Polylactic Acid (PLA) yog tsim los ntawm kev ua ntau yam khoom cog, nws tau suav hais tias yog cov yas ntsuab piv rau ABS.Txij li thaum PLA yog muab los ntawm cov suab thaj, nws muab tawm ib nrab qab zib tsw thaum rhuab thaum luam ntawv.Qhov no feem ntau nyiam dua ABS filament, uas muab cov ntxhiab tsw ntawm cov yas kub.
PLA muaj zog dua thiab nruj dua, uas feem ntau tsim cov ntsiab lus ntse dua thiab cov fab piv rau ABS.Cov khoom 3D luam tawm yuav hnov zoo dua.Cov ntawv luam tawm kuj tuaj yeem ua sanded thiab machined.PLA muaj ntau dua warping piv rau ABS, thiab yog li lub rhuab tsim platform tsis tas yuav tsum tau.Vim tias tsis tas yuav tsum muaj lub txaj txaj txaj, ntau tus neeg siv feem ntau nyiam luam ntawv siv daim kab xev xiav es tsis txhob Kapton daim kab xev.PLA tseem tuaj yeem luam tawm ntawm qhov nrawm dua.
