Poor weather resistance of PLA, outdoor decomposition
Problem Phenomenon
PLA embrittles and decomposes after 1-3 months of outdoor use.
Cause Analysis
The combined action of outdoor ultraviolet rays, moisture, and temperature causes PLA to degrade rapidly.
Solution
Restrict outdoor use; if outdoor use is necessary, a composite light-resistant and waterproof protective layer is required.
Key Takeaway
PLA is not suitable for long-term outdoor use.
