Ukuphrinta kwe-3D kuthinta ukusetshenziswa kobuchwepheshe be-quantum

Ukuhlanganiswa kwesakhiwo kungafinyelelwa ngokunyathelisa kwe-3D, ukususa isidingo somklamo ohlangene we-vacuum wokuqala, ukuhlanganisa imisebenzi kanye nokunciphisa usayizi wezingxenye ze-vacuum, ukunciphisa isisindo nokwandisa amandla. Lokhu kuyinzuzo yezingxenye ze-vacuum eziphrintiwe ze-3D zezinhlelo zokusebenza zobuchwepheshe be-quantum

.Ngaphambili, umqondo wokukhiqiza izingxenye ze-vacuum ngokuphrinta kwe-3D kwakunzima ukuwufinyelela ngenxa yezinkinga ze-porosity namandla omshini wezingxenye ezenziwe nge-powder bed metal encibilika ubuchwepheshe bokuphrinta be-3D. Kodwa-ke, intuthuko yakamuva yobuchwepheshe bokuphrinta bensimbi obuyimpushana obuncibilikisa i-3D ithuthuke kakhulu kwikhono lenqubo ukuze kuhlangatshezwane nezidingo zokuminyana kanye nezakhiwo zemishini. Ngenxa yale ntuthuko, ubuchwepheshe bokuphrinta be-3D ngokusebenzisa ukuncibilika kwensimbi kombhede oyimpushana sekuqalile ukubhekana nezingxenye ezibalulekile emikhakheni eminingi. Ukuklama nokukhiqiza kunomthelela omkhulu.

Ngemuva kokukhiqiza le module yokudidiyela edidiyelwe, ososayensi bayisebenzise endaweni yengcindezi ephezulu kakhulu ukudala ikamelo elinomshini elingamelana nengcindezi ethe xaxa, linikeze ukusebenza okudingekayo ukubamba amafu e-athomu abandayo. Ama-athomu apholile futhi agcinwe endaweni ngenhlanganisela ye-laser beam nensimu kazibuthe.

Ukwenza izingxenye ze-vacuum zikhanye ngangokunokwenzeka, ososayensi bathuthukise i-geometry yamachweba abo, banciphisa isikhala phakathi kwabo, futhi bengeza isikhumba sangaphakathi esincanyana ukufaka i-UHV. Ngaphezu kwalokho, ukulingana kokuklanywa kwegumbi kuyagcinwa, kuqinisekiswe ukuthi itheku lihlala libheke ngqo emgodini wendlela ye-laser beam, esiza ukunciphisa ukulahleka kokudluliswa kokukhanya.

Yonke le nqubo ingenye yezicelo ezithakazelisa kakhulu, zokuqala nezingcono kakhulu zohlobo lokukhiqiza okungeziwe kuze kube manje. Njengazo zonke izinhlelo zokushintshanisa ukushisa ezikhiqizwa ukuphrinta kwe-3D, umklamo womhlangano we-vacuum uqukethe isakhiwo se-lattice esikhulisa indawo yangaphandle yevolumu yesilinganiso sekamelo futhi sinomthelela ekushiseni kokushisa. Idizayini yokugcina yegumbi ihambisana nemishini ejwayelekile ye-UHV ye-ultra-high vacuum. 

Ngaphezu kwekamelo, i-Added Scientific ithuthukise ikhoyili kazibuthe eyenza ishaneli epholiswe ngamanzi ukuze ihlole izinzuzo zokukhiqiza okungeziwe.

Umhlangano we-vacuum ukhiqizwa kusetshenziswa i-aluminium alloy AlSi10Mg (i-aluminium alloy esetshenziswa kakhulu ekukhiqizeni okufakwayo) ngenxa yamandla ayo aphezulu aphezulu 3 kanye nobukhulu obuphansi. Ngaphezu kokwelashwa okujwayelekile kokushisa, i-Added Scientific ibuye isebenzise okwehlukile "ukuguga" ukwelashwa kokushisa ukukhulisa amandla wendaba.

Okunye ukucatshangelwa indawo ebucayi yezingxenye ezenziwe yi-PBF powder bed-melting 3D technology technology. Kuzinhlelo ze-UHV, indawo engaphezulu ekholelwa ukuthi yandisa amathuba okuphuma ngokweqile. Kodwa-ke, ngemuva kokuhlolwa okubanzi, iqembu lithole ukuthi ibanga lokushisa elamukelekayo elisebenzayo lifike ku-400 ° C ngisho nangaphandle kokusebenzisa kahle ungqimba lwezinto ezibonakalayo nolokuvikela.

Ngokusetshenziswa kobuchwepheshe be-quantum, izinzuzo zezinto ze-3D eziphrintiwe ziyabonakala. Ikhwalithi yesibonelo se-MOT esenziwe yi-Added Scientific ingama-245 grams - 70% alula kunentengo yensimbi engenasici etholakalayo ethengiswayo.

Lokhu konga ithimba labacwaningi isikhala esiningi esibalulekile selabhu nesinyathelo esibalulekile ekuphatheni kwamadivayisi azayo. Ngokuyinhloko, uma ikamelo lihlanganiswa nohlelo oluklanywe ngokukhethekile futhi lwenziwa ngcono, ikamelo lingenziwa libe lincane.

Ngesifiso sobuchwepheshe be-quantum nokuvuthwa okusheshayo kwezimakethe ezihlobene, ukuthuthukiswa komthamo wezinto zokuhlanza igumbi ezihlanganiswe nezakhiwo zokuphrinta ze-3D kuzosekela kakhulu uhlelo lwe-UK National Quantum Technology Programme yase-UK kanye nokuzibophezela kukahulumeni ekwakheni imboni yezobuchwepheshe i-quantum e-UK .

Ngokuhamba kwesikhathi, ubuchwepheshe be-3D bokuphrinta kungenzeka buqhube inguquko ekwakhiweni kohlelo lwe-vacuum. Ukwethulwa kobuchwepheshe bokukhiqiza obusetshenziswayo ohlelweni lwe-vacuum kusobala ukuthi kuzothinta ukusetshenziswa kobuchwepheshe be-quantum obuphathekayo, futhi kungaphazamisa nomhlaba jikelele wesayensi nowezimboni. Ngasikhathi sinye, lolu hlelo lomshini oluyinkimbinkimbi kakhulu lubonisa ngokusobala izinzuzo zobuchwepheshe bokuphrinta be-3D ekwenziweni kwanoma yiluphi uhlelo oluyinkimbinkimbi.
