Dab tsi yog daim ntawv thov kev cia siab ntawm cov cuab yeej hlau hauv pwm hlau 3D luam ntawv?

Ib, Ib kauj ruam loj rau pem hauv ntej hauv thev naus laus zis: los ntawm "kev ua haujlwm ua haujlwm" mus rau "kev ua tau zoo leap"
1. Muaj peev xwm ua kom cov qauv nyuaj
Ua cov pwm qub -fashioned txoj kev siv txoj kev xws li CNC machining thiab hluav taws xob tawm machining (EDM), uas ua rau nws nyuaj ua rau cov duab nyuaj xws li conformal cooling water channels thiab internal reinforcement ribs. Los ntawm melting hlau hmoov txheej los ntawm txheej, LPBF thev naus laus zis tuaj yeem luam tawm cov txheej txheem nyuaj. Piv txwv li, thaum ua pwm rau hybrid kis tau tus mob vaj tse, Toyota siv Fraunhofer ILT lub gantry loj LPBF cov cuab yeej thiab cov cuab yeej tshiab steel L-40 los ua pwm inserts nrog kauv-zoo li tus pas dej txias. Cov qauv no ua rau pwm qhov kub ntau dua los ntawm 40%, ua rau nws txias sai dua los ntawm 30%, txo qis ntawm cov khoom shrinkage los ntawm 67%, thiab nce tus nqi tawm mus rau 98%.
2. Txhim kho cov ntaub ntawv ua haujlwm zoo li cas
Thaum 3D tshuab luam ntawv hlau, koj yuav tsum tau kho cov teeb meem xws li tawg thiab seem nro. Los ntawm luv luv laser mem tes tshuab, AGH University of Technology nyob rau hauv Poland tau txiav cov tawg ceev ntawm H11 kub ua hauj lwm cuab tam steel nyob rau hauv ib nrab. Lawv kuj tau tswj cov ntsiab lus austenite residual kom lub hardness hloov mus rau ± 5HV. Desktop Hlau kuj tau tsim ib qho Kev Txhaum Dav Hlau (SPJ) thev naus laus zis, uas sai sai ua cov qauv ntawm D2 cov cuab yeej hlau los ntawm kev txau cov hmoov hlau sib tov thiab khi ntawm qhov kub ceev. Nws luam tawm 100 lub sij hawm sai dua li LPBF li niaj zaus, thiab cov khoom siv ntom ntom yog 99.5%, uas ua rau nws hnav ntau dua li qhov tsis tu ncua forged.
3. Kev sib xyaw ua ke ntawm ntau txoj hauv kev los ua khoom
3D tshuab luam ntawv hlau yog feem ntau ua nrog rau lwm yam txheej txheem xws li CNC machining thiab txhaj tshuaj peening los ua ib txheej txheem hu ua "additive subtractive." Yisu Lub Tuam Txhab, piv txwv li, ntiav LPBF los luam cov haujlwm tseem ceeb ntawm cov pwm, suav nrog cov khoom siv cua txias. Cov khoom no yog tom qab CNC precision machined rau qhov roughness ntawm Ra<0.4 μ m, which extends the life of the mold from 200,000 cycles to 500,000 cycles. This mode keeps the design freedom of 3D printing while still meeting the rigorous standards for accuracy and surface quality that molds need.
2, Kev thov hauv kev lag luam: los ntawm "siab-kawg customization" mus rau "scale daim ntawv thov"
1. Kev lag luam tsheb: Lub teeb yuag thiab tsom mus rau kev ua tiav
Tus nqi ntawm kev ua lub tsheb pwm yog 30% mus rau 40% ntawm tag nrho cov nqi ntawm kev tsim lub tsheb, thiab cov txheej txheem tuaj yeem siv li 6 txog 12 lub hlis . 3D luam ntawv ntawm cov cuab yeej hlau tuaj yeem ua rau lub voj voog luv luv. Piv txwv li, B&J Specialty ntiav LPBF thev naus laus zis los ua pwm ntxig rau cov kav dej hauv tsheb. Qhov no txiav lub sij hawm cua txias los ntawm 1 feeb mus rau 40 vib nas this, boosts ntau lawm efficiency los ntawm 30%, thiab ncua lub pwm lub neej los ntawm 25%. Raws li qhov xav tau ntawm lub tsheb tshiab lub zog loj zuj zus tuaj, kev siv cov cuab yeej steel 3D luam ntawv hauv pwm xws li roj teeb pob brackets thiab lub cev muaj zog yuav loj tuaj.
2. Kev kho mob: tshwj xeeb thiab tus kheej xav tau
Cov pwm kho mob yuav tsum tau ua raws li cov qauv xav tau, xws li biocompatible thiab meej heev. Los ntawm topology optimization tsim, cuab yeej steel 3D luam ntawv tuaj yeem ua pwm uas yog ob qho tib si lub teeb thiab muaj txiaj ntsig. Piv txwv li, ib lub tuam txhab kev kho hniav ua rau pom tsis pom kev orthodontic tshuab pwm siv μ-LPBF thev naus laus zis, uas muaj cov ntawv luam tawm ntawm 2-5 μm. Qhov sib xws ntawm orthodontic force tis yog txhim kho los ntawm 40% nrog kev tsim kom txias, thiab tus neeg mob hloov pauv mus los ntawm 85% mus rau 98%. Tsis tas li ntawd, 3D luam ntawv siv cov cuab yeej hlau kuj tseem siv tau los ua cov khoom muaj txiaj ntsig zoo xws li cov lus qhia phais thiab pwm rau kev cog qoob loo.
3. Consumer Electronics: Fast Iteration and making me batches
Cov neeg siv khoom siv hluav taws xob muaj lub neej luv luv, thiab cov pwm hloov tshiab tshwm sim ntau zaus. Nrog cov cuab yeej steel 3D luam ntawv, koj tuaj yeem mus dhau qhov "tsim qauv luam ntawv" txheej txheem. Piv txwv li, qee yam 3C khoom pwm Hoobkas ua rau lub xov tooj txawb pwm pwm nrog LPBF. Qhov no ua rau cov qauv ua pa nrog 0.04mm qhib hauv qhov chaw tso pa, txo qis kev txhaj tshuaj los ntawm 30%, thiab nce pwm lub neej los ntawm 40%. Cov txheej txheem no pab cov lag luam nrawm nrawm rau kev hloov pauv hauv kev ua lag luam thiab txo qis kev phom sij ntawm kev muaj cov khoom lag luam ntau dhau.
3, Cov Khoom Siv Tshiab: Los ntawm "Kev Ua Haujlwm Ib Leeg" mus rau "Multi-Kev Ua Haujlwm Ua Haujlwm"
1. Ua cov cuab yeej tshiab
Cov neeg muag khoom tau ua cov cuab yeej tshwj xeeb steel hmoov vim tias 3D luam ntawv ua haujlwm li cas. Piv txwv li, L-40 cov cuab yeej hlau uas Fraunhofer ILT thiab Toyota ua haujlwm ua ke ua rau muaj kev cuam tshuam zoo ntawm cov tawv tawv (HRC 52-55) thiab zoo toughness los ntawm kev kho cov nqi ntawm cov alloying ntsiab xws li Cr, Mo, thiab V. Cov khoom no tuaj yeem nyob 80% ruaj khov txawm tias qhov kub thiab txias ntawm 600 siab ua haujlwm zoo li pwm.
2. Cov qauv ua los ntawm ntau tshaj ib yam khoom
3D luam ntawv nrog cov cuab yeej hlau hloov los ntawm kev siv ib qho khoom siv rau ntau tshaj ib qho. Piv txwv li, thaum lub tuam txhab luam tawm pwm siv LPBF, lawv muab cov txheej ntawm tooj liab hlau rau saum npoo ntawm pwm kab noj hniav kom nws txias sai heev vim tooj liab muaj thermal conductivity. Cov cuab yeej steel yog siv rau hauv lub cev tseem ceeb kom paub tseeb tias nws muaj zog. Cov qauv sib xyaw no ua rau cov pwm nyob ntev 60% ntev dua thiab tshem tawm qhov xav tau rau kev ua haujlwm ntxiv ntxiv.
3. Siv cov khoom ntse
Tiag - lub sij hawm saib xyuas thiab kev hloov pauv ntawm cov pwm tuaj yeem ua tau thaum sensors siv nrog cov cuab yeej steel 3D luam ntawv. Piv txwv li, ib lub tuam txhab kho mob tau tso cov ntsuas kub hauv LPBF- cov pwm luam tawm thiab siv AI algorithms los hloov cov kev txhaj tshuaj hauv lub sijhawm. Qhov no ua rau cov khoom 50% zoo ib yam. Yav tom ntej, cov cuab yeej steel 3D luam tawm pwm yuav tuaj yeem ua tus kheej- kho thiab kho tus kheej- kho ua tsaug rau cov ntaub ntawv ntse xws li cov duab nco alloys thiab tus kheej- cov ntaub ntawv kho.
