3D printer stepper motors are important parts of 3D printers. They are used in a variety of applications depending on the type of printer. For example, 3D printer stepper motors are used to move the extruder or the build platform alone the x, y, and z axis. The extruder assembly also has a Stepper Motor used to pull the filament into the extruder.
