Patent ID: 11000996

Abstract:
A secure extruder device includes a material delivery channel, a nozzle part, a parameter part, a thermal-control part, a material auto-destruction module and/or a parameter auto-destruction module. The material delivery channel is assembled with an extrusion part. The nozzle part is connected to the material delivery channel for ejecting material in the material delivery channel out. The parameter part provides parameters for a printing task to a microcontroller. The thermal-control part heats the nozzle part according to the parameters for the printing task. The material auto-destruction module destroys the material delivery channel after the printing task is completed. The parameter auto-destruction module destroys the parameters for the printing task after the printing task is completed. The microcontroller controls the extrusion part based on the parameters for the printing task so that the extrusion part delivers the material disposed inside the material delivery channel to the nozzle part.
