Cov kev lag luam twg muaj cov kev xav tau siab tshaj plaws rau qhov tseeb ntawm cov hlau 3D luam ntawv?

1. Aerospace: Kev ua si nrog millimeter-theem precision nyob rau hauv hnyav heev
Lub dav hlau sector yog "highland" siv hlau 3D tshuab luam ntawv. Cov kev xav tau tseem ceeb yog rau kev sib xyaw molding ntawm cov qauv nyuaj thiab ua kom lawv ua haujlwm hnyav. Piv txwv li, qhov kub thiab txias ua haujlwm ntawm aviation cav hniav tuaj yeem nce mus txog 1500℃, thiab lawv yuav tsum muaj peev xwm tswj tau siab - nrawm tig kev ntxhov siab ntawm kaum tawm txhiab tus kiv puag ncig ib feeb. Ib qho kev hloov me me ntawm qhov loj tuaj yeem ua rau lub zog tshem tawm ntawm cov hniav thiab cov vaj tsev tsis muaj kev tswj hwm, uas tuaj yeem ua rau muaj kev puas tsuaj loj.
Yuav tsum muaj rau qhov tseeb:
Dimensional kam rau ua: Qhov ntev kam rau ua rau qhov tseem ceeb xws li roj injectors thiab turbine hniav yuav tsum tau khaws cia nyob rau hauv ± 0.02mm. Qee qhov chaw mating tej zaum yuav xav tau nyob rau hauv ± 0.01mm.
Roughness ntawm qhov chaw: Qhov chaw ua haujlwm roughness yuav tsum tsawg dua Ra0.8 μ m kom airflow ntawm kev sib cais thiab thermal stress ntawm lub tsev.
Geometric kam rau ua: Txhawm rau kom paub tseeb tias qhov kev ua haujlwm aerodynamic phim tus qauv tsim, qhov yuam kev ntawm contour ntawm qhov chaw nyuaj yuav tsum tsawg dua 0.05 hli.
Yuav ua li cas technically:
Laser Selective Melting (SLM): A 20-60 μm nyias txheej ntawm cov hmoov thiab ib lub micrometer- laser qhov chaw yog siv los ua siab - pwm precision. Lub titanium alloy central tis ntug strip uas Platinum Lite tsim rau lub dav hlau C919, piv txwv li, muaj qhov tseeb qhov tseeb ntawm ± 0.05mm thiab qhov roughness ntawm Ra3.2 μ m. Tom qab electropolishing, qhov nto roughness yog txo mus rau Ra0.4 μ m.
Ntau- laser kev sib koom tes scanning: ua hauj lwm 4 mus rau 8 lasers uas nyob rau hauv sync los txiav down ntawm distortion tshwm sim los ntawm tshav kub kev ntxhov siab. Liantai Technology xa cov hlau nyias nyias mus rau ib chav dav hlau. Phab ntsa thinnest yog 0.25mm tuab thiab kam rau ua tsuas yog 0.075mm. Qhov no qhia tau tias ntau -laser system ruaj khov.
Kaw lub voj kev tawm tswv yim tswj: Los ntawm kev ua kom lub qhov muag ntawm qhov kub ntawm lub pas dej ua ke thiab cov hmoov sib kis hauv lub sijhawm tiag tiag thiab hloov cov laser siv raws li qhov xav tau, qhov kev ua yuam kev interlayer nyob hauv 5 μm.
2. Kev cog qoob loo kho mob: Kev siv tshuaj lom neeg lom neeg ua rau micro- nplai customization.
Cov kev cai nruj ntawm kev kho mob tus kheej yog dab tsi ua rau hlau 3D luam ntawv hauv cheeb tsam kho mob kom meej. Piv txwv li, thaum nws los txog rau orthopedic implants, cov neeg mob cov pob txha yuav txawv heev nyob rau hauv cov duab thiab ceev. Nrog rau cov qauv tsim qauv, kev phais thib ob yog xav tau los ua kom lawv hloov tau ntau dua. Nrog 3D luam ntawv, txawm li cas los xij, nws tuaj yeem ua "ib tus neeg mob, ib txoj cai" raws nraim.
Yuav tsum muaj rau qhov tseeb:
Lub implant's contour yuav tsum muaj qhov tsis raug tsawg dua 0.1 hli thaum piv rau tus neeg mob cov ntaub ntawv CT txhawm rau kom ntseeg tau tias qhov kev ntxhov siab ntawm cov pob txha sib txuas tau sib npaug.
Surface functionalization: Txhawb cov pob txha cell proliferation los ntawm kev siv lub microporous qauv nrog pores uas yog 50 mus rau 500 μm nyob rau hauv loj thiab ib tug porosity sib txawv ntawm ± 2%.
Biocompatibility: Qhov saum npoo roughness yuav tsum tsis pub tshaj Ra1.5 μm los tiv thaiv cov kab mob proliferation thiab cov ntaub so ntswg irritation.
Yuav ua li cas technically:
High- daws teeb meem SLM cov cuab yeej siv 50 μm laser point thiab 15 μm txheej thickness los tsim cov qauv ntawm qib micrometer. Piv txwv li, Teyifei ua titanium alloy hip ob leeg prosthesis rau ib lub tuam txhab orthopedic tshwj xeeb. Nws muaj qhov tseeb bespoke ntawm 0.01mm thiab kev soj ntsuam kev sib raug zoo ntawm 99%.
Tsim rau topology optimization: Siv AI algorithms los ua cov qauv lattice uas siv cov khoom tsawg dua thaum tseem muaj zog. Kev cog hniav cog tau raug txhim kho kom nws 40% sib zog thiab kav ntev peb zaug ua ntej nws yuav tsum tau hloov.
Tom qab- txheej txheem thev naus laus zis: Qhov roughness saum npoo yog txo los ntawm Ra12 μm mus rau Ra0.8 μm los ntawm kev sib xyaw tshuaj polishing thiab laser micro cladding. Cov qauv microporous nyob twj ywm tib yam.
3. Precision pwm: kev ruaj ntseg hauv kev tsim khoom loj mus rau ob peb microns
Hlau 3D luam ntawv yuav tsum tau meej heev nyob rau hauv lub lag luam pwm vim huab hwm coj ntau lawm yuav tsum tau zoo ib yam. Piv txwv li, nrog kev txhaj tshuaj pwm, qhov roughness ntawm cov tub ntxhais qhov saum npoo muaj qhov cuam tshuam ncaj qha rau ntawm cov khoom zoo li, thiab qhov loj ntawm cov kab noj hniav muaj qhov cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom ua ke. Nws yuav siv sij hawm ntau lub lis piam ntawm CNC machining thiab polishing los ua ib lub pwm qub -fashioned txoj kev. Nrog 3D luam ntawv, koj tuaj yeem ua ob qho tib si tib lub sijhawm.
Yuav tsum muaj rau qhov tseeb:
Dimensional stability: Txhawm rau tswj cov cua sov deformation uas tshwm sim thoob plaws kaum tawm txhiab lub voj voog txhaj tshuaj molding, pwm kab noj hniav qhov ntev ntev yuav tsum tau khaws cia hauv ± 0.01mm / 100mm.
Surface smoothness: Yuav kom ua tau raws li qhov xav tau ntawm cov kev xav tau ntawm kev sib txuas lus laser, qhov roughness ntawm optical pwm yuav tsum tsawg dua Ra0.05 μm.
Kev ua kom txias txias: Txhawm rau kom paub tseeb tias pwm kub yog qhov sib txawv, txoj kab uas hla ntawm qhov sib txawv ntawm cov dej txias yuav tsum me dua ± 0.05mm.
Yuav ua li cas nws ua hauj lwm technically:
Adhesive Jet (BJ) thev naus laus zis: Hom kev sib txuas thiab sintering micron - cov hmoov loj ua rau nws tuaj yeem ua pwm nrog qhov raug siab heev. Ib lub tuam txhab ua BJ cov cuab yeej muaj tseeb nyob rau hauv ± 0.05mm thiab muaj qhov roughness ntawm Ra3 μ m. Tom qab sandblasted, nws mus rau Ra1.6 μ m.
Tsib -axis linkage machining: Siv 3D luam ntawv los ntxiv CNC milling rau qhov tseem ceeb mating nto rau qhov tseeb machining. Piv txwv li, Anyuan Pwm tau nce qhov tseeb qhov tseeb ntawm cov khau qauv cores los ntawm ± 0.1mm mus rau ± 0.02mm los ntawm kev siv ua ke ntawm "luam" thiab "milling."
Cov khoom siv tshiab: Tsim pwm hlau hmoov nrog cov thermal conductivity siab, zoo li martensitic aged steel, uas tsuas yog nthuav tawm ib qho - thib peb ntau npaum li lwm cov ntaub ntawv. Qhov no zoo heev txo cov distortion thaum txhaj tshuaj molding.
4. Microfluidic chips: yog txoj hauv kev zoo tshaj plaws los tswj cov kua dej ntawm nanoscale
Microfluidic chips yog qhov tseem ceeb heev hauv thaj chaw xws li kev tshawb nrhiav lom neeg thiab tshuaj lom neeg. Lawv cov hlau yuav tsum tau tswj ntawm ob theem micro thiab nano. Piv txwv li, qee qhov DNA sib txuas nti yuav tsum suav nrog ntau txhiab microchannels hauv thaj tsam 5mm × 5mm, tswj cov channel dav sib txawv ntawm tsawg dua ± 0.5 μm; tsis ua li ntawd yuav ua rau muaj kev hloov pauv dej ntau dhau 5%.
Yuav tsum muaj rau qhov tseeb:
Qhov loj ntawm cov yam ntxwv: Qhov dav ntawm microchannel yuav tsum nyob nruab nrab ntawm 10 thiab 100 μm, thiab qhov tob yuav tsum yog ± 1 μm.
Nto flatness: Yuav ua kom yooj yim rau cov kua ntws, hauv qab ntawm cov channel yuav tsum tsis tshua muaj ntxhib tshaj Ra0.1 μ m.
Kev ntseeg ruaj khov: Txhawm rau kom ntseeg tau tias lub foob tuav nyob rau hauv siab, yuav tsum tsis txhob muaj microcracks lossis pores.
Yuav ua li cas technically:
Ultra- ua laser ceev: siv femtosecond laser pulses kom tshem tawm cov khoom uas tsawg dua li micron tuab thiab zam qhov chaw uas raug tshav kub puas. Ib pab pawg kawm tau siv femtosecond laser los luam nickel-raws li microfluidic chips nrog cov channel dav sib txawv ntawm tsuas yog ± 0.3 μ m.
Electrochemical polishing: Los ntawm kev siv microcurrent tswj thiab electrolyte formulation ua ke, qhov saum npoo roughness mus ntawm Ra5 μ m rau Ra0.05 μ m thaum ua kom cov channel zoo meej.
Multi-cov ntaub ntawv sib xyaw luam ntawv: Hlau-ceramic gradient printing yog siv los muab cov txheej txheem lom neeg tsis zoo rau ntawm phab ntsa sab hauv, uas ua rau cov nti ntev dua.
