Water-Cooled Technology

The big difference between the Titan Aero and the Titan Aqua is the cooling technology. The Aero uses a fan to air-cool the heat sink while the Aqua uses the power of water-cooled technology. The water-cooling is much quieter since the fan and radiator are larger and separate from the hotend. This is perfect for use in warm chambers where air-cooling is less effective, thus improving the thermal performance and print consistency of the Titan Aqua.

Warm coolant is passed through an external radiator for cooling

Titan Aero Upgraded

The Titan Aqua has all the same features that makes the Titan Aero an excellent tool head, including the idler mechanism, easy filament change, sharp-toothed custom-machined hobb, and precision 3:1 gearing ratio. The new water cooling technology along with other optional upgrades such as the plated copper blocks and nozzles further improve its performance. Not only is the print head less bulky, it has less vibration which ultimately increases print quality.

Complete the Titan Aqua package

This item - the Titan Aqua hotend and extruder - does not include the tubing, fan, pump, or radiator required for a complete liquid-cooled package. We have the E3D Water Cooling Kit available as an add-on to complete the setup here. Or, if you prefer to build a different system with your own components feel free - the only compatibility to keep in mind are the adapters that accept 4mm tubing on the Titan Aqua extruder.
