Polylactic acid (PLA) is a high biodegradable polymer material which is made of biomass starch and polymerized by high technology. PLA has good biodegradation property. It can be fully degraded by microorganism in the soil within two years, and the generated CO2and H2O have no pollution to the environment. Meanwhile, PLA has good machining property, it can do most of the jobs synthetic plastic do. PLA products can be fully degraded by microorganism and used as compost. They have no harm to the environment and can be regenerated. Above all, PLA is an environment-friendly material. Creatbot PLA 3d filament is a kind of filament researched by ourselves, better character than you buy in market.
