Upgraded stainless steel gears with high precision and wear resistance. Properly reduce the outer diameter of gears to effectively solve the problem of gear jamming and ensure smooth extrusion.
Titanium-copper alloy Throat
Upgraded titanium copper alloy throat, high temperature resistance, and good heat insulation. This pipe can be quickly removed from H2 V2.0, it would be more convenient to replace the pipe.
Streamlined heat dissipation design
Adopt streamline structure with cooling fan to achieve high speed heat dissipation. Ensure the high temperature airflow upward and away from the nozzle, which will maintain a good heat dissipation environment while the extruder is working.
Dual gear extrusion
Direct extrusion enables short path to feed in and fast speed to feed out. The direct extruder has more precise control of the feeding volume, making the return pumping more accurate. Also, it is easier to change filament.
Light weight extruder
The light weight of the H2 V2.0 extruder will reduce the changes in printer structure and printing accuracy caused by the weight of the extruder.
The complete H2 V2.0 kit includes extruder, fan, BIQU duck, other assembly cables and tools.

*Note: Only needs a model bracket, H2 V2.0 is suitable for almost all hot-selling 3D printers. Here are the files for B1, Artillery X1 Genius, Pedro Palacio, CR10-S Pro v2, Ender 3/3 V2, Ender 5, Ender 6, Anycubic Mega, CR-10 V2/V3, Creality CR-6
Light weight, compact in sitze and powerfull. The only flaw is the full metal heat break when using flexible filament, such as TPU 70A. There ist too much back pressure while printing. The filament gets stuck and pressed everywhere else than the filament path. The default version of the H2 should have a heat break with PTFE Liner, the high temp version a full metal heat break.
h2 v2s revo
Having not used it yet will give 4 stars for now and update once ive used it. Looks and feel it is surprisingly light but solidly built.
Overall having a good experience with this direct extruder. It's good that it now has the stepper motor connector on the top stock. Gears have a small amount of backlash and click when retracting, but this is very quiet and doesn't seem to cause any issues. One improvement I would suggest is including a ~30cm longer set of cables to reduce the hassle of installation on common size printers like the Ender 3.
