Sla vs. FDM: Sib piv ntau 3D luam ntawv tshuab luam ntawv
Feb 10, 2025
Tso lus
3D luam ntawv tshuab tau tsim los rau hnub thiab tau dhau los ua kev lag luam tseem ceeb hauv kev tsim khoom lag luam, hloov cov khoom lag luam yog tsim thiab tsim khoom. Ntawm ntau cov tshuab luam ntawv 3D luam tawm, SLAOROography) thiab FDM (fused repigition modeling) yog ob qhov kev siv tshuab ntau thiab dav siv tshuab. SLA siv ultraviolet lasers rau irradiat feats thiab solorify lawv txheej los ntawm txheej los tsim peb-seem. Cov thev naus laus zis no tuaj yeem tsim cov khoom nplua thiab nyuaj nrog cov khoom siab heev thiab du thaj chaw, thiab tuaj yeem siv cov khoom xa tawm ntawm ntau yam xim thiab textures. FDM Heats thiab melts yas ua kom zoo, thiab tom qab ntawd tso nyiaj txheej txheej txheej txheej los ntawm cov extruder los ua ib qho khoom. Nws lub hauv paus ntsiab lus yog yooj yim, cov nqi peev thiab cov nqi siv tsis muaj tsawg, thiab kev luam ntawv ceev yog nrawm. Nws yog dav siv nyob rau hauv cov tsev neeg, kev kawm ntawv hauv tsev kawm ntawv, thiab ntau lawm me me, tab sis nws yog qis dua rau SLA qhov tseeb thiab zoo. Nkag siab txog cov yam ntxwv, qhov zoo thiab cov kev txwv ntawm SLA thiab FDM yog qhov tseem ceeb rau kev tsim nyog muaj yees siv tshuab ntawm kev lag luam sib txawv thiab cov xwm txheej. Kab lus no yuav ua ib qho kev txheeb xyuas ntawm SLA thiab FDM, ob qhov 3D luam ntawv thev naus laus zis, yog li ua kev txiav txim siab zoo hauv kev siv.

5.Tab kom siv SLA thiab FDM
1.What yog FDM lub tshuab luam ntawv 3D?
Fused Depeadition Modeling Modeling (FDM), Kuj tseem hu ua filent filleuric (fff), yog feem ntau 3D luam ntawv thev naus laus zis ntawm kev ua lag luam. Feem ntau, FDM cov tshuab luam tawm tau nruab nrog ib qho lossis dual extruders uas tau sib haum nrog thermoplastic filaments. Cov filaments yog thauj khoom mus rau hauv lub tshuab los ntawm cov khoom siv tsiaj, melted, thiab muab tso rau ntawm cov luam ntawv rhuab raws li lub cuab tam primectory. Cov ntaub ntawv txias synchronously thaum lub sijhawm tso nyiaj thiab ua raws li txhua tus los tsim ib qho kev sib tw peb sab.
FDM cov tshuab luam ntawv muaj ntau yam tshwj xeeb thiab cov khoom siv txawv txawv, thiab cov nqi ntau li ntau los ntawm Asmeskas $ 5, {}, {3}}. Cov ntaub ntawv siv tau xws li cov plastics xws li abs, thiab pla, thiab cov ntaub ntawv luam tawm pib dua 3D cov ntaub ntawv muaj zog, uas muaj zog dua thiab muaj lub neej kev pab ntau dua.
1.1Yog FDM 3D Printing ua haujlwm?
FDM, yog ib qho ntawm cov ntawv luam tawm ntxov ntawm 3D luam ntawv, tau tsim los ntawm Scott Crump, ib qho ntawm cov khoom siv ntawm Stratasys. Lub hauv paus ntsiab lus yog heev yooj yim heev, ib yam li siv phom kub kub. Ib hom ntawm thermoplastic fuabament los yog yas yog rhuab rau melting point. Cov kua kub kua yas yog extruded los ntawm lub nozzle thiab ua ib txheej nyias nyias ntawm cov ntawv luam ntawm X thiab Y Axes. Cov txheej no sai sai txias thiab ua kom tawv. Tom qab txhua txheej ua tiav, lub platform qis dua thiab ntau dua molten yas tau muab tso cia, ua ntu ntu loj tuaj raws cov z axis.
2.What yog SLA 3D tshuab luam ntawv?
Cov hnub qub (SLA nkag mus rau hauv kev ua lag luam xyoo 1980s thiab tau txais kev tshawb fawb sai los ntawm ntau cov kev pabcuam tuam txhab thiab cov neeg lag luam cov khoom lag luam. Hloov chaw ntawm cov filaments, sra 3D tshuab luam ntawv siv cov photopolymers, uas yog lub teeb pom cov khoom siv uas hloov pauv cov cev thaum hloov lub teeb. Hloov chaw ua haujlwm los ntawm kev extrusion nozzle, sla luam ntawv siv lasers kom muaj kua roj los ntawm cov txheej txheem hu ua photocuring.
Cov txheej txheem luam tawm tshwj xeeb no muaj peev xwm tsim cov chaw siab daws teeb meem uas yog isotropic thiab waterproof. Photopolymers yog cov khoom siv hluav taws xob, uas txhais tau tias lawv hnov sib txawv rau cov ntaub ntawv thermopicastic. Zoo ib yam li FDM, SLA luam tawm yog muaj nyob rau ntau qhov ntau thiab tsawg, cov khoom sib xyaw, thiab tus nqi li.
2.2How ua cov ntawv luam tawm li 3D?
SLA siv cov photopolymer resins raws li cov khoom siv raw rau ntu. Photopolymers xav tau kev mob siab ultraviolet teeb los ntawm laser teeb, uas yog lub tswv yim tseem ceeb ntawm SLA. Kev tsim tau tshwm sim rau ntawm lub platform raus hauv txhab. Lub laser saum lub tank, coj los ntawm precision tsom iav, kho cov kua rov qab txheej - los ntawm - txheej los ua cov duab uas xav tau. Ua ntej, cov qauv txhawb nqa tau tsim kom nrawm rau lub platform thiab muab kev txhawb nqa kom tsim nyog. Tom qab txhua daim ntawv hla, ib tug recoater hniav tsoo lub resin lub nrog sab saud saum toj no ib feem ntawm ib feem thiab khoom siv ntau cov khoom siv ntxiv. Ib feem yog tsim los ntawm hauv qab.

4.CHARCRACTORY NTAWM SLA thiab FDM tshuab luam ntawv 3D
4.1features ntawm sra 3D tshuab luam ntawv
Ultra-siab precision:
SLA cov tshuab luam ntawv siv ultraviolet laseriolet thev naus laus zis zoo heev, thiab tuaj yeem ua kom zoo me me uas tuaj yeem ncav cuag cov ntawv tuab ntawm cov ntawv luam ntawv. Thaum ua cov ntu nrog cov qauv ntau ntawm cov qauv microfluidic thiab cov khoom siv txhais tes ua kom txhua yam, nyob deb lwm yam ntxiv rau lwm yam thev naus laus zis.
Cov Khoom Siv Zoo:
Nws siv cov ntaub ntawv teeb ci thiab tau kho tau sai thiab tsim los ntawm ultraviolet hluav taws xob. Txawm li cas los xij, cov khoom siv no yog cov khoom siv thickosetting, thiab cov khoom ua tau ntau dua nkev tshaj thermoplastics. Raws li lub sijhawm raug rau ultraviolet rays nce, nws yuav tsis tsuas yog ua brittle, tab sis kuj tseem thim. Lub neej pabcuam tiag tiag feem ntau yog hais txog 8-12 lub hlis, thiab nws yog feem ntau haum rau kev siv luv luv lossis ib-zaug ntau lawm.
Zoo nkauj nto CONENTENE:
Cov txheej qhov siab ntawm SLA luam tawm pib ntawm tsuas {{{{}}}}}}}}}}}}}}}}}}}}. Qhov no ua rau kev sib txuas ntawm txheej thaum lub sijhawm cov txheej txheem luam ntawv tsis muaj nruj, thiab yuav luag tsis muaj cov kab piv. Qhov saum npoo ntawm cov khoom luam tawm yog du thiab tiaj, thiab cov kev xav tau zoo yuav ua tiav yam tsis muaj kev sib tw tom qab.
Kev thov tshwj xeeb:
SLA luam ntawv muaj qhov tseem ceeb nyob hauv thaj chaw prototyping, raws li lawv tuaj yeem hloov kho cov qauv ntawm lub cev, ua kom cov kev xav tau ntawm cov qauv ua kom zoo nkauj nrog cov kev pom zoo thiab cov ntsiab lus. Nyob rau tib lub sijhawm, SLA luam tawm yog qhov kev xaiv zoo tshaj plaws thaum ua cov feem me thiab txoj kev ua kom nruj ntawm qhov tseeb thiab qhov chaw zoo. Txawm li cas los xij, lawv tsis haum rau cov khoom luam uas yuav tsum tau siv rau lub sijhawm ntev thiab feem ntau raug rau kev ntxhov siab.
4.2features ntawm fdm tshuab luam ntawv
Cov ntaub ntawv nplua nuj thiab tus nqi qis:
FDM cov tshuab luam ntawv siv ntau yam ntawm thermoplastic cov ntaub ntawv, suav nrog absoplastic ntaub, nrog rau abs, petg, thiab tseem siv tau pp lossis cov khoom siv roj carbon. Cov khoom siv nqi yog tsawg, thiab muaj ntau xim xws li Abs thiab PLA xaiv los ntawm. Tsis tas yuav muaj kev pleev xim lossis zas dej lossis zas xim tom qab kev tsim khoom, thiab cov ntaub ntawv tsis muaj peev xwm pheej yig dua li cov nyiaj yuav tsum muaj rau SLA.
Tsawg tus nqi tsim qauv nqi:
FDM yuav tsum yuav luag tsis muaj cov txheej txheem ntxiv tshwj tsis yog lub tshuab nws tus kheej. Tsis zoo li cov chaw nres tsheb SLA, uas yuav tsum tau kho cov chaw so thiab UV tom qab raug kho kom haum rau cov kauj ruam cov qib siab no thiab txo cov nqi. FDM luam ntawv Software txhawb nqa cov chaw hauv lub sijhawm ua haujlwm thiab hloov cov khoom siv sib txawv nrog cov kev siv nyiaj tsawg, txo cov nqi ntxiv thiab txo tus nqi.
Qhov chaw ruaj khov:
Thaum siv cov ntaub ntawv xws li Abs lossis Nylon, FDM feem ntau ruaj dua li cov ua los ntawm SLA. SLA qhov chaw yog rhiab rau lub teeb vim yog txoj kev uas lawv tsim, thiab lawv zoo li ploj mus thaum raug teeb thaum muaj teeb, thaum FDM ntu tsis muaj qhov teeb meem no.
Muaj cov luam tawm:
FDM Luam Ntawv Kev Taw Qhia muaj qhov cuam tshuam zoo rau cov khoom siv neeg kho tshuab. Tsis muaj kev sib tshooj ntawm cov khaubncaws sab nraud povtseg ntawm txheej, thiab qhov chaw yog ib feem ntawm txoj kab txheej txheej. Thaum tsim qauv, nws yog qhov tsim nyog kom nkag siab txog kev quab yuam kom tsis txhob muaj lub zog tseem ceeb rub cov khaubncaws sab nraud povtseg; Kev ua kom zoo nkauj tsis zoo yog qhov zoo li lwm cov qauv kev luam ntawv 3D, txheej txheej yog qhov pom tseeb, thiab kev ua haujlwm tom qab feem ntau yuav tsum tau; Hlau txias yuav tsim cov kev txwv Geometric, 90-} Lub kaum sab xis ua rau tev, ua rau muaj kev ntxhib.
5.Tab kom siv SLA thiab FDM
Qhia ob lub tswv yim thiab muaj feem cuam tshuam los muab cov kev xaiv:
