PLA filament is commonly used to create complex parts and details, including corners, sharp parts, and extremely small pieces. This is why it is frequently used for creating architectural mockups, aesthetic and concept models, and casting molds. Depending on the quality settings of the print, layers might still be visible after every print.
In general, this material is very popular for prototyping. Because it is at a lower price point than most other filaments, manufacturers and developers are able to test out different prototypes without a huge investment. It is also biodegradable, which means you can lower your impact on the environment.
