After 6 or more months, PLA Filaments become brittle and break easy. This make the filament not suitable for use. In our observation we found it happens irrespective of your region/climate or manufacture. Only the time may wary based on atmospheric parameters of the place where the filaments are stored. The main reason for brittleness of filament is due to moisture absorption. ABS, PLA, and other common filament materials are mildly hygroscopic, so they will readily absorb moisture from the air.
