Yuav ua li cas du PLA phau ntawv qhia feem ntau yog ua tiav los ntawm kev sib tsoo3D luam tawm qhov chaw, tab sis nws yog ib qho tseem ceeb kom tsis txhob raug ntxias kom siv cov xuab zeb uas tau tsav. Thaum koj zom cov PLA lossis lwm cov khoom siv uas tsis tshua muaj kev kub ntxhov, koj tuaj yeem txuag lub dag zog ntawm kev luam ntawv nrog tus siab-filaments thiab tau txais kev huv.
Thaum cov khoom 3D muaj ntau dua lossis tsawg dua mus txog cov yam xav tau, qhov kawg tiav yuav tsum tau siv rau kev ua tiav. Yog tias koj xav tau cov nplaim du raws li saum toj no, peb pom zoo kom tsis txhob hla cov kauj ruam no, tab sis thaum sib tsoo 3D luam, peb pom zoo cov nplej hauv qab no.
Kev sib tsoo yuav tsum tau ua tas mus li qhov kev hloov mus ncig me me, thiab cov tes taw sib tsoo zoo dua li tes sib dhos lossis lub tshuab dhos.
Tom qab sanding nrog high grain sandpaper, koj tuaj yeem txau daim nyias, txawm tias txheej ntawm xeb roj tso rau hauv kev luam ntawv kom tiav nws nrog cov xim pib lossis tshuaj tsuag hauv kev sib xyaw nrog cov txheej txheem sanding. Qhov thib peb txoj hauv kev ua tiav PLA luam ntawv yog siv primer thiab tshuaj tsuag - ntawm kev pleev xim ua kev sib txuam ntawm cov xuab zeb thiab kev siv tshuab. Tom qab sanding, cov khoom 3D tuaj yeem tuaj yeem muab nrog qhov xav tau qhov chaw rau polishing, kua roj vanish, lossis varnishing.
Qhov no suab zoo li ntau yam haujlwm, tab sis tsis txhob txhawj' t txhawj xeeb, cov khoom poob tawm hauv ob peb feeb thiab ua tiav ntawm tus nqi me me ntawm nplaim luam ntawv. Txhua txheej tsuas siv ob peb feeb, yog li koj luam ntawv twb muaj qhov ua tiav zoo.
Thaum sib tsoo PLA luam tawm, daim iav ntub cov ntawv ua rau lub ntsej muag txias rau saum npoo, lubricates nws thiab txias nws cia me ntsis. Yog tias koj tab tom siv cov ntawv ntub lossis qhuav los xau koj 3D luam ntawv (as as beige), nws yog qhov zoo tshaj plaws rau kev coj ua zoo, vim tias yog koj xuab zeb nrawm, kub yuav tsim tau thiab cuam tshuam rau thaj chaw du koj xav kom ua tiav.
Qhov kawg thiab lom zem tshaj plaws yog thaum koj pib pib polishing koj PLA luam. Yog tias koj xav kom koj lub tshuab luam ntawv 3D ua tiav xws li daim iav, koj yuav tsum tsim kom tau txog 3000%, tab sis nws pom tau tias yeej yooj yim thiab polishes zoo nkauj thiab tusyees. Qhov no tsis yooj yim xws li nplawm qhov kub ntawm qhov 3D luam tawm cov khoom.
Qhov kawg tshwm sim zoo nkaus li zoo tom qab polishing, tab sis cov khaubncaws sab nraud povtseg ntawm nthwv txhuam tsis ua' t xav zoo li koj' tau ua tiav zoo.
Ua ntawv thov rau cov 3D luam tawm saum npoo thiab tsom mus rau qhov tau txais qhov tiaj tiaj los ntawm kev txav mus txog 600 grits. Daim duab xuab zeb yuav txhuam cov XTC thiab 3 D txheej, yog li txhuam qee qhov txhuam ntawm qhov chaw, tab sis tsis ntau nws yuav ua kev puas tsuaj.
Thaum koj ua tiav sanding, nco ntsoov tias koj ntxuav qhov huv kom huv nrog xab npum thiab dej thiab tom qab ntawd nws qhuav nrog cua compressed ua ntej yuav mus rau kauj ruam tom ntej. Lub PLA huv si yog coated nrog XTC thiab 3D, tab sis cov xim PLA seem yog cov xim nrog cov xim dub. Tsis tas li ntawd, cov hnab ris hauv puab yog cov xuab zeb tsis zoo thiab muaj qee qhov teeb meem nrog kev sib koom ua ke.
Txhawm rau kom cov ntawv txhuam av ntxuav, nws raug nquahu kom xuab zeb luam tawm txij thaum pib los ua kom tiav kom tiv thaiv kev txhuam thiab kev txhim kho kom sov - thiab tsis ua rau lub qhov puas. Tom qab sanding qhov gradation thiab tiv thaiv kom tsis txhob muaj plua plav thiab khoom qab zib, koj tuaj yeem ntxuav koj lub siab nrog xab npum thiab dej.
FDM qhov chaw tuaj yeem yog hauv av kom muaj pob kws muaj txog li 5000 kom ua tiav qhov chaw du, ci ntsa iab, tab sis tsis pub ntau tshaj 500 nplej rau ntau qhov chaw polished.
Feem ntau, nws yog qhov zoo dua rau cov xuab zeb ib feem los ntawm kev ua haujlwm maj mam dhau ntawm qhov chaw nrog cov noob pob zeb qis thiab maj mam nce qib ntawm cov ntawv sandpaper tsawg kawg plaub zaug ua ntej ua tiav nws nrog cov nplua lis. Nws yog qhov tsawg dua kev siv zog ua haujlwm kom muaj cov ntsiab lus siab nrog cov ntsiab lus sib txuas thiab kev txhawb nqa cov qauv tab sis yuav tsum sib tsoo kom tshem tawm cov khaubncaws sab nraud povtseg thiab kab kom paub meej sib luag.
Nco ntsoov tias siv lub teeb kov kom tsis txhob muaj cov ntsiab lus me me lossis ua kom muaj kev ncaj ncees rau qhov ntev ntawm lub ntu. Txhuam cov nplaim nrog cov nplua-nplua-nplua sandpaper thiab txhuam maj mam dhau ntawm sab saud nrog koj txhais tes lossis txhuam ib qho me me.
Thaum sanding luam tawm, Iftakher pom zoo kom siv cov hom ntaws zuj zus, xws li 1/4-nti ntawv, thiab sanding nws nrog cov ntawv loj dua ua ntej kom tshem tawm qhov tsis sib xws thiab khawb. Koj kuj tseem xav siv cov qib zoo zoo rau kev daws teeb meem ntau dua, tshwj xeeb tshaj yog ntawm thawj txheej. Koj tuaj yeem ntxuav koj cov ntawv pleev ua ke ob peb zaug, xyuas seb puas muaj qhov nqaij me me uas ploj lawm, thiab muab nws tso ua ntej koj pib dua.
Thaum lub siab tau sanded zoo lawm, nws tuaj yeem luam thiab polished lossis sanded nqes mus rau daim iav xav tau - zoo li ib qho tiav uas cuam tshuam rau kev zam. Ib qho aerosol primer tsim rau cov qauv pleev xim muab txawm tias muaj kev pov hwm thiab tuaj yeem ua kom paub meej tias cov ntsiab lus ntawm koj cov luam ntawv tsis tau them ua ntej pleev xim. Koj tsuas yog yuav tsum thov txog li 600 grits pleev xim, tab sis yog tias koj xav tau daim iav npaj, xuab zeb luam tawm me ntsis ntxiv, vim tias qhov no yuav cuam tshuam rau koj kam rau ua.
