Paʻi 3D, ʻike ʻia hoʻi ʻo ka hana hoʻohui, ʻo ia ke kaʻina hana o ka hana ʻana i nā mea ʻekolu-dimensional mai nā hiʻohiʻona kikohoʻe.ʻAʻole like me nā hana hana subtractive kuʻuna, e pili ana i ka ʻoki ʻana i nā mea mai kahi poloka paʻa, kūkulu ʻia ka paʻi 3D i ka mea hope ma ka hoʻohui ʻana i ka papa ma ka papa.Hiki i kēia ʻano papa-a-papa ke hana i nā ʻano paʻakikī a paʻakikī paha e hiki ke hoʻokō me ka hoʻohana ʻana i nā ʻano kuʻuna.Hiki i ka paʻi 3D ke hoʻohana i nā ʻano mea like ʻole, me nā plastics, metala, ceramics, a me nā mea olaola e like me nā cell ola.Ma ka manawa like, hāʻawi ka paʻi 3D i nā mea maikaʻi e like me ka prototyping wikiwiki, hoʻoponopono, hoʻemi ʻia nā mea waiwai, a me ka hiki ke hana i nā hoʻolālā paʻakikī me ka pololei kiʻekiʻe.Hoʻohana nui ʻia ia i nā ʻoihana he nui e pili ana i ka aerospace, automotive, mālama olakino, kūkulu a me nā huahana mea kūʻai aku no ka prototyping, mea hana a me ka hoʻohana hope ʻana i ka hana ʻāpana.I kēia lā e hoʻolauna kēia ʻatikala i ka paʻi 3D mai kā lākou ʻano a me nā ʻano.
ʻO ka Hoʻohālike Hoʻohālike Hoʻokahi-Fused Deposition
1.FDM
Ke kumu hana:
ʻO ka hoʻohālikelike ʻana i ka fused deposition kekahi o nā ʻano paʻi 3D kaulana loa.Hoʻohana ia ma ke kaomi ʻana i ka filament plastik ma o ka nozzle wela.Hoʻomoe ʻia ka ʻili i hoʻoheheʻe ʻia i lalo i kēlā me kēia papa a hiki i ka pau ʻana o ka ʻāpana.Nui nā ʻano filament 3D i loaʻa - mai nā thermoplastics paʻa a hiki i nā elastomers thermoplastic maʻalahi.
Nā hiʻohiʻona:
Poino:
1. Ua lohi ka paʻi ʻana
2. ʻOi aku ka mānoanoa o ke kiʻekiʻe o ka huahana i paʻi ʻia
ʻO ka lua-Hoʻomaʻamaʻa Māmā
1.SLA
Ke kumu hana:
ʻO Steeolithography ka ʻenehana paʻi 3D mua loa i kūʻai ʻia.Hana ia ma ka hoʻopaʻa ʻana i kahi photopolymer wai i loko o ka ʻāpana hope ma ka ʻimi ʻana i kahi laser mana kiʻekiʻe ma luna o kahi pā kūkulu i ke ʻano o ka ʻāpana kea o ka ʻāpana.Ke hoʻomau nei ke kaʻina hana i ka hui ʻana o kēlā me kēia papa hope i ka papa mua.Hana kēia ʻenehana i nā ʻāpana me nā hiʻohiʻona pololei loa.
Nā hiʻohiʻona:
Poino:
1. He mea hoʻonāukiuki a he ʻawaʻawa iki
2. Uku
3. Ma hope o ka paʻi ʻana, hoʻomaʻemaʻe, wehe i ka bracket, a me UV irradiation no ka hoʻōla lua.
2. LCD
Ke kumu hana:
ʻO ka mīkini paʻi LCD 3D he mea paʻi e hoʻohana ana i ka ʻenehana paʻi resin light-curing.ʻAʻole like me nā mea paʻi 3D kuʻuna e paʻi i ka papa ma ka papa, hoʻohana nā mea paʻi LCD 3D i ke kukui UV e paʻi i nā papa holoʻokoʻa i ka manawa hoʻokahi.ʻO ia hoʻi, ʻoi aku ka wikiwiki a me ka pololei o ka paʻi 3D me kahi paʻi LCD 3D ma mua o nā paʻi 3D ʻē aʻe.
ʻO ka mea i hoʻokaʻawale i nā mea paʻi LCD 3D mai nā ʻano paʻi 3D ʻē aʻe, e like me DLP a i ʻole nā paʻi SLA, ʻo ia ko lākou kumu kukui.Hoʻohana nā mea paʻi LCD 3D i nā ʻāpana UV LCD ma ke ʻano he kumu māmā.No laila, ʻo ke kukui mai ka pā LCD e pā pololei i ka wahi hana ma ke ʻano like.No ka mea ʻaʻole i hoʻonui ʻia kēia kukui, ʻoi aku ka liʻiliʻi o ka distortion pixel no ka paʻi LCD.
Nā hiʻohiʻona:
Poino:
1. He pōkole ke ola o ka pale LCD a pono e pani ʻia ma hope o ka paʻi ʻana no nā kaukani hola.
2. He mea hoʻonāukiuki a ʻona iki ka mea.
ʻEkolu hoʻokahi-Powder Fusion
SLS, SLM
Ke kumu hana:
Hana ʻia ka sintering laser koho ma ke kau ʻana i kahi papa o ka plastik pauka a me ka ʻimi ʻana i ka ʻāpana kea o ka ʻāpana me ka laser.Hoʻoheheʻe ka laser i ka pauka a hoʻohui iā ia.Hoʻomoe ʻia kekahi ʻāpana o ka pauka plastik ma luna o ka papa mua, a hoʻoheheʻe ka laser i ke ʻano ʻāpana keʻa i ka hoʻohui ʻana i ka papa mua.Inā loaʻa nā ala puka no ka pauka i hoʻoheheʻe ʻia, hiki i ke kaʻina hana ke hana i nā ʻāpana kiʻekiʻe i hiki ke paʻi ʻia ma kahi.
Nā hiʻohiʻona:
Poino:
1. He pipiʻi loa ke kumukūʻai
2. Hiki mai ka warping i ka wā e pa'i ana i nā ʻāpana nui
3. He pilau nui ke hana
Hōʻuluʻulu manaʻo
Hoʻopuka kēia ʻatikala i nā ʻenehana paʻi 3D like ʻole a me nā hiʻohiʻona e like me nā ʻano o ka paʻi 3D.No ka ʻike hou aku e pili ana i nā ʻano paʻi 3D a me nā mea hou aʻe e pili ana i ka hoʻomaikaʻi ʻana i kāu huahana paʻi 3D,kāhea iā mā˚ou.
