Polylactic acid is chemical compound that one of the most commonly-used 3D printer types of filament is built from. PLA is made from natural materials such as corn starch or sugarcane and thus makes it fully biodegradable. Fun fact: It's even degraded by some bacteria! The environment-friendly aspect of PLA grows even bigger due to fact it can be recycled easily. As a relatively easy material to work with PLA allows newcommers great start to 3D printing adventure and to unleash their creativity. More advanced 3D printing fans will be pleased with its good print quality which makes PLA a great material for making complex, high resolution 3D models. 3D printer filaments based on PLA are pigmented variously so - in a nutshell - everyone will find something suitable.
