Nyob rau hauv lub realm ntawm manufacturing, innovation yeej ib txwm yog lub hauv paus ntawm kev vam meej. Nyob rau hauv xyoo tas los, peb tau pom ntau yam kev hloov kho thev naus laus zis uas tau hloov kho thaj chaw ntawm kev tsim khoom. Ntawm cov kev nce qib no, ib lub thev naus laus zis sawv tawm los ua qhov muaj peev xwm hloov pauv kev ua si: Xaiv Laser Melting (SLM) 3D luam ntawv.
SLM 3D luam ntawv yog cov txheej txheem kev tsim khoom siv hluav taws xob uas siv cov lasers uas muaj zog los xaiv cov yaj thiab fuse hlau hmoov txheej los ntawm txheej, tsim cov khoom zoo sib xws thiab cov khoom peb sab. Cov thev naus laus zis no muaj ntau qhov zoo dua li kev tsim khoom ib txwm muaj, ua rau nws muaj kev xaiv zoo rau ntau yam lag luam.
Ib qho tseem ceeb tshaj plaws ntawm SLM 3D luam ntawv yog nws lub peev xwm los tsim cov geometry nyuaj nrog qhov tsis sib xws. Cov txheej txheem tsim khoom qub feem ntau tawm tsam nrog cov qauv tsim tshwj xeeb vim muaj kev txwv hauv kev siv cuab yeej thiab kev siv tshuab. Txawm li cas los xij, nrog SLM 3D luam ntawv, yuav luag txhua tus qauv tuaj yeem muab txhais ua ib qho khoom siv nrog kev txwv tsawg. Qhov no qhib qhov muaj peev xwm tshiab rau cov khoom tsim kho tshiab thiab kev hloov kho, tso cai rau cov tuam txhab tsim cov khoom thiab cov qauv uas yav tas los suav tias tsis ua tau.
Tsis tas li ntawd, SLM 3D luam ntawv muaj kev txhim kho tseem ceeb hauv kev ua haujlwm thiab kev ua haujlwm tau zoo. Los ntawm kev tshem tawm qhov xav tau ntawm cov cuab yeej siv ib txwm siv thiab txo cov khoom pov tseg, cov tuam ntxhab tuaj yeem hloov kho lawv cov txheej txheem tsim khoom thiab ua tiav cov nqi txuag nyiaj ntau. Tsis tas li ntawd, lub peev xwm los sib sau ua ke ntau yam khoom siv rau hauv ib qho kev sib txuas ntxiv txo cov sij hawm sib dhos thiab txo qis tag nrho cov nqi tsim khoom. Qhov kev ua tau zoo no tuaj yeem ua tau zoo tshwj xeeb hauv kev lag luam uas lub sijhawm-rau-kev ua lag luam thiab kev sib tw nqi yog qhov tseem ceeb.
Lwm qhov txiaj ntsig tseem ceeb ntawm SLM 3D luam ntawv yog nws cov khoom siv ntau yam hauv kev xaiv. Tsis zoo li kev tsim khoom ib txwm siv uas feem ntau txwv rau cov ntaub ntawv tshwj xeeb, SLM thev naus laus zis tuaj yeem ua tiav ntau yam ntawm cov hmoov hlau, suav nrog titanium, stainless hlau, aluminium, thiab txawm tias cov khoom sib txawv. Qhov kev ua tau zoo no tso cai rau cov tuam txhab tsim kho cov khoom siv ntawm lawv cov khoom kom tau raws li cov kev cai tshwj xeeb ntawm lawv cov ntawv thov, txawm tias nws yog lub zog, kev tiv thaiv corrosion, lossis thermal conductivity. Yog li ntawd, SLM 3D luam ntawv tau nce zuj zus hauv kev lag luam xws li aerospace, tsheb, thiab kev kho mob, qhov twg cov ntaub ntawv kev ua tau zoo yog qhov tseem ceeb.
Tsis tas li ntawd, SLM 3D luam ntawv tso cai rau kev tsim khoom raws li qhov xav tau, txo qhov xav tau ntawm cov khoom lag luam loj thiab chaw rau khoom. Nrog rau txoj kev tsim khoom ib txwm muaj, tuam txhab lag luam yuav tsum kwv yees qhov xav tau thiab tsim cov khoom lag luam nyob rau hauv kev cia siab ntawm kev txiav txim yav tom ntej, feem ntau ua rau overstocking los yog tsis txaus. Hauv qhov sib piv, SLM thev naus laus zis tso cai rau kev tsim khoom sai ntawm cov khoom hauv kev teb rau cov kev xav tau tiag tiag, txo qis cov nqi tuav khoom thiab ua kom cov khoom lag luam muaj zog. Qhov kev tsim khoom lag luam no tsis yog tsuas yog txo qis kev pheej hmoo nyiaj txiag tab sis kuj txhim kho kev ua haujlwm yooj yim, ua rau cov tuam txhab hloov pauv sai sai rau kev hloov pauv hauv kev lag luam.
Txawm hais tias nws muaj txiaj ntsig ntau, SLM 3D luam ntawv tsis yog yam tsis muaj qhov nyuaj. Cov cuab yeej siv tshuab yuav tsum muaj cov cuab yeej tshwj xeeb thiab kev txawj ntse, uas tuaj yeem raug nqi kom tau txais thiab tswj xyuas. Tsis tas li ntawd, ua kom tau raws li qhov zoo ib yam thiab rov ua dua nyob rau ntau qhov kev tsim kho tuaj yeem nyuaj, yuav tsum muaj kev tswj xyuas kom zoo thiab ua kom zoo dua qub. Tsis tas li ntawd, cov kauj ruam tom qab ua tiav xws li kev kho cua sov thiab kev ua tiav saum npoo yuav tsim nyog kom ua tau raws li qhov xav tau tshwj xeeb, ntxiv sijhawm thiab nyuaj rau cov txheej txheem tsim khoom.
Txawm li cas los xij, lub peev xwm ntawm SLM 3D luam ntawv los hloov pauv kev tsim khoom tsis tuaj yeem overstated. Raws li cov thev naus laus zis txuas ntxiv txhim kho thiab paub tab, peb tuaj yeem cia siab tias yuav pom kev saws me nyuam thoob plaws ntau qhov kev lag luam, tsav tsheb tshiab thiab hloov kho cov saw hlau. Cov tuam txhab uas tuav SLM 3D luam ntawv thaum ntxov ntawm kev sawv ntsug kom tau txais kev sib tw kom zoo dua ntawm cov khoom tsim, kev ua haujlwm zoo, thiab kev ua haujlwm rau kev lag luam xav tau.
Hauv kev xaus, SLM laser 3D luam ntawv thev naus laus zis sawv cev rau kev hloov pauv hauv kev tsim khoom, muab cov peev txheej tsis sib xws ntawm cov qauv tsim, kev ua haujlwm zoo, thiab cov khoom siv ntau yam. Thaum cov kev sib tw tseem nyob, cov txiaj ntsig muaj peev xwm tshaj qhov tsis zoo, ua rau SLM 3D luam ntawv yog qhov kev xaiv zoo rau cov tuam txhab xav txog yav tom ntej tab tom nrhiav ua ntej hauv kev sib tw thoob ntiaj teb kev lag luam. Thaum peb pib taug kev mus rau yav tom ntej ntawm kev tsim khoom, SLM thev naus laus zis tau npaj los ua lub zog muaj zog, tsav tsheb tshiab thiab hloov pauv kev lag luam hauv txoj hauv kev uas peb tseem tsis tau xav txog.
