Product description
Creality Automatic Filament Feeder AF-01 – Automatic Filament Feeder
Creality Automatic Filament Feeder AF-01 is an automatic filament feeding and spool-switching system designed to reduce print interruptions caused by an empty filament spool. It can automatically switch from a nearly depleted spool to a backup spool, making it particularly useful for long and unattended 3D printing jobs.
Key Features
- Automatic filament switching – switches to a backup spool when the current filament runs low.
- Auto refill – reduces the need for manual intervention during long prints.
- Efficient use of filament leftovers – helps make better use of partially used spools.
- 7 optical sensors – accurately monitor filament position and movement.
- High-torque dual-gear extruder – provides stable and reliable filament feeding.
- 6.25:1 reduction ratio – provides increased torque for dependable filament handling.
- One-touch filament unloading – simplifies filament and spool changes.
- Wide compatibility – designed for a range of Creality FDM 3D printers.

Continuous Printing
The AF-01 monitors the filament supply from the active spool. When the spool is nearly empty, the system can automatically switch filament feeding to a backup spool. This helps prevent failed prints caused by an empty spool and is especially useful for long-duration printing.
Better Use of Filament
The Automatic Filament Feeder can also help use partially depleted filament spools more efficiently. Remaining filament can be connected to the next filament supply, reducing material waste and making better use of leftover filament.

Intelligent Filament Monitoring
The AF-01 features 7 optical sensors that monitor filament position and movement. Three status indicators provide a quick overview of the operating status and warnings.
High-Torque Extruder
The AF-01 uses a dual-gear extruder with hardened, wear-resistant gears. Its 6.25:1 reduction ratio provides high torque and stable filament feeding, including during frequent filament loading and unloading operations.

Multi-Color Printing
The AF-01 can be used for multi-color printing workflows with compatible FDM printers. However, unlike the Creality CFS multi-material system, the filament must be cut manually when changing colors. The AF-01 is therefore primarily designed for automatic filament feeding and spool switching rather than fully automated multi-material management.
Easy Installation
The AF-01 is designed for straightforward integration. Installation involves connecting the filament connectors to the extruder adapters, attaching the PTFE tube to the output port and connecting the power supply. According to the product documentation, no complicated wiring or firmware modifications are required.
Compatible Printers
The AF-01 is compatible with a range of Creality FDM 3D printers, including K1, K1 Max, K1C, K1 SE, K2, K2 Pro, K2 Plus, K2 SE, Creality Hi, Ender-3 V3, Ender-3 V3 Plus, Ender-3 V3 SE and Ender-3 V3 KE. Always verify compatibility with the specific printer and required adapters before installation.
