Yuav ua li cas tuaj yeem hlau 3D luam kho txhim kho cov txheej txheem hluav taws xob ntawm cov khoom siv hluav taws xob?

Qhov teeb meem ntawm kev ua cov khoom siv hluav taws xob ib txwm muaj zog yam tsis ua rau nws qaug zog
Nws yog ib qho nyuaj ua kom cov txheej txheem nyuaj.
Thaum ua cov khoom siv hluav taws xob nrog cov txheej txheem sab hauv sab hauv cov txheej txheem sab hauv, cov txheej txheem kev ua yeeb yam xws li kev quav dev, thiab ua cov kev ua txhua yam khiav mus ua ntau yam teeb meem. Piv txwv li, lub cav disk ntawm lub dav hlau cav yuav tsum muaj kev cuam tshuam rau hauv nws kom ua haujlwm zoo dua thiab ntev dua hauv kub, nrawm} Taug kev. Txawm li cas los xij, nws yog ib qho nyuaj rau kev tswj kom yog thiab qhov loj me ntawm cov sab hauv nrog cov txheej txheem tsoos. Forging txoj kev tsis tuaj yeem ua kom ncaj qha ua cov hollow thiab complex- cov txheej txheem zoo li yog ib qho nyuaj rau siv ntawm cov qauv sab hauv. Qhov no ua rau nws nyuaj rau kev ua kom zoo ntawm cov txheej txheem lub zog ntawm lub turbine disk.
Txwv kev ua tau zoo ntawm cov ntaub ntawv
Cov ntaub ntawv qauv thiab cov txheej txheem feem ntau yog siv hauv kev tsim khoom qub, uas ua rau nws nyuaj hloov cov khoom ntawm cov ntaub ntawv muaj kev ntxhov siab ntawm cov khoom siv sib txawv ntawm cov khoom siv. Cov khoom sib txawv ntawm cov khoom siv hluav taws xob kev sib txawv thiab cov lus qhia kev ntxhov siab. Txawm li cas los xij, cov khoom siv cov khoom siv feem ntau siv tsuas yog ib qho khoom siv thiab muaj kev faib khoom uas muaj kev sib raug zoo. Qhov no txhais tau tias qee thaj chaw muaj cov kev ua tau zoo dhau lawm, thaum muaj kev ntxhov siab ntau {}} Cov kabmob yuam kev yuav tsis muaj txaus siv cov ntaub ntawv 'muaj peev xwm ua kom muaj zog dua. Piv txwv li, laum me ntsis kev sib txuas ib feem ntawm cov roj dr drilling tau muaj peev xwm los ua kom tau ntau lub zog thiab nro. Txawm li cas los xij, cov khoom siv ntawm kev sib txuas me me sib txuas yog cov tseem ceeb faib thiab tsis tuaj yeem ua kom muaj zog los lis cov kev ntxhov siab tshwj xeeb ntawm ntu no.
Nws yog ib qho nyuaj kom tsis txhob muaj kev tsis xws luag nyob rau hauv kev tsim khoom.
Hauv cov qauv kev ua yeeb yam, cov teeb meem suav nrog porosity thiab shrinkage thaum lub sij hawm casting, folding thaum nco qab, thiab khawb rau saum npoo thaum lub tshuab ua haujlwm muaj ntau. Cov flaws yuav dhau los ua cov cheeb tsam uas muaj kev ntxhov siab, uas yuav ua rau cov qauv tsis muaj zog thiab ua kom cov khoom siv luv luv lub neej. Sij hawm dhau mus, cov flaws hauv cov khoom siv hluav taws xob tej zaum yuav mob heev ntxiv, uas tuaj yeem ua rau lub system tawg. Piv txwv li, thaum ua cov hlab ntsha siab rau cov nroj tsuag hluav taws xob nuclear, txawm tias muaj cov hluav taws xob ntau dua thiab lub siab, uas tuaj yeem ua rau lub zog nuclear hwj chim tsawg dua kev khiav.
Lub tswv yim tom qab hlau 3D luam tawm yog ua kom lub zog khoom zog zog.
Ua kev nyuaj rau kev pub dawb
Cov haujlwm siv tshuab hlau 3D ntxiv ntxiv rau tsim cov khoom los ntawm cov ntaub ntawv stacking nyob rau sab saum toj ntawm ib leeg. Qhov no txhais tau tias cov pwm tsis tuaj yeem xav tau, uas ua rau nws ua rau ua kom muaj peev xwm ua kom muaj peev xwm ua kom cov khoom siv hluav taws xob nrog cov txheej txheem sab hauv. Kev tsim tawm dawb cia cov tsim qauv tsim cov qauv zoo tshaj plaws raws li ntau npaum li cas cov khoom siv yuav tau nrog thiab cov kev xav tau ua tau zoo li cas. Piv txwv li, cov qauv tsim uas tau tsim kev siv cov txheej txheem los ua kom ua kom tau zoo dua tuaj yeem ua ntais ntais thaum tseem ua kom muaj zog txaus. Thaum ua cov qauv txhawb nqa rau cov khoom siv hluav taws xob, cov luam ntawv 3D tau siv los ua qhov chaw uas muaj cov phiaj xwm uas muaj cov duab ntxig. Cov qauv no tsis yog lub teeb xwb, tab sis lawv kuj yuav kis tau kev ntxhov siab sib npaug thiab ua kom cov qauv muaj zog dua.
Hloov cov yam ntxwv ntawm cov ntaub ntawv
Hlau 3D luam ntawv cia koj hloov microstructure ntawm cov khoom siv los ntawm hloov tej yam xws li laser fais fab, ntsuas tuab, thiab lwm yam kev luam ntawv. Qhov no cia koj tau txais qhov zoo uas koj xav tau nyob rau hauv cov khoom siv. Cov noob nplej loj, kev taw qhia, thiab theem muaj pes tsawg leeg ntawm cov ntaub ntawv tuaj yeem hloov pauv kom lawv sib txawv cov khoom siv rau cov khoom siv hluav taws xob sib txawv uas yuav tsum tau daws kev ntxhov siab. Piv txwv li, los ntawm kev hloov lub tshuab luam ntawv, cov khoom siv tuaj yeem ua kom muaj zog dua thiab nyuaj rau hauv qhov uas muaj kev ntxhov siab ntau. Hauv cov cheeb tsam uas yuav tsum tau tawv, cov chaw tuaj yeem hloov pauv kom cov khoom siv tau sib xyaw ua ke, uas yog ua kom cov khoom siv gradient {} d ua rau cov khoom siv txawm muaj zog dua thiab zoo dua.
Qis dua tus naj npawb ntawm cov yuam kev hauv kev tsim khoom
Thaum hlau yog 3D luam tawm, nws yog ua tiav rau hauv lub tshuab nqus tsev lossis cov roj hauv cov cua. Qhov no pab kom txo qhov ceeb toom zoo li porosity thiab shrinkage uas tuaj yeem tshwm sim hauv cov txheej txheem ua yeeb yam. Nyob rau tib lub sijhawm, vim tias cov ntaub ntawv tau muab khi rau saum txheej ntawm ib leeg hauv cov khaubncaws sab nraud ntawm txhua lwm yam hauv cov khaubncaws sab nraud povtseg, txhua txheej tuaj yeem kuaj xyuas kom zoo thiab kho kom sai thiab kho cov teeb meem tau. Tsis tas li, cov nplaim hluav taws xob zoo ntawm qhov ua nrog 3D luam ntawv yog qhov zoo dua, yog li muaj cov khawb thiab lwm yam flaws uas tuaj yeem tshwm sim thaum seem yog ua siv tshuab. Hlau 3D Printing yuav zoo heev txhim kho lub zog thiab qaug zog lub neej ntawm cov khoom siv zog los ntawm kev txo qis cov khoom pov tseg.
Cov teeb meem thiab cov Ntsiab Lus Hlau 3D luam tawm yog kev sib tw
Hlau 3D Luam Ntawv muaj ntau cov lus cog tseg rau kev ua cov khoom siv zog ua kom muaj zog dua, tab sis nws tseem muaj teeb meem daws tau. Piv txwv li, tus nqi siab ntawm cov cuab yeej luam ntawv ua rau nws nyuaj siv rau loj- nplai ntau lawm. Cov hom thiab cov khoom ntawm cov ntaub ntawv luam ntawv tseem yuav tsum tau txhim kho kom tau raws li cov kev xav tau ntawm cov khoom siv hluav taws xob zoo li kev kub siab, thiab corrosion tsis kam. Thaum kawg, cov cuab yeej tswj tau zoo thiab kev soj ntsuam cov thev naus laus zis siv thaum lub sijhawm luam ntawv tsis zoo tag nrho, uas tuaj yeem cuam tshuam qhov zoo thiab kev ntseeg tau ntawm cov seem.
Npaj rau cov lus teb
Txhawm rau tshaj cov teeb meem no, peb yuav tsum muaj kev tshawb fawb thiab kev txhim kho hauv thev naus laus zis. Ntawm ib sab tes, muab nyiaj ntxiv rau hauv kev tshawb fawb thiab kev txhim kho cov tshuab luam ntawv tuaj yeem txo qis cov tshuab, ua rau lawv ruaj khov dua, thiab ua ntau dua ntau dua. Ntawm qhov tod tes, peb yuav txhim kho cov kev tshawb fawb thiab kev nthuav dav cov ntaub ntawv luam tawm, tsim cov khoom siv hlau ntxiv uas ua haujlwm tau zoo, thiab ua tiav cov kev xav tau tshwj xeeb ntawm cov khoom siv zog tshwj xeeb. Nyob rau tib lub sijhawm, peb yuav txhawb kev tswj hwm zoo thiab sim cov qauv kev ua haujlwm zoo, thiab kev siv cov txheej txheem ua kom zoo nkauj kom paub tseeb tias lawv muaj txiaj ntsig zoo thiab yuav ua haujlwm. Nws tseem ceeb heev los tsim cov peev xwm tshaj lij thiab kev ua haujlwm zoo thiab txhawb kev siv cov khoom siv hlau 3D tshuab hauv lub zog khoom siv.
