PLA is the most widely used plastic filament material in 3D printing. Its low melting point, high strength, low thermal expansion, good layer adhesion, and high heat resistance when annealed make it an ideal material for this purpose. Visa mer Polylactic acid, also known as poly(lactic acid) poly, lactic, acid or polylactide (PLA), is a thermoplastic polyester with backbone formula (C 3H 4O 2) n or [–C(CH 3)HC(=O)O–] n, formally obtained by condensation Visa mer PLA objects can be fabricated by 3D printing, casting, injection moulding, extrusion, machining, and solvent welding. PLA is used as a feedstock material in desktop fused filament fabrication by 3D printers, such as RepRap printers. PLA can be Visa mer PLA is degraded abiotically by three mechanisms: 1. Hydrolysis: The ester groups of the main chain are cleaved, thus reducing molecular weight. Visa mer Synthesis The monomer is typically made from fermented plant starch such as from corn, cassava, sugarcane or sugar beet pulp. Several industrial … Visa mer PLA polymers range from amorphous glassy polymer to semi-crystalline and highly crystalline polymer with a glass transition 60–65 °C, a melting temperature 130-180 °C, and a Visa mer Consumer goods PLA is used in a large variety of consumer products such as disposable tableware, cutlery, housings for kitchen appliances and electronics such as laptops and handheld devices, and microwavable trays.
