Ke kamaʻilio mākou e pili ana i ka hana hoʻohui a me nā mea hana, manaʻo pinepine mākou i ka plastic a me ka metala.Eia naʻe,Paʻi 3Dua ulu nui nā huahana kūpono i nā makahiki.Hiki iā mākou ke hoʻohana i nā ʻano mea maka no ka hana ʻana i nā ʻāpana, mai ka ceramics a i ka meaʻai a hiki i nā hydrogels i loaʻa i nā cell stem.ʻO ka lāʻau kekahi o kēia mau ʻōnaehana mea hoʻonui.
I kēia manawa, hiki ke hoʻohālikelike ʻia nā mea lāʻau me ka filament extrusion a me ka ʻenehana moena pauka, a ʻoi aku ka kaulana o ka paʻi lāʻau 3D.
Wahi a kekahi hōʻike i paʻi ʻia e Nature magazine, ua nalowale nā ​​kānaka he 54% o ka nui o nā lāʻau ma ka honua.He mea weliweli maoli ka hoʻopau ʻana i ka ulu lāʻau i kēia lā.He mea nui e noʻonoʻo hou i ke ʻano o ka ʻai ʻana i ka lāʻau.ʻO ka hana hoʻohui ʻana paha ke kī i ka hoʻohana mau ʻana i ka lāʻau, no ka mea, he ʻenehana hana ia e hoʻohana wale i nā mea pono, a hiki ke hoʻohana i nā mea hana hou e hoʻolālā i nā mea.No laila, hiki iā mākou ke paʻi i nā ʻāpana 3D.Inā ʻaʻole pono lākou, hiki iā mākou ke hoʻohuli iā lākou i nā mea maka e hoʻomaka i kahi pōʻai hana hou.

lāʻau extrudedPaʻi 3D kaʻina hana
ʻO kahi ala e paʻi ai i ka lāʻau ma 3D ʻo ka hoʻokuʻu ʻana i nā filament.Pono e hoʻomaopopo ʻia ʻaʻole 100% kēia mau mea i hana ʻia i ka lāʻau.Loaʻa iā lākou he 30-40% fiber lāʻau a me 60-70% polymer (hoʻohana ʻia e like me ka hoʻopili).ʻO ke kaʻina hana paʻi lāʻau 3D ponoʻī he hoihoi loa.No ka laʻana, hiki iā ʻoe ke hoʻāʻo i nā wela like ʻole o kēia mau uea e hana i nā kala like ʻole a me nā hoʻopau.I nā huaʻōlelo ʻē aʻe, inā piʻi ka extruder i kahi wela kiʻekiʻe, e ʻā ka lāʻau lāʻau, e hopena i kahi leo ʻeleʻele i ka ʻōpala.Akā, e hoʻomanaʻo, hiki ke hoʻopau ʻia kēia mea.Inā wela loa ka nozzle a ʻaʻole wikiwiki ka wikiwiki o ka hoʻokuʻu ʻana i ka uea, e pōʻino paha ka ʻāpana i paʻi ʻia a i ʻole ke ahi.
ʻO ka pōmaikaʻi nui o ka silika lāʻau, ʻo ia ke ʻano, ka manaʻo a me ke ʻala e like me ka lāʻau paʻa.Eia kekahi, hiki ke pena maʻalahi i nā paʻi, ʻokiʻoki a hoʻoliʻi ʻia i mea e ʻoi aku ka ʻoiaʻiʻo o ko lākou mau papa.Eia nō naʻe, ʻo kekahi o nā hemahema i ʻike ʻia ʻo ia ka mea ʻoi aku ka palupalu ma mua o ka thermoplastic maʻamau.No laila, maʻalahi lākou e wāwahi.
ʻO ka ʻōlelo maʻamau, ʻaʻole e hoʻohana ʻia kēia mea i loko o ka ʻenehana ʻoihana, akā no ka honua hana, kahi i hoʻohana ʻia ma ke ʻano he leʻaleʻa a mea hoʻonaninani paha.ʻO kekahi o nā mea hana fiber lāʻau nui ʻo Polymaker, Filamentum, Colorfabb a i ʻole FormFutura.
Hoʻohana i ka lāʻau i ke kaʻina hana moena pauda
No ka hana ʻana i nā ʻāpana lāʻau, hiki ke hoʻohana ʻia ka ʻenehana moena pauka.I kēia mau hihia, hoʻohana ʻia kahi pauda ʻeleʻele maikaʻi loa i haku ʻia me ka ʻōpala, a ʻo ka ʻili he one.ʻO kekahi o nā ʻenehana kūpono loa i kēia kahua ʻo ia ka pulupulu adhesive, ka mea kaulana loa no Desktop Metal (DM).Ua wehe ʻo DM i kahi puka hou i ka honua hana hoʻohui ma hope o ka hui pū ʻana me Forrust.ʻO ka ʻōnaehana paʻi "Shop System Forest Edition" i hoʻomohala ʻia e nā mea ʻelua e hiki ai i ka lehulehu ke hoʻohana i ka Binder Jetting no ka paʻi lāʻau 3D.
Hiki i kēia ʻōnaehana paʻi ke paʻi 3D i nā ʻāpana lāʻau hoʻohana hope i hana ʻia mai ka lāʻau recycled.Hoʻohana ka ʻenehana hana maoli i nā ʻāpana sawdust a me nā mea hoʻopili i ke kaʻina o ka mana kamepiula.Me ka hoʻohana ʻana i ka ʻōnaehana hana papa-a-papa, hiki ke hana i nā ʻāpana lāʻau i paʻakikī ke hoʻokō ʻia e nā ʻano unuhi kuʻuna a pau ʻole.ʻIke loa, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o kēia ʻenehana ma mua o ke ʻano o ka filament extrusion method.Eia naʻe, pono e noʻonoʻo ʻia kēia no ka mea ʻoi aku ka maikaʻi o ka ʻili o ka hopena hope ma mua o ka ʻāpana FFF i paʻi ʻia.
Ma waho aʻe o ka noʻonoʻo ʻana he ʻano hana hana lāʻau hoʻomau, hiki i ka paʻi lāʻau 3D ke hoʻoponopono i nā pilikia he nui.Hoʻopili kēia mai ka hoʻihoʻi ʻana o ka mōʻaukala a hiki i ka hana ʻana i nā waiwai waiwai, i ka hoʻohana ʻana i kēia mau mea kūlohelohe ʻaʻole i noʻonoʻo i nā huahana hou.No ka mea he hana kikohoʻe ia, hiki i nā mea hoʻohana me ka ʻole o ka hana kamana ke hauʻoli i nā pono o ka lāʻauPaʻi 3D.
