Kev siv 3D luam ntawv tsis ua rau leej twg xav tsis thoob. Koj tuaj yeem luam cov khoom hauv tsev thiab tom haujlwm ntawm ob qho tib si hlau thiab yas. Txhua yam uas tseem tshuav yog txo qhov kev daws teeb meem ntawm lub nozzles thiab nce ntau yam khoom siv. Thiab nyob rau hauv txhua qhov ntawm cov chaw no, ntau, ntau tseem yuav tau ua.
Lwm qhov kev ua tiav hauv kev txhim kho 3D luam ntawv Cov kws tshawb fawb coj los ntawm cov kws tshawb fawb los ntawm ETH Zurich (ETH Zurich). Cov kws tshawb fawb tau nthuav tawm cov thev naus laus zis tshiab rau kev luam ntawv micro-cov khoom nrog cov hlau nrog kev daws teeb meem siab heev - txog 250 nm. Niaj hnub no, 3D luam ntawv ntawm micro-khoom nrog hlau yog nqa tawm siv cov inks tshwj xeeb. Cov no yog cov hlau nanoparticles muab tso rau hauv cov kua hauv daim ntawv ntawm kev ncua (kev ncua). Qhov kev daws teeb meem ntawm cov tshuab luam ntawv no yog micrometers, thiab luam ntawv xaus nrog qhov yuav tsum tau annealing los kho tus qauv. Qhov kawg theem no muaj ntau qhov tsis zoo, suav nrog kev tsim pore tsawg thiab cov organic (solvent) paug. Swiss muab dab tsi?
Cov kws tshawb fawb los ntawm Zurich tau hloov cov hlau ncua kev kawm los ntawm kev luam ntawv ncaj qha nrog hlau. Ntau precisely, hlau ions. Tsim ib lub taub hau luam ntawv nrog ob lub npe hu ua consumable anodes tau raug npaj. Vim li cas ob? Qhov ntawd zoo dua! Koj tuaj yeem luam tawm cov khoom siv hlau hloov pauv nrog ib lossis lwm cov hlau, lossis txawm tias nrog ob qho tib si ib zaug, zoo li tsim cov hlau nrog qhov xav tau ntawm ib qho thiab lwm yam khoom siv. Lub hauv paus ntsiab lus ntawm kev thov 3D luam ntawv yog tias nyob rau hauv high voltage thov mus rau lub anode, hlau ions tawg tawm thiab ya mus rau lub substrate, qhov chaw uas lawv nyob thiab tig mus rau hauv thawj hlau. Rau qhov no ua haujlwm, lub substrate yog coated nrog ib txheej ntawm cov kuab tshuaj nyob rau hauv uas redox tshuaj tiv thaiv tshwm sim. Tab sis kev luam ntawv tshwm sim tam sim ntawd nrog cov hlau ntshiab thiab tsis tas yuav tsum tau annealing tom ntej.
Muaj ntau ntau daim ntawv thov rau xws li technology. Tab sis thawj zaug los rau hauv siab yog microelectronics thiab tsim cov metamaterials nrog cov khoom txawv txawv. Kev luam ntawv nrog qhov tseeb yuav pab tsim cov khoom sib xyaw zoo tshaj plaws thiab txawm tias siv cov ntaub ntawv organic hauv hluav taws xob. Thaum nws los txog rau metamaterials, kev sib xyaw ua ke ntawm cov hlau tuaj yeem ua rau cov khoom siv nrog cov khoom siv zoo nkauj, xws li kev hloov pauv thiab muaj zog.
