Thaum feem ntau ntawm kev tsim khoom ua tiav hauv lub tshuab luam ntawv 3D raws li cov khoom tsim los ntawm txheej, qhov ntawd tsis yog qhov kawg ntawm cov txheej txheem. Tom qab ua tiav yog ib kauj ruam tseem ceeb hauv 3D luam ntawv ua haujlwm uas hloov cov khoom luam tawm rau hauv cov khoom tiav. Ntawd yog, "post-processing" nws tus kheej tsis yog cov txheej txheem tshwj xeeb, tab sis yog ib pawg uas muaj ntau yam kev ua haujlwm sib txawv thiab cov txheej txheem uas tuaj yeem siv tau thiab ua ke kom tau raws li qhov xav tau ntawm kev zoo nkauj thiab kev ua haujlwm sib txawv.

Raws li peb yuav pom ntau yam ntxiv hauv tsab xov xwm no, muaj ntau cov txheej txheem tom qab ua tiav thiab ua tiav cov txheej txheem, suav nrog cov txheej txheem tom qab ua tiav (xws li kev txhawb nqa tshem tawm), nto smoothing (lub cev thiab tshuaj), thiab xim ua. Nkag siab txog cov txheej txheem sib txawv uas koj tuaj yeem siv hauv 3D luam ntawv yuav tso cai rau koj kom ua tau raws li cov khoom lag luam tshwj xeeb thiab cov kev xav tau, txawm tias koj lub hom phiaj yog kom ua tiav qhov zoo ib yam, kev zoo nkauj tshwj xeeb, lossis nce kev tsim khoom. Cia wb mus saib ntxiv.

Cov txheej txheem tom qab ua tiav feem ntau yog hais txog thawj kauj ruam tom qab tshem tawm thiab ntxuav cov 3D luam tawm los ntawm lub plhaub sib dhos, suav nrog kev txhawb nqa tshem tawm thiab cov txheej txheem yooj yim smoothing (hauv kev npaj rau cov txheej txheem smoothing ntau dua).

Ntau cov txheej txheem luam ntawv 3D, suav nrog fused deposition modeling (FDM), stereolithography (SLA), direct hlau laser sintering (DMLS), thiab carbon digital light synthesis (DLS), yuav tsum tau siv cov qauv kev txhawb nqa los tsim kev sib tw, txuas hniav, thiab cov qauv tsis yooj yim. . . peculiarity. Txawm hais tias cov qauv no muaj txiaj ntsig zoo hauv cov txheej txheem luam ntawv, lawv yuav tsum tau muab tshem tawm ua ntej cov txheej txheem tiav tuaj yeem siv tau.

Kev tshem tawm cov kev txhawb nqa tuaj yeem ua tau ntau txoj hauv kev, tab sis cov txheej txheem niaj hnub no feem ntau cuam tshuam nrog kev tuav tes, xws li txiav, tshem tawm cov kev txhawb nqa. Thaum siv cov dej-soluble substrates, cov qauv kev txhawb nqa tuaj yeem raug tshem tawm los ntawm kev muab cov khoom luam tawm hauv dej. Kuj tseem muaj cov kev daws teeb meem tshwj xeeb rau kev tshem tawm ib feem, tshwj xeeb tshaj yog cov khoom siv hlau ntxiv, uas siv cov cuab yeej xws li CNC tshuab thiab cov neeg hlau kom raug txiav cov kev txhawb nqa thiab tswj kev ua siab ntev.

Lwm txoj hauv kev tom qab ua tiav yog sandblasting. Cov txheej txheem cuam tshuam nrog txau cov ntawv luam tawm nrog cov khoom nyob rau hauv siab. Qhov cuam tshuam ntawm cov khoom siv tshuaj tsuag rau ntawm qhov chaw luam tawm tsim ib qho smoother, ntau yam kev ntxhib los mos.

Sandblasting feem ntau yog thawj kauj ruam hauv kev ua kom lub ntsej muag 3D luam tawm zoo vim nws tshem tawm cov khoom seem thiab tsim kom muaj qhov sib xws ntau dua uas yog npaj rau cov kauj ruam tom ntej xws li polishing, pleev xim lossis pleev xim. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias sandblasting tsis ua kom ci los yog glossy tiav.

Tshaj li qhov yooj yim sandblasting, muaj lwm cov txheej txheem tom qab ua tiav uas tuaj yeem siv los txhim kho qhov smoothness thiab lwm yam khoom nto ntawm cov khoom luam tawm, xws li matte lossis glossy tsos. Qee zaum, cov txheej txheem ua tiav tuaj yeem siv los ua kom tiav smoothness thaum siv cov khoom siv sib txawv thiab cov txheej txheem luam ntawv. Txawm li cas los xij, nyob rau hauv lwm qhov xwm txheej, nto smoothing tsuas yog haum rau qee hom kev tshaj tawm lossis luam tawm. Ib feem geometry thiab cov ntaub ntawv luam tawm yog ob qho tseem ceeb tshaj plaws thaum xaiv ib qho ntawm cov hauv qab no smoothing txoj kev (tag nrho muaj nyob rau hauv Xometry Instant Pricing).

Txoj kev ua haujlwm tom qab no zoo ib yam li cov ntawv xov xwm sandblasting nyob rau hauv uas nws koom nrog kev siv cov khoom rau cov ntawv luam tawm hauv siab. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb: sandblasting tsis siv cov khoom siv (xws li xuab zeb), tab sis siv cov iav hlaws kheej kheej ua qhov nruab nrab rau sandblast cov ntawv luam tawm ntawm kev kub ceev.

Qhov cuam tshuam ntawm cov iav hlaws nyob rau saum npoo ntawm cov ntawv luam tawm ua rau cov nyhuv smoother thiab ntau dua. Ntxiv nrog rau cov txiaj ntsig zoo nkauj ntawm cov xuab zeb blasting, cov txheej txheem smoothing ua rau cov neeg kho tshuab lub zog ntawm qhov tsis cuam tshuam nws qhov loj me. Qhov no yog vim hais tias cov duab kheej kheej ntawm cov iav hlaws tuaj yeem muaj qhov cuam tshuam loj heev rau ntawm qhov chaw.

Tumbling, tseem hu ua kev tshuaj ntsuam xyuas, yog ib qho kev daws teeb meem zoo rau kev ua cov khoom me me tom qab. Cov thev naus laus zis suav nrog muab 3D luam tawm rau hauv lub nruas nrog rau cov khoom me me ntawm ceramic, yas lossis hlau. Lub nruas ces tig los yog vibrates, ua rau cov khib nyiab rub tawm ntawm cov ntawv luam tawm, tshem tawm qhov tsis sib xws ntawm qhov chaw thiab tsim kom muaj qhov chaw du.

Media tumbling muaj zog ntau dua li sandblasting, thiab qhov smoothness tuaj yeem hloov kho nyob ntawm seb cov khoom siv tumbling. Piv txwv li, koj tuaj yeem siv cov ntawv xov xwm uas tsis tshua muaj txiaj ntsig los tsim kom muaj qhov ntxhib ntxhib ntxhib ntxhib ntxhib ntxhib ntxhib los mos, thaum siv cov chips siab grit tuaj yeem ua rau lub ntsej muag smoother. Qee qhov kev ua tiav loj tshaj plaws tuaj yeem ua qhov ntsuas 400 x 120 x 120 mm lossis 200 x 200 x 200 mm. Qee zaum, tshwj xeeb tshaj yog nrog MJF lossis SLS qhov chaw, lub rooj sib txoos tuaj yeem ua polished nrog cov cab kuj.

Thaum tag nrho cov txheej txheem smoothing saum toj no yog ua raws li cov txheej txheem ntawm lub cev, chav smoothing cia siab rau cov tshuaj tiv thaiv ntawm cov ntaub ntawv luam tawm thiab chav ua kom lub ntsej muag du. Tshwj xeeb tshaj yog, kev ua kom muaj zog ua rau muaj kev nthuav tawm 3D luam tawm rau cov kuab tshuaj evaporating (xws li FA 326) hauv chav ua haujlwm kaw. Cov chav ua raws li qhov chaw ntawm cov ntawv luam tawm thiab tsim cov tshuaj tiv thaiv yaj, smoothing tawm txhua qhov chaw tsis zoo, ridges thiab hav los ntawm redistributing cov khoom molten.

Chav smoothing kuj paub tias muab qhov chaw polished thiab glossy tiav. Feem ntau, cov txheej txheem ua kom zoo nkauj yog kim dua li lub cev smoothing, tab sis nyiam dua vim nws cov smoothness zoo dua thiab glossy tiav. Vapor Smoothing yog sib xws nrog feem ntau cov polymers thiab elastomeric 3D luam ntawv cov ntaub ntawv.

Xim raws li cov kauj ruam tom qab ua tiav yog ib txoj hauv kev zoo los txhim kho qhov zoo nkauj ntawm koj cov ntawv luam tawm. Txawm hais tias 3D luam ntawv cov ntaub ntawv (tshwj xeeb tshaj yog FDM filaments) tuaj nyob rau hauv ntau yam xim xaiv, toning raws li cov txheej txheem tom qab tso cai rau koj siv cov ntaub ntawv thiab cov txheej txheem luam ntawv uas ua tau raws li cov khoom specifications thiab ua tiav cov xim kom haum rau cov khoom muab. khoom. Ntawm no yog ob txoj kev xim ntau tshaj plaws rau 3D luam ntawv.

Kev pleev xim pleev xim yog ib txoj hauv kev nrov uas siv cov tshuaj aerosol los siv txheej xim rau 3D luam ntawv. Los ntawm kev ncua 3D luam ntawv, koj tuaj yeem pleev xim sib npaug ntawm ib feem, npog nws tag nrho saum npoo. (Tej xim kuj tuaj yeem siv tau xaiv los ntawm kev siv cov txheej txheem npog ntsej muag.) Txoj kev no yog ib txwm siv rau ob qho tib si 3D luam tawm thiab cov khoom siv tshuab thiab yog tus pheej yig. Txawm li cas los xij, nws muaj ib qho teeb meem loj: txij li tus number case yog siv thinly, yog tias cov ntawv luam tawm yog khawb los yog hnav, cov xim qub ntawm cov khoom luam tawm yuav pom. Cov txheej txheem shading hauv qab no daws qhov teeb meem no.

Tsis zoo li cov tshuaj tsuag pleev xim lossis txhuam hniav, tus number case hauv 3D luam ntawv nkag mus rau hauv qab ntawm qhov chaw. Qhov no muaj ob peb qhov zoo. Ua ntej, yog tias 3D luam tawm tau hnav lossis khawb, nws cov xim vibrant yuav nyob twj ywm. Cov stain kuj tsis tev tawm, uas yog cov xim uas paub ua. Lwm qhov txiaj ntsig zoo ntawm dyeing yog tias nws tsis cuam tshuam rau qhov tseeb ntawm qhov luam tawm: txij li cov xim nkag mus rau saum npoo ntawm tus qauv, nws tsis ntxiv thickness thiab yog li tsis ua rau poob ntawm cov ntsiab lus. Cov txheej txheem xim tshwj xeeb yog nyob ntawm 3D luam ntawv txheej txheem thiab cov ntaub ntawv.

Tag nrho cov txheej txheem tiav no tuaj yeem ua tau thaum ua haujlwm nrog tus khub tsim khoom xws li Xometry, tso cai rau koj los tsim kev tshaj lij 3D luam ntawv uas ua tau raws li kev ua tau zoo thiab cov qauv zoo nkauj.
