PLA 3D Printing Moisture Absorption
문제 현상
PLA filament shows popping sounds, bubbles and rough surface during printing after the package is opened
원인 분석
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
해결 방법
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
핵심 요약
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
