"PLA is an acronym used to describe polylactic acid.
It is made of natural fibres and is 100% bio-degradable. It can be completely decomposed in a compost heap making it one of the most sustainable and environmentally friendly 3D filament polymers available. Your obsolete prints can be used to fertilise your lawn, not clog up a landfill.
It expels far fewer UFCs (Ultra fine particles) than ABS filament. This makes it the most suitable 3d filament polymer for indoor home use. Due to its natural starch composition, it produces a pleasant, sweet smell when extruding.
PLA is far less prone to warping than ABS filament. This makes it a practical solution for 3D printers that do and that don’t have a heated bed."
