PLA 3D Printing Moisture Absorption
Fenómeno del problema
PLA filament shows popping sounds, bubbles and rough surface during printing after the package is opened
Análisis de la causa
After PLA filament absorbs moisture, the moisture vaporizes during printing, causing popping sounds at the nozzle, extrusion bubbles and rough surface; the mechanical properties of moisture-affected filament also decline; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Store the filament sealed with desiccant; ②Dry moisture-affected filament at 50-60℃ for 4-6 hours; ③Control the ambient humidity of the printing room; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Moisture prevention is the top priority in PLA filament management; sealed storage plus drying of moisture-affected filament, and the printing quality immediately shows the difference; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
