Water-Cooling: The next step in 3D printing - for use with E3D Titan Aqua

We've reached the limits of what air-cooled 3D printing can do. This kit contains everything you need to upgrade your printer for water-cooling.

Fan Cooling

We've reached the limits of what's possible with HotEnd fans mounted on the print-head. This combination fan and radiator is much larger and more efficient than what's achievable with air-cooling systems. This also makes it quieter, and very low-vibration.

Easy to use

By limiting the number of parts, we've made this kit easier to use than any water-cooling system we've seen for 3D printing before. The parts fit together snugly, and have been designed for neat and ergonomic building.


Our kit design is based on standard computer cooling components, allowing users to adapt and expand on the kit as they wish, to cool additional HotEnds or even motors and extruders inside the print envelope. With 8mm outer diameter/4mm inner diameter silicone tubing, it's also compatible with most water cooling systems.


This kit can be used with any water-based coolant from Purified H2O to popular UV-toned brands.

Warnings: Not suitable for use with plain tap water! This kit can also be used with 24V printers, but you will require a DC-DC converter.
