PLA - Polylactic Acid

PLA (Polylactic Acid)

PLA (Polylactic Acid) is one of the two most commonly used desktop 3D printing materials. PLA is a corn based polymer and hence 100% environment friendly. PLA has property of low-warp and does not require a heated bed.On the whole PLA works better in the machine, requiring lower temperatures and giving stronger, more hard-wearing products.

It is a biodegradable thermoplastic derived from several renewable sources like sugarcane, cornstarch, and potato starch or tapioca roots. This way, PLA is the most eco-friendly plastic in 3D printing industry, when compared to other petrochemical based consumables like PVA or ABS.

PLA is used in surgical implants and medical suturing, as it can degrade in lactic acid present in the body. The surgically implanted pins, screws, mesh or rods just break down in your body from 6 months to 2 years.

This consumable is also used in bags, food packaging, upholstery, disposable tableware, hygiene products, disposable garments, and diapers. Hence, it is known to be a safe choice. For those looking to print PLA cups or other items for drink and food, keep in mind that the coloring pigments may not be as safe as PLA.
