Water-Cooled Premium Print Head for Modix Printers

Premium High Flow Water-Cooled Print Head Upgrade for Modix Printers

Most hotends are air-cooled, which means that they use a fan to blow air across a heatsink, ensuring that the heat used to melt your filament remains in the heater block and nozzle, and not further up the hotend where it can can cause filament jams due to heat creep. But what if your build chamber is already hot, so the air being used for cooling isn't going to be enough? For those scenarios, HartSmart Products has assembled the best-in-class extruder and water-cooled hotend parts for the best combination of high flow rate and high print quality, regardless of the air temperature inside your build chamber. We then customized it to work as a nearly drop-in replacement for standard Modix print heads. Add your own water cooling system to this printhead and you've got a system capable of producing high quality parts in any environment.

Comes Fully Assembled - includes the extruder and hotend already assembled with a custom print head mounting bracket and a stepper motor so you can quickly and easily swap out your existing print head.
