Dimensional change of PLA products during use
Problem Phenomenon
The dimensions of PLA products change slightly after a period of use at room temperature.
Cause Analysis
Post-crystallization and slow release of internal stress of PLA cause dimensional changes.
Solution
Fully anneal to stabilize the dimensions; perform environmental conditioning before use.
Key Takeaway
The dimensional change of PLA is the combined consequence of crystallization and stress.
