The extruder section contains everything for getting filament through your 3D printer. This includes parts for driving the filament, guiding the filament and melting it. You have the option to use a direct drive system in which the hot-end is directly connected to the cold-end, but you may also opt for a bowden system in which the filament is guided through a PTFE tube between cold-end and hot-end. Heaters, thermistors and controller electronics you will find in the temperature control section.
The available hot-ends we offer include the older v5 system which is still used in some systems, the J Head-compatible hot-end which has bee in use for quite some time and the very reliable E3D hot-ends.
