Stepper Motor in 3D Printers

3D Stepper Motor 3D Printers

Stepper motors are an important part of 3D printers. They are used in a variety of applications depending on the type of printer. For example, 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.

Stepper motors are unique in that they can move to a known interval and then hold that position. Because they are a good motor to move an object to a repeatable position, they are often used in robotics and in printers.

Stepper motors come in a variety of sizes. The most popular sizes used in 3D printers are the NEMA 14, NEMA 17, NEMA 23, and NEMA 24. NEMA is a measurement standardized by the National Electrical Manufacturers Association (NEMA) and refers to the frame size of the motor. Just because a motor has a larger frame doesn’t mean it has more torque.
