Storage Management of PLA Products
Problem Phenomenon
Performance changes of stored material.
Cause Analysis
PLA absorbs moisture and also degrades slowly; storage conditions affect processability.; 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
Solution
①Store in sealed aluminum foil bags; ②Control temperature and humidity; ③First-in-first-out with short cycle; ④Test before use.; After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PLA storage period management is strict; sealing and turnover are the keys.; 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
