Hoʻohana mākou i nā kuki e hoʻonui i kou ʻike.Ma ka hoʻomau ʻana i ka nānā ʻana i kēia pūnaewele, ʻae ʻoe i kā mākou hoʻohana ʻana i nā kuki.ʻIke hou aku.
He ʻatikala mai ka Polymer Testing magazine e aʻo ana a hoʻohālikelike i ka maikaʻi o kekahi mau mea hana polymer composite i hana ʻia me ka hoʻohana ʻana i ka ʻenehana paʻi 3D, e like me ka morphology a me ke ʻano o ka ʻili, nā waiwai mechanical, a me nā waiwai wela.

Pono nā ʻāpana polymer i hana ʻia i nā ʻano like ʻole e like me ko lākou kumu, hiki ke hāʻawi ʻia kekahi o ia mau mea me ka hoʻohana ʻana i nā filament polymer i haku ʻia me nā ʻano mea like ʻole.
ʻO kahi lālā o ka hana hoʻohui (AM), i kapa ʻia ʻo ka paʻi 3D, kahi ʻenehana ʻokiʻoki e hoʻohui i nā mea e hana ai i nā huahana e pili ana i ka ʻikepili kumu hoʻohālike 3D.
No laila, liʻiliʻi ka ʻōpala i hana ʻia e kēia kaʻina hana.Hoʻohana ʻia ka ʻenehana paʻi 3D i nā noi like ʻole, me ka hana nui o nā mea like ʻole, a e hoʻonui wale ʻia ka nui o ka hoʻohana.
Hiki ke hoʻohana ʻia kēia ʻenehana no ka hana ʻana i nā mea me nā hale paʻakikī, nā mea māmā, a me nā hoʻolālā maʻamau.Eia kekahi, loaʻa i ka paʻi 3D nā mea maikaʻi o ka pono, hoʻomau, versatility a me ka hōʻemi ʻana i ka pilikia.
ʻO kekahi o nā mea koʻikoʻi o kēia ʻenehana e pili ana i ke koho ʻana i nā ʻāpana kūpono no ka mea he mana nui lākou i ka huahana, e like me kona ʻano, ka nui, ka nui o ka hoʻomaha ʻana, a me ka gradient thermal.Hoʻopili kēia mau ʻano i ka ulu ʻana o ka microstructure, kona mau ʻano a me nā hemahema.
Hiki ke hoʻohana ʻia ke aʻo ʻana i ka mīkini e hoʻokumu i ka pilina ma waena o nā kūlana kaʻina, microstructure, ʻano ʻāpana, haku mele, nā hemahema, a me ka maikaʻi mechanical o kahi huahana paʻi kikoʻī.Hiki i kēia mau hoʻohui ke kōkua i ka hōʻemi ʻana i ka nui o nā hoʻāʻo e pono ai e hana i nā huahana kiʻekiʻe.
ʻO ka polyethylene kiʻekiʻe (HDPE) a me ka polylactic acid (PLA) nā polymers ʻelua i hoʻohana pinepine ʻia ma AM.Hoʻohana ʻia ʻo PLA ma ke ʻano he kumu nui no nā noi he nui no ka mea hiki ke hoʻomau, hoʻokele waiwai, biodegradable a loaʻa nā waiwai maikaʻi loa.
ʻO ka hana hou ʻana i ka plastik kahi pilikia nui e kū nei i ka honua;no laila, he mea maikaʻi loa ke hoʻokomo ʻana i ka plastic recyclable i loko o ke kaʻina hana paʻi 3D.
Ke hānai mau ʻia nei ka mea paʻi i loko o ka wai wai, mālama ʻia ka mahana ma kahi pae kūlike i ka wā o ka fused filament manufacturing (FFF) deposition (kahi ʻano paʻi 3D).
No laila, hoʻokuʻu ʻia ka polymer i hoʻoheheʻe ʻia ma o ka nozzle e ka hoʻemi ʻana i ke kaomi.ʻO ka morphology o ka ʻili, ka hua, ka pololei geometric, nā waiwai mechanical, a me ke kumukūʻai e pili ana i nā mea hoʻololi FFF.
ʻO ka tensile, ka hopena compressive a i ʻole ka ikaika kulou a me ke kuhikuhi paʻi ʻana i manaʻo ʻia ʻo ia ka mea koʻikoʻi o ke kaʻina hana e pili ana i nā laʻana FFF.Ma kēia haʻawina, ua hoʻohana ʻia ke ʻano FFF no ka hoʻomākaukau ʻana i nā specimens;ʻeono mau filament ʻokoʻa i hoʻohana ʻia no ke kūkulu ʻana i ka papa hāpana.
a: ML wanana ana hoʻohālikelike hoʻohālike o nā mea paʻi 3D i nā laʻana 1 a me 2, b: ML wānana ka hoʻohālikelike ʻana o nā mea paʻi kiʻi 3D ma ka laʻana 3, c: ML wānana ʻano hoʻohālike o nā mea paʻi 3D i nā laʻana 4 a me 5. Puna kiʻi: Hossain , MI, etc.
Hiki i ka ʻenehana paʻi 3D ke hoʻohui i ka maikaʻi maikaʻi o nā papahana paʻi ʻaʻole hiki ke hoʻokō ʻia e nā ʻano hana kuʻuna.Ma muli o ke ʻano hana kūʻokoʻa o ka paʻi 3D, hoʻopilikia nui ʻia ka maikaʻi o nā ʻāpana i hana ʻia e ka hoʻolālā a me nā ʻano hana.
Ua hoʻohana ʻia ke aʻo ʻana i ka mīkini (ML) i nā ʻano he nui i ka hana hoʻohui e hoʻomaikaʻi ai i ka hoʻomohala holoʻokoʻa a me ke kaʻina hana.Ua kūkulu ʻia kahi ʻano hana hoʻolālā kiʻekiʻe e pili ana i ka ʻikepili no FFF a me kahi hoʻolālā no ka hoʻolālā ʻana i ka ʻāpana FFF.
Ua manaʻo nā mea noiʻi i ka mahana nozzle me ke kōkua o nā manaʻo aʻo mīkini.Hoʻohana ʻia ka ʻenehana ML no ka helu ʻana i ka mahana o ka moena paʻi a me ka wikiwiki o ka paʻi;ua hoʻonohonoho ʻia ka nui like no nā laʻana a pau.
Hōʻike nā hopena e pili pono ana ka wai o ka mea i ka maikaʻi o ka puka paʻi 3D.ʻO ka mahana nozzle kūpono wale nō e hiki ke hōʻoia i ka pono o ka mea.
Ma kēia hana, ua hui pū ʻia nā mea filament PLA, HDPE a me nā mea filament recycled me nā nanoparticles TiO2 a hoʻohana ʻia no ka hana ʻana i nā mea paʻi 3D haʻahaʻa haʻahaʻa e ke kālepa hoʻoheheʻe filament e hana i nā mea paʻi 3D a me nā extruders filament.
ʻO nā filament hiʻohiʻona he moʻolelo a hoʻohana i ka graphene e hana i kahi uhi wai, hiki ke hōʻemi i nā loli i nā waiwai mechanical kumu o ka huahana i hoʻopau ʻia.Hiki ke hana ʻia ka ʻaoʻao o waho o ka mea paʻi 3D.
ʻO ka pahuhopu nui o kēia hana, ʻo ia ka ʻimi ʻana i kahi ala e hoʻokō ai i kahi ʻoi aku ka hilinaʻi a ʻoi aku ka maikaʻi o ka mīkini a me ke kino kino i nā mea paʻi 3D i hoʻohālikelike ʻia me nā mea paʻi 3D kuʻuna i hana mau ʻia.Hiki i nā hopena a me nā hoʻohana ʻana o kēia noiʻi ke wehe i ke ala no ka hoʻomohala ʻana i nā papahana pili i ka ʻoihana.
E hoʻomau i ka heluhelu: ʻO wai nā nanoparticles maikaʻi loa no ka hana hoʻohui a me nā noi paʻi 3D?
