Polylactic acid (PLA) ipolymer yakagadziriswa nelactic acid sezvinhu zvikuru, iyo inowanikwa zvizere uye inogona kudzorerwa patsva. Maitiro ekugadzira polylactic acid haana kusvibiswa, uye chigadzirwa chinogona kuora kuti chifambe zvakanaka, saka chinhu chakakodzera che green polymer. Polylactic acid ((PLA)) imhando itsva yezvinhu zvinoora zvezvigadzirwa zvepurasitiki, Kudhinda kwe3DSitachi inotorwa kubva muzvirimwa zvinodzorerwa (senge chibage) inogadzirwa kuita lactic acid nekuvirisa uye yozoshandurwa kuita polylactic acid kuburikidza nekugadzirwa kwepolymer.

Poly (lactic acid) ine mukana wakanaka wekuora kwehupenyu uye inogona kuora zvachose ne100% yetupukanana turi muvhu mukati megore rimwe chete mushure mekusiyiwa, zvichikonzera carbon dioxide nemvura uye kusasvibiswa kwezvakatipoteredza. Zvinoita sekuti "kubva kune zvakasikwa, ndezvezvisikwa". Kuburitswa kwecarbon dioxide pasi rose maererano nemishumo yenhau, tembiricha yepasi rose ichakwira kusvika 60 ℃ muna 2030. Mapurasitiki akajairwa achiri kupiswa, zvichikonzera huwandu hwakawanda hwemagasi egreenhouse kuti aburitswe mumhepo, nepo polylactic acid ichivigwa muvhu kuti iparare. Kabhoni dioxide inobuda inopinda zvakananga muzvinhu zvakasikwa zvevhu kana kuti inotorwa nemiti, haizoburitswi mumhepo, haizokonzere Greenhouse Effect.

Poly (lactic acid) yakakodzera nzira dzakasiyana dzekugadzirisa dzakadai sekuumba mabhuroko uyejekiseni kuumbwa. Zviri nyore kugadzirisa uye zvinoshandiswa zvakanyanya. Inogona kushandiswa kugadzirisa marudzi ese emidziyo yechikafu, chikafu chakaputirwa, mabhokisi ekudya kwemasikati ekukurumidza, machira asina kurukwa, machira emuindasitiri neemumba kubva kumakambani kusvika kumakambani. Uye yozogadziriswa kuita machira ekurima, machira ehutano, machira ekuchenesa, machira ekunze anodzivirira ultraviolet, machira etende, matiresi epasi nezvimwewo, musika unoratidza tariro huru. Zvinogona kuonekwa kuti hunhu hwayo hwemakanika nehwemuviri hwakanaka.

Hunhu hwepolylactic acid (PLA) uye petrochemical synthetic plastics hwakafanana, kureva kuti, inogona kushandiswa zvakanyanya kugadzira zvigadzirwa zvakasiyana-siyana zvekushandisa. Polylactic acid inewo kupenya kwakanaka uye kujeka, iyo yakafanana nefirimu yakagadzirwa nepolystyrene uye haigone kupihwa nezvimwe zvigadzirwa zvinoora.
