Nyob rau hauv tus txheej txheem ntawm 3D luam ntawv, vim muaj ntau yam yuav ua rau cov drip molding shrinkage deformation, complex qauv ntawm cov qauv xav tau ntxiv cov txheej txheem kev txhawb nqa qauv, tus ntaiv nyhuv ntawm drip molding yuav tsum tau ua cov txheej txheem ntsuas los txo thiab lwm yam, ua ntej tsim cov qauv tsim yuav tsum tau teeb tsa qee cov txheej txheem. ntsuas kev hloov kho, kho lossis them nyiaj rau cov qauv digital.Muaj ob txoj hauv kev tseem ceeb rau kev ua haujlwm, ib qho yog ua haujlwm ncaj qha rau CAD 3D qauv, lwm qhov yog hloov kho, lossis kho cov ntaub ntawv scan, raws li tau piav qhia hauv qab no.
1. Ua haujlwm ncaj qha CAD 3D qauv
(1) Kho cov kev taw qhia ntawm cov qauv thaum lub sij hawm tsim khoom.
(2) Nthuav lossis txo cov qauv.
(3) Ua ntau yam qauv tib lub sijhawm.
(4) Teem txoj hauj lwm ntawm cov qauv ntawm lub lifting workbench.
2. Hloov lossis kho cov ntaub ntawv scanning
Txhawm rau txhim kho txoj kev tsim kom raug, cov ntaub ntawv peb-dimensional qauv tuaj yeem hloov kho thiab hloov kho, lossis cov ntaub ntawv scanning ntawm cov duab peb sab tuaj yeem hloov kho.
(1) Precision qhov chaw:nws hais txog qhov kev teeb tsa ntawm qhov siab tshaj plaws tso cai yuam kev ntawm ntu profile ntawm tus qauv tsim peb-dimensional thiab qhov tseeb scanning profile ntawm lub laser beam ntawm XY dav hlau.Qhov me dua qhov yuam kev, qhov smoother ntawm cov khoom.
(2) Ntu thickness teeb tsa ntawm cov qauv seem:Thaum seem thickness yog tas li, qhov me dua lub kaum sab xis ntawm qhov chaw thiab kab rov tav dav hlau, qhov ntau dua cov kauj ruam.Yog li ntawd, ib qho me me thickness tuaj yeem teem tau raws li kev coj ua ntawm tus qauv thiab lub kaum sab xis me me ntawm qhov chaw thiab lub dav hlau kab rov tav.
(3) Scanning trajectory offset:lub laser beam scanning contour yog loj dua tus tsim contour, yog li ntawd lub drip molding muaj ib tug ua tiav paj;Los yog ua kom lub scanning profile me dua qhov tsim profile, kom cov drip molding muaj cov npoo npoo.
(4) Ntxiv cov cushion hauv qab:nruab nrab ntawm tus qauv tsim thiab lub lifting platform yuav tsum tau teem ib txheej ntawm lub hauv qab cushion txhawb nqa ncej, thiaj li hais tias tus qauv ntawm lub lifting platform ib tug me ntsis kev ncua deb txoj kev, thiaj li hais tias cov txheej txheem tsis cuam tshuam los ntawm lub lifting platform unevenness.Underbed braces yog cov qauv uas zoo ib yam li nyias nyias daim hlau kom lawv tau yooj yim tshem tawm thiab tshem tawm ntawm qhov chaw qauv tom qab nws tau tsim.
(5) Ntxiv thav duab thiab kab ntawv txhawb nqa:Thaum UV irradiation ntawm lub photocuring resin los kho nws tag nrho, vim qhov shrinkage ntawm curing resin, yog li ntawd cov khoom yuav deformed nyob rau hauv txoj kev tsim, txawm li cas los xij yog siv los kho me ntsis ntawm qhov raug ntawm cov resin, tuaj yeem ua tau. tiv thaiv lub deformation ntawm workpieces.
(6) Xaiv txoj kev scan:muaj peb txoj kev rau laser beam luam theej duab ib seem, uas yog, scanning raws ntug ntawm lub sab profile ntawm seem;Kev soj ntsuam ntawm sab hauv honeycomb lattice qauv tshwj tsis yog contour npoo;Intensive sau scanning.Ib tug qauv nrog ib tug complex qauv yuav xaiv tau, thiab cov txheej txheem ntau lawm muaj xws li peb scanning hom hais saum toj no.Nws tuaj yeem siv cov qauv ua ke nrog rau kev teeb tsa ntawm kev hloov pauv, lub cev muaj zog thiab lwm yam kom ua tiav nws cov khoom tsim tawm, txhawm rau kuaj cov qauv.
Cov saum toj no yog los qhia yuav ua li cas lubSLA Lub teeb curing 3D tshuab luam ntawv molding txheej txheem yog los soj ntsuam,JS Additive tuaj yeem muab cov kev pabcuam SLA paub tab.Cia siab tias yuav muab cov ntaub ntawv rau koj.
