I-Metallurgy ibilokhu inesithende sika-Achilles esinzima kakhulu: uma ufuna into ibe nzima kakhulu, kufanele wamukele ukuthi izophuka. Yinkinga engapheli yensimbi eqinisiwe, engamelana nesisindo esimangalisayo kodwa, uma ibhekene nokushaywa okungazelelwe, okungalindelekile, igcina iphukile ibe yizicucu njengengilazi. Kodwa-ke, ithimba lososayensi eGeorgia Tech linqume ukuthi sekwanele futhi bafinyelele esikhonkwaneni besebenzisa Ukuphrinta kwe-3D ngama-laser anamandla amakhulu ukudala into eyayibonakala ingenakwenzeka kuze kube manje.
Le nqubo ihilela ukuxuba izingxenye ezilinganayo ze-aluminium, i-cobalt, i-chromium, insimbi, kanye ne-nickel. Besebenzisa indlela yokukhiqiza eyengeziwe, bakwazile ukuncibilikisa nokupholisa lezi zinto ngokushesha kangangokuthi ama-athomu awabi nesikhathi sokuqina. Umphumela uba yinhlanganisela engeyona nje kuphela ukumelana okuphindwe kathathu Ayigcini nje ngokuba nezinto esivame ukuzisebenzisa ezinkundleni zokwenza izinto zendabuko, kodwa futhi iyakwazi nokuguquguquka okudingekayo ukuze ikwazi ukumunca imiphumela ngaphandle kokuthi ingxenye ihlukane kabili ngesikhathi sokuqala.
Isakhiwo sangaphakathi esimunca ukushaqeka
Imfihlo yalolu shintsho akuyona nje uhlu lwezithako, kodwa nendlela eziphekwa ngayo kuphrinta. Esikhundleni sokusebenzisa izikhunta zendabuko, lapho izinsimbi ziphola khona kancane futhi zidale ukucindezeleka kwangaphakathi, kusetshenziswa [okungacacile - mhlawumbe "inqubo ethile" noma "inqubo"]. uhlelo lombhede wempuphu yensimbiI-laser idlula phezu kwayo, incibilikise impuphu bese iyiqandisa cishe ngokushesha, ungqimba nongqimba. Lokhu kudala uhlobo lwenethiwekhi yangaphakathi, isakhiwo esincane, esibukwa ngaphansi kwe-microscope, sifana ne-athomu-level buffer evimbela ukusabalala kwemifantu.
Ngenxa yalolu hlelo lwama-athomu, izinto zifinyelele ukumelana nokuguqulwa kwe- Ama-gigapascal angu-1,3Into enhle ngalokhu ukuthi, lapho insimbi icindezelwa kakhulu, esikhundleni sokuqhekeka ngokushesha, ama-athomu azihlela kabusha ukuze amelane nokucindezeleka. Lokhu kumelela ushintsho oluphelele embonini, njengoba kuvumela ukukhiqizwa kwezingxenye ezithi Basixwayisa ngokuzikhuhla ngaphambi kokuba baphuke. ngokuphelele, okunikeza isilinganiso esibalulekile sokukwazi ukuqondisa ukuze kugwenywe izingozi ezinkulu kunoma yisiphi isikhungo.
Ukuphepha okukhulu ezinjinini nasezinjinini zomoya
Uma sima sicabange ngokuthi lezi zinhlobo zezinto zokwakha zidingeka kakhulu kuphi, izindiza kanye nomkhakha wamandla kuyahola. Ngaphakathi kwenjini yendiza noma i-turbine kagesi, izingxenye zisebenza ngaphansi kokucindezeleka okuqhubekayo kanye namazinga okushisa aphezulu. Ngalesi sitholo, esesishicilelwe kakade kumagazini odumile i-Nature, onjiniyela bangaklama amajiyometri ayinkimbinkimbi ngaphandle kokushintshwa, ukususa ngokushesha lawo maphuzu abuthakathaka lapho izinkinga zobuchwepheshe zivame ukuqala khona.
Umqondo wokungadingi ukufuna izinsimbi ezintsha nezingavamile emvelweni, kodwa nje hlela kabusha lezo esesizijwayele kakade Ngendlela ehlakaniphile, ivula amathuba amaningi. Ngokukwazi ukuphrinta ingxenye yokugcina ngqo, izinto ziyalondolozwa futhi kufezwa imishini elula kakhulu nesebenza kahle kakhulu. Ekugcineni, kumayelana nokusebenzisa ubuchwepheshe be-laser ukuze ukuphula imingcele yomlando yobunjiniyela okwasibambezele kancane mayelana nokuqina kwezingxenye ezibalulekile.
Sibona igxathu lobuchwepheshe eliguqula ukukhiqizwa kwezithasiselo kube ithuluzi elibalulekile lokuphepha okukhulu kwezimboni. Ngokuhlanganisa lezi zinsimbi ezinhlanu ngokunembile kangaka, kufezwe ingxubevange ehlanganisa ubulukhuni obukhulu... amandla okuguquguquka anokufiselekaInto eyayibhekwa njengenganekwane yesayensi ngaphambilini. Le ndlela ye-laser ivumela ikusasa elinokwethenjelwa kakhulu lokwakhiwa kwengqalasizinda esindayo, okubonisa ukuthi isihluthulelo samandla asigcini nje ngamandla amakhulu, kodwa futhi indlela izingcezu ezihlelwe ngayo ezingeni elincane kakhulu.
