ʻO ka hana ʻana o nā mea hana composite māmā he mau koi kiʻekiʻe ma nā kahua o ka aerospace, automotive, a me ka pale.Ma kēia mau kahua, ʻo ka hōʻemi ʻana i ke kaumaha a me ka hōʻoia ʻana i ka ikaika a me ka lōʻihi nā kumu nui i ka hoʻopau ʻana i ka hana.Eia naʻe, he kaʻina hana manawa a me ka pipiʻi kēia.
ʻO ExOne kahi hui hana hoʻohui hoʻohui i hoʻokumu ʻia ma ʻAmelika Hui Pū ʻIa i loea i ka paʻi 3D no ka metala a me ke one binder jetting.Ua hoʻomohala ʻo ExOne i kahi ʻokoʻa e hiki ai ke hana paʻakikīkalapona kalapona or kīʻaha anianinā ʻāpana i hoʻoikaika ʻia, ma laila e pale aku ai i ka hoʻohana ʻana i nā mea hana kumukūʻai e kūkulu i nā geometries paʻakikī.'O ia ho'i, 'a'ole koi 'ia nā ala kōkua e like me nā mea ho'ohehe'e, nā mea ho'oku'u, a i 'ole nā kui.
ʻO ka ʻenehana kahi kaʻina hana ʻōpala e hoʻohana ana i ka silica paʻi paʻi 3D paʻa a i ʻole ke one ceramic.E like me nā koi ikaika kikoʻī, paʻi 3D wai-soluble spray agent a i ʻole Te ma mua o ka ʻāpana composite e waiho i kahi ʻili me ka ʻole o nā pores, a laila hoʻohui i nā mea hana ma ka ʻili e ka lole a i ʻole superposition.Ma hope o ka ho'ōla ʻana, holoi maʻalahi ka mea kākoʻo hiki ke hoʻoheheʻe ʻia me ka wai paila, e waiho ana i kahi ʻāpana composite puka.A hiki ke hoʻohana hou ʻia ka media i hoʻoheheʻe ʻia no ka paʻi 3D e hiki mai ana.
Ua ʻōlelo ʻo Rick Lucas, Luna Nui ʻenehana o ExOne: "ʻO kēia ka mea a mākou e hana nei no kekahi manawa.ʻO kēia ka mākeke a mākou e makemake ai e ʻimi a hahai.Loaʻa iā mākou nā ʻenekinia i hana i ka ʻoihana composites a hoʻomaopopo i ka poʻe.Aia kahi koi hohonu no ke kūlana quo o ka hana composite.
Mai ka makahiki 2013, ua ʻike nā mea ʻenekinia ExOne no ka manawa mua hiki iā lākou ke hoʻopaʻa i ka silica a i ʻole ka ceramic grit i kahi mea hoʻoheheʻe wai ma 180 ° C.Hoʻopili ʻia nā pilikia i ka pae uhi a me ka hoʻohana ʻana i ka paʻi jet 3D adhesive e hoʻomaikaʻi i ka mea.Ua wehewehe ʻo Lucas: “He porous ka one ceramic a mākou e hoʻohana pinepine ai.No laila, inā ʻoe e hohola wale i ka mea i hui ʻia ma luna o ia mea, e autoclave ia ma lalo o ke kaomi a me ka wela, a laila paʻa;a laila e komo ka resin I loko o ka mea i hui ʻia, ʻaʻole holoi ʻia.No laila, pono mākou e hoʻopili i kahi papa o ka uhi ʻana ma luna o ia mea e pale ai i kēia.I ka makahiki i hala a i ʻole, ua hoʻolilo mākou i ka manawa nui e hoʻomaikaʻi i nā ʻano hana a me nā kaʻina hana, a no ka hōʻoia ʻana e hāʻawi ʻia nā mea kūʻai aku i nā koho uhi maikaʻi.
ʻO nā ʻāpana paipu hope i hana ʻia me nā mea hoʻohui i hana ʻia e ka ʻenehana hiki ke hoʻoheheʻe wai
I kēia lā,Hoʻohana ʻia kēia ʻano hana no ka hana ʻana i ka fiber carbon a me ka fiber glass fiber reinforced composite material, me nā ʻauwaʻa mokulele mokulele, nā pahu kaomi, nā pale, nā pou, a me nā mandrels, ʻoi aku hoʻi no nā hoʻolālā i kūpono ʻole no ka hana ʻana ma o ka ʻenehana kuʻuna.No ka laʻana, ʻo REC, kahi hui e hāʻawi ana i nā ʻauwaʻa ea no nā helikopa kaumaha, ua hoʻohana i ka mea hana flushing ExOne no ka hana ʻana i nā mandrels no nā auwai ea ma nā helikopter CH-35K ʻelua, a ua hāʻawi maikaʻi i kēia mau helikopter i ka US Marine Corps no ka hōʻike.

Ke ho'āʻo nei hoʻi ʻo ExOne e hoʻoponopono i kekahi pilikia maʻamau i loaʻa i nā kaʻina hana autoclaving kuʻuna-ka hoʻonui wela a me kona hopena ma kahi ʻāpana geometry.Ma ke kaʻina hana hoʻoheheʻe, hiki ke hoʻololi i ka pauka e kāohi i ka hoʻonui a hoʻemi i ka deformation.No ka laʻana, kūpono paha ka helu hoʻonui wela kiʻekiʻe o ke one silica no kekahi mau mea, akā i nā hihia ʻē aʻe kahi e koi ʻia ai kahi koena hoʻonui wela haʻahaʻa, ʻoi aku ka maikaʻi o ke one ceramic.
I kēia manawa, hāʻawi nui ʻia kēia ʻenehana ma ke koi ma o ke kikowaena hoʻokipa o ExOne ma United States.Akā ua ʻōlelo ka ʻoihana e manaʻolana e hoʻonui i kēia mau hana i ʻEulopa i ka wā e hiki mai ana, a hiki ke hana pū me nā hoa pili i ka ulu ʻana o ka noi.Ke hana ikaika nei ʻo ExOne e hoʻomaikaʻi hou i ka hopena adhesive ma o ka mana o ka hanauna e hiki mai ana, e hāʻawi i ka ikaika kiʻekiʻe, ʻoi aku ka maikaʻi o ka hoʻonā a me ka hana wela kiʻekiʻe.(Kumu: Zhongguancun Online)

He mea hana mākou i ka fiberglass maka, e like me ka moena ʻeleʻele, ka moena ʻeleʻele, ka moena i ulana ʻia, ka moena ʻokiʻoki, ka moena ʻokiʻoki, ka moena ʻeleʻele.A laila.
