PLA information PLA, also known as polylactide, refers to the polyester polymer obtained by polymerization of lactic acid as the main raw material, usually using renewable plant resources (such as corn, cassava, etc.) made of starch as raw material. It is a new type of renewable biodegradable material. PLA material characteristics The raw materials are renewable and relatively easy to obtain even if used as 3D printing materials, which can be used for large-scale production; The PLA has good thermal stability and solvent resistance. The processing temperature of PLA is between 170 ℃ and 230℃, and the finished product has good heat resistance. Good permeability and transparency luster, can be processed by extrusion, spinning, biaxial stretching, injection blow molding and other ways, tensile and bending modulus can be comparable to the traditional plastic resin; High biocompatibility. The monomer material of PLA, L-lactic acid, is an endogenous active substance in human body. Therefore, the finished product printed by 3D printing material PLA is non-toxic to human body and can be absorbed by human body. It has good degradability. Different from the degradation methods of other 3D printing materials, PLA is embedded in the soil and completely degraded by microorganisms in nature under specific conditions to generate carbon dioxide and water. The carbon dioxide generated directly enters the soil organic matter or is absorbed by plants instead of being discharged into the air, which is recognized as an environmentally friendly material. Application of PLA materials Due to the good mechanical and physical properties of PLA material, PLA material is widely used, including various food containers, packaged food, fast food lunch boxes, etc.  At the same time, with its advantages in compatibility and degradability, PLA can also play a large role in the medical field, which can be made into medical tissue skeleton material and medical carrier for human body. In addition to its excellent tensile strength and extensibility, PLA can be produced by various common processing methods, such as melt extrusion molding, injection molding, blow film molding, foam molding and vacuum molding.
