Shape deformation of PLA '2079851475616104452 under rapid cooling
Problem Phenomenon
Rapidly cooled PLA products warp in shape.
Cause Analysis
During rapid cooling, the temperature difference between inside and outside is large and shrinkage is inconsistent, causing warpage.
Solution
Balance the cooling rate, do not quench; increase mold temperature.
Key Takeaway
PLA cooling uniformity is crucial.
