3D luam ntawv, tseem hu ua additive manufacturing, yog cov txheej txheem ntawm kev tsim cov khoom peb-dimensional los ntawm cov qauv digital.Tsis zoo li cov txheej txheem kev tsim tawm ib txwm muaj, uas cuam tshuam nrog kev txiav tawm ntawm cov khoom thaiv, 3D luam ntawv tsim cov khoom kawg los ntawm kev ntxiv cov khoom siv los ntawm txheej.Qhov txheej txheem ntawm txheej txheej no tuaj yeem tsim cov duab ntau thiab cov qauv uas yuav nyuaj lossis tsis yooj yim sua kom ua tiav siv cov txheej txheem ib txwm muaj.3D luam ntawv tuaj yeem siv ntau yam ntaub ntawv, suav nrog plastics, hlau, ceramics, thiab txawm tias cov khoom siv roj ntsha xws li cov hlwb muaj sia.Nyob rau tib lub sijhawm 3D luam ntawv muaj qhov zoo xws li prototyping sai, customization, txo cov khoom pov tseg, thiab muaj peev xwm los tsim cov qauv tsim nrog siab precision.Nws yog dav siv nyob rau hauv ntau industries xws li aerospace, automotive, kev kho mob, kev tsim kho thiab cov neeg siv khoom rau prototyping, tooling thiab end-siv ib feem ntau lawm.Niaj hnub no tsab xov xwm no yuav qhia 3D luam ntawv los ntawm lawv hom thiab cov yam ntxwv.
Thawj ib-Fused Deposition Modeling
1. FWM
Txoj haujlwm ua haujlwm:
Fused deposition modeling yog ib qho ntawm cov paub zoo tshaj plaws ntawm 3D luam ntawv.Nws ua haujlwm los ntawm kev thawb cov hlua yas los ntawm lub tshuab cua sov.Cov yas molten yog ces nteg ib txheej los ntawm txheej kom txog rau thaum ib feem tiav.Muaj ntau ntau hom 3D filament muaj - los ntawm cov khoom siv thermoplastics rau cov thermoplastic elastomers hloov tau.
Nta:
Qhov tsis zoo:
1. Kev luam ntawv nrawm nrawm
2. Cov khoom luam tawm muaj cov txheej tuab tuab
Thib ob - Lub Teeb - Kho
1. SLA
Txoj haujlwm ua haujlwm:
Stereolithography yog thawj lub lag luam muaj 3D tshuab luam ntawv.Nws ua haujlwm los ntawm kev sib zog ua kua photopolymer rau hauv qhov kawg los ntawm kev taug qab lub zog siab laser mus rau ib lub phaj tsim nyob rau hauv cov duab ntawm qhov chaw hla ntu.Cov txheej txheem txuas ntxiv raws li txhua txheej tom ntej sib sau ua ke mus rau txheej dhau los.Cov tshuab no tsim cov khoom nrog cov yam ntxwv zoo heev.
Nta:
Qhov tsis zoo:
1. Cov khoom yog khaus thiab me ntsis lom
2. Nqis
3. Tom qab luam ntawv, ntxuav, tshem tawm lub bracket, thiab UV irradiation rau theem ob curing.
2. LCD
Txoj haujlwm ua haujlwm:
3D LCD tshuab luam ntawv yog lub tshuab luam ntawv uas siv lub teeb-kho resin luam ntawv thev naus laus zis.Tsis zoo li cov tshuab luam ntawv 3D ib txwm luam tawm txheej txheej, LCD 3D tshuab luam ntawv siv UV teeb los luam tag nrho cov khaubncaws sab nraud povtseg ib zaug.Qhov no txhais tau hais tias 3D luam ntawv nrog lub tshuab luam ntawv 3D LCD sai dua thiab meej dua nrog lwm lub tshuab luam ntawv 3D.
Dab tsi teeb tsa LCD 3D tshuab luam ntawv sib nrug ntawm lwm hom 3D tshuab luam ntawv, xws li DLP lossis SLA tshuab luam ntawv, yog lawv lub teeb ci.LCD 3D tshuab luam ntawv siv UV LCD arrays ua lub teeb ci.Yog li ntawd, lub teeb los ntawm LCD vaj huam sib luag hits thaj chaw ua hauj lwm ncaj qha nyob rau hauv ib tug parallel yam.Vim tias lub teeb no tsis nthuav dav, pixel distortion yog qhov teeb meem tsawg dua rau LCD luam ntawv.
Nta:
Qhov tsis zoo:
1. Lub vijtsam LCD muaj lub neej luv luv thiab yuav tsum tau hloov tom qab luam ntawv ntau txhiab teev.
2. Cov khoom yog khaus thiab me ntsis lom.
Thib peb-Powder Fusion
SLS, SLM
Txoj haujlwm ua haujlwm:
Selective laser sintering ua hauj lwm los ntawm muab ib txheej ntawm hmoov yas thiab tracing tus ntoo khaub lig-section ntawm ib feem nrog ib tug laser.Lub laser melts cov hmoov thiab fuses nws.Lwm txheej ntawm cov hmoov yas yog muab tso rau saum cov txheej dhau los, thiab lub laser melts cov duab ntoo khaub lig thaum fusing rau hauv txheej dhau los.Yog tias muaj cov kev tawm mus rau cov hmoov tsis muaj hmoov nplej, cov txheej txheem tuaj yeem tsim cov khoom muaj tseeb uas tuaj yeem luam tawm hauv qhov chaw.
Nta:
Qhov tsis zoo:
1. Tus nqi yog kim heev
2. Warping yog nquag tshwm sim thaum luam ntawv loj qhov chaw
3. Muaj ntxhiab tsw loj thaum ua haujlwm
Cov ntsiab lus
Kab lus no qhia txog qhov sib txawv 3D tshuab luam ntawv thiab feature raws li hom 3D luam ntawv.Txhawm rau kawm paub ntau ntxiv txog hom 3D luam ntawv thiab ntau ntxiv txog kev txhim kho koj cov khoom luam 3D,tiv tauj peb.
