Ukusetshenziswa kokuphrinta kwe-3D akusamangazi muntu. Ungaphrinta izinto ekhaya nasemsebenzini kusuka kokubili insimbi nepulasitiki. Okusele nje ukunciphisa ukuxazululwa kwemibhobho nokwandisa izinhlobonhlobo zezinto zomthombo. Futhi kuzo zonke lezi zindawo, kuningi, kuningi okusamele kwenziwe.
Enye impumelelo ekuthuthukiseni ukuphrinta kwe-3D ososayensi abaholwa abacwaningi abavela kwa-ETH Zurich (ETH Zurich). Ososayensi bethule ubuchwepheshe obusha obuthembisayo bokuphrinta ama-micro-objects ngezinsimbi ezinokulungiswa okuphezulu kakhulu - kufika ku-250 nm. Namuhla, ukuphrinta kwe-3D kwezinto ezincane ezinezinsimbi kwenziwa kusetshenziswa iziyinki ezenziwe ngokukhethekile. Lawa ama-nanoparticles ensimbi afakwe oketshezini ngendlela yokumiswa (ukumiswa). Ukulungiswa kwamaphrinta anjalo kungama-micrometer, futhi ukuphrinta kugcina nge-annealing eyisibopho ukuze kulungiswe imodeli. Lesi sigaba sokugcina sinezimbi eziningi, okuhlanganisa ukwakheka kwezimbotshana eziphansi kanye nokungcola kwe-organic (solvent). Yini enikezwa amaSwitzerland?
Ososayensi baseZurich bashintsha ukumiswa kwensimbi ngokunyathelisa ngokuqondile ngezinsimbi. Ngokunembayo, ion zensimbi. Idizayini yekhanda lokuphrinta elinalokho okubizwa ngokuthi ama-anode asebenzisekayo kuhlongoziwe. Kungani ezimbili? Lokho kungcono! Ungaphrinta i-micro-object yensimbi ngokushintshana ngensimbi eyodwa noma enye, noma ngisho nakho kokubili ngasikhathi sinye, njengokungathi udala ingxubevange enesilinganiso esifiselekayo senye nezinye izinto. Umgomo wokuphrinta kwe-3D okuhlongozwayo ukuthi ngaphansi kwamandla aphezulu ombane asetshenziswa ku-anode, ama-ion ensimbi ayaphuka futhi andizele endaweni engaphansi, lapho ehlala khona futhi aphenduke insimbi yokuqala. Ukuze lokhu kusebenze, i-substrate imbozwe ungqimba lwe-solvent lapho ukusabela kwamakhemikhali e-redox kwenzeka. Kodwa ukuphrinta kwenzeka ngokushesha ngensimbi ehlanzekile futhi akudingi ukukhishwa okulandelayo.
Kunezicelo eziningi zobuchwepheshe obunjalo. Kodwa okokuqala okufika engqondweni yi-microelectronics kanye nokudalwa kwe-metamatadium enezici ezingavamile. Ukuphrinta ngokunemba okunjalo kuzosiza ukudala izinhlanganisela ezinhle kakhulu futhi kusetshenziswe izinto eziphilayo ku-electronics. Uma kukhulunywa nge-metamatadium, inhlanganisela yezinsimbi ingaholela ezintweni ezinezakhiwo ezihehayo zemishini, njengokuvumelana nezimo nokuba namandla.
