3D Printer Extruders
There are two main types of 3D printer extruder: direct and bowden extruders.
Direct extruders are attached to the hot end minimizes the distance the filament needs to travel.
Bowden extruders are not directly attached to the hot end. They have a PTFE tube which connects the extruder to the hot end.
There are also dual extruder 3D printers, printers which use two extruders rather than just one.
3D Printer extruder is responsible for how much and at what speed your 3D printer pushes filament into the hotend...
