Cov txheej txheem tsim khoom ntxiv yog tsim los nrog ntau cov kauj ruam, thiab tsuas yog thaum txhua kauj ruam tau ua kom zoo tuaj yeem tau txais qhov kawg precision qhov chaw, suav nrog theem qauv, theem luam ntawv, thiab lwm yam. Thaum ua haujlwm ntawm 3D tshuab luam ntawv tiav, feem ntau nws tus kheej. yuav tsum tau machined: qhov no yog post-processing. Tom qab ua tiav yog hais txog tag nrho cov haujlwm ua haujlwm tom qab tshem tawm ntawm lub tshuab, suav nrog tab sis tsis txwv rau kev ntxuav, npaj nto, annealing, thiab txawm tias xim. Cov txheej txheem tom qab ua tiav hauv 3D luam ntawv muaj ntau yam raws li cov txheej txheem tsim khoom nws tus kheej, thiab txhua tus muaj nws tus kheej cov cai tshwj xeeb. Tab sis vim li cas cov kauj ruam no tseem ceeb heev rau 3D luam ntawv? Lub lag luam qauv ntawm 3D luam ntawv tom qab ua tiav yog dab tsi?
Tom qab ua tiav hauv 3D luam ntawv feem ntau yog siv los txhim kho qhov zoo nkauj ntawm cov khoom tsim thiab lawv cov kev ua tau zoo. Piv txwv li, ua rau qhov chaw smoother los yog annealing Cheebtsam kom lawv lub zog thiab hloov lawv cov hluav taws xob conductivity. Txawm hais tias qee cov txheej txheem tom qab ua tiav kuj tseem muaj nyob rau hauv 3D txheej txheem luam ntawv, feem ntau cov txheej txheem tom qab ua tiav raws li lwm txoj kev tsim khoom ntau dua li kev tsim khoom ntxiv. Cov txheej txheem tom qab ua tiav hauv cov txheej txheem tsim khoom ntxiv yog qhov sib txawv me ntsis, piv txwv li, FDM qhov chaw yuav tsum tau ua tiav txawv dua li cov hlau. Yog li ntawd, tom qab ua tiav yog ib qho tseem ceeb uas yuav tau xav txog thaum lub sij hawm 3D luam ntawv txheej txheem.

Taw qhia txog cov txheej txheem tom qab ua tiav
● Thawj yog kev ntxuav ntawm qhov chaw. Kev ntxuav ntawm qhov chaw muaj ntau yam, xws li desoldering, flushing, txhuam, tshuab, thiab lwm yam. Lub hom phiaj yog tshem tawm cov hmoov nplej ntau dhau los yog cov khoom siv resinous. Nyob ntawm cov txheej txheem luam ntawv siv, cov kauj ruam no yuav siv sij hawm sib txawv. Rau cov hmoov sintering, piv txwv li, qhov no feem ntau yog cov kauj ruam siv sijhawm uas ua rau lub sijhawm tsim khoom.
● Hom thib ob yog annealing. Cov kauj ruam no tsuas yog ua kom qhov kub thiab txias ntawm ib feem los txhim kho nws cov khoom siv kho tshuab. Cov khoom siv kho tshuab no suav nrog kev ua haujlwm kub, tiv thaiv UV, thiab txawm tias lub zog lossis thermal stability. Cov kauj ruam no feem ntau suav nrog cov khoom siv polymer - piv txwv li, rau cov txheej txheem resin, muaj cov tshuab "kho" tsim ncaj qha rau cov tshuab luam ntawv tshwj xeeb. Rau hmoov-bonded los yog indirect hlau 3D luam ntawv txheej txheem, nws yuav tsum tau degreased thiab ces sintered nyob rau hauv ib tug haum qhov cub. Yog li ntawd, cov txheej txheem annealing feem ntau yog siv los txhim kho cov khoom kawg thiab kev ua haujlwm ntawm qhov chaw.
● Muaj ob chav kawm ntawm kev ua haujlwm uas tuaj yeem siv los txhim kho qhov zoo ntawm ib feem: Kev Kho Ntog thiab Ntxig.
Cov qub suav nrog txhua txoj kev siv los txhim kho cov tsos: smoothing, polishing, sandblasting, nkag los yog milling. Muaj ntau cov txheej txheem tam sim no muaj los hloov kho qhov chaw ntawm ib feem los ntawm kev ntxiv lossis tshem tawm cov khoom. Piv txwv li, xuab zeb tshem tawm qhov tsis sib xws ntawm qhov chaw, thaum txau ntxiv ib txheej ntawm cov khoom kom ci zoo dua.
Coloring mas yog hais txog dyeing thiab painting. Qhov kev xaiv ntawm ob feem ntau yog nyob ntawm cov khoom siv luam ntawv. Piv txwv li, dyeing yog tsim nyog rau cov txheej txheem polymer hmoov, thaum tshuaj tsuag pleev xim zoo dua rau cov khoom siv FDM.
Postprocessing cov txiaj ntsig thiab kev txwv
● Tom qab ua tiav hauv 3D luam ntawv yog ib kauj ruam tseem ceeb hauv kev txhim kho qhov pom ntawm ib feem, nrog rau kev txhim kho nws cov khoom kawg. Ua tsaug rau cov thev naus laus zis sib txawv, 3D-luam cov khoom tuaj yeem ncav cuag lawv lub peev xwm thiab tuaj yeem muag tau ua qhov kawg siv.
● Kev ua tiav tom qab tso cai rau cov neeg siv los kho qee qhov kev luam tawm tsis xws luag, uas tuaj yeem "camouflaged" los ntawm kev tshem tawm cov tsos ntawm cov txheej luam tawm. Tsis tas li ntawd, vim tias tom qab ua tiav, qee qhov khoom yas muaj cov khoom zoo sib xws rau cov khoom siv hlau, uas txo tus nqi zoo heev.

Tau kawg, kev ua haujlwm tom qab kuj tseem muaj cov kev sib tw thiab cov kev txwv uas lub khw tau sim daws rau ntau xyoo. Ib qho ntawm cov teeb meem loj tshaj plaws hauv kev ua tiav 3D luam ntawv yog lub sijhawm xav tau. Raws li kev tshawb fawb txhua xyoo luam tawm los ntawm PostProcess Technologies, 53 feem pua ntawm cov neeg koom tau hais tias lawv qhov kev sib tw loj tshaj plaws yog lub sijhawm ua haujlwm tom qab. Cov kauj ruam no tseem siv sij hawm dhau mus thiab swb lub hom phiaj ntawm kev txo lub sijhawm tsim khoom nrog 3D luam ntawv. Yog li ntawd, cov txheej txheem automated tau dhau los ua kev xaiv ntawm ntau tus kws tshaj lij hauv kev ua haujlwm. Cov kauj ruam automated no txo cov neeg ua haujlwm thiab ua kom cov neeg ua haujlwm nyab xeeb. Yog li, JR ntseeg tias automation yog ib qho ntawm cov qauv tseem ceeb hauv kev ua lag luam, ob qho tib si hauv kev ua haujlwm tom qab thiab hauv kev luam ntawv tiag tiag ntawm cov khoom, thiab peb tos ntsoov yuav pom kev hloov tshiab ntxiv hauv cheeb tsam no!
