Environmental aging of PLA during long-term use
Fenómeno del problema
PLA properties gradually deteriorate during the service period (several months to 2 years).
Análisis de la causa
Slow hydrolysis and thermal oxidation superimpose, causing mechanical properties to decline.
Solución
Design corresponding safety factors and service life evaluation.
Conclusión clave
PLA aging during service period is a limiting factor.
