3D luam ntawv yog ib daim ntawv ntawm additive manufacturing technology, nyob rau hauv uas cov khoom peb-dimensional yog tsim los ntawm ib tug nruam lub cev txheej. Piv nrog rau lwm yam kev tsim khoom siv thev naus laus zis, 3D tshuab luam ntawv muaj qhov zoo ntawm kev ceev ceev, tus nqi qis, thiab kev siv yooj yim. Lub tshuab luam ntawv 3D yog lub cuab yeej uas tuaj yeem "luam" cov khoom 3D tiag. Kev ua haujlwm yog tib yam li cov tshuab laser sib sau. Nws txais cov txheej txheem txheej txheem thiab cov txheej txheem superimposed, uas txhais tau hais tias 3D cov khoom tsim los ntawm kev ntxiv cov ntaub ntawv txheej los ntawm txheej, uas yog tib yam li cov khoom siv tshem tawm. Lub tshuab yog txawv kiag li. Nws yog hu ua "lub tshuab luam ntawv" nyob rau hauv kev siv rau nws cov txheej txheem kev, vim hais tias cov txheej txheem ntawm txheej txheej yog heev zoo li inkjet luam ntawv.

Lub tshuab luam ntawv 3D yog lub cuab yeej uas tuaj yeem "luam" cov khoom 3D tiag. Kev ua haujlwm yog tib yam li cov tshuab laser sib sau. Nws txais cov txheej txheem txheej txheem thiab cov txheej txheem superimposed, uas txhais tau hais tias 3D cov khoom tsim los ntawm kev ntxiv cov ntaub ntawv txheej los ntawm txheej, uas yog tib yam li cov khoom siv tshem tawm.

Nyob rau hauv xyoo tas los no, tus nqi ntawm 3D tshuab luam ntawv tau ua rau nws pheej yig rau cov lag luam me thiab nruab nrab, kom cov qauv tsim cov txheej txheem ntawm kev lag luam hnyav tuaj yeem ua tiav hauv chaw ua haujlwm ib puag ncig, thiab ntau hom khoom siv raw tuaj yeem muab tso rau hauv kev luam ntawv. .
Vim hais tias kev siv thev naus laus zis nrawm nrawm nyob hauv txoj haujlwm tseem ceeb hauv kev ua lag luam, 3D tshuab luam ntawv muaj peev xwm loj hauv kev siv ntau lawm. 3D tshuab luam ntawv tuaj yeem siv dav hauv cov hniav nyiaj hniav kub, khau, tsim kev lag luam, architecture, tsheb, aerospace, kho hniav thiab kho mob.
Cov txheej txheem luam ntawv ntawm txhua txheej yog muab faib ua ob kauj ruam. Ua ntej, ib txheej ntawm cov kua nplaum tshwj xeeb yog txau rau ntawm qhov chaw yuav tsim. Cov kua nplaum nplaum me me thiab tsis yooj yim rau kis. Tom qab ntawd tsuag ib txheej ntawm hmoov. Thaum cov hmoov ntsib cov kua nplaum, nws yuav sai sai thiab ruaj khov, thaum thaj chaw tsis muaj kua nplaum tseem xoob. Nyob rau hauv txoj kev no, nyob rau hauv lwm txheej ntawm cov kua nplaum thiab txheej ntawm hmoov, cov qauv khoom yuav raug "luam tawm" thiab tsim. Tom qab luam ntawv, tus qauv tuaj yeem "tshaj tawm" los ntawm cheb cov hmoov xoob, thiab cov hmoov seem tuaj yeem rov ua dua.
Printing consumables yog hloov los ntawm ib txwm number case thiab ntawv rau kua nplaum thiab hmoov. Yog lawm, cov kua nplaum thiab hmoov yog ua tiav cov ntaub ntawv tshwj xeeb, uas tsis tsuas yog yuav tsum tau kho cov tshuaj tiv thaiv ceev, tab sis kuj muaj kev cuam tshuam ncaj qha rau lub zog ntawm tus qauv thiab kev daws teeb meem ntawm "luam". Lub tshuab luam ntawv 3D tam sim no tuaj yeem ua tiav 600dpi daws teeb meem, thiab txhua txheej muaj qhov tuab ntawm 0.01 hli xwb. Txawm hais tias muaj cov ntawv lossis cov duab nyob rau saum npoo ntawm tus qauv, nws tuaj yeem luam tawm kom meej. Tau kawg, txwv los ntawm lub hauv paus ntsiab lus ntawm inkjet luam ntawv, lub tshuab luam ntawv nrawm yog khi kom tsis txhob nrawm heev. Tam sim no, cov khoom lag luam siab tshaj tuaj yeem ua tiav qhov nrawm nrawm ntawm 25 hli ib teev, uas yog 10 npaug siab dua li ntawm cov khoom dhau los, thiab tuaj yeem siv cov xim pleev xim kom ua tiav xim luam ntawv. Cov xim qhov tob yog txog 24 ntsis.
Vim muaj qhov raug luam ntawv siab, qhov zoo ntawm cov qauv luam tawm yog ib txwm zoo. Ntxiv nrog rau kev qhia txog tus qauv tsim ntawm lub contour nkhaus, cov qauv thiab txav mus los kuj tsis muaj teeb meem. Yog tias nws yog siv los luam cov khoom sib dhos, lub zog, bearings, khi pas nrig, thiab lwm yam tuaj yeem txav tau ib txwm, thiab txoj haujlwm ntawm cov yam ntxwv ntawm cov kab noj hniav xws li kab noj hniav thiab grooves yog qhov tseeb, thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua. Cov khoom luam tawm tuaj yeem ua polished, drilled, thiab electroplated. Thiab lwm txoj hauv kev rau kev ua haujlwm ntxiv. Tib lub sijhawm, cov ntaub ntawv hmoov tsis txwv rau cov ntaub ntawv xuab zeb, thiab lwm yam ntaub ntawv xws li elastic expansion, high-performance composite, peev casting, thiab lwm yam.
