💡 Recommendations and Usage Conditions

🔹 The TDS recommends drying PLA-Matte Rainbow at 60°C for more than 8 hours when needed.

🔹 The material is softer than some other filaments; avoid excessive extruder tension to maintain stable feeding and print quality.

🔹 For enclosed printers, eSUN recommends keeping the enclosure open while printing PLA, particularly when ambient temperature exceeds 32°C.

🔹 Store the filament tightly closed in a dry, cool place away from heat and moisture.
