Yog tias koj tsis npaj ua kom pleev xim rau saum npoo, koj tuaj yeem xuab zeb polycarbonate rau cov pob zeb zoo nkauj zoo nkauj ntau, tab sis nws raug nquahu kom siv cov pob zeb ua npuas ncauj ntau los thaiv cov kab ntoo. Kev txhuam los ntawm kev sib tsoo hauv kev sib tw me me tuaj yeem ua kom muaj ntau qhov kub thiab ua qee qhov ncav cuag t / g ntawm cov khoom. Yog li, kev siv dej yuav pab ua kom qhov kub thiab txias. Koj xav tau high-grain sandpaper (txog 600) thiab xuab zeb nws nrog cov dej me me (li 1/2 khob rau ib nti).
Kev sib tsoo yog thawj theem tseem ceeb hauv kev tsim cov ntawv luam 3D, thiab cov neeg siv khoom cia siab tias cov khoom yas yuav muaj qhov chaw du thiab ci. Yuav ua li cas du PLA phau ntawv qhia feem ntau yog ua tiav los ntawm kev sib tsoo lub 3D luam tawm, tab sis nws tawm huv.
Thaum sib tsoo PLA lossis lwm cov khoom siv qis-qis, nws yog ib qho tseem ceeb uas tsis tau raug ntxias kom siv lub tshuab hluav taws xob tsav. Koj tuaj yeem txuag lub dag zog ntawm kev luam ntawv nrog cov ntsiab lus siab los ntawm sanding PLA nrog lub khau tsis muaj zog xws li daim ntawv ntoo lossis cov xuab zeb zoo.
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 yog tias koj pom saum toj no, koj muaj 3D polishing zaj duab xis. Thaum sib tsoo koj cov ntawv luam 3D, peb pom zoo cov ntawv loj hauv qab no rau ultra-nplua 3D luam ntawv: lis loj 1 hli, 2 hli thiab 3 hli.
Kev ntub dej sib tsoo muaj cov txiaj ntsig loj kom ua tiav du thiab ci rau ntawm koj 3D-cov khoom luam tawm. AngstromLap 3D polishing cov ntawv ci tshwj xeeb yog tsim tshwj xeeb rau polishing 3D cov ntawv luam tawm thiab tuaj yeem siv tau ntub lossis qhuav. Lawv muaj qhov ruaj khov, txheej txheem yas thim rov qab uas ua rau lawv qhov tshwj xeeb tshaj rau cov xuab zeb ntub.
Yog tias koj muaj cov nplej loj ntawm cov ntawv me, koj kuj tuaj yeem siv cov qauv xuab zeb ntub rau koj cov khoom 3D-luam tawm. Siv sijhawm ntau rau koj sanding koj PLA prints, smoother koj yuav yog, tshwj xeeb tshaj yog nyob ib ncig ntawm cov npoo ntawm koj cov khoom.
Don' t txhawj xeeb yog tias koj yuav tsum siv sijhawm tsawg thiab tsawg sijhawm txav los ntawm ib qhov loj me rau lwm qhov, vim tias koj yuav tau ua tsawg dua txhua zaus.
Lub suab ntawd zoo li ntau yam haujlwm, tab sis tsis txhob' t txhawj xeeb, txhua qhov haujlwm tsuas yog siv ob peb feeb, yog li koj luam ntawv twb muaj qhov zoo tiav. Nws yog qhov zoo tshaj plaws yog tias koj siv cov ntawv ntub lossis qhuav los txhawm rau koj cov 3D luam ntawv (as txwv rau cov nyhuv beige), zoo li yog nws grinds sai, lub tshav kub tuaj yeem tsim thiab cuam tshuam rau thaj chaw du uas koj tau ua tiav. Thaum koj zom daim paib PLA, daim iav ntub dej tawm ntawm daim iav ua kom qhov saum npoo txias, ntub nws thiab tseem ua rau nws qis.
Qhov no tsis yog tib txoj kev los rhuav tshem qhov kub thiab txias ntawm 3D cov ntaub ntawv luam ntawv, tab sis nws yog ib qho tseem ceeb tshaj plaws hauv kev tsim cov khoom tiav 3D luam tawm.
Ntau qhov nyuaj dua yog qhov txuj ci xav tau los ntxuav 3D-luam qauv, thiab ntau txoj hauv kev tau siv los ua kom du 3D luam tawm. Kev sib tsoo yog qhov tsim nyog, tab sis kuj tuaj yeem ua tau los ntawm kev pleev xim rau saum npoo ntawm qhov yuam kev, piv txwv li rau ib qho khoom siv nrog thaj tsam loj.
Nrog cov txheej txheem du no, tus neeg teb xov tooj tuav lub nozzle hauv nws txhais tes uas tau tua ib qho hlaws me me ntawm nruab nrab dhau ntawm3D luam ib feemkom tshem tau cov kab ua ke. Hauv kwv yees li 5 - 10 feeb, lub hlaws blasting ua rau kom tiav qhov chaw tiav, thiab qhov txuas tau muab tso rau hauv chav hauv ob peb feeb.
Tus txheej txheem no muab PLA luam cov nplaim du uas zoo li lub ntsej muag du, tab sis yog tsim kom tiav nrog cov ncauj lus kom txaus kom nws zoo heev rau koj.
Muaj ntau cov txheej txheem kom tshem tawm lossis txo qhov feem cuam (txheej kab) hauv 3D luam ntawv, xws li siv lub tshuab txiav laser, lub tshuab txiav laser lossis txawm siv rab riam ntse.
Feem ntau nrog PLA filament, cov hau kev koj tuaj yeem siv yuav tsum rho tawm cov khoom sib txawv kom txog thaum nws du raws li koj xav tau. Thaum Polymaker siv PolySmooth PolyCast filament nrog nws cov khoom Polysher, nws cog lus tias yuav tshem tawm cov kab thiab muab qhov ua tiav zoo. Koj tuaj yeem siv ntau txoj hauv kev uas tuaj yeem siv rau PLA ntawm ABS, xws li lub tshuab txiav laser, rab riam ntse lossis txawm siv rab riam thiab xuab zeb.
Yog tias koj cuam tshuam nrog 3D luam ntawv, tej zaum koj paub zoo txog acetone thiab paub yuav ua li cas kom du tawm ntawm ABS luam tawm.
Txawm hais tias koj xav sau ABS, nws yog qhov nyuaj rau thov acetone rau qhov chaw hauv txoj kev tswj hwm. Acetone pib liquefy qhov chaw ntawm lub siab, txo qhov tseem ceeb ntawm txheej txheej. Nws cuam tshuam nrog ntu ABS thiab pib yaj cov yas tswj tau thiab maj mam, tab sis nws tsis ua rau muaj kev puas tsuaj rau cov ntu.
Kev ua kom tiav ntu ABS kuj tseem yuav yooj yim dua lub ntsej muag kom yooj yim, tab sis yog tias muaj dab tsi, qhov saum npoo hloov pauv ntawm matte mus rau matte. Tus txheej txheem no ua haujlwm zoo tshaj plaws thaum cov xim tha xim thiab cov txheej pib tshwm.
