If you're printing items that will live outside, like garden planters or car mounts, using standard PLA filament is a mistake. Under hot summer sunlight, PLA will warp and degrade within weeks due to low heat resistance.

Key Findings & Deep Dive
For outdoor durability, PETG is the easiest budget option, offering solid UV resistance and a heat deflection temperature of 170°F. However, for maximum industrial durability, ASA is the gold standard because it resists UV fading and weathering.
Verdict & Recommendation
Printing ASA requires a heated build plate and an enclosed printer to prevent warping and fume buildup. Choose the filament type that matches your project requirements.
