PLA is short for Polylactic Acid, a thermoplastic polymer that is derived from renewable resources, more specifically from corn starch or sugar cane. This sets the material apart from other commonly used plastics, which are procured through the distillation and polymerization of nonrenewable petroleum reserves. Since PLA filament is a biodegradable product, it tends to naturally break down in about three to six months. Other thermoplastic materials can take up to a thousand years to decompose, making PLA much more environmentally-friendly. Its temperature range from about 190C to 220°C. PLA material has been thrusted into the spotlight by the rise of FDM 3D printing. PLA filament is available in a wide variety of colors and blends, and innovative PLA-based materials seem to be constantly hitting the market.
