The FL300M features a high performance & precision motion system, coupled with Fuselab`s unique rotary extruder design
Traditional Fused Filament Fabrication (FFF) extruders feed the filament into the melt zone with 1 or 2 drive gears, thereby only providing 1-2 points of contact between the drive system and the filament. At higher speeds or extrusion forces this can result in slipping and subsequent under-extrusion. The rotary extruder consists of 3 drive rollers each offering multiple points of contact, significantly increasing engagement between the drive mechanism and the filament.
This is particularly beneficial for 3D printing with metal powder based filaments. These filaments are more fragile due to their high metal powder and low binder content, and the distributed contact of the rotary extruder minimizes the risk of filament failure. In addition, the non-slip characteristic of the extruder eliminates under-extrusion, resulting in high solidity, which is especially desirable in metal parts.
The multi-contact rotary extruder transfers the extrusion force over an increased number of contact points, reducing filament stress and minimizing the risk of filament failure.
The increased contact between extruder and filament prevents filament slip and the requested extrusion quantity is always achieved. As a result, the rotary extruder ensures high part solidity for metal parts and repeatable results.
Output efficiency of rotary extruder vs convention extruder, the rotary extruder delivered 100% of requested flow up to filament tensile strength limit
Higher printing speeds require higher extrusion forces. Our testing has demonstrated that extruder slip under high speed- high force conditions has been eliminated, removing extruder performance as a system limitation.
Designed for simplicity, the extruder head can be removed in seconds without disconnecting wires, thanks to durable pogo pin connectors. Maintain or upgrade your printer with ease.
