Dab Tsi Yuav Siv 3D Printing Siv Rau?

Nyob rau hauv xyoo tas los, 3D luam ntawv tau kub, los ntawm thawj zaug tub rog, siab-siab thiab lwm yam kev lag luam loj rau cov kev lag luam tam sim no ntawm 3D luam ntawv. Yog li 3D luam ntawv dab tsi? Nws txawv li cas ntawm luam ntawv zoo tib yam? Txhua tus paub tias kev luam ntawv zoo ib yam yog los tso cov ntaub ntawv uas yuav tsum tau luam tawm ntawm daim ntawv 2D. Cov neeg siv khoom siv siv yog number case, toner thiab lwm yam. Thiab 3D luam ntawv, raws li nws lub npe cuam tshuam, yog 3D luam tawm stereoscopic.

Yuav tsum luam tawm 3D cov khoom, tom qab ntawd peb yuav tsum xub siv lub koos pij tawj 3D qauv software los tsim cov qauv ntawm cov khoom yuav tsum tau, thiab hlais, hloov cov ntaub ntawv hlais rau 3D tshuab luam ntawv, 3D tshuab luam ntawv txheej 3D khoom raws cov ntaub ntawv hlais Sau tawm nws thiab thaum kawg ua qhov khoom tiag. Qhov tau txais txiaj ntsig ntawm 3D tshuab luam ntawv tsuas yog txiav txim siab los ntawm tshuab luam ntawv siv. Dab tsi yog cov neeg siv khoom loj uas peb siv thaum luam ntawv?

Ua ntej, siv cov khoom siv loj uas siv fused deposition cov tshuab tiv thaiv sai sai yog ABS thiab PLA

Cov tau txais kev pom zoo ntawm cov txheej txheem ceev ceev ntawm fused deposition feem ntau yog cov khoom siv thermoplastic, xws li ABS, PLA, thiab lwm yam, uas yog ua los ntawm cov ntawv lim. Cov ntaub ntawv luam tawm yog rhuab hauv lub nozzle kom yaj, thiab cov nozzles yog trajectory nrog tus ntoo khaub lig-txuas ntawm qhov chaw, thiab yuav yaj rau tib lub sijhawm. Cov khoom siv yog extruded thiab kho mob ceev ceev ntawm chav sov. Cov txheej txheem luam ntawv yog pob los ntawm hauv qab mus rau sab saum toj, thiab txheej txheej sab saud ua lub luag haujlwm thiab txhawb nqa txheej txheej tam sim no.

Qhov thib ob, cov neeg siv khoom siv hluav taws xob loj uas siv thaij duab thaij duab yog cov yas cob

Cov tshuab no yog cov tshuab luam ntawv 3D ntxov tshaj plaws thiab yog cov txheej txheem tiv thaiv sai raws li cov qauv photopolymerization ntawm cov kua photosensitive cob. Cov khoom siv sai sai yauv yees duab hluav taws xob hauv qab ultraviolet lub teeb ntawm qee yam nthwv dej thiab siv, thiab hloov los ntawm cov kua hauv lub xeev mus rau lub xeev khov kho. Photocuring yog lub tshuab thev naus laus zis tshaj plaws rau kev luam ntawv 3D. Cov txheej tuab tuaj yeem tswj tau txog li 0.1 hli, yog li qhov ntsuas qhov tseeb ntawm cov khoom moulded yog siab. Cov uas tuaj yeem tuaj yeem kho tshiab nrog high-resolution cov teeb pom kev zoo digital projectors, thiab cov khoom siv cov ntsiab lus, cov ntsiab lus thiab ua tiav ntawm cov thev naus laus zis tshiab tuaj yeem muab piv rau kev txhaj tshuaj txhaj pwm.

Thib peb, cov khoom siv hluav taws xob tseem ceeb uas siv cov xim laser sintering tshuab yog hmoov tshuaj.

Xaiv laser sintering cov txheej txheem yog mus kis cov ntaub ntawv cov hmoov nyob rau sab sauv ntawm qhov tsim ib feem thiab sai flatten nws. Lub zog siab laser tau siv txhawm rau txhawm rau hla ntawm tshooj ntawm ib feem ntawm txheej freshly nteg. Cov khoom siv hmoov yog irradiated los ntawm kev siv cov xim laser ntau. Sintering ua ke kom tau qhov ntoo khaub lig ntawm ib feem thiab ua kom sib haum nrog tus tsim ua ntu hauv qab; tom qab ib ntu yog sintered, txheej tshiab ntawm cov khoom siv hmoov yog thov thiab qhov qis ntu yog xaiv tau sintered.

Tom qab xyoo ntawm txoj kev loj hlob, daim ntawv thov 3D luam tawm tau ua ntau dua thiab nrov npe, thiab tam sim no muaj kev thov ntev ntev hauv cov chaw ntawm cov hniav nyiaj hniav kub, khau, kev tsim kho, tsheb, aviation, thiab kev kho mob. Thaum pib ntawm lub xyoo no, Lub Tsev Kawm Ntawv Qib Siab hauv California, San Diego, thawj zaug siv tshuab 3D luam ntawv sai sai los tsim cov pob txha caj qaum uas ua qauv zoo li tus qauv ntawm lub hauv nruab nrab cov hlab hlwb, uas ua tiav zoo pab cov nas kom rov ua lub cev muaj zog. Kuv ntseeg tias tom qab lub sijhawm ntev, 3D lub tshuab luam ntawv yuav ze rau peb lub neej, thiab tuaj yeem thov rau ntau cov teb.
