Ibhere lase-Antarctic liphinde labika ngokuphindaphindiwe ngobuchwepheshe bokuphrinta be-3D obunezithombe ezimbili, okuwubuchwepheshe bokuphrinta be-3D esikalini se-nanometer, obusebenzisa i-photolithography enezithombe ezimbili ukuphrinta izakhiwo zesikali se-nano. Kodwa-ke, i-drawback yayo enkulu ukuthi Ijubane lokuphrinta lihamba kancane kakhulu. Ngakho-ke, ingabe ikhona indlela yokwandisa isivinini sayo sokuphrinta?

I-Hong Kong Wen Wei Po News: Ubuchwepheshe bokuphrinta be-3D buye baziwa kancane kancane ngemva kweminyaka engaphezu kwengu-20 yokuthuthuka. Abantu bangakwazi ukukhiqiza ngokushesha imikhiqizo eqediwe ngokwakha amamodeli edijithali. Ubuchwepheshe bokuphrinta be-Nano-level 3D bungokwegatsha lokuphrinta kwe-3D, futhi imikhiqizo ephrintiwe ngokuvamile mincane ngokwanele ukuthi ingabonwa ngeso lenyama. Cha, kodwa inkimbinkimbi ayikho ngaphansi kwalokho kwemikhiqizo yokuphrinta ye-3D yendabuko, futhi ukunemba kuphinde kube kumakhulu ama-nanometers. Kodwa-ke, ubuchwepheshe bokuphrinta be-3D obukhona be-nano-level sekuyisikhathi eside bubhekene nobunzima obubili bejubane eliphansi lokuphrinta kanye nezindleko eziphezulu, futhi ayikakwazanga ukufeza izinhlelo zokusebenza ezibanzi. .Muva nje, u-Chen Shiqi, uprofesa ohlanganyele woMnyango Wezobunjiniyela Bemishini Nezishintshayo, Isikole Sobunjiniyela, Inyuvesi Yase-China yase-Hong Kong, kanye nethimba lakhe bagqashule emgodleni wezemfundo futhi bathuthukisa ``i-femtosecond projection two-photon lithography 3D printing' ' (FP-TPL) ubuchwepheshe, obukhulise kakhulu isivinini sokuqala sokuphrinta. Nyusa ngezinkulungwane izikhathi ezingu-10,000, futhi wonge izindleko ngokucasha, ngokuncipha ngo-98%.

Ubuchwepheshe obujwayelekile bokuphrinta bokunemba okuphezulu kwe-3D ngokuvamile busebenzisa isistimu ye-polymerization yezithombe ezimbili (TPP), esebenzisa intambo ye-laser ukuze ibhale iphoyinti ngephoyinti, bese iphrinta isendlalelo ngesendlalelo. 0.1mm3 ngehora), ngisho noma kuthatha izinsuku ezimbalwa noma ngisho amasonto ukwenza amadivaysi amancane. Ngaphezu kwalokho, umthombo wokukhanya we-laser unomkhawulo wokuphila. Ngokuvamile, umshini ngamunye ungasetshenziswa kuphela amahora angaba ngu-20,000. Ukusetshenziswa isikhathi eside kubangele izindleko eziphezulu zokuphrinta kwe-TPP. .

Iqhinga elidala unyaka owodwa, iqhinga elisha amahora angu-10

Ukuze banqobe ubunzima bobuchwepheshe obukhona, u-Chen Shiqi nethimba lakhe bazinikele ocwaningweni iminyaka engu-5, futhi babambisana ne-US Lawrence Livermore National Laboratory ukuthuthukisa ubuchwepheshe be-FP-TPL. Imiphumela yocwaningo efanele ishicilelwe ngo-Okthoba kulo nyaka. Ishicilelwe kujenali yezemfundo iSayensi. Ubuchwepheshe obusha busebenzisa indlela entsha yokugxilisa ingqondo ukukhiqiza amaphuzu okukhanya ayizigidi ezingu-1 ngesikhathi esifanayo ukwakha indiza elula, ukuguqula inqubo yokunyathelisa ye-laser 3D ibe indiza yonke ebhalayo, futhi isivinini sokunyathelisa sikhuphuka kakhulu ngezinkulungwane zezikhathi ukuya ku-1 Ten. izikhathi eziyinkulungwane. Esikhathini esidlule ubuchwepheshe obusetshenziselwa ukuskena isikhathi esincane, ubuchwepheshe obusha bungaskena indiza yonke futhi buqedele ungqimba lokubhala ngama-femtosecond.

Ubuchwepheshe be-FP-TPL bakhuphula isivinini sokunyathelisa sibe ngu-10 kuya ku-100mm3 ngehora [Inothi lebhere lase-Antarctic: elilingana nokwenyuka izikhathi ezingu-100-1000], ngakho-ke izindleko zokunyathelisa zehliswa kakhulu zibe amadola angu-1.5 US dollar i-cubic millimeter ngayinye, futhi ukunemba futhi ithuthukisiwe, ifinyelela ku-140 × 175 nm.

U-Chen Shiqi wachaza ukuthi ubuchwepheshe bokunyathelisa bezinga le-nano ngokuvamile abusetshenziselwa ukuphrinta izinto ezinkulu ngenxa yezidingo zabo zokunemba okuphezulu. Wenze isibonelo. Isibonelo, kungase kuthathe cishe unyaka ukuphrinta idola lase-Hong Kong elingu-1 usebenzisa indlela evamile ye-TPP, kodwa uma usebenzisa ubuchwepheshe be-FP- TPL bungafushaniswa bube ngaphansi kwamahora angu-10.

Kusenebanga ukusuka ekukhiqizeni kwezimboni

Mayelana nokusetshenziswa kwesikhathi esizayo kobuchwepheshe be-FP-TPL, u-Chen Shiqi uthe ngenxa yezindleko zezindleko, i-FP-TPL isekude nokukhiqizwa kwezimboni ezinkulu, kodwa izinkampani zezezimali zaseSilicon Valley sezivele zixhumana neqembu. Emkhakheni wokuphrinta kwe-3D encane, sinethemba lokusebenzisa i-FP-TPL ocwaningweni lokuhlola emikhakheni efana ne-Optics ne-biomedicine, kanye nokukhiqiza okokusebenza kokuhlola okuhlanganisa amakristalu e-photonic, ama-nanorobots, ama-scaffolds e-biological noma ama-metamatadium.

U-Chen Shiqi uthweswe iziqu eMnyangweni Wezobunjiniyela Bemishini eNyuvesi yaseTsinghua e-Taiwan, wathola iziqu ze-master kanye neziqu zobudokotela e-Massachusetts Institute of Technology nase-Cambridge University, ngokulandelana, futhi wenza ucwaningo e-Harvard Medical School. Ujoyine i-CUHK ngo-2011 futhi ucwaningo lwakhe oluyinhloko luhlanganisa Ukuphrinta kwe-nano 3D, izithombe ze-3D ezinesivinini esikhulu, njll. Ngonyaka odlule, wawina i-US R&D Global Top 100 Technology R&D Award ngemiphumela yakhe yocwaningo ku-``Digital Holographic Nano 3D Printer. ''.

``I-Digital Holographic Nano-Builder'' (I-Nano-Builder) eyakhiwe nguSolwazi Chen Shiqi ovela eMnyangweni Wezobunjiniyela Bemishini Nezishintshayo, Isikole Sobunjiniyela, i-Chinese University of Hong Kong (CUHK), kanye nethimba lakhe liwine umhlaba wonke. I-R&D100 eyaziwa ngele-``Oscar in Innovation and Technology'' Iqashelwa umklomelo waminyaka yonke, yakhethwa njengenye yezinto eziqanjwe kabusha eziyi-100 emhlabeni ngo-2018. I-Nano-Builder ingaphrinta izingxenye ezinhle eziyinkimbinkimbi nezinjengezinwele ngemizuzwana. , elungele ikakhulukazi i-nanotechnology ephezulu, izinto ezithuthukisiwe, ama-micro-stents kanye nezidakamizwa Ucwaningo lobuchwepheshe bokudlulisa kanye nezidingo zentuthuko.

I-Nano-Builder isebenzisa ukuskena kwe-digital holographic laser scanning kanye nobuchwepheshe bokubumba i-beam, obukwazi ukuskena okugxilwe kakhulu kwesivinini esikhulu (22.7 kHz), ukwephula imikhawulo yamaphrinta endabuko e-3D ngokugxila okukodwa nokunemba okuphansi, futhi ngesikhathi esifanayo ukuzuza i-nano- ukunemba kwezinga lokuphrinta. Ubuchwepheshe bungaskena ngokungahleliwe endaweni enezinhlangothi ezintathu, ngaphandle kokuskena kusukela phansi kuye phezulu kusendlalelo ngokwesendlalelo, esidlulela ngale kwendololwane yesikhala.

Amaphoyinti amaningi wokuskena angahanjiswa aye kunoma iyiphi indawo endaweni yokuphrinta ngesivinini esifanayo. Ngisho nangaphandle kokusekelwa kwesakhiwo nezinto zokwakha, isengakwazi ukuphrinta izakhiwo ezilele phezulu eziyinkimbinkimbi, imikhiqizo enembile nenemininingwane emincane eqediwe. Uma kuqhathaniswa nobuchwepheshe obukhona, inqubo ayidingi Imosha izinto ezengeziwe njengokusekela; futhi isikhathi esiphelele sokunyathelisa silingana nomthamo oqinile wesakhiwo, futhi akuhlangene nobunzima, okuthuthukisa kakhulu isivinini nokunemba kokunyathelisa. USolwazi Chen Shiqi uthe i-Nano-Builder esheshayo nenembile iyona ephumelela kakhulu Isiza ekwakhiweni kwemishini ehlukahlukene yocwaningo lwesayensi yezinga elincane (njengamakristalu e-photonic, amadivaysi e-micro-nano fluidic, izicubu ezilingisayo zebhayoloji nezikafula, ukulethwa kwezidakamizwa. amathuluzi, njll.) ukusiza abacwaningi ekwenzeni izingxenye eziyinkimbinkimbi neziyinkimbinkimbi, ngaleyo ndlela baguqule i-nanotechnology nezinto ezithuthukisiwe Kanye nobuchwepheshe obuhlobene bamathuluzi ezokwelapha.

Esinye isici esiyinhloko ukuklama kwayo kwe-modular yesistimu elula nokunwebeka. Imojula ye-imaging ye-Nano-Builder ingashintshwa ngokushesha, inikeze imisebenzi ethuthukisiwe ye-imaging microscopy enezithombe ezimbili, ezisetshenziswa ekucabangeni kwebhayoloji nezokwelapha kanye neminye imikhakha. Kuzicelo zocwaningo lwezakhi zofuzo, i-Nano-Builder ingashukumisa ngokunembile ama-neurons amaningi ebuchosheni bebhayoloji ngesikhathi esifanayo ngaphandle kokulimaza izakhiwo ezizungezile zama-neurons. Ingasetshenziselwa ucwaningo lwesikhathi eside kumasekhethi emizwa yobuchopho nemisebenzi ethile, efana nomuzwa wokuhogela kumagundane noma i-zebrafish. , Imisebenzi ebonakalayo noma yengqondo, enweba izinzuzo zokuskena okungahleliwe kwe-3D kumathuluzi ezokwelapha noma ayisisekelo ocwaningo lwebhayoloji.
