Iko kushandiswa kwe3D kudhinda hakuchashamisi chero munhu. Iwe unogona kudhinda zvinhu kumba uye kubasa kubva kune zvese simbi nepurasitiki. Chinosara ndechekudzikisa kugadziriswa kwemanozzles uye kuwedzera zvakasiyana-siyana zvekushandisa. Uye mune imwe neimwe yenzvimbo idzi, zvakawanda, zvakawanda zvichiri kuda kuitwa.
Imwe budiriro mukuvandudza 3D kudhinda masayendisiti anotungamirwa nevaongorori kubva kuETH Zurich (ETH Zurich). Masayendisiti akaunza tekinoroji nyowani inovimbisa yekudhinda zvidiki-zvinhu nesimbi zvine high resolution - kusvika ku250 nm. Nhasi, kudhindwa kwe 3D kwezvinhu zvidiki nesimbi kunoitwa uchishandisa ingi dzakagadzirwa. Aya masimbi nanoparticles akaiswa mumvura nenzira yekumisa (suspension). Kugadziriswa kwemaprinta akadaro ndeye micrometer, uye kudhinda kunopera nekusungirirwa annealing kugadzirisa modhi. Iyi nhanho yekupedzisira ine zvakawanda zvakaipa, kusanganisira yakaderera pore kuumbwa uye organic (solvent) kusvibiswa. Chii chinopihwa neSwitzerland?
Masayendisiti kubva kuZurich akatsiva simbi yakamiswa nekudhinda zvakananga nesimbi. Kunyanya, simbi ions. Dhizaini yemusoro wakadhindwa ine maviri anonzi anodyisa anode yakatsanangurwa. Sei maviri? Zviri nani! Iwe unogona kudhinda simbi diki-chinhu chakasiyana neimwe kana imwe simbi, kana kunyangwe zvese zviri zviviri kamwechete, sekunge kugadzira alloy ine chiyero chinodiwa cheimwe uye zvimwe zvinhu. Nheyo yeinodhindwa ye3D kudhinda ndeyekuti pasi pemhepo yakakwira inoiswa kune anode, maion esimbi anoputika uye anobhururuka achienda kune substrate, kwaanogara uye anoshanduka kuita simbi yekutanga. Kuti izvi zvishande, iyo substrate yakaputirwa neyakagadzika ye solvent umo redox kemikari reactions inoitika. Asi kudhinda kunoitika nekukasira nesimbi yakachena uye hakudi kunotevera annealing.
Kune akawanda maapplication eiyo tekinoroji. Asi yekutanga kuuya mupfungwa ndeye microelectronics uye kusikwa kwemetamaterials ine zvisingawanzoitiki zvinhu. Kudhinda nemazvo akadaro kuchabatsira kugadzira makomisheni akanakisa uye kunyange kushandisa organic zvinhu mumagetsi. Kana zvasvika kune metamaterials, kusanganiswa kwesimbi kunogona kutungamira kune zvinhu zvine zvinonakidza zvemichina zvinhu, sekuve zvese kuchinjika uye kusimba.
