Mellow NF-Sunrise V1.2 Dual Drive Extruder – Ender 3, Voron, Prusa
Mellow NF-Sunrise V1.2 Dual Drive Extruder – Lightweight Precision Upgrade
Take your 3D printing to the next level with the Mellow NF-Sunrise V1.2 Dual Drive Extruder — a high-performance, direct-drive extruder engineered for users who demand precision, reliability, and speed. Featuring a 5:1 transmission ratio and CNC-machined hardened extrusion gears, the NF-Sunrise delivers powerful, consistent filament feeding while dramatically reducing clogging and print failures.
Made in Mainland China.
What's New in V1.2?
Version 1.2 incorporates customer-driven improvements: the distance between the extrusion teeth has been recalibrated, and the interior geometry of the extruder body has been optimised to increase extrusion force for even more reliable filament control.
Key Features
- 5:1 Transmission Ratio – Ultra-short filament path from gear to nozzle for responsive, precise extrusion with minimal lag.
- Refined Filament Channel – Fine-tuned inner filament bore ensures ultra-smooth filament flow, reducing resistance and jams.
- Lightweight Aluminium Body – Hollowed-out aluminium construction strips unnecessary weight while maintaining structural rigidity and excellent motor heat dissipation.
- Customised LDO 36mm High-Temp Motor – Runs cooler than standard motors while delivering ample torque; motor current rated at 1.2A.
- CNC High-Precision Extrusion Gears – Machined to tight tolerances for consistent bite and feed accuracy every print.
- Easy Filament Release – Redesigned filament-release lever makes swapping or clearing filament fast and effortless.
- Dual Mounting Options – Direct bolt-on compatibility with Ender series printers, plus triangular bracket mounting for Voron, BLV, and other custom builds.
- 16 Micro-Steps / 679 Steps per mm – Fine micro-stepping for high-resolution extrusion control.
- 1.75mm Filament Compatible – Works with the most widely used FDM filament diameter.

Frequently Asked Questions
Q: Is the Mellow NF-Sunrise V1.2 extruder compatible with Creality Ender 3 V2?
A: Yes. The NF-Sunrise V1.2 dual drive extruder is fully compatible with the Creality Ender 3, Ender 3 V2, and Aquila printers. It features a direct bolt-on mounting option for Ender series machines, making the upgrade straightforward without requiring additional brackets.
Q: What filament diameter does the NF-Sunrise V1.2 support?
A: The Mellow NF-Sunrise V1.2 extruder is designed for 1.75mm diameter filament, which is the most widely used size in FDM desktop 3D printing. It is not designed for 2.85mm or 3mm filament.
Q: What is the advantage of a 5:1 transmission ratio in this extruder?
A: The 5:1 gear ratio multiplies the stepper motor's torque five-fold at the extrusion gear, enabling much stronger and more precise filament grip. This minimises slippage, reduces under-extrusion, and allows the extruder to maintain consistent filament feed even at higher print speeds — particularly beneficial for flexible or high-flow filaments.
Q: Does assembly require special tools or technical experience?
A: Assembly is required and is best suited to users with intermediate 3D printer modding experience. Basic tools such as hex/Allen keys and a screwdriver are sufficient. Mellow provides documentation, and the community around Ender 3, Voron, and BLV builds offers abundant guides to assist with installation.
