Abubuwan Gyaran Halittu Mai Rarraba Injection Molding

Hannun masana'antu da yawa suna iya amfani da su (watau babban nauyin kwayoyin) PLA. Ana amfani da manyan monomers guda biyu: lactic acid, da cyclic di-ester, lactide. Hanyar da ta fi dacewa zuwa PLA ita ce polymerization na buɗewar zobe na lactide tare da nau'ikan ƙarfe daban-daban (yawanci tin octoate) a cikin bayani ko azaman dakatarwa. Ƙarfe-catalyzed dauki yana nufin haifar da tseren tsere na PLA, yana rage stereoregularity idan aka kwatanta da kayan farawa (yawanci sitaci masara).

PLA yana narkewa a cikin kewayon abubuwan kaushi na halitta. Ethyl acetate, saboda sauƙin samun dama da ƙananan haɗarin amfani, shine mafi yawan sha'awa. Filayen firinta na PLA 3D yana narkewa lokacin da aka jiƙa a cikin ethyl acetate, yana mai da shi kaushi mai amfani don tsaftace shugabannin bugu na 3D ko cire tallafin PLA. Wurin tafasa na ethyl acetate yana da ƙasa sosai don kuma santsi PLA a cikin ɗakin tururi, kama da yin amfani da tururi acetone don santsi ABS.

Sauran amintattun kaushi da za a yi amfani da su sun haɗa da carbonate propylene, wanda ya fi aminci fiye da ethyl acetate amma yana da wahalar siya ta kasuwanci. Hakanan ana iya amfani da Pyridine duk da haka wannan ba shi da lafiya fiye da ethyl acetate da propylene carbonate. Har ila yau yana da warin kifin da ya bambanta.
