1set J-head Hotend for E3D Long-Distance Filament Bowden extruder with Cartridge heater & PTFE tube

(Please tell us which filament you want,1.75mm or 3.0mm and tell us what size the nozzle you want,0.2mm 0.3mm 0.4mm,or we will ship the 1.75mm filament,0.3mm nozzle as default)

This all-metal J-Head Hot End has faster controlled motion, less shaking of your machine, less energy use and importantly: faster printing! Normally the mechanism that drives the filament into the hot end (where it melts) is directly on top of the extruder. This creates problems of balance and oscillations with faster motion which you can see in your printing results and hear and feel when your machine is shaking.

If the filament drive mechanism is placed on a non-moving part of the 3D printer, it can be pushed into a tube. PTFE (Teflon) is useful because it is slippery: it has little friction with the plastic.This limits wear and loss of energy. The tube’s other end is connected to the extruder’s hot-end.

Feature:

All metal enables working with Polycarbonate up to 300 degrees Celsius and with future materials that require higher working temperatures beyond those supported by plastic extruders and hot end.

Tested with PLA, ABS, polycarbonate, nylon and PVA.

The inner diameter of the bowden feed mouth is 4mm to print with 1.75mm filament,and 6mm to print with 3mm filament.

This long-distance J-Head hot end allow it apart from extruder to printer.
