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 andimportantly: 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.
