ʻO ka hoʻohana ʻana i ka ʻenehana paʻi 3D ma ke kahua o ka hana kaʻa

I loko o kēia mau makahiki, ʻo ke ala kūlohelohe loa no ka paʻi 3D e komo i ka ʻoihana kaʻaprototyping wikiwiki. Mai nā ʻāpana o loko o ke kaʻa a hiki i nā kaʻa, nā pahu i mua, nā poloka ʻenekini, nā poʻo cylinder, a me nā ʻauwaʻa ea, hiki i ka ʻenehana paʻi 3D ke hana i nā prototypes kokoke i nā ʻāpana kaʻa. No nā hui kaʻa, ʻo ka hoʻohana ʻana i ka paʻi 3D no ka prototyping wikiwiki ʻaʻole ia he mea maʻalahi, akā e mālama pono ia i ka manawa. Eia naʻe, no ka hoʻomohala hoʻohālike, ʻo ka manawa ke kālā. Ma ke ao holoʻokoʻa, ke hoʻohana nei ʻo GM, Volkswagen, Bentley, BMW a me nā hui kaʻa kaulana ʻē aʻe i ka ʻenehana paʻi 3D.

ʻElua ʻano hoʻohana no nā prototype paʻi 3D. Aia kekahi ma ke kahua hoʻohālike kaʻa. ʻAʻole loaʻa i kēia mau prototype nā koi kiʻekiʻe no nā waiwai mechanical. E hōʻoia wale lākou i ka hiʻohiʻona hoʻolālā, akā hāʻawi lākou i nā mea hoʻolālā hoʻohālike automotive me nā mea ʻekolu-dimensional. Hoʻokumu nā kumu hoʻohālike i nā kūlana kūpono no nā mea hoʻolālā e hoʻolālā i nā mea hou. Hiki ke hoʻomaʻamaʻa ʻia nā mea resin transparent kūikawā i hoʻohālikelike ʻia me nā mea hana ma hope o ka paʻi ʻana e hōʻike i kahi hopena kukui mālamalama maoli.

ʻO ka mea ʻē aʻe he prototypes hana a kiʻekiʻe paha, kahi e loaʻa ai ke kūpaʻa wela maikaʻi, kūpaʻa corrosion, a i ʻole hiki ke kū i ke koʻikoʻi mechanical. Hiki i nā mea hana kaʻa ke hoʻohana i nā prototypes o ia mau ʻāpana paʻi 3D no ka hoʻāʻo hana. ʻO nā ʻenehana paʻi 3D a me nā mea i loaʻa no ia mau noi, ʻo ia hoʻi: ʻenehana-kiʻekiʻe fused deposition modeling 3D mīkini paʻi a me nā filaments plastic engineering a i ʻole fiber reinforced composite material, koho laser fusion 3D mea paʻi a me ka ʻenekinia plastic powder, fiber reinforced composite powder material. Ua hoʻokomo pū kekahi mau ʻoihana paʻi 3D i nā mea resin photosensitive kūpono no ka hana ʻana i nā prototypes hana. Loaʻa iā lākou ke kūpaʻa hopena, ka ikaika kiʻekiʻe, ka pale wela kiʻekiʻe a i ʻole ka elasticity kiʻekiʻe. Ua kūpono kēia mau mea no ka hoʻomaʻamaʻa ʻana i nā kukui stereo 3D mea paʻi.

Ma keʻano laulā, komo nā prototypes paʻi 3D i kaʻoihana kaʻaʻano hohonu. Wahi a kahi noiʻi piha i hōʻike ʻia e Market Research Future (MRFR), ʻo ke kumukūʻai mākeke o ka paʻi 3D i ka ʻoihana automotive e hiki i 31.66 biliona yuan e 2027. ʻO ka nui o ka ulu ʻana o ka makahiki mai 2021 a 2027 he 28.72%. I ka wā e hiki mai ana, ʻoi aku ka nui o ka mākeke o ka paʻi 3D i ka ʻoihana kaʻa.
