What is the raw material for PLA?

PLA is a type of polyester made from fermented plant starch from corn, cassava, maize, sugarcane or sugar beet pulp. The sugar in these renewable materials are fermented and turned into lactic acid, when is then made into polylactic acid, or PLA.

Is PLA made from oil?

Polylactic Acid, most commonly known as PLA, is a polymer made from renewable resources. Contrary to other thermoplastics which are petroleum-based, some of the raw materials used for PLA’s production include corn starch, tapioca roots, or sugar cane.

Does oil affect PLA?

Aliphatic hydrocarbons like a mineral oil should be fine — straight-chain hydrocarbon molecules don’t attack PLA. Aromatic hydrocarbons like benzene or toluene will attack PLA.

How is plant PLA derived?

How PLA is made. Corn plants are milled to extract the starch, in the form of glucose. The glucose is then fermented to produce lactic acid. Next up, a chemical process transforms the lactic acid into a polymer, which can be made into pellets, known in the industry as resin.

What is the raw material for 3D printers?

PLA plastic or Polylactic Acid is a vegetable-based plastic material, which commonly uses cornstarch as a raw material. It is the primary natural raw material used in 3D printing.

Is PLA a sustainable material?

Overall, it can be said that PLA is somewhat more sustainable than plastic from fossil fuels due to its production from renewable raw materials and the possibility of biodegradation. But it is and remains plastic that pollutes nature and the seas and it’s therefore important as with all plastic you use, to recycle it.

How much does it cost to produce PLA?

When it was first produced, PLA cost about $200 to make one pound. Thanks to innovations in manufacturing processes, it costs less than $1 per pound to manufacture today. Because it’s no longer cost-prohibitive, polylactic acid has the potential for massive adoption.
