PLA is a plant-based, biodegradable plastic. Its popularity in 3D printing stems from its incredible printability and versatility. 

Printing and Performance

PLA is one of the easiest materials to print. Temperatures are flexible and warping is minimal. For this exact reason, many people have only ever printed PLA.

PLA is also known for its print quality. It has the best detail reproduction of the common 3D printing filaments, making it ideal for models where aesthetics are important. Easily taking pigments, PLA is also available in all sorts of vibrant colors and blends.

For practical applications, PLA’s strength is also surprisingly ample for most light prototypes and models. Unless your application requires significant load-bearing and durability, PLA should serve you well.

External Factors

PLA is also preferred for those looking for a more environmentally-friendly plastic. PLA is based on plant matter, making it biodegradable (given some time with microorganisms and humidity). Its biodegradability isn’t enough to degrade printed parts in normal room environments, but it will allow them to decompose, if necessary.
