Polylactic acid (PLA) bụ polymer polymerized na lactic acid dị ka ihe bụ isi akụrụngwa, nke enwetara n'ụzọ zuru ezu ma nwee ike ịmaliteghachi.Usoro mmepụta nke polylactic acid enweghị mmetọ, na ngwaahịa nwere ike imebi ya iji nweta mgbasa na okike, ya mere ọ bụ ezigbo ihe onwunwe polymer green.Polylactic acid ((PLA)) bụ ụdị ihe ọhụrụ nwere ike imebi ndụ makangwaahịa plastik, Mbipụta 3D.A na-eme starch nke ewepụtara site na akụrụngwa ihe ọkụkụ enwere ike imegharị (dịka ọka) ka ọ bụrụ lactic acid site na gbaa ụka wee ghọọ polylactic acid site na njikọ polymer.
