Creality Automated Filament Feeder, Auto Refill and Switch, Multi-Color Printing, Leftover Utilization, 7 Optical Sensors, High-Torque Dual-Gear Extruder for Most 1.75mm 3D Printer

Auto Refil & Uninterrupted Printing：Automatically switches to backup spool when filament runs low, no manual supervision needed. 7 high-precision optical sensors real-time monitor filament feeding, effectively avoid print failure caused by filament run-out or breakage. Leftover Filament Utilization & Zero Waste：Intelligently connects and uses leftover filament segments, maximizes material utilization and reduces waste. One-touch auto unload function simplifies filament changes, greatly improving printing efficiency. High-Torque Stable Feeding System：Equipped with high-hardness dual-gear extruder (6.25:1 reduction ratio), provides strong and stable feeding torque, wear-resistant and durable. Compatible with 1.75mm FDM filament (not compatible with TPU). Multi-Color Printing & Easy Operation：Supports manual filament switching to realize multi-color printing on standard 3D printers, enrich creation effects. Compact design with magnetic cover and anti-slip mat, stable placement and easy maintenance. Wide Compatibility & Plug-and-Play：Compatible with most FDM 3D printers; official adapters available for special PTFE tube structures. Simple 3-step installation, connect power and PTFE tube to use, no complex setup required.
