- FAST HEATING – Enjoy fast and efficient heating with 3 minutes fast heating at 185°C, perfect for those who value speed in their 3D printing process. Note: We recommend using an official USB cable and a 5V-2A adapter to ensure the filament connector is turned on properly.
- Effortless One-Click Operation - Designed for convenience, a one-click operation and adjustable temperature settings provide an easy and user-friendly experience, allowing you to focus more on your creativity.
- COMPATIBLE WITH VARIOUS MATERIALS - With a maximum temperature of 240℃, this connector is highly versatile, compatible with popular filaments such as PLA, PETG, ABS, and PA/PC, so you can explore a wide range of materials with confidence.
