Thaum lub xyoo no TCT Asia 3D Printing Exhibition thiab Zhuhai Cua Show, "mass manufacturing" tau dhau los ua cov lus tseeb los piav qhia txog hlau 3D tshuab luam ntawv. "Kev muaj peev xwm ntau dua rau kev tsim khoom loj ntawm aerospace qhov chaw" thiab "rau kev tsim khoom loj" tsis tsuas yog ua rau peb xav tsis thoob, puas yog hlau 3D luam ntawv tsim sai thiab txhim khu kev qha?
Qhov laj thawj rau tus tswv lag luam los tshaj tawm cov lus tshaj tawm yog vim muaj cov xwm txheej txhim khu kev qha los txhawb qhov kev hais lus no. Tus neeg sawv cev zoo tshaj plaws yog tias GE Aviation tau ua tiav kev tsim khoom ntau dua 100, 000 lub taub hau nozzle thiab siv lawv mus rau cov tshuab siab tshaj plaws:
GE9X ntawm Boeing 777X
LEAP-1A ntawm Airbus A320 NEO
LEAP-1B nqa los ntawm Boeing 737MAX
LEAP-1C ntawm Suav C919
Nws ua ke 20 qhov chaw ua los ntawm vuam rau hauv qhov tseeb tag nrho, uas txo qhov hnyav ntawm cov khoom los ntawm 25 feem pua piv rau cov tiam dhau los, txhim kho durability los ntawm 5 zaug, thiab nce tus nqi-zoo los ntawm 30 feem pua. Nws cov qauv tsim tshwj xeeb xav tau tsuas yog Nws tuaj yeem tsim los ntawm 3D txheej txheem luam ntawv. Qhov kev vam meej ntawm cov ntaub ntawv no qhia tau hais tias hlau 3D luam ntawv yog ua tau rau ntau lawm.
Txawm hais tias cov xwm txheej hauv tsev ntawm kev tsim khoom loj ntawm hlau 3D luam ntawv hauv aerospace teb tsis tau luam tawm, cov lus qhia tseem tuaj yeem ntes tau. Hauv daim ntawv thov zaum kawg ntawm Lub Tsev Kawm Ntawv Sixth ntawm Aerospace Science thiab Technology, nws tau hais tias nyob rau hauv kev tsim kho thiab tsim cov txheej txheem ntawm 85-tuj qhib-kho cov pa roj carbon monoxide cav, "cov khoom tseem ceeb ntawm 3D luam ntawv tau raug. sim kaum ob lub sij hawm nyob rau hauv lub sij hawm ntev kev ntsuam xyuas. " Qhov no ua pov thawj los ntawm sab uas qhov zoo ntawm cov khoom tsim los ntawm hlau 3D tshuab luam ntawv yog txhim khu kev qha thiab tuaj yeem lees txais los ntawm aerospace teb. Tom ntej no, los ntawm qhov kev xav ntawm kev tsim khoom, dab tsi cuam tshuam rau kev tsim khoom loj hauv aerospace sector yuav raug piav qhia.
1. Cov khoom sib xws, yog qhov tseem ceeb rau kev tsim khoom dua
Lub realization ntawm batch manufacturing txhais tau hais tias txhua qhov chaw tsim los ntawm hlau 3D luam ntawv nyob rau hauv ib tug batch los yog nyob rau hauv ntau batch yog tag nrho raws li ib feem ntawm qhov zoo, kev ua tau zoo, thiab qhov tseeb qhov ntev, uas yog, lub tshuab tau ua tiav kev tsim khoom zoo. Qhov no tso cai nruj rau cov khoom siv luam ntawv thiab cov txheej txheem txheej txheem.
Kev kho ntawm cov cuab yeej yuav tsum tau ua raws li cov qauv nruj thiab muaj peev xwm ua tiav kev tsim khoom zoo dua qub, kom muaj cov txheej txheem yooj yim rau ntau lawm. Tab sis qhov no tsuas yog ib qho kev piav qhia, tab sis nws suav nrog ntau yam, xws li kev tshem tawm cov pa luam yeeb thiab kev tswj hwm huab cua hauv qhov chaw tsim khoom thaum lub sij hawm luam ntawv, kev ruaj ntseg ntawm lub zog laser, thiab kev tswj hwm lub zog ntawm txhua feem ntawm lub platform nyob rau hauv ib qho kev pom zoo, luam ntawv Cov ntsiab lus oxygen tswj nyob rau hauv lub chamber thiab tom qab ua tiav yuav tsum tau tom qab kev tsim kho tiav, thiab lwm yam, tus naj npawb ntawm cov sensors uas yuav tsum tau teem caij tuaj yeem ncav cuag ntau txhiab. GE kuj tau ua tiav cov kev tshawb fawb, kev tsom xam, thiab kev hloov pauv ntawm lub tshuab luam ntawv Concept Laser kom tau raws li lub peev xwm ntawm kev tsim khoom loj.
2. Cov kws ua haujlwm tau zoo yog qhov tseem ceeb
Rau hlau 3D tshuab luam ntawv, ntau yam kev paub txog kev ua haujlwm yuav tsum tau ua, tab sis nws tsis tas yuav tsum muaj ib tus neeg ua ntau yam txuj ci. Cov thev naus laus zis no suav nrog ntau cov ntsiab lus, xws li tsim rau kev tsim khoom ntxiv, kev ua haujlwm thiab kev saib xyuas, kev tsim cov txheej txheem luam ntawv thiab kev tswj cov khoom zoo, tom qab ua tiav, thiab lwm yam.
Yuav luag tag nrho cov txheej txheem kev koom tes no yuav cuam tshuam ncaj qha seb qhov kev tsim khoom ntawm cov khoom zoo li cas. Rau cov neeg muag khoom tau cog lus los muab kev pabcuam rau kev lag luam aerospace, cov txuj ci hauv cov kev sib txuas no yog qhov tseem ceeb, tshwj xeeb tshaj yog cov kws tshaj lij engineers. Tsim cov engineers nrog cov kev txawj tshwj xeeb no yog kim thiab siv sijhawm, tab sis tsim nyog.
3. Cov nqi tsim khoom yuav tsum txo qis mus ntxiv
Nws yuav tsum tau taw qhia tias 3D luam ntawv thev naus laus zis yuav tsis raug siv dav thiab tsim khoom loj tshwj tsis yog tias qhov rov qab los ntawm kev nqis peev ntau dua lwm txoj hauv kev tsim khoom. Rau aerospace teb, tus nqi tsis zoo li yog qhov tseem ceeb tshaj plaws, tab sis tus nqi tseem cuam tshuam seb puas tuaj yeem ua tiav.
Tus nqi siab ntawm lub tshuab nws tus kheej yog qhov teeb meem loj. Txawm li cas los xij, tom qab kaum xyoo ntawm kev siv thev naus laus zis thiab R & D rov ua dua, cov cuab yeej siv ntawm 3D tshuab luam ntawv tau poob qis heev piv rau cov hnub qub. Ib yam li ntawd, muaj qhov sib xws ntawm cov nqi khoom siv. Tsis muaj teeb meem los ntawm kev xav ntawm cov cuab yeej paub tab lossis los ntawm kev xav ntawm kev sib tw, kev txo qis ntawm cov nqi tsim khoom yuav raug inevitable.
4. Yuav muaj ntau thiab ntau qhov kev hloov kho tsis siv neeg thiab ntau lawm
Kev txo qis tib neeg kev ua yuam kev yog qhov tseem ceeb heev rau kev tsim cov khoom siv hlau. Piv txwv li, thaum kho qhov tsis sib xws ntawm qhov chaw loj thiab ntau lub laser sib tshooj, qhov kev txiav txim ntawm cov engineers yuav txawv. Yog li ntawd, qee cov tuam txhab lag luam xws li Farsoon Hi-Tech nws tus kheej tsim "Multi-laser ntse calibration system" uas daws qhov kev sib tw ntawm ntau lub laser overlapping sib xws mus rau qhov loj tshaj plaws, ua rau kev luam ntawv zoo thiab kev ua tau zoo dua qub.
Lwm yam kev ua yuam kev ntawm tib neeg muaj xws li kev txhim kho cov substrates, hmoov ntxuav ntawm cov kav dej hauv qhov chaw, thiab txhawb kev tshem tawm thiab tom qab ua tiav. Tam sim no software thiab kho vajtse ua rau cov txheej txheem no ntse dua. Txawm hais tias tam sim no degree ntawm automation tseem txwv, nws tuaj yeem pom tias qhov no yuav yog qhov sib txawv.
Cov ntsiab lus
Daim ntawv thov zoo ntawm hlau additive manufacturing technology nyob rau hauv lub aerospace teb muaj xws li liberated tsim, siab siv cov khoom, tsawg raug nqi, thiab ceev manufacturing. Tom qab muaj kev tsis ntseeg thaum ntxov, nws pib tsim sai heev.
Hlau 3D luam ntawv tsis yog tsuas yog "tuaj yeem luam tawm", qhov kev ua tau zoo yuav tsum ua kom tau raws li qhov xav tau ntawm kev teeb tsa, ntau lawm yuav tsum ruaj khov, ua haujlwm zoo, thiab zoo ib yam, tus nqi yuav tsum tau txo qis, thiab kev tsim kho tshiab muaj peev xwm ntawm kev tsim thiab kev txhim kho thiab kev txhim kho. yuav tsum tau txhim kho ntxiv. Tsuas yog nyob rau hauv txoj kev no nws tuaj yeem dhau los ua ib feem tseem ceeb ntawm kev tsim khoom lag luam, thiab qhov no ib zaug "tsis yog lub ntsiab" txheej txheem tuaj yeem muaj sia nyob rau lub caij ntuj no txias.
