3D 3D 3D Printing Method base on the 3D Printer Bed

摘要

The present invention relates to an automatic monitoring device and a monitoring method of filament transfer in a 3D printer, the method having a filament presence/absence sensor at the front end of the feeder, an encoder wheel and an encoder for measuring the transfer distance and transfer speed of the filament to the feeder. A 3D printer comprising a sensor, comprising: a first process of determining whether a filament presence detection sensor state, a filament presence flag state, and a filament removal command are checked to determine whether a filament input operation or a filament removal operation is necessary; A second process of heating the heater nozzle while driving the motor and melting the filament to push it out of the nozzle while measuring the encoder data and checking the transfer distance and speed of the filament when the filament input operation starts; A third process of heating the heater nozzle while driving the motor to melt the filament and push it to the front end of the feeder while measuring the encoder data when the filament removal operation is started and checking the transfer distance and speed of the filament; It comprises. Accordingly, in order to inject the filament into the heater nozzle, the user simply takes a simple operation of pushing the filament up to the inlet, giving a separate key operation or computer command, waiting for the heater nozzle to heat up, or inconvenient to use both hands It provides the effect of removing and provides the effect of removing the difficulty of estimating the amount of pushing the filament to the heater nozzle.
