Dab Tsi Yog Qhov 3D Luam Ntawv Thiab Nws Ua Haujlwm Li Cas?

Lub tshuab luam ntawv 3D yog ib hom tshuab ntawm cov tshuab ua qauv tiv thaiv sai. Nws yog hom ntawm cov qauv ntaub ntawv digital ua lub hauv paus, siv cov hmoov hlau los yog yas thiab lwm yam khoom siv sib cog los tsim cov khoom los ntawm luam ntawv txheej los ntawm txheej. Lub sijhawm, cov software ua tiav cov kev sib tshooj ntau los ntawm lub koos pij tawj-pab tsim (CAD) thiab xa cov ntaub ntawv hlais mus rau lub tshuab luam ntawv 3D, uas muab cov khaubncaws sab nraud povtseg ua tiav mus txog thaum cov khoom txua tau. Qhov loj tshaj qhov sib txawv ntawm 3D tshuab luam ntawv thiab tshuab luam ntawv ib txwm yog tias" number case" nws siv yog cov khoom siv tiag tiag.

Txoj haujlwm ua haujlwm ntawm lub tshuab luam ntawv 3D yog qhov tseem zoo ib yam li ntawm lub tshuab luam ntawv ib txwm muaj. Lawv muaj li ntawm kev tswj cov khoom siv, kev siv tshuab, luam tawm hau, siv khoom, thiab tshaj tawm. Cov tshuab luam ntawv no zoo ib yam.

Lub tshuab luam ntawv 3D tsuas yog tsim cov qauv ua tiav peb ntu ntawm lub computer ua ntej luam ntawv, thiab tom qab ntawd luam nws tawm. Muaj ntau ntau yam ntawm txheej txheej nyias nyias siv hauv 3D luam ntawv. Cov tshuab luam ntawv 3D siv siv Fused Deposition Modeling (FDM). Fuse tsub zuj zuj kuj tseem hu ua fuse txuam nrog. Nws yog txheej txheem ntawm cua sov thiab ablating filamentous kub-yaj cov ntaub ntawv thiab extruding lawv los ntawm lub suab nrov nrog lub nplua nozzle. Tom qab cov khoom siv kub yaj tag lawm, nws tau tawm ntawm lub nozzle thiab piled rau ntawm lub vaj huam sib luag lossis txheej dhau los ntawm cov khoom ua tiav. Tom qab qhov kub txias dua qhov kub ntawm lub solidification, nws pib ua kom muaj zog, thiab qhov khoom kawg yog tsim los ntawm kev tsub zuj zuj ntawm txheej txheej.

Ntawm cov 3D luam ntawv thev naus laus zis, FDM muaj cov qauv tshuab qauv yooj yim, kev tsim qauv yooj yim, thiab tus nqi qis tshaj plaws tsim khoom, tiv thaiv tus nqi, thiab cov nqi khoom siv. Yog li no, nws tseem yog cov khoom siv thev naus laus zis hauv tsev ntau tsim cov tshuab luam ntawv 3D. Cov txheej txheem kev ua haujlwm yog thawj zaug los ntawm lub khoos phis tawj cov qauv software, yog tias koj muaj cov qauv npaj, xws li cov qauv tsiaj, cov cim lossis cov qauv me, thiab lwm yam. Cov ntaub ntawv STL siv cov duab peb ceg ntsej muag kom kwv yees qhov pom ntawm yam khoom. Qhov me dua qhov peb tog, qhov siab dua qhov kev daws teeb meem ntawm qhov chaw sib tsoo. Tom qab ntawv luam mus rau 3D tshuab luam ntawv los ntawm SD daim npav, lossis txuas ncaj qha rau lub computer thiab 3D tshuab luam ntawv nrog USB cable, thiab tom qab teeb tsa tus luam ntawv, lub tshuab luam ntawv tuaj yeem luam tawm. Hauv cov txheej txheem luam ntawv, lub tshuab luam ntawv nyeem cov ntawv sau sib kis hauv cov ntawv, txo cov ntu ntu nrog cov khoom kub, thiab luam tawm cov ntawv hla txheej los ntawm txheej, thiab tom qab ntawd tsim ib qho chaw ua haujlwm.

Cov yam ntxwv ntawm lub thev naus laus zis yog tias nws tuaj yeem tsim cov khoom ntawm txhua hom duab. Lub tuab ntawm cov ntoo khaub lig-luam tawm los ntawm lub tshuab luam ntawv (uas yog, Z-axis kev taw qhia) thiab kev daws teeb meem hauv qhov kev taw qhia dav hlau, uas yog, X-axis-Y-axis kev taw qhia yog xam ua dpi (pixels ib nti) lossis micrometers. Cov tuab tuab dav yog 100 microns, lossis 0.1 hli, thiab qee qhov luam tawm tuaj yeem luam ntawv txheej li nyias li 16 microns. Qhov kev taw qhia dav hlau tuaj yeem luam tawm cov kev daws teeb meem nyob ze ntawm lub tshuab luam ntawv laser. Qhov taub ntawm luam tawm" number case poob" feem ntau 50 txog 100 microns. Feem ntau nws siv sijhawm li ob peb teev mus rau ob peb hnub los ua tus qauv uas siv cov qauv qub, nyob ntawm tus nplai thiab qhov tsis khov. Kev siv tshuab peb-txheej txheem luam ntawv tuaj yeem ua rau lub sijhawm luv luv mus rau ntau teev, yog lawm, nws tau txiav txim siab los ntawm txoj haujlwm ntawm lub tshuab luam ntawv thiab ntsuas qhov ntsuas thiab qhov ntau thiab tsawg ntawm qhov tsis khov ntawm tus qauv.

Cov txheej txheem kev lag luam ib txwm muaj xws li kev txhaj tshuaj moulding tuaj yeem tsim cov khoom lag luam polymer ntawm tus nqi qis, thaum peb lub tshuab luam ntawv loj tuaj yeem tsim cov khoom lag luam tsawg tsawg hauv kev ua kom nrawm dua, yoog raws, thiab qis tus nqi. Lub tshuab luam ntawv 3D-ua haujlwm tuaj yeem ua tau raws li cov kev xav tau ntawm cov neeg tsim qauv lossis tswvyim kev tsim qauv los ua qauv.
