Dab tsi yog Hom Lub Npe ntawm 3D Printing Technology?
Muaj ntau ntau hom kev tsim khoom siv thev naus laus zis. Feem ntau suav nrog FDM, SLA, DLP, SLS thiab hlau additive manufacturing.
1. FDM: Fused Deposition Modeling
Lub tshuab luam ntawv heats yas filament kom txog thaum nws ua molten thiab ces extrudes nws los ntawm lub nozzle. Cov ntaub ntawv yog muab tso rau hauv ib txoj kev predefined los tsim cov khoom txheej los ntawm txheej.
Cov ntaub ntawv FDM feem ntau suav nrog:
- PLA
- ABS
- PETG
- TPU
- Nylon
- PC
Qhov zoo ntawm FDM
- Tus nqi khoom siv tsawg tsawg
- Ntau yam khoom siv
- Yooj yim rau kev khiav lag luam
- Haum rau kev ceev prototyping
- Haum rau kev kawm thiab kev siv tus kheej
- Kev ua haujlwm zoo txhua yam nrog qee yam khoom siv engineering
Kev txwv ntawm FDM
- Pom cov kab kab
- Txwv tsis pub zoo - nthuav dav kev ua tau zoo piv nrog qee cov thev naus laus zis thev naus laus zis
- Qee cov ntaub ntawv muaj feem xyuam rau warping
- Kev luam ntawv ceev tuaj yeem txwv rau qhov nyuaj
FDM yog dav siv rau kev ua haujlwm prototypes, mechanical parts, fixtures, model and educational projects.
2. SLA: Stereolithography
SLA siv cov kua photosensitive resin ua cov khoom luam ntawv.
Lub laser xaiv exposes cov resin, ua rau nws mus rau ib tug photopolymerization cov tshuaj tiv thaiv thiab solidify.
Tom qab ib txheej yog kho, tsim platform txav thiab cov txheej tom ntej yog tsim.
Qhov zoo ntawm SLA
- High printing raug
- Smooth nto tiav
- Kev nthuav dav zoo heev
- Haum rau me me thiab complex Cheebtsam
Cov kev txwv ntawm SLA
- Resin tuaj yeem kim dua li FDM filament
- Feem ntau yuav tsum tau ntxuav thiab tom qab- kho
- Qee cov resins muaj kev txwv kev siv tshuab lossis ib puag ncig tsis kam
- Cov kua resin yuav tsum tau ua tib zoo tuav
SLA yog dav siv rau cov hniav nyiaj hniav kub, kev siv kho hniav, kev tsim qauv thiab cov qauv precision.
3. DLP: Lub teeb ua haujlwm digital
DLP yog lwm hom resin -raws li 3D tshuab luam ntawv.
Qhov sib txawv loj ntawm SLA thiab DLP yog txoj kev raug.
SLA feem ntau siv lub laser los luam theej duab qhov chaw xav tau, thaum DLP siv lub projector digital los nthuav tawm tag nrho cov txheej txheem ib zaug.
Qhov no tuaj yeem muab kev luam ntawv siab zoo nyob rau hauv cov xwm txheej tsim nyog.
Cov ntawv thov DLP ib txwm muaj xws li:
- Cov qauv kho hniav
- Cov hniav nyiaj hniav kub
- Precision Cheebtsam
- Muaj cov qauv tsim
DLP yog qhov tseem ceeb tshwj xeeb tshaj yog thaum muaj kev nthuav dav siab thiab ua tau zoo ntawm cov khoom me me.
4. SLS: Xaiv Laser Sintering
SLS siv cov khoom siv hmoov ua cov tshuab luam ntawv.
Lub laser xaiv heats thiab sinters tshwj xeeb thaj chaw ntawm cov hmoov raws li tus qauv digital. Tom qab ib txheej tiav lawm, lwm txheej ntawm hmoov yog siv.
Ib qho txiaj ntsig tseem ceeb ntawm SLS yog tias cov hmoov tsis sib haum nyob ib puag ncig tuaj yeem txhawb nqa cov khoom luam tawm, txo qhov xav tau ntawm cov qauv kev txhawb nqa ib txwm muaj.
Cov ntaub ntawv uas muaj xws li:
- PAB 12
- PAB 11
- TPU
- Lwm yam engineering- qib hmoov
Qhov zoo ntawm SLS
- Haum rau complex geometry
- Yam tsawg kawg nkaus kev txhawb nqa
- Zoo mechanical zog
- Haum rau qhov chaw ua haujlwm
- Tsim nyog rau tsawg- ntim ntau lawm
SLS yog dav siv nyob rau hauv tsheb, aerospace, neeg hlau, khoom siv thiab kev ua haujlwm prototyping.
5. Hlau 3D Printing
Hlau additive manufacturing muaj xws li technologies xws li SLM, DMLS thiab EBM.
Hauv laser hmoov txaj fusion, piv txwv li, ib txheej nyias ntawm cov hmoov hlau yog tso rau ntawm lub platform tsim. Lub siab -lub zog laser xaiv melts thaj tsam xav tau.
Tom qab ib txheej ua tiav, lwm txheej ntawm cov hmoov yog tso tawm thiab cov txheej txheem rov ua dua.
Cov khoom siv hlau muaj xws li:
- Stainless hlau
- Aluminium alloys
- Titanium alloys
- Nickel{0}}raws li alloys
- Cobalt- chrome alloys
Hlau 3D luam ntawv tuaj yeem tsim cov txheej txheem sab hauv uas yuav nyuaj lossis tsis yooj yim rau kev tsim khoom siv cov pa machining.
Yog li ntawd nws yog dav siv nyob rau hauv aerospace, kev kho mob, automotive, tooling thiab advanced industrial manufacturing.
