PLA is a thermoplastic polyester biopolymer, It is the most commonly used filament in FDM 3D printers for its ease of use and a wide range of applications, especially those not mechanically or thermally demanding. It is formed by chemical conversion of corn into dextrose, then the dextrose is fermented into lactic acid seed, then polymerized into polylactic acid PLA biopolymer has similar properties to polypropylene (PP) and Polyethylene (PE)
