A simple-to-use 3D printing pen and its control method

Abstract

This invention discloses a simple-to-operate 3D printing pen and its control method. The control method for a simple-to-operate 3D printing pen is characterized by the following steps: S1, when the controller receives a first signal and a second signal sequentially within a preset time, the controller drives the motor to rotate in a first direction, allowing the motor to drive the 3D printing filament towards the nozzle via a drive device. The 3D printing filament is then extruded from the nozzle after being heated by the nozzle; S2, when the controller receives a second signal and a first signal sequentially within a preset time, the controller drives the motor to rotate in a second direction, allowing the motor to drive the 3D printing filament away from the nozzle via a drive device. The simple-to-operate 3D printing pen is equipped with a first signal acquisition unit and a second signal acquisition unit that continuously acquire the first and second signals. The beneficial effect of this invention is that the rotation direction of the motor can be controlled by the sliding direction, thus achieving control over extrusion or retraction.
