Hlau 3D luam ntawv yog ib qho kev siv thev naus laus zis ntawm digital thermal ua. Tam sim no 3D luam ntawv thev naus laus zis rau kev npaj cov hlau feem ntau suav nrog: Xaiv Laser Melting (SLM), Electron Beam Selective Melting (EBSM), Laser Near Net Shaping (LENS), thiab lwm yam.
Niaj hnub no, xaiv laser melting (SLM) yog siv dav tshaj plaws. Cov khoom siv feem ntau siv hauv cov thev naus laus zis no yog cov qib high-qib thiab kim titanium alloys, pheej yig stainless hlau, thiab nruab nrab tsim aluminium alloys. Ib tiam ntawm cov khoom siv, ib tiam ntawm cov khoom siv, qhov zoo thiab qhov tseeb ntawm cov khoom ua los ntawm cov khoom sib txawv yog txawv, thiab lawv cov kev siv kuj txawv.
Raws li cov khoom siv tseem ceeb rau 3D luam ntawv ntawm cov khoom siv hlau, qhov zoo ntawm cov hmoov hlau loj txiav txim siab qhov kawg molding nyhuv ntawm cov khoom. Yog li ntawd, cov hmoov zoo yog qhov tseem ceeb heev rau kev tsim cov hlau 3D tshuab luam ntawv. Raws li qhov yooj yim, ncaj qha thiab cov khoom tseem ceeb ntawm cov hlau 3D luam ntawv, cov ntaub ntawv hmoov yog cov khoom zoo, cov hmoov tsis tshua muaj nqi.
Raws li hom tshiab ntawm cov khoom siv hlau hnyav, titanium thiab titanium alloys tau siv dav hauv aerospace, roj av zog, nkoj tsim, tshuaj lom neeg, tshuaj lom neeg, kev kho mob thiab lwm yam kev lag luam nrog cov khoom zoo heev xws li lub zog tshwj xeeb thiab zoo corrosion kuj. Raws li cov txheej txheem tseem ceeb thiab kev tshawb fawb hotspot ntawm hlau 3D luam ntawv, 3D luam ntawv titanium alloy tuaj yeem tsis tsuas yog txhim kho cov khoom siv, tab sis kuj daws cov teeb meem nyuaj ntawm titanium alloy ua nyuaj rau yaj thiab yooj yim rau paug.
Nyob rau hauv xyoo tas los no, nrog kev loj hlob tsis tu ncua thiab kev txhim kho ntawm 3D tshuab luam ntawv, titanium 3D luam ntawv tau dhau los ua cov khoom tshawb fawb tseem ceeb hauv thaj chaw aerospace. Noj titanium alloys rau aerospace ua piv txwv, 3D luam ntawv tuaj yeem txuag tau 30% ntawm cov ntaub ntawv piv nrog cov txheej txheem ib txwm muaj. Tus nqi, qee qhov 3D luam tawm titanium alloy loj thiab nyuaj qhov chaw tau ua tiav engineering pov thawj hauv kev tsim tsheb thiab kev dav hlau.
Vim yog biocompatibility zoo, 3D luam ntawv titanium-raws li cov ntaub ntawv kuj tau siv dav hauv kev kho mob. Tus neeg mob cov ntaub ntawv CT scan tau ua qauv ntxiv, thiab tus kheej prostheses yog tsim thiab tsim los ntawm 3D tshuab luam ntawv. Nws tau siv rau hauv kev kho mob hauv tsev thiab txawv teb chaws. Txiv hmab txiv ntoo tau tiav lawm. Muaj ntau qhov kev vam meej ntawm 3D luam ntawv pob txha taub hau, sternums, hniav, pob qij txha, thiab lwm yam hauv kev ua haujlwm kho mob, thiab qee cov khoom uas sawv cev los ntawm acetabular khob tau tsim tawm ntau.
Kev npaj cov khoom siv hlau-raws li kev ua haujlwm siab yog tam sim no lub hom phiaj ntawm kev tshawb fawb hauv tsev thiab txawv teb chaws. Vim muaj ntau qhov chaw thiab cov nqi qis, cov khoom siv hlau hlau uas sawv cev los ntawm cov khoom siv hlau tsis muaj steel yog ib qho ntawm cov khoom siv hlau thaum ntxov uas siv hauv 3D luam ntawv, thiab tau kawm dav thiab siv hauv kev lag luam 3D luam ntawv.
Piv nrog rau cov tsoos casting thiab forging tshuab, 3D luam ntawv stainless hlau muaj zoo heev lub cev, tshuaj thiab txhua yam khoom xws li siab zog, zoo heev kub tsis kam, hnav tsis kam thiab corrosion kuj, thiab lwm yam., ua ke nrog siab qhov tseeb thiab cov khoom siv, hauv aviation. Nws yog dav siv nyob rau hauv aerospace, tsheb, shipbuilding, machinery manufacturing thiab lwm yam lag luam.
Vim nws qhov kev ua tau zoo ntawm qhov kub thiab txias, zoo heev corrosion kuj thiab hnav tsis kam, superalloys yog tsim rau cov kev pab cuam mus sij hawm ntev nyob rau hauv huab cua kub, kub siab vibration thiab corrosion. Lawv yog siv nyob rau hauv aerospace, automotive engine hniav, stators, combustion chambers, thiab lwm yam. Turbine disks thiab txiav cov cuab yeej, thee fais fab, nuclear fais fab nroj tsuag, roj av thiab lwm yam teb yog dav nyiam los ntawm scientific researchers.
Raws li ib qho tseem ceeb ntawm cov khoom siv hnyav hnyav, aluminium alloy feem ntau muaj qhov zoo ntawm lub teeb yuag, siab zog, zoo plasticity, thiab corrosion kuj. Nws ua lub luag haujlwm tseem ceeb hauv thaj chaw aerospace, tsheb, thiab nkoj. Txoj kev loj hlob ntawm aluminium alloy 3D tshuab luam ntawv tau dhau los ua kev tshawb fawb Ib qho ntawm cov chaw kub. Vim muaj cov khoom zoo heev xws li tus nqi qis, lub sijhawm luv luv, siab precision, tsis xav tau pwm, thiab net molding, 3D tshuab luam ntawv tau los ua thaum cov cuab yeej siv niaj hnub tsis tuaj yeem ua tau raws li lub teeb yuag thiab kev tsim khoom ntawm cov khoom sib xyaw ua ke. .
Kev tshawb fawb tau qhia tias 3D printing txhuas alloys peev xwm ua tau tuab qhov chaw, zoo lug, thiab txhua yam khoom piv rau castings los yog zoo dua tshaj casting molded qhov chaw. Piv nrog rau cov txheej txheem ib txwm muaj, nws qhov zoo tuaj yeem raug txo los ntawm 22%, tab sis nws cov nqi yuav raug txo los ntawm 30%. Tsis tas li ntawd, cov khoom siv hlau thiab hlau xws li Cu thiab Mg. Sn kuj tau txais kev kawm dav dav thiab siv rau hauv kev lag luam aviation, kev lag luam tub rog, tsheb, thiab kev kos duab.
