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.

Cold End

The most important aspect for performance in your 3D printer is the Cold End. It drives the filament and applies force, so it will extrude the plastic onto a 3D print. Consistency and reliability are keywords here for making the best 3D prints. There are various solutions to drive filament, from simple direct drive systems to geared bowden system. Whatever you choose, we have the best component to build your extruder as well as pre-build extruders.
