Technology Tom qab Automotive Iteration
HP Multi Dav Hlau Fusionyog cov hmoov ua lag luam- txheej txheem txaj uas tsim cov khoom ua haujlwm polymer nrog ze - isotropic mechanical zog. Nws yog qhov tshwj xeeb zoo rau qhov ntim ntau qhov kev pib ua haujlwm tiag tiag xav tau - kaum rau ob peb txhiab daim.
Ib txheej nyias ntawm nylon hmoov (feem ntau PA12) yog kis thoob plaws lub platform tsim. Printheads jet fusing thiab nthuav dav cov neeg sawv cev tsuas yog qhov uas yuav tsum tau ua kom muaj zog. Lub teeb infrared ces yaj cov cheeb tsam ntawd thaum cov hmoov nyob ib puag ncig tseem xoob thiab ua raws li kev txhawb nqa ntuj. Lub platform qis dua, lwm txheej yog siv, thiab lub voj voog txuas ntxiv mus txog thaum lub geometry tiav.
Vim tias cov hmoov txhawb nqa ib feem, sab hauv, lattices, snap-fits thiab undercuts luam tawm yam tsis muaj cov qauv kev txhawb nqa. Tom qab tsim, cov khoom yog txias, unpacked thiab ntxuav; lawv tuaj yeem dyed los yog vapor- smoothed. Cov hmoov tsis siv yog feem ntau rov siv tau ntawm tus nqi nyob ib ncig ntawm 80 feem pua, uas ua rau cov nqi khoom tswj tau.
Cov khoom tiav PA12 feem ntau xa tawm lub zog tensile nyob rau hauv nruab nrab-40s MPa ntau yam, cov khoom zoo ib yam nyob rau hauv txhua qhov kev qhia, kev cuam tshuam zoo thiab tshuaj lom neeg ruaj khov haum rau ntau lub brackets, vaj tse, ducts thiab sab hauv lossis sab nrauv.
Yuav ua li cas MJF piv nrog Txhaj Molding, SLA thiab FDM
Txhaj tshuaj molding tsuas yog ua kev lag luam ib zaug tus nqi pwm kis thoob plaws ntau txhiab qhov chaw zoo ib yam. Cov kev hloov pauv tsim yuav tsum muaj cov cuab yeej tshiab. SLA tsim cov ntsiab lus zoo heev tab sis feem ntau cov resins tsis muaj qhov toughness xav tau rau kev ua haujlwm ntawm lub tsheb. FDM yog siv tau thiab pheej yig, tab sis cov khoom yog anisotropic, qhia txheej kab, thiab xav tau kev tshem tawm.
MJF zam kev siv cuab yeej, xa cov nylon isotropic, tswj cov duab geometry nyuaj yam tsis muaj kev txhawb nqa, thiab tseem raug nqi - siv tau qis - rau - ntim nruab nrab. Qhov kev sib xyaw ua ke no piav qhia tias vim li cas ntau lub tsheb pib thiab me me -batch automakers tam sim no siv nws rau ob qho tib si kev ua haujlwm thiab qhov kawg kawg - siv ntau lawm.
Qhov twg MJF 3D Printing txiav cov nqi tiag tiag rau cov pab pawg tsheb
Dundon Motorsports tau txais ze li $ 65,000 nqe lus rau kev noj haus - khiav pwm. Hloov mus rau HP Jet Fusion PA12 cia lawv luam cov khoom sib tw ua haujlwm nyob rau hauv ib hnub rau ib lub lim tiam es tsis txhob tos lub hlis, ua kom rov ua dua thaum lub tsheb twb nyob ntawm txoj kev, thiab nthuav lawv cov khoom lag luam yam tsis muaj peev txheej ntawm cov cuab yeej siv.
Cov kev lag luam tib yam tshwm sim ntau zaus hauv qis- ntim ua haujlwm:
Tsis muaj pwm peev txhais tau tias tsim kev hloov pauv tsuas yog lub sijhawm engineering xwb.
Qhov kev txiav txim yam tsawg kawg nkaus yog qhov tseem ceeb xoom, sib piv qhov tseeb ntawm qhov qis - ntim cov khoom siv tsheb tsim khoom thiab zam kev pheej hmoo ntawm cov khoom muag.
Iteration ceev txo tus naj npawb ntawm cov neeg tuag kim heev- kawg prototypes-tshwj xeeb tshaj yog muaj txiaj ntsig thaum lub sij hawm prototyping sai rau kev pib tsheb.
Cov khoom tuaj yeem tsim tau raws li qhov xav tau, tshem tawm qhov xav tau rau cov khoom lag luam hauv tsev thaum tsim qauv tseem hloov kho.
Blazin Rods tsim ntau dua 75 qhov ua haujlwmMJF qhov chawrau ib qho kev cai siab - tsheb ua tau zoo. Waylon Jeffrey, 3D Tsim & Engineering Lead ntawm Blazin Rods, tau sau tseg tias kev sib xyaw ntawm CAD thiab HP Multi Jet Fusion ua rau nws muaj peev xwm ua kom tiav cov tsheb ntawm qhov nyuaj thiab qhov tseeb nyob rau hauv ib xyoos. Ntawm qhov loj dua, General Motors, ua haujlwm nrog HP thiab GKN Huab Cua 3D, tsim thiab ua tiav 60,000 kaw cov ntsaws ruaj ruaj rau cov SUV nrov hauv tsib lub lis piam- qhia cov txheej txheem kuj ntsuas thaum ntim ntau ntxiv.
Thaum Lub Zog Yuav Tsum Tau Taw Qhia Tshaj Tawm Nylon
Standard MJF yog txheej txheem polymer optimized rau engineering nylons xws li PA12. Cov ntaub ntawv no suav nrog ntau yam ntawm cov hlua khi, vaj tse, ducts thiab ntau hauv qab -hood lossis sab nrauv qhov chaw nrog lub zog zoo- rau- qhov hnyav piv.
Thaum ib qho khoom siv tiag tiag xav tau hlau- qib kev ua tau zoo- siab- thauj khoom cov khoom sib dhos, qee cov khoom raug tshem tawm lossis cov ntawv thov kev ua si loj heev- laser hmoov- txaj fusion lossis cov txheej txheem hlau zoo sib xws yog siv los hloov. Titanium alloys feem ntau xaiv nyob rau hauv cov rooj plaub rau lawv lub zog - mus rau - hnyav piv thiab corrosion kuj. Ntau qhov kev pabcuam tag nrho- cov chaw tsim khoom lag luam khiav ob qho tib si polymer MJF thiab hlau tshuab, tso cai rau pab pawg los tsim cov txheej txheem tsim nyog rau txhua ntu los ntawm ib tus khub.
Kav -Cov txiaj ntsig hauv pem teb tseem ceeb rau kev pib
Qhov kev paub ntawm Dundon yog ib yam ntawm kev pib thiab me me -series teeb meem: complex geometry, tsis tshua muaj siab ntim, thiab pwm quotes uas yuav siv ntau feem ntawm cov peev nyiaj. MJF tshem tawm cov cuab yeej thaiv thiab compressed kev loj hlob los ntawm peb lub hlis twg mus rau hnub.
Blazin Rods tau siv tib txoj hauv kev thoob plaws ntau qhov chaw ntawm kev tsim kho tag nrho, siv cov khoom sib xws ntawm PA12 thiab kev ceev ntawm cov txheej txheem kom nyob twj ywm ntawm lub sijhawm nruj. Cov kev pab cuam loj xws li GM foob qhov project qhia tau hais tias ib zaug ib qho kev tsim tau siv tau, tib lub thev naus laus zis tuaj yeem txav mus rau hauv siab dua - ntim ntau lawm yam tsis hloov pauv cov haujlwm tseem ceeb.
Thaum MJF Ua Siab Zoo rau Koj Qhov Haujlwm
MJF feem ntau yog qhov kev xaiv zoo tshaj plaws thaum koj xav tau cov khoom siv nylon lossis cov qauv uas yuav tsum muaj sia nyob ntawm kev sim tsheb tiag tiag, ntim hauv qhov qis - mus rau - nruab nrab, cov qauv tsim tseem hloov pauv tsis tu ncua, geometry nyuaj lossis qhov hnyav txo yog qhov tseem ceeb, thiab zam cov nqi pwm ntxiv rau cov khoom muag ntau yog qhov tseem ceeb.
Nws dhau los ua qhov tsis txaus nyiam thaum cov khoom ntim ruaj khov ua rau cov cuab yeej amortized kom meej meej pheej yig dua, qhov xav tau cov hlau lossis qhov kub thiab txias sab nraum lub peev xwm PA12 tam sim no, lossis cov kev xav tau zoo nkauj thiab qhov ntev tshaj li qhov kev tshaj tawm -processed MJF tuaj yeem xa (vapor smoothing thiab dyeing kaw qhov sib txawv rau ntau daim ntawv thov).

FAQ
Q: Peb tab tom saib ntawm 50–200 brackets lossis duct qhov chaw-MJF tus nqi li cas los tiv thaiv kev txiav pwm?
A: Ntawm qhov ntau ntawm MJF txoj kev yuav luag ib txwm qis dua vim tias tsis muaj cuab yeej siv. Thaum cov ntim tau txav mus rau hauv ob peb - txhiab ntau thiab cov qauv tsim tau khov, kev txhaj tshuaj molding tuaj yeem ua tau zoo dua. Feem ntau cov chaw muab kev pabcuam yuav hais ob qho kev xaiv ib sab rau tib lub geometry.
Q: PA12 MJF qhov chaw puas tuaj yeem nyob ntawm lub tsheb raws li cov hlua khi, vaj tse lossis cov khoom siv sab hauv?
A: Feem ntau ntawm cov luag haujlwm, yog. Cov khoom muaj lub zog tensile, ze rau - tus cwj pwm isotropic, muaj kev cuam tshuam zoo thiab ua haujlwm rau cov dej noo thiab ntau cov kua hauv tsheb. Cov pab pawg tseem siv tau los tiv thaiv lawv cov kev thauj khoom tshwj xeeb, qhov kub thiab txias thiab kev vibration profiles, tab sis ntau qhov qauv thiab cov khoom tsim tau ua tiav hauv cov ntawv thov no-tshwj xeeb tshaj yog nyob rau hauv prototyping ceev ceev rau lub tsheb pib thiab qis- ntim cov khoom siv tsheb.
Q: Ob peb ntawm peb cov khoom yuav tsum muaj zog dua - tib lub khw puas tuaj yeem luam titanium?
A: Polymer MJF tshuab luam ntawv nylons. Titanium thiab lwm yam hlau yog tsim los ntawm cov hlau additives. Ntau lub tuam txhab ua haujlwm ob qho tib si thev naus laus zis, yog li cov khoom siv polymer thiab hlau tuaj yeem muab los ua ke.
Q: Nws feem ntau siv sijhawm ntev npaum li cas kom tau txais thawj txheej ntawm automotive prototypes?
A: Txheem PA12 qhov chaw nrog kev ua tiav feem ntau xa tuaj hauv ob peb hnub mus txog ib lub lis piam tom qab cov ntaub ntawv pom zoo. Cov khoom loj dua los yog kev ua tiav tiav ntxiv me ntsis sij hawm.
