The Bowden principle
The Bowden cable lets you reduce the moving mass of the extruder and thus allowing 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.
The concept of using a Bowden cable as guide was suggested and pioneered by Ed Sells.

The main advantages
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.


Features
It is assembled with Cartridge Wire  and 100K NTC thermistor.
The inner diameter of the bowden feed mouth is 4mm to print with 1.75mm filament,and 6mm to print with 3mm filament.

    What is the voltage of the heating element?

    • rita xiang | 08/22/2016

      it is 12V 40W you can check it here http://www.geeetech.com/12v-40w-cartridge-wire-heater-heating-wire-p-804.html

    Hi, does this come with a cooling fan? It states that it does but it's not in the picture. Thanks.

    • Quentin Qiu | 03/08/2016

      Sorry for bringing you confusion, the cooling fan doesn't come with the product. You need add the fan yourself.


  • Anthony Martin | 04/15/2015

    does the hotend include the heater and thermistor?
