Paʻi 3D Kaʻa Leʻaleʻa

Hoʻomaka no ka paʻi 3D:

He aha ka paʻi 3D?
ʻO ka paʻi 3D kahi ʻenehana hoʻohui i hoʻohana ʻia e hana i nā ʻāpana.He 'additive' ia no ka mea, ʻaʻole ia e koi i kahi poloka o nā mea a i ʻole kahi ʻōpala e hana ai i nā mea kino, hoʻopaʻa wale ia a hoʻohui i nā papa o nā mea.ʻO ka maʻamau wikiwiki, me nā kumukūʻai hoʻonohonoho haʻahaʻa haʻahaʻa, a hiki ke hana i nā geometries paʻakikī ma mua o nā ʻenehana 'kuʻuna', me kahi papa inoa o nā mea waiwai.Hoʻohana nui ʻia ia i ka ʻoihana ʻenekinia, no ka prototyping a me ka hana ʻana i nā geometries māmā.

Paʻi 3D a me ka prototyping wikiwiki
ʻO 'Rapid prototyping' kekahi huaʻōlelo i hoʻohana ʻia i kekahi manawa e kuhikuhi i nā ʻenehana paʻi 3D.Hoʻomaka kēia i ka mōʻaukala mua o ka paʻi 3D i ka wā i puka mua ai ka ʻenehana.I ka makahiki 1980, i ka wā i hana mua ʻia ai nā ʻenehana paʻi 3D, ua kapa ʻia lākou he ʻenehana prototyping wikiwiki no ka mea i kēlā manawa ua kūpono ka ʻenehana no nā prototypes, ʻaʻole nā ​​ʻāpana hana.

I kēia mau makahiki i hala iho nei, ua oʻo ka paʻi 3D i mea hoʻonā maikaʻi loa no nā ʻāpana hana he nui, a ua lilo nā ʻenehana hana ʻē aʻe (e like me CNC machining) i mea maʻalahi a maʻalahi no ka prototyping.No laila, ʻoiai e hoʻohana mau ana kekahi poʻe i ka 'prototyping wikiwiki' e kuhikuhi i ka paʻi 3D, ke ulu nei ka huaʻōlelo e kuhikuhi i nā ʻano o ka prototyping wikiwiki loa.

ʻO nā ʻano like ʻole o ka paʻi 3D
Hiki ke hoʻokaʻawale ʻia nā mea paʻi 3D i kekahi o nā ʻano hana:

Vat Polymerization: hoʻōla ʻia ka photopolymer wai e ka mālamalama
Mea hoʻoheheʻe ʻia: hoʻoheheʻe ʻia ka thermoplastic ma o ka nozzle wela
Pauda Bed Fusion: Hoʻohui ʻia nā ʻāpana pauka e kahi kumu ikaika kiʻekiʻe
Material Jetting: waiho ʻia nā kulu o ka wai photosensitive fusing agent ma kahi moena pauka a hoʻōla ʻia e ka mālamalama
Binder Jetting: waiho ʻia nā kulu o ka mea hoʻopaʻa paʻa wai ma luna o kahi moena o nā mea granulated, i hui pū ʻia ma hope.
ʻO ka hoʻoheheʻe ʻana i ka ikehu pololei: hoʻoheheʻe ʻia i ka manawa like a hoʻopaʻa ʻia
Lamination Pepa: ʻokiʻoki ʻia nā ʻāpana o nā mea i hoʻohālikelike ʻia a hoʻopaʻa pū ʻia
