J Head Hot End Kit

Original, Made by the Inventor
Not Chinese Knock-Off

For 1.75 mm or 3.0 mm Filament

(May be tan or black)

DIY 3D Printer Hotend, Resistors DIY 3D Printer Hotend, Resistors
  • 5.6 Ohm Resistor
  • 100K Thermistor
    Thermistor specs
  • Teflon Tubing for
    Resistor and
  • Lightweight. Prints fast

  • Prints reliably with both ABS and PLA.
    (PLA may require a small fan to
    provide air-flow through the
    cooling vents which are milled
    in the sides of the nozzle holder.)

  • Easily interfaces with the most popular
    RepRap extruders, such as
    Wade's Extuder and Greg Frost's
    Hinged Accessible Extruder

  • Simple design. Number of custom
    machined parts is kept to a minimum.

  • Resistor is used as a heater. No need to
    wrap nichrome wire or to bake a
    heater core.

  • Heat transmission is improved because
    there is no thermal junction where
    a separate heater would screw
    onto the nozzle.

  • .5 mm

    72 to 152 Watts
    For 12 or 24 volt printers

    We provide you a special option not normally found, a chance to pick the resistance (power level) you desire for your printer.

    We have measured and sorted these MK2 hotbeds by their room temperature resistance which gives us a general idea of the wattage of each.

    These MK2 Hotbeds can be used for both 12 and 24 volt systems. There are two heating circuits on each board. For 12 volt systems, you will run the heating elements in parallel, while 24v dc systems will be wired in series. Instructions are clearly marked on each board.

    Which heatbed should I get?

    We have heard of some customers having trouble with their printer when the heatbed turns on. Usually this is because the heat bed is using more power than the power supply can reliably provide.

    If you have enough power, we would suggest the lower ohm heat beds, as they will heat up more quickly. If you have a less capable power supply, pick a heat bed that is well within its power specs.

    On all of these beds, we like to use a heat spreader like a thin sheet of aluminum between the hotbed and the printing surface.

    Lower Wattage

    We've found that the lower wattage beds struggle to hold the higher temperatures. Insulating the bottom of the board, and possibly covering the unused sections of the top surface can help these boards heat up faster and hold temperature better, especially in the presence of a cooling fan.
