Notes on Extruder Design

  • If we assume that metal takes heat out much faster than air - then the heat break should be metal-cooled, not air-cooled. This is found in E3D Titan Aero - where metal sucks the heat from the heater to provide a short transition zone. This is not found in the J-Head, where there is a longer transition zone?
