The working principle of a 3D printer is to use Fused Deposition Modeling technique (FDM), it melts hot-melt materials and then hot material is sent to a sprayer.
The sprayer moves with pre-programmed path, to build wanted shape.
There are at least 3 motors is needed to move 3 dimensions(X,Y,Z axis).
With certain order from the controller, a stepper motor is moving certain distance, with certain speed,
In general, hybrid stepper motors with lead screw is used on a 3D printer.
