kev kho dua tshiab rau lub sijhawm luv luv
3. Teeb meem nrog SLA tshuab
SLA qhov tseeb yog qhov zoo heev, tab sis muaj qee yam teeb meem nrog nws:
Qhov ceev ntawm kev luam ntawv tsis ceev heev.
Tsis zoo ntawm kev ua ntau yam ib zaug
Tus nqi ntawm cov khoom siv thiab kev tu vaj tse yog siab heev.
Vim li no, SLA yog qhov zoo dua rau cov ntawv thov kev kho hniav uas xav tau qhov tseeb heev thiab cov khoom me me.
Ⅳ DLP thev naus laus zis: ib qho ntawm cov thev naus laus zis nrov tshaj plaws siv hauv kev kho hniav
1. Lub tswv yim yooj yim tom qab DLP thev naus laus zis
DLP (Digital Light Processing) thev naus laus zis siv lub teeb pom kev digital (projector) los kho tag nrho cov txheej txheem ntawm ib zaug es tsis txhob luam nws ib qho ntawm ib zaug.
Nws muaj cov yam ntxwv no:
Txhua txheej yog qhib tib lub sijhawm.
Tsis tu ncua ceev ntawm cov khaubncaws sab nraud povtseg
Qhov no ua rau luam ntawv ntau npaum li cas.
2. Cov txiaj ntsig tseem ceeb ntawm DLP hauv kev kho hniav
Ntau tus neeg xav tias DLP thev naus laus zis yog ib qho zoo tshaj plaws 3D luam ntawv thev naus laus zis rau kev kho hniav tam sim no vim yog cov laj thawj hauv qab no:
Kev luam ntawv ceev ceev, zoo rau kev luam ntau
Txheej thickness yog txawm, thiab precision yog zoo ib yam.
Zoo rau luam tawm ntau cov qauv orthodontic thiab cov ntawv qhia ib zaug
DLP yog tam sim no xyaum ua ib qho kev teeb tsa tsis tu ncua hauv cov tuam txhab uas ua rau pom cov qauv orthodontic thiab cov qauv kho hniav.
3. Qhov twg tuaj yeem siv DLP
DLP tshuab yog zoo heev rau:
Invisible orthodontic qauv
Cov qauv kho hniav loj
Phau ntawv phaj rau cog
tom ntoo
DLP yog tus nqi ntau heev - kev xaiv zoo rau cov tuam txhab kho hniav kho hniav uas xav kom ua tau zoo thiab muaj cov khoom tawm tsis tu ncua.
Ⅴ LCD thev naus laus zis: qhov kev xaiv zoo tshaj plaws rau kev pib kho hniav
1. Lub tshuab LCD ua haujlwm li cas
Thaum koj siv LCD photopolymerization, lub vijtsam kua siv lead ua kua ua lub teeb pom kev zoo los kho tag nrho cov txheej ntawm cov resin ib zaug.
