3D Printing yog dab tsi?
3D printing yog ib qhoadditive manufacturing technologiesy uas tsim peb - cov khoom seem txheej txheej los ntawm cov qauv digital.
Tsis zoo li cov txheej txheem tsim tawm ib txwm muaj xws li CNC machining, milling thiab drilling, 3D luam ntawv tsis pib nrog cov khoom loj loj thiab tshem tawm cov khoom tsis tsim nyog. Hloov chaw, nws ntxiv cov khoom siv tsuas yog qhov uas nws xav tau raws li tus qauv tsim digital.
Hauv cov ntsiab lus yooj yim:
Traditional manufacturing:Khoom siv → Txiav / Machining → Khoom
3D luam ntawv: Cov qauv digital → Slicing → Layer -los ntawm - txheej luam ntawv → Khoom
Qhov no ua rau 3D luam ntawv tshwj xeeb muaj txiaj ntsig rauceev prototyping, complex geometry, customized khoom thiab tsawg- ntim manufacturing.
3D Printing ua haujlwm li cas?
Txawm hais tias sib txawv 3D luam ntawv thev naus laus zis siv cov ntaub ntawv sib txawv thiab cov txheej txheem tsim, cov txheej txheem ua haujlwm yooj yim zoo sib xws.
1. Tsim 3D Digital Model
Thawj kauj ruam yog los tsim ib qho peb - qauv siv CAD software xws li SolidWorks, Fusion 360 lossis lwm yam 3D qauv software.
3D qauv kuj tuaj yeem rub tawm los ntawm cov tsev qiv ntawv online thiab khaws cia hauv hom xws li:
- STL
- OBJ
- 3 xf
Cov qauv digital txhais cov duab thiab qhov ntev ntawm cov khoom kawg.
2. Txiav 3D qauv
Lub tshuab luam ntawv 3D tsis tuaj yeem ib txwm luam tawm 3D qauv ncaj qha.
Hloov chaw, slicing software hloov cov qauv mus rau hauv ib txheej ntawm ob- txheej txheej.
Piv txwv li, yog tias tus qauv yog 100 hli siab thiab txheej qhov siab yog 0.2 hli:
100 ÷ 0.2=500 txheej
Lub slicer tseem tsim cov lus qhia tseem ceeb luam ntawv, suav nrog:
- Txheej qhov siab
- Kev luam ntawv ceev
- Ua kom ceev
- Kev luam ntawv
- Txhawb cov qauv
- Nozzle kub
- Lub txaj kub
- Kev ntsuas cua txias
Cov lus qhia tshwm sim feem ntau hloov mus rau G-code lossis lwm lub tshuab- nyeem tau hom ntawv.
3. Tsim Cov Khoom Txheej Txheem los ntawm Txheej
Lub tshuab luam ntawv 3D ua raws cov lus qhia tsim los ntawm lub tshuab txiav thiab tsim cov khoom ib txheej ib zaug.
Txawv technologies siv ntau txoj kev:
- FDM:Melts thiab extrudes yas filament
- SLA:Siv lub laser los kho cov kua resin
- DLP:Siv cov teeb pom kev zoo los kho cov resin
- SLS:Siv lub laser rau sinter hmoov
- SLM/DMLS:Siv high -lub zog lasers los ua cov hmoov hlau
Txawm hais tias lawv qhov sib txawv, lawv txhua tus ua raws tib lub ntsiab lus tseem ceeb:
Hloov tus qauv 3D rau hauv 2D txheej thiab tsim cov khaubncaws sab nraud povtseg rau hauv 3D khoom.
4. Tshaj tawm -Kev ua haujlwm
Tom qab luam ntawv, qee cov khoom siv tau tam sim ntawd, thaum lwm tus xav tau kev ua haujlwm ntxiv.
Cov ntawv tshaj tawm - cov txheej txheem ua tiav suav nrog:
- Tshem tawm kev txhawb nqa
- Sanding
- Ntxuav
- UV kho
- Kev pleev xim
- Polishing
- Kev kho cua sov
- Nto xov
Yog li ntawd, qhov kawg zoo ntawm 3D- cov khoom luam tawm tsis yog nyob ntawm lub tshuab luam ntawv nkaus xwb, tab sis kuj tseem nyob ntawm cov khoom siv, luam ntawv tsis pub dhau thiab tshaj tawm - txheej txheem txheej txheem.
