Polylactic Acid, feem ntau hu ua PLA, yog ib qho ntawm cov khoom siv nrov tshaj plaws siv hauv desktop 3D luam ntawv. Nws yog lub neej ntawd filament ntawm kev xaiv rau feem ntau extrusion-based 3D tshuab luam ntawv vim nws tuaj yeem luam tawm ntawm qhov kub thiab tsis xav tau lub txaj rhuab.
PLA sawv cev rau dab tsi hauv 3D luam ntawv?
PLA yog cov khoom siv 3D nrov tshaj plaws.
PLA stands rau polylactic acid (los yog polylactide). Cov khoom siv thermoplastic no yooj yim luam tawm, biodegradable, thiab pheej yig. Nws feem ntau yog siv rau kev tsim qauv sai, ua cov qauv ua yeeb yam, lossis lub hom phiaj kev kawm.
Vim li cas PLA zoo rau 3D luam ntawv?
PLA yog cov neeg siv khoom siv thermoplastic nrog siab zog thiab tawv dua ob ABS thiab nylon. Nrog rau qhov kub thiab txias qis thiab qis qis, PLA yog ib qho ntawm cov ntaub ntawv yooj yim tshaj plaws rau 3D luam ntawv tiav. … Tsis tas li ntawd, PLA yog nkig, ua rau cov khoom tsis zoo thiab muaj kev cuam tshuam.
PLA yas puas muaj zog?
PLA yog ib puag ncig tus phooj ywg, compostable filament uas luam tau yooj yim ntawm qhov kub thiab txias thiab zoo li zoo. Nws tseem zoo nkauj heev. … Qhia tseeb, peb xav tsis thoob nrog PLA lub zog. Txawm li cas los xij, nrog lub zog tensile ntawm 7, 250 psi, qhov no yog cov khoom siv muaj zog.
Dab tsi yog qhov tsis zoo ntawm kev luam ntawv nrog PLA?
- Cov ntsiab lus melting tsawg ua rau PLA tsis haum rau cov ntawv thov kub. PLA tseem tuaj yeem pom cov tsos mob ntawm qhov muag muag lossis deforming ntawm lub caij ntuj sov hnub kub.
- PLA muaj qhov permeability ntau dua li lwm cov yas. Cov dej noo thiab oxygen yuav nkag mus tau yooj yim dua li lwm cov yas. …
- PLA tsis yog cov yas nyuaj tshaj plaws lossis tawv tshaj plaws.
