Silent and efficient

Replaced my noisy fan-cooled hotend with this. The pump is whisper quiet, and the print quality improved immediately.

Solid upgrade for Voron users

Fits perfectly on my Voron 2.4. The thermal stability is noticeable. Deducted one star only because the tubing fittings were a bit tight.

Great performance, setup takes time

Performance is outstanding once running. Just be prepared to spend an hour setting up the pump and radiator loop initially.

Handles engineering materials like a champ

I print mostly PEEK and PEI now. This hotend maintains temperature consistency better than any air-cooled unit I have tried.

Worth the investment

Expensive compared to standard hotends, but the reliability during long prints justifies the cost. Zero clogs so far.

Perfect for high-speed printing

The water cooling keeps the heat break incredibly stable even at 400mm/s. No more heat creep issues with PLA or PETG.

5 FAQ

Q: What is the maximum safe operating temperature?

A: The hotend is designed to safely operate continuously up to 500°C, making it suitable for most high-temperature engineering filaments.

Q: Can I use this with abrasive filaments like Carbon Fiber?

A: Yes, but you must pair it with a hardened steel or ruby nozzle, as the standard brass nozzle included will wear down quickly with abrasive materials.

Q: Is this compatible with the Ender 3 stock motherboard?

A: Yes, it is electrically compatible, but you will need to modify the mount and add external water cooling components which require space planning.

Q: How often do I need to change the coolant water?

A: We recommend using distilled water and checking levels monthly. A full change is suggested every 6 months to prevent algae or mineral buildup.

Q: Does this come with the water pump and radiator?

A: No, this package includes only the hotend assembly. The water pump, radiator, and tubing must be purchased separately.
