The PLA Gradient Rainbows filament from the Panchroma collection is a vibrant and versatile option for 3D printing, featuring a unique gradient effect that smoothly transitions through a spectrum of colors in one spool. This filament stands out by offering a variety of surface finishes, including matte, satin, translucent, and luminous, allowing for exceptional creative possibilities. With minimal visible layer lines, it is perfect for producing visually stunning prototypes, decorative items, or artistic creations that require a bold, colorful impact.
As part of the Panchroma range, this filament highlights the brand's commitment to delivering innovative color effects and high-quality performance. The carefully engineered formulations ensure seamless color transitions while maintaining consistent printability. Whether you’re crafting functional designs or eye-catching pieces, the PLA Gradient Rainbows filament offers a dynamic and artistic solution to elevate any 3D printing project.
Printing with PLA Gradient Rainbows is simple and reliable, with recommended extrusion temperatures between 190-230 ºC and a bed temperature of 25-60 ºC. Capable of speeds up to 200-300 mm/s (except for the Pastel variant), this filament adapts to both high-speed and detail-oriented workflows. Its smart spool design, featuring an anti-slip edge, ensures smooth handling and compatibility with automated material systems like the Bambu Lab AMS, making it an excellent choice for creating colorful, high-quality 3D prints with ease. It must be kept in mind that the Luminous variant requires the use of an abrasion-resistant nozzle due to the contained abrasive particles.

Like any 3D printing filament, the Panchroma PLA filaments should be stored properly in order to avoid their deterioration and, in consequence, extrusion problems and inferior print quality. The spool can be stored in an airtight plastic bag, in a resealable bag with a desiccant capsule, or in a smart filament container. If the filament has absorbed too much moisture, it must be dried before printing in a filament dryer for 6 hours at 55 ºC or in the PolyDryer solution. The recommended settings are setting 1 for Panchroma PLA Silk and others, and settings 1-3 for PLA Matte and Satin.
The Panchroma PLA filaments should be extruded at a temperature of 190-230 ºC on a bed heated to 25-60 ºC. It is recommended to use the cooling fan at 100% but a printer with a heated chamber is not needed. As far as the printing speed, it is recommended to use max. 200 mm/s for the PLA Silk and other Panchroma PLA varieties, max. 300 mm/s for the PLA Satin and Matte PLA, and max. 400 mm/s for CoPE.
Complex parts can be 3D printed with the Panchroma PLA filaments with the help of support filaments such as the PolySupport filament or the PolyDissolve S1 filament.
Panchroma PLA Glow and Panchroma PLA Luminous are glow-in-the-dark materials enriched with an abrasive additive, making a hardened nozzle essential for printing. These filaments should not be used in AMS systems with plastic gears or tubes due to their abrasive nature.
