Shape deformation of PLA '2079851475616104452 under rapid cooling
Fenómeno del problema
Rapidly cooled PLA products warp in shape.
Análisis de la causa
During rapid cooling, the temperature difference between inside and outside is large and shrinkage is inconsistent, causing warpage.
Solución
Balance the cooling rate, do not quench; increase mold temperature.
Conclusión clave
PLA cooling uniformity is crucial.
