🤝 High Compatibility
Compatible with the following printers: Bambu Lab X1/X1C and P1P (Monochrome printing), AnkerMake M5, Voron 2.4, Flsun V400, Creality K1/K1 Max and Ender 7, QIDI X-Max3/X-Plus3/X-Smart3, Raise 3D Pro 3 and RMF500.
📌 Notices
-
📦 To achieve the best printing effect, dry the filament at 55℃ for more than 4 hours. It is advisable to use the SainSmart dryer box during printing.
-
⚙️ Use a direct dual-gear extruder. GT-3 TPU is difficult to print with a Bowden extruder. If using Bowden, print slower — ideally 20 mm/s or lower.
-
🧹 After long printing times, impurities may remain in the nozzles. Use cleaning lines with the printer. Replace nozzles and throats if necessary.
