ʻAʻole kahaha ka hoʻohana ʻana i ka paʻi 3D i kekahi. Hiki iā ʻoe ke paʻi i nā mea ma ka home a ma ka hana mai ka metala a me ka plastic. ʻO nā mea a pau i koe e hōʻemi i ka hoʻonā o nā nozzles a hoʻonui i nā ʻano kumu kumu. A ma kēlā me kēia o kēia mau wahi, nui nā mea i koe e hana ʻia.
ʻO kekahi hoʻokō i ka hoʻomaikaʻi ʻana i ka paʻi 3D nā ʻepekema i alakaʻi ʻia e nā mea noiʻi mai ka ETH Zurich (ETH Zurich). Ua hōʻike ka poʻe ʻepekema i kahi ʻenehana hoʻohiki hou no ka paʻi ʻana i nā micro-objects me nā metala me ka hopena kiʻekiʻe loa - a hiki i 250 nm. I kēia lā, hoʻokō ʻia ka paʻi 3D o nā micro-objects me nā metala me ka hoʻohana ʻana i nā inika i hana ʻia. ʻO kēia nā nanoparticles metala i hoʻokomo ʻia i loko o kahi wai ma ke ʻano o ka hoʻokuʻu ʻana (suspension). ʻO ka hoʻonā ʻana o ia mau mea paʻi he micrometers, a pau ka paʻi ʻana me ka hoʻopili pono ʻana e hoʻoponopono i ke kumu hoʻohālike. He nui nā hemahema o kēia pae hope loa, e like me ka hoʻokumu ʻana o ka pore haʻahaʻa a me ka hoʻohaumia ʻana (solvent). He aha kā Swiss e hāʻawi ai?
Ua pani ka poʻe ʻepekema mai Zurich i ka hoʻokuʻu ʻia me ka paʻi pololei ʻana me nā metala. ʻOi aku ka pololei, nā ion metala. Ua manaʻo ʻia kahi hoʻolālā o kahi poʻo paʻi me ʻelua i kapa ʻia nā anodes consumable. No ke aha ʻelua? ʻOi aku ka maikaʻi! Hiki iā ʻoe ke paʻi i kahi micro-object metala me kekahi metala ʻē aʻe, a i ʻole me nā mea ʻelua i ka manawa hoʻokahi, me he mea lā e hana ana i kahi huila me ka ratio makemake o kekahi a me nā mea ʻē aʻe. ʻO ke kumumanaʻo o ka paʻi 3D i manaʻo ʻia ʻo ia ma lalo o ka volta kiʻekiʻe i hoʻopili ʻia i ka anode, haki nā ion metala a lele i ka substrate, kahi e noho ai a huli i ka metala kumu. No ka hana ʻana, ua uhi ʻia ka substrate me kahi papa o ka solvent kahi e loaʻa ai nā hopena kemika redox. Akā, hiki koke ke pa'i 'ana me ka metala ma'ema'e a 'a'ole koi 'ia ka annealing ma hope.
Nui nā noi no ia ʻenehana. Akā ʻo ka mea mua e hiki mai i ka noʻonoʻo ʻo nā microelectronics a me ka hana ʻana i nā metamaterials me nā waiwai maʻamau. ʻO ka paʻi ʻana me ia pololei e kōkua i ka hana ʻana i nā pūhui maikaʻi loa a me ka hoʻohana ʻana i nā mea kūlohelohe i ka uila. I ka hiki ʻana i nā metamaterials, hiki i ka hui ʻana o nā metala ke alakaʻi i nā mea me nā waiwai mechanical hoihoi, e like me ka maʻalahi a me ka ikaika.
