In all likelihood then, PLA does degrade when outside, but the rapid biodegradation often discussed requires a specific set of conditions, which are unlikely to naturally occur. As a side note, PLA is referenced as considerably UV resistant.

UV resistance conclusions PLA and acrylic had similar burst strength loss. PET had the worst in the study: PLA (-21.3%) PET (-47.4%) Acrylic (-22.2%) The PLA sample had about an 8% molecular weight loss over the 1000 hour exposure time period. This is 0.7% outside the error of the instrument. The acrylic had the greatest change in color, as

I guess a knob thing will to quite well outdoors, but a hook will not. ABS will see surface degradation from UV, but will hold it's structural integrity much longer. UV radiation attacks all types of polymers, but a few (such as acrylonitriles and methyl methacrylates) show better UV resistance than most. It can cause color change and degradation of physical properties, especially in: UV resistance. Unlike other synthetic fibers, PLA does not absorb light in the visible region of the spectrum; this leads to very low strength loss compared to petroleum-based fibers when exposed to ultraviolet light.

Of all In all likelihood then, PLA does degrade when outside, but the rapid biodegradation often discussed requires a specific set of conditions, which are unlikely to naturally occur.

Les plastiques résistants au climat sont intrinsèquement résistant aux UV et ne changent d'aspect.Ils ne présentent pas non plus de modifications des propriétés mécaniques. La résistance aux UV des plastiques est obtenue par l’utilisation d’additifs tels que les stabilisateurs UV, le noir de carbone, ou des revêtements de surface (peinture ou métallisation).

This post compares PLA vs ABS and now nylon, and then details how one of these thermoplastics has been augmented to serve a wider range of manufacturing applications. 1999-11-02 Polylactic Acid Properties, Production, Price, Market and Uses. PLA global trade balance is negative. Since 2011 the import of PLA is more than the exports. The import of PLA in 2016 was worth of US$ 204.79mn while export was US$ 181.55mn.The exports have been increasing from 2011 onwards while an import shows a UV radiation from sunlight is particularly effective in outdoor applications without protection. Main effects on polymers exposed to UV. All types of UV can have a photochemical effect within the structure of the polymers, which can be beneficial or can cause some type of degradation in the material.

The optimal PP/PLA ratio of 80/20 is used to have better I thought that PLA has a low UV resistance, because I only print prusa/prusament PLA and the description tells me that PLA has a low UV resistance. A user in a german facebook group does not share my opinion and tells me, that PLA is highly UV resistant. So, I searched and googled Various sources say, that PLA is high/highly UV resistant.

A = No Attack, possibly slight absorption. Negligible effect on mechanical properties. B = Slight attack by absorption. Some swelling and a small reduction in mechanical likely.
