Instructions could be clearer

The hardware is excellent, but setting up the water loop took some trial and error. Once running, it's fantastic.

Great performance but needs a pump

Works exactly as described. Just remember you need to buy a separate water pump and reservoir; it doesn't come in the kit.

Perfect for high-speed ABS printing

The water cooling keeps the heat creep away even when pushing 150mm/s. Installation was straightforward with the included fittings.

Good but heavy for some printers

It cools very well, but the added weight of the water lines caused ringing on my lightweight gantry. Might need tuning.

Solid build quality

The machining on the aluminum block is precise. No leaks after two weeks of continuous printing with PETG.

Essential for industrial filaments

We use this for printing carbon-fiber filled nylon. The constant temperature control prevents clogs effectively.

5 FAQ

Q: Can I use this with a 12V power supply?

A: Yes, the heater cartridge is dual voltage compatible and works efficiently with both 12V and 24V power supplies.

Q: How do I prevent leaks at the tube connections?

A: Ensure the tubes are cut perfectly straight and pushed firmly into the push-to-connect fittings until they stop. Tug gently to confirm they are seated.

Q: Does this kit include the water pump and radiator?

A: No, this kit includes only the hotend assembly, tubing, and fittings. You will need to source a compatible water pump and radiator separately.

Q: What type of coolant should I use?

A: Distilled water is recommended to prevent mineral buildup. You can also add a small amount of biocide if the system will run for extended periods.

Q: Is this compatible with 2.75mm filament?

A: This specific model is designed exclusively for 1.75mm filament. Using 2.75mm filament may cause jams and damage the extruder.
