Standards Setter

Genuine J-Head™ hotends have been around for a while with the mounting groove now a standard in the industry. J-Head™ hotends have helped set the standard. 


Genuine J-Head™ hotends consistently print at lower temps due to the way they are constructed.








Please note:  The maximum operating temperature is 248 degrees Celsius as PEEK will soften at 250 degrees Celsius.  Due to many variables, affecting the accuracy of the temperature readings and settings, caution is recommended when extruding at temperatures approaching this limit.

(PLA will require a small fan to provide air-flow through the cooling vents milled in the sides of the nozzle holder.)

J-Head 10 Datasheet

  The following is a list of just some of the improvements made to the Genuine J-Head™ 10 hotend:


  • Extending from the mounting groove the hotend is over 13mm shorter than the Mk IV-B and earlier J-Head hot-ends.  This will increase the height of your print area.
  • Longer melt zone to reduce the temperature required for extrusion.
  • The top portion, of the melt zone, is insulated by the lower part of the PEEK nozzle holder.
  • The lower taper, on the PTFE liner, is no longer required.  As a result, the liner can be tighted considerably without fear of jamming the hot-end.



  • Internally, the filament path is identical to that of an already proven design.

  • The design is simple as the number of custom machined parts is kept to a minimum.

  • The PTFE is not stressed nor used to provide support.

  • This reduces a point of failure that is part of other hotend designs.

  • Heat transmission is improved as there is no thermal junction where a separate heater screws onto the nozzle.
