PLA (Poly-lactic Acid or polylactide) has easy print-ability which makes it widely used in 3D printing.
PLA is a thermoplastic aliphatic polyester derived from renewable biomass, typically from fermented plant starch such as from corn, cassava, sugarcane. PLA had the second highest consumption volume of any bio-plastic of the world.
PLA is used as medical implants in the form of anchors, screws, plates, pins, rods, and as a mesh. PLA can also be used as a decomposable packaging material, either cast, injection-molded, or spun. Cups and bags have been made from this material.
In the form of a film, it shrinks upon heating, allowing it to be used in shrink tunnels.
It is useful for producing loose-fill packaging, compost bags, food packaging, and disposable tableware.
In the form of fibers and non-woven fabrics, PLA also has many potential uses, for example as upholstery, disposable garments, awnings, feminine hygiene products, and diapers.
In 3D printing, PLA (Poly-lactic Acid) filament is the most common and broadly used material. PLA has a strength of about 70 ~ 80% or more compared to ABS filament and can be deformed at high temperatures.
The melting point of PLA is around 180°C and unlike ABS, it does not shrink easily even when the temperature decreases, so it is possible to print variety of designs relatively stable and easy.
