PLA is a product derived from natural crops like corn, unlike other polymer plastics. It is eco-friendly and biodegradable. Almost all FDM 3D printers can print with PLA. As its melting point is low, PLA is very easy to print.

PLA+ is PLA that has been enhanced by adding modifiers during PLA synthesis.The mechanical properties (flexibility, strength, ductility, etc.) of PLA+ are superior. 3D printed models from PLA+ have a smoother surface and better appearance.
