PLA 3D Printing Nozzle Clogging
Problembeschreibung
Nozzle clogs during printing.
Ursachenanalyse
PLA softens too early in the throat or carbonizes; improper retraction also causes clogging.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Lösung
①Optimize heat dissipation to prevent throat softening; ②Control retraction parameters; ③Clean the nozzle; ④Dry the filament.; After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Troubleshoot nozzle clogging from heat dissipation and retraction.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
