He aha ke kumu o ka paʻi 3D?

3D mīkini paʻi, i ʻike ʻia ʻo ka mīkini paʻi ʻekolu-dimensional (3DP), he ʻano mīkini o ka ʻenehana hana kumulative, ʻo ia hoʻi, ka ʻenehana prototyping wikiwiki. Hoʻokumu ʻia ia ma kahi faila hiʻohiʻona kikohoʻe, me ka hoʻohana ʻana i nā mea wax kūikawā, metala pauka a i ʻole plastic a me nā mea hoʻopili ʻē aʻe e paʻi i nā papa o nā mea hoʻopili e hana i nā mea ʻekolu. I kēia manawa, hoʻohana ʻia nā mea paʻi 3D e hana i nā huahana. ʻO ka ʻenehana o ke kūkulu ʻana i nā mea ma ka paʻi ʻana i ka papa ma ka papa. ʻO ke kumu o ka mīkini paʻi 3D e hoʻokomo i ka ʻikepili a me nā mea maka i loko o ka mīkini paʻi 3D, a e hana ka mīkini i ka papa huahana ma ka papa e like me ka papahana.

ʻO ka ʻokoʻa nui ma waena o ka mīkini paʻi 3D a me ka paʻi kuʻuna ʻo ia ka "ink" e hoʻohana ai ʻo ia nā mea maka maoli. Nui nā ʻano o ka hoʻopaʻa ʻana i nā ʻāpana lahilahi, a ʻokoʻa nā ʻano media i hiki ke hoʻohana ʻia no ka paʻi ʻana, mai nā plastik like ʻole a hiki i nā metala, nā seramika a me nā mea hao. Hiki i kekahi poʻe paʻi ke hoʻohui i nā mea paʻi like ʻole e hana i nā mea i paʻi ʻia ma kahi ʻaoʻao paʻakikī a palupalu ma kekahi ʻaoʻao.

1. Hoʻohana kekahi mau mea paʻi 3D i ke ʻano "inkjet". ʻO ia hoʻi, ua kāpīpī ʻia kahi ʻāpana lahilahi o nā mea plastik wai ma luna o ka pā mold me kahi nozzle paʻi, a laila waiho ʻia kēia uhi ma lalo o ke kukui ultraviolet no ka mālama ʻana. Ma hope o kēlā, hāʻule ka pā poni i kahi mamao loa no ka papa aʻe e hoʻopaʻa ʻia.
