J-Head Ml IV-B Pre-Assembled Hot End (Discountinued)

DISCOUNTINUED: We will no longer be selling the J-Head hot end.  If this is a part that you would like to continue using, it can be purchased here.

The J-Head Ml IV-B model is a pre-assembled hot end commonly used with RepRap and other 3D printers. J-Head Ml IV-B pre-assembled includes : 100k ohm thermistor and 24V 40 watt heater cartridge. This nozzle extrudes out of a 0.5mm orifice diameter.

Per our supplier, 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.)
