PLA is the most common printer filament used for hobby and small manufacturing. PLA is an excellent general-purpose 3D printer filament, especially when looking for durability in your prints.

While biodegradable, PLA has a relatively low glass transition temperature (typically between 111 and 145 °F). This makes it fairly unsuitable for high temperature applications. Even things like a hot car in the summer could cause parts to soften and deform. PLA is a little bit more brittle than ABS for 3D prototyping but it has some advantages as well.
