GeTech MK4 MKIV J-Head Hot End 0.35mm/0.5mm nozzle 3mm filamnet + cable For 3D Printer

   
Items Description

Description:

Removed the heat sink and added a series of vents to provide cooling. To reduce weight, an aluminum nozzle is used.

This J-Head Hot End is designed based on other nozzle. It's very simple by reducing the number of custom machined parts to a bare minimum. The J-Head Hot End can easily and well interface with the most popular RepRap extruders.

The filament path is same with the one of an already proven design, it can be used to print reliably with both ABS and PLA. If using PLA, it requires a small fan to provide air-flow through the cooling vents milled in the sides of the nozzle holder. Besides, the Hot End has another two advantages. Heat transmission is more efficiency as there is no thermal junction where a separate heater screws onto the nozzle. And a resistor is used as a heater. There is no need to wrap nichrome wire or to bake a heater core.
