Product Description

H2 V2S

Dual Gear | Direct Drive | Cost-effective Choice

195g lightweight 

Support 270℃

Dual gear 7:1

Labor-saving level

The structure of H2 V2S is compact, neat and lightweight, which can greatly reduce the inertia of the motion axis.

Light & Compact

Light weight, Low inertia, better positional accuracy.

It was built with 6061 T6 aluminium alloy, screw tensioner and ingenious switch lever.

Exquisite Craftsmanship

6061 T6 aluminum alloy body ensures long-lasting performance even under extreme conditions.

With a gentle push, you can quickly import filament. With a pushback, you can quickly lock the position of the filament.

Easier Filament Feeding

Upgraded switch lever frees your hands when feeding.

H2 V2S is built with a quick dissipation structure.

Efficient Heat Dissipation

Heatsink design optimized to improve heat dissipation, prevent heat creep and ensure longer lifespan of extruder.

H2 V2S has a powerful extrusion system.

Powerful Extrusion System

Dual gear and a gear ratio of 7:1 for exceptional pushing force.

Use a screw to adjust the tightness of the filament.

Great for flexible filament

Adjust the screw tensioner to accommodate different drive gear tension and improve printing with flexible filament.

High-quality durable heatbreak, heating blocks, and nozzles to make it work within 270℃.

High-Temp Printing

Bi-metal heatbreak enables high-temp printing at 270℃ with silicone sock for insulation.

BIQU H2 V2S can be used to create models printed with a variety of filaments.

Perfect Compatibility

Compatible with numerous materials, ranging from PLA and ABS to TPU, Nylon and PETG.

The H2 V2S Complete Kit includes one pre-assembled extruder and other tools to set it on the 3d printer.

What's in the Box

BIQU H2 V2S Extruder.

Ordered to replace my Ender 3 extruder, plus i wanted to go down the direct drive route as I am running Klipper. I was amazed how small the H2 is. Installing the H2 took a while I designed a better mounting plate. I have been running my printer 24/7 with no problems. Hope to buy another H2 soon.

Solid upgrade - a big step up in performance

This was my first hot end replacement after upgrading almost everything else but the printer's frame. I am very glad I chose the H2 V2S.

While waiting for delivery I was able to adapt and print the parts I needed to attach it to my Voxel Aquila X2. In the end I replaced the Aquila X-carriage for a stock Ender 3 carriage as that gave me access to more proven starting designs for the mounting plate.

All the bundled electrical parts seem to be of quality, the the heater cartridge leads were already crimped which was nice to see. The H2 V2S mechanical design is beautiful and so compact, I was amazed at how small it was once it was in my hand. The manual gear operation is smooth it shouts quality. The filament release has a satisfying click. In operation it is silent with the occasional quiet click of retraction (when retraction is set to at 0.5mm @ 5mm/s - my bowden setting of 45mm/s makes it a bit chatty :) ).

I really like the consistent 3mm mounting holes all over the H2 V2S and its symmetric geometric design, it makes designing accessories easy. I've secured it to the backplate from the top and back to help minimise flexing of the PETG backplate. By the way, the dimensioned drawing has some missing y-plane dimensions for the nozzle - I want to redesign my cooling duct and this would really help.

I was initially concerned about the 35mm fan not cooling enough and making too much noise but I was very wrong. Even in my longest print so far (4hrs @ 240deg PETG) there has been no sign of over-heating and it really is virtually silent - well done BIQU! (I say that as someone who replaced all the stock fans on their printer so I can share the room with it). I've initially chosen a 5015 blower with a three pronged duct as a part cooler and that is the noisiest part of my printer now but it is still very acceptable and it gives good results up to 70-degree overhangs. Most of the noise comes from the blower's narrow ducts so I'll experiment with other designs.

My printer's cable runs are a bit longer than a stock Ender, another 20cm on all cables would have been great but the installation was straight forward. I rerouted cables to get enough length for the head to reach full z-height and still get to the far right x-axis. Initially frustrating but not a big deal in the end. I would have liked the stepper motor lead to be terminated with a locking connector (HS?).

With the BIQU H2 V2S I've only just begun pushing speed but already I've achieved 100mm/s on everything. There is more speed to be had, 200mm/s gives very acceptable results but I think I need to upgrade my part cooling. The 100mm/s benchy was my best ever, the 200mm benchy was way better than my printers's original 60mm/s. I've printed about a dozen things so far (in PLA and mostly PETG) not a single issue with the H2 VS2 and all came out with better quality than I am used to.
