Quick Overview

J-Head Mk IV-B Hot End .35 Nozzle for 3mm filament 



This hot-end is a combination of ideas from other nozzle designs combined with a goal to reduce the number of custom machined parts to a bare minimum.  The J-Head Mk IV-B has been proven to print reliably with both ABS and PLA.  (PLA will require a small fan to provide air-flow through the cooling vents milled in the sides of the nozzle holder.)


This hot-end easily interfaces with the most popular RepRap extruders, including Wade's Extuder, Greg Frost's Hinged Accessible Extruder, etc.




Quantities over 5 pieces will come unassembled.

    J-Head Mk IV-B Hot End for 3mm filament 

    This hot-end is a combination of ideas from other nozzle designs combined with a goal to reduce the number of custom machined parts to a bare minimum.  The J-Head Mk IV-B has been proven to print reliably with both ABS and PLA.  (PLA will require a small fan to provide air-flow through the cooling vents milled in the sides of the nozzle holder.)

    This hot-end easily interfaces with the most popular RepRap extruders, including Wade's Extuder, Greg Frost's Hinged Accessible Extruder, etc.

    The J-head will print both PLA and ABS and will run upto 240c (ABS prints well at 225c)

    Advantages
       - 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.
       - If necessary, the PTFE liner can be replaced by using an off-the-shelf piece of PTFE tubing.
       - The PTFE is not stressed nor used to provide support. This reduces a point of failure that is part of other designs.
       - A resistor is used as a heater. There is no need to wrap nichrome wire or to bake a heater core.
       - Heat transmission is improved as there is no thermal junction where a separate heater screws onto the nozzle.
