BIQU Water Cooling Kit

A Veteran Maker’s workshop is the closest thing to your modern-day mad scientist lab, where at least one 3D printer is lovingly modified to its fullest potential. If you enjoy keeping up with new 3D printing innovations as we do, you may have already spotted the interesting concept of water cooling your hotend assembly as a replacement for high-speed fans. The BIQU Water Cooling Kit offers extreme efficiency for cooling which allows for incredibly high 500°C print temperatures and shows off a stunning aesthetic with near-silent operation.

The importance of cooling a “hot”end assembly might seem contradictory, but all hotend assemblies in fact contain a cold and a hot end which must maintain balance for the 3D printer to function. The heater block, heat break and nozzle make up the true hotend where your 3D filament is melted and extruded through the nozzle. Without an effective cooling system for the rest of the hotend assembly, heat may travel from this melt zone and affect other parts of your assembly. This is called “heat creep” and may result in your filament melting too early within the assembly, building up and then jamming the extruder entirely. Standard stock 3D printers combat heat creep using cooling fans, but these small axial fans can only go so fast and really feel the wear as you kick up the printing temperature past 270°C. Logically, Makers have compensated with stronger fans or even dual fans to maintain this temperature balance. While these solutions are certainly effective, they simply cannot compare to the advantages of water cooling which accommodates printing up to 500°C!

This awesome-looking BIQU Water Cooling Kit consists of the pump, radiator, and fan mounted on an aluminium stand that separately sits beside your 3D printer or just outside the printer enclosure. Water coolant pumps at a fantastic 500L/H flow rate into your hotend to cool down the heatsink before cycling back through the radiator where a 120mm fan spins away to keep everything frosty. The Water Cooling Kit is designed to pair up with the H2O Direct Drive Extruder itself, a highly specialised BIQU H2 extruder and hotend that is modified with full-metal quality components for smooth high precision printing at high temperatures. While not included with this kit, the BIQU H2O DDS Extruder effectively cools your hotend by pumping in the fresh coolant with no extra weight pressing down the print head, which was a downfall of many other brand designs. Brackets and connectors are included for neatly running the tubing. The Water Cooling Kit really shows its merits when printing advanced and sensitive exotic 3D filaments such as Nylon or Carbon Fibre which require extreme temperatures and care. The result is impressive heat dissipation while operating at a low noise level of 25DB. So, if you are interested in water cooling your 3D printer for high performance worthy of engineer-grade 3D filaments or admittedly enjoy the mad-lab look of bubbling pipes, the BIQU Water Cooling Kit is one of the most unique and effective printer upgrades we have to offer.

Important Note: Please do not use tap water with your BIQU Water Cooling Kit, as you will risk degrading the water system and damaging your printer. We highly recommend using a quality liquid coolant which is designed for chemical resistance and features a low freezing temperature for effective cooling.

Additional Note: This Cooling Kit does not include the BIQU H20 Extruder. However you may purchase it separately or pick up a Phateus Dragon Water Hotend to install with this awesome 3D printer upgrade.

Although many people may not quite recognise the name, BIQU is a fantastic brand that originated as BigTreeTech, and began their journey in the 3D Printing world by creating motherboards and other electronics that were made to enhance the functionality, ease of use and overall capabilities of other 3D Printers. However, after gaining a firm popularity as some the leaders in 3D Upgrades, they have also now branched off and created BIQU, a brand dedicated to creating entire 3D Printers for hobbyists like us.

Compared to many of the brands on the market, what we particularly love about BIQU is the way that their models come fully equipped with all of the exciting BigTreeTech controller boards, stepper drivers and other awesome components that are typically installed into other 3D Printers as powerful upgrades. These include the popular SKR motherboards, the BTT TMC Drivers, BTT TFT displays and other minor (but still valuable) upgrades that are often installed on Creality 3D Printers, but since these “upgrades” come stock on BIQU 3D Printers, you can enjoy even more reliable operations and functionality due to the fact that their machines are built specifically with their own boards and components in mind. This has resulted in BIQU creating some of the leading 3D Printers on the market, which don’t need any upgrades or improvements to match the quality of leading brands, and with many of the BIQU models actually surpassing the quality and capabilities of most other Hobbyist 3D Printers on the market.

If you love the idea of upgrading 3D Printers with all kinds of fun and functional upgrades, but aren’t too interested in getting a basic model that you have to actually upgrade yourself, the BIQU range of 3D Printers is the answer, bringing excellent quality coupled with all of the current best features available to 3D Makers.
