3D Luam Ntawv Tshuab Sib Pauv
FDM vs. SLA
FDM thiab SLA yog ob hom kev luam ntawv 3D hom. FDM cov tshuab luam ntawv MlT yas filamam kom ua cov khoom txheej los ntawm txheej. SLA cov tshuab luam ntawv siv cov kua dej ua kua uas hardens nrog lub teeb. Txhua hom muaj cov ntsiab lus zoo thiab tsis zoo rau cov luam ntawv tsis muaj kev txhawb nqa.
FDM luam tawm tuaj yeem luam tawm overhangs txog li ntawm 45℃-50℃nrog tsis muaj kev txhawb nqa. Yog lub kaum sab xis yog steeper, cov ntsiab lus yuav droop lossis sag. Txuas ntxiv mus ntev dua li 12 hli feem ntau tsis ua haujlwm vim lub ntiajteb txawj nqus tau rub tawm cov lus. Cov kev txhawb nqa yog xav tau rau lo lus qhia, uas siv ntau cov khoom siv thiab siv sijhawm ntau dua los ua tiav. Cov nplaim tuaj yeem saib cov ntxhib qhov twg txhawb kov cov luam tawm.
SLA luam tawm siv Resin kom du thiab cov khoom kom ntxaws. Lawv tuav cov khoom ntab zoo dua FDM. SLA txhawb nqa yog nyias thiab ua los ntawm tib lub resin raws li cov luam tawm. Cov kev txhawb nqa no yooj yim tshem tawm thiab tawm hauv cov cim tsawg dua. SLA luam tawm yog heev meej heev thiab muaj du ua tiav, txawm tias rau cov duab nyuaj. Lub resin hardens nrog lub teeb, yog li cov ntsiab lus me me yog ua tau, tab sis kev txhawb nqa tseem xav tau rau overhangs. SLA txhawb siv cov khoom siv tsawg dua thiab ua kom ntxuav tu tau yooj yim dua.

- Ob FDM thiab SLA cov tshuab luam ntawv yuav tsum muaj kev txhawb nqa rau overhangs thiab floating txheej. Txoj kev no txhawb txoj haujlwm no txawv rau txhua lub tshuab luam ntawv.
- FDM txhawb nqa yog loj thiab yuav tsum yog ib feem ntawm kev tsim. Lawv ua haujlwm zoo tshaj plaws rau kev tshaj lij tshaj 45 degree. Coj lawv lub sijhawm siv sijhawm thiab tuaj yeem tawm ntawm qhov chaw ntxhib.
- SLA txhawb nqa yog nyias thiab ua los ntawm cob. Tsob ntoo thiab laj kab duab pab txo kev sib cuag thiab ua kom yooj yim dua. Cov lus qhia me me tawm hauv cov cim ntev rau ntawm cov ntawv luam.
- SLA luam tawm tig qhov chaw rau kab nrog cov nta nrog z - axis. Cov lowers no tev. Lawv zam rau cov chaw dav dav thiab siv cov choj me me lossis cov kab ntawv sab hauv.
- Slicer software nrhiav pob uas xav tau kev txhawb nqa thiab ntxiv rau lawv. Cov neeg kuaj xyuas los ntawm txhais tes kom paub tseeb tias cov chaw tseem ceeb tau txais kev txhawb nqa txaus.
- SLA txhawb nqa yuav tsum ua tib zoo tshem tawm thiab xov, zoo li sanding lossis polishing, kom cov ntsiab lus ntse. FDM txhawb nqa muaj zog dua tab sis feem ntau tawm ntawm cov ntxhib.
- Txhawm rau tswj cov kev txhawb nqa tsis muaj kev txhawb nqa hauv SLA, khaws cia rau hauv qab 1mm lossis qaij lawv tsawg kawg 19℃los ntawm tiaj. Cov choj ntau dua 21mm tuaj yeem ua rau kev nqus thiab ua rog, yog li koj tso kev txhawb nqa teeb meem.
