features is the Glow in the Dark Green Starry filament, which glows brightly under bright or ultraviolet light. It’s perfect for large models and fast printing, producing smooth surfaces with excellent layer adhesion. The filament is also more rigid than many competitors, ensuring durability and precision in prints.

Users have praised the consistent quality and dimensional accuracy of YOUSU filaments. They feed smoothly through printers without tangling or clogging, making them suitable for various FDM 3D printers, including popular models like Bambu Lab Printers. The vibrant colors and professional finish of printed objects have also been highlighted as major positives.

However, some users noted challenges with certain colors, such as brittleness in the Glow in the Dark Green Starry filament before drying and clogging issues with the Chameleon Blue filament. These issues can often be mitigated by using a larger nozzle (0.6mm) and adjusting print settings.

Overall, YOUSU's PLA filament bundle is a cost-effective choice for those looking to experiment with different colors and effects in their 3D prints. While it may require some tweaking of settings for optimal results, its reliability and vibrant finishes make it a worthwhile investment for both beginners and experienced users.
