Tsim Volume: Ntsuas Qhov Loj thiab Ua Tau Zoo
Nyob rau hauv lub realm ntawm loj industrial 3D tshuab luam ntawv, tsim ntim ntawm 3D tshuab luam ntawv yog ib qho tseem ceeb xav txog. Loj npaum li cas "loj" thiab qhov feem pua ntawm koj cov zis yuav tsum muaj cov ntawv luam loj dua? Tsis tas li ntawd, nws tseem ceeb heev uas yuav tsum tau coj mus rau hauv tus account qhov ceev ntawm kev luam ntawv rau kev ua haujlwm tau zoo. Ua kev tshawb fawb txog Kev Tsim Kho Loj Loj (LFAM) kom nkag siab tias cov thev naus laus zis tshiab ua raws li koj qhov kev xav tau ntawm kev lag luam tshwj xeeb.
Dual Print Head: Ua haujlwm ua haujlwm tau zoo
Lub taub hau luam ntawv dual tuaj yeem ua qhov kev ua si-hloov rau kev ua haujlwm zoo. Lub peev xwm los luam tawm ob qho kev ywj pheej nyob rau hauv cov ntsiab lus muab kev nkag mus ntawm ob lub tshuab luam ntawv hauv ib qho. Tsis tas li ntawd, qee lub tshuab luam ntawv loj tso cai rau ob lub tshuab luam ntawv sib txawv siv nyob rau hauv tib lub sijhawm, muab cov tuam txhab tsim khoom thiab cov neeg tsim khoom muaj peev xwm ua haujlwm ntawm ntau qhov haujlwm ib zaug. Xav txog qhov no, tshwj xeeb tshaj yog tias koj daim ntawv thov xav tau cov ntaub ntawv sib txawv uas tau txais txiaj ntsig los ntawm kev luam ntawv ib txhij. Hom kev hloov pauv thiab nrawm no tuaj yeem muab tus nqi siab ntawm kev lag luam qib.
Printing Infill Support: Streamlining the Production Journey
Tshawb xyuas seb lub tshuab luam ntawv 3D ua haujlwm li cas txhawb nqa cov qauv, vim tias nws cuam tshuam ncaj qha tsis yog tsuas yog luam ntawv lub sijhawm thiab kev siv zog tom qab ua tiav, tab sis kuj yog koj qhov cuam tshuam rau ib puag ncig. Pom tseeb, qhov loj dua feem ntau xav tau cov ntaub ntawv luam tawm ntau dua rau cov qauv kev txhawb nqa thiab sau - ntau yam uas tsis yog siv rau qhov kawg kawg. Saib rau hauv cov thev naus laus zis uas tso cai rau luam tawm ntawm qhov hollow raws li qhov no tuaj yeem txo qis ntawm koj cov khoom pov tseg.
Ntau yam ntawm cov ntaub ntawv: Tailoring rau cov ntawv tshwj xeeb
Ua ntej dhia mus rau hauv cov khoom siv loj, tsim cov npe meej ntawm cov ntawv thov uas koj npaj siab yuav luam tawm kom nkag siab txog kev sib raug zoo nrog koj cov kev xav tau. Txawm hais tias lawv yog cov khoom tsim, pwm, los yog mockups, cov ntaub ntawv luam ntawv yuav tsum tau ua raws li koj cov kev xav tau ntawm cov khoom siv tshuab, cov kev xav tau hloov pauv, thiab cov xwm txheej xws li kev kub siab, kev thauj mus los thiab dej hiav txwv, lossis nplaim hluav taws.
Printing lossis Casting Materials?
Yog tias ib feem ntawm koj cov khoom tso tawm suav nrog cov cuab yeej lossis cov ntawv thov molding, xav txog cov khoom siv kho tshuab xws li CTE (Coefficient of Thermal Expansion) thiab HDT. Kev lag luam loj 3D tshuab luam ntawv tau hloov zuj zus los teb rau cov hnub nyoog kev lag luam kev sib tw nrog rau isotropy. Txog thaum tsis ntev los no, cov thev naus laus zis ntxiv tsis muaj peev xwm ncaj qha luam ntawv isotropic qhov chaw thiab pwm (vim cov txheej txheem 'txheej txheem' txheej txheem cuam tshuam nrog cov thev naus laus zis no.
Smart Cleaning System: Ua kom muaj kev ua haujlwm tsis muaj teeb meem
Lub tshuab ntxuav ntse, ua ke nrog lub khoos phis tawj saib xyuas software, ua kom cov luam ntawv du thiab tsis cuam tshuam. Qhov no tsis siv neeg feature txo qhov kev cia siab ntawm cov neeg ua haujlwm rau kev cuam tshuam, ua rau muaj kev cuam tshuam tsis muaj teeb meem thiab kev luam ntawv zoo ib yam.
Muaj ntau yam ntxiv rau koj lub cuab yeej
Rau ntau lub tuam txhab thiab cov lag luam, cov tshuab luam ntawv loj 3D tsis yog hais txog kev hloov cov thev naus laus zis uas twb muaj lawm, tab sis theej nthuav lawv lub peev xwm. Lawv ua haujlwm ntawm nws tus kheej nrog rau CNC tshuab, phau ntawv txheej txheem, thiab lwm yam cuab yeej, muab cov kev daws teeb meem zoo rau cov haujlwm tshwj xeeb thiab kev siv. Kev sib txuas cov khoom siv ntxiv rau hauv cov txheej txheem tsim khoom yuav tso cai rau cov tuam txhab txiav cov nqi, nce kev ua tau zoo, thiab txhim kho cov khoom kawg.
Loj Muaj 3D tshuab luam ntawv Cov lus qhia txog kev tu txhua tus neeg yuav tsum paub
Yooj Yim Kev Nyuaj Siab
Cov neeg feem coob uas yuav cov tshuab luam ntawv loj 3D xav tias lawv yuav tsis tshua muaj kev txhawj xeeb txog kev saib xyuas thaum lawv teeb tsa lub tshuab. Txawm li cas los xij, qhov ntawd tsis yog qhov xwm txheej thaum nws los txog rau txoj siv tawv. Cov ntsia hlau tuav txoj hlua khi txoj hlua khi rau hauv qhov chaw zoo li tuaj yeem xoob lub sijhawm, ua rau cov ntawv luam tawm tawm ntawm whack.
Yog li ntawd, koj yuav tsum khaws cov ntsia hlau no ruaj ntseg-tab sis tsis yog ntau npaum li koj ntxiv kev ntxhov siab ntau dhau. Tus nqi zoo meej yog ruaj txaus los tuav txoj siv rubey. Txhua yam dhau los lossis qis dua uas tuaj yeem ua rau muaj teeb meem.
Ntxuav Cov Ntxuam
Ib qho ntawm cov nqi qis tshaj plaws ntawm 3d-lub tshuab luam ntawv tu yog tu cov kiv cua. Cov kiv cua cuam tshuam rau cov khoom kawg vim tias qhov kub thiab txias npaum li cas rau 3d luam ntawv. Kev ua tsis tiav rau qhov kev saib xyuas no yuav cuam tshuam tsis zoo rau kev luam ntawv.
Clogging thiab stringing tuaj yeem tshwm sim yog tias lub kiv cua kub kawg ua qias neeg. Tsis tu ncua txhuam cov kiv cua ntawm koj lub tshuab luam ntawv 3D loj tuaj yeem txuas ntxiv lawv lub neej thiab txuag koj cov nyiaj los ntawm kev tiv thaiv kev kho kim.
Tiv thaiv Clogging
Filament blockages yog cov teeb meem raug nrog cov tshuab luam ntawv 3D loj. Yog tias lub nozzle raug thaiv, lub tshuab luam ntawv yuav tsum tsis txhob siv cov khoom siv extruding, thiab kev tsim yuav raug kaw lossis, qhov phem dua, txuas ntxiv luam cov txheej txheem tshiab. Kev puas tsuaj rau lub tshav kub tiv thaiv los ntawm ib qho me me ntawm cov khoom molten kuj ua tau.
Cov cim qhia ntawm cov filament blocked muaj xws li curvatures nyob rau hauv cov khoom luam tawm thiab ib tug uas ploj lawm los yog darkened tshav kub ntaub thaiv npog. Sandpaper los yog tooj dag hlau txhuam tuaj yeem tshem tawm qhov ntau dhau, qhib lub nozzle kom lub tshuab ua haujlwm txuas ntxiv nws cov khawv koob.
Lube Qhov Tseem Ceeb
Lwm cov kauj ruam tseem ceeb hauv kev lag luam loj 3D tshuab luam ntawv tu yog ntxuav thiab lubricate cov bearings thiab linear rails. Lubricating lub txav qhov chaw yuav tsim nyog yog tias koj hnov squeaks lossis hnov txog kev tawm tsam; txwv tsis pub, koj yuav tsum roj cov khoom tom qab li 1, 000 teev ua haujlwm.
Txhawm rau siv cov roj los yog roj nplua nyeem rau qhov txav ntawm qee lub tshuab luam ntawv, koj yuav tsum so cov pas nrig kom huv, siv cov roj, thiab tom qab ntawd rov nruab lawv.
Nruab Firmware Hloov tshiab
Kev yuav lub tshuab luam ntawv loj loj 3D los ntawm lub tuam txhab paub zoo, muaj npe nrov xav kom koj nyob twj ywm rau txhua lub firmware hloov khoom dua tshiab los kho cov kab thiab ntxiv cov yam ntxwv tshiab. Yog tias muaj dab tsi ua tsis zoo, paub yuav ua li cas tswj lub Hoobkas firmware yuav tuaj yeem ua ke. Tsis tas li ntawd, kev hloov kho firmware tsis yog ib yam dab tsi uas koj tuaj yeem suav nrog cov peev nyiaj loj hauv 3D tshuab luam ntawv, yog li nws yog qhov zoo tshaj los nrhiav kev hloov tshiab rau koj cov qauv hauv online.
Lub tshuab luam ntawv loj 3D ua haujlwm li cas?
Kawm paub ntau npaum li cas cov tshuab luam ntawv 3D ua haujlwm thiab muaj peev xwm tsim cov khoom 3D los ntawm ntau txoj kev luam ntawv thiab thev naus laus zis.
Muaj ntau tshaj li kaum ob hom ntawm 3D luam ntawv txheej txheem siv niaj hnub no. 3D luam ntawv tau pib thaum xyoo 1980s los hloov cov qauv tsim thiab cov qauv tsim los ntawm cov ntoo lossis dai ua ke los ntawm daim npav lossis yas.
3D luam ntawv yog ib qho laj thawj txuas ntxiv ntawm kev tsim qauv sai sai (qhov twg cov qauv thiab cov qauv tsim los ntawm cov txheej txheem automated). Qhov tshwm sim yog txuag lub sijhawm thiab nyiaj txiag. 3D luam ntawv tau nthuav dav rau engineering, kev tsim khoom, kev lag luam thiab kev siv tus kheej.
3D luam ntawv yog ua tiav los ntawm kev tsim khoom ntxiv - cov txheej txheem los ntawm cov khoom siv tau koom nrog hauv kev tswj hwm lub computer los tsim cov khoom peb sab. Cov khoom, xws li cov kua resin mus rau hmoov nplej, yog fused ua ke txheej los ntawm txheej. Ntau yam duab, suav nrog cov txheej txheem nyuaj, tau yooj yim luam tawm los ntawm cov qauv 3D lossis CAD cov ntaub ntawv.
Kev tsim khoom ntxiv yog qhov sib txawv ntawm kev tsim tawm, uas tshem tawm ntawm ib qho khoom. Hauv lwm lo lus, cov tshuab luam ntawv loj 3D ua haujlwm los ntawm kev tsim cov qauv peb sab ib txheej ntawm ib lub sijhawm, los ntawm hauv qab mus rau sab saud.
