Problems solved by technology
[0002] Existing fused lamination 3D printer guide wire nozzle devices are relatively complex, including guide wire mechanism, heating extrusion mechanism, forced heat dissipation mechanism, and the forced heat dissipation mechanism is mainly to prevent the temperature rise of the drive motor from being too high due to the influence of the heating extrusion mechanism However, affecting its normal operation, the structure of the forced heat dissipation mechanism is complicated. The configuration of the forced heat dissipation mechanism not only increases the cost and increases the weight of the nozzle device, but also greatly increases the vibration of the entire mechanism, thus affecting the processing accuracy and speed of the nozzle.
