Ke hoʻohana nei i nā mea hana o ka polokalamu 3D Spark, ua kālailai ka hui i nā mea like ʻole e pili ana i nā kumukūʻai hana.ʻO kekahi o lākou he kiko'ī i nā'āpana, aʻo nā mea'ē aʻe i nā kaʻina hana.No ka laʻana, hoʻonohonoho i nā ʻāpana e hōʻemi i nā kākoʻo a hoʻonui i nā ʻili i kūkulu ʻia.

ʻAʻohe ʻano kaohi o ka paʻi 3D, e hana maʻalahi i nā ʻāpana paʻakikī e like me nā mea maʻalahi.

Eia naʻe, ʻo ke kumukūʻai ponoʻī he holoholona ʻē aʻe.Ma ka ʻoihana aerospace, paʻakikī ka paʻi 3D e hoʻokūkū maoli.
E ʻōlelo wau ʻo ka ʻoihana aerospace kekahi o nā wahi liʻiliʻi i hiki ke hoʻāpono ʻia ke kumukūʻai o ka paʻi 3D metala.ʻO nā kumukūʻai hana mua he hapa liʻiliʻi o ke kumukūʻai o kahi huahana aerospace, a he mea koʻikoʻi ke kaumaha i maʻalahi ke loaʻa kahi hoʻohana no ia.Ke hoʻohālikelike ʻia me nā kumukūʻai kiʻekiʻe o ka hōʻoia ʻana i ka maikaʻi no nā ʻāpana composite, hiki i kahi kaʻina paʻi akamai a me ka nānā ʻana i ke ʻano koʻikoʻi ke hāʻawi i ka mālama kālā maoli a me ka hanu o ka ea hou.

Hiki i nā huahana e like me nā mea hoʻolalelale hou o ka Navy a me nā mea hou hou aʻe he nui nā pale paʻi 3D.ʻO ka pōmaikaʻi o nā ʻāpana topology-optimized ʻo ia ka hoʻopili ʻana i ka ʻike ikaika i loko o ke kaʻina hana hoʻolālā a pili pono ka loiloi luhi.
Eia nō naʻe, aia kekahi manawa ma mua o ka loaʻa ʻana o nā mea e like me DMLS i ka automotive a me ka hana ʻana.ʻOi aku ka liʻiliʻi o ke kaumaha.
ʻO kahi noi kahi e hana maikaʻi ai i loko o nā manifold hydraulic/pneumatic.He mea maikaʻi loa ka hiki ke hana i nā awāwa curved a me nā lua no ka shrink wrap.Eia kekahi, no ka hōʻoia ʻana, pono ʻoe e hana i kahi hoʻāʻo koʻikoʻi 100%, no laila ʻaʻole pono ʻoe i kahi kumu palekana nui (he kiʻekiʻe ke koʻikoʻi).
ʻO ka pilikia, ʻo ka nui o nā ʻoihana e haʻaheo no ka loaʻa ʻana o kahi paʻi SLM, akā kakaikahi ka poʻe ʻike pehea e hoʻohana ai.Hoʻohana wale ʻia kēia mau mea paʻi no ka prototyping wikiwiki a hana ʻole i ka hapa nui o ka manawa.No ka mea, ke manaʻo ʻia nei he wahi hou kēia, manaʻo ʻia e emi nā mea paʻi e like me ka waiū a pono e ʻoki ʻia i loko o 5 mau makahiki.ʻO ia ke ʻano he haʻahaʻa loa ke kumukūʻai maoli, paʻakikī maoli ka loaʻa ʻana o ke kumukūʻai kūpono no kahi hana hana.
Eia kekahi, hilinaʻi ka maikaʻi o ka paʻi ʻana i ka conductivity thermal o ka mea, ʻo ia hoʻi ka hana ʻana o ka aluminika i ka ʻili o ka ʻili e hiki ai ke alakaʻi i ka hana luhi hoʻonāukiuki (ʻaʻole pono ka nui o lākou inā ʻoe e hoʻolālā ana no kēlā).Eia kekahi, ʻoiai ʻo TiAlV6 paʻi maikaʻi loa a ʻoi aku ka ikaika o nā waiwai ma mua o ka papa kumu 5, loaʻa ka alumini ma ke ʻano he AlSi10Mg, ʻaʻole ia ka alloy ikaika loa.ʻO T6, ʻoiai kūpono no ka hoʻolei ʻana o nā mea like, ʻaʻole kūpono ia no nā ʻāpana SLM.He maikaʻi hou ʻo Scalmaloy akā paʻakikī i ka laikini, hāʻawi liʻiliʻi, hiki iā ʻoe ke hoʻohana iā Ti me nā paia lahilahi.

No laila ʻae: hiki i ka ʻoihana aerospace ke pōmaikaʻi mai nā ʻāpana SLM, a hana kekahi o lākou, akā paʻa nā idiosyncrasies o ka ʻoihana a me nā hui e hāʻawi nei i ka lawelawe i nā makahiki 70, kahi mea e paʻakikī iki ai.ʻO ka hoʻomohala maoli wale nō ka ʻenekini, kahi i paʻi ʻia ai nā injectors wahie i mea maʻamau.No mākou iho, ʻo ka hakakā ʻana no ka lako me ASML he kaua piʻi.

ʻO nā kumu ʻē aʻe e pili ana i nā kumukūʻai mīkini ʻo ia ka hoʻokele ʻana i nā poho hoʻomaha ma muli o ka spalling a me ka evaporation.Eia kekahi, pono e hana ʻia nā chips.Hiki ke hoʻemi nui ʻia nā puʻupuʻu i ka hana nui.
Hoʻohana pinepine ʻia kēia ma ke ʻano he hoʻolālā topology, a e like me kāu e manaʻo ai, he pae ʻē aʻe o ka nānā ʻana ma luna o FEA.Loaʻa wale ʻia i nā makahiki i hala iho nei i ka lilo ʻana o nā mea hana.
Ke ʻike ʻoe i ka inoa Fraunhofer, ua patent ʻia a pāpā ʻia ke kaiāulu hana mai ka hoʻohana ʻana iā ia no ka manawa lōʻihi loa.
Ma nā huaʻōlelo ʻē aʻe: ua hana mākou i kahi ala hou e hōʻoiaʻiʻo ai e hoʻololi ʻia kāu kaʻa i ka wā e pau ai kāu palapala hoʻokō.
ʻAʻole wau i ʻike i ka pilina ma waena o nā ʻeke puka māmā a me kahi kipi ʻino e hoʻolei ai i kāu kaʻa holoʻokoʻa i ka ʻōpala?
ʻO ka loiloi ola luhi kekahi mea;inā ʻoe e hoʻonui wale i ka ikaika waiwai, e hoʻopau ʻoe i kahi ʻāpana hana ʻole.
ʻOiai inā ua hoʻolālā lākou i ka nāwaliwali, ʻaʻole ia e luhi ma hope o ka pau ʻana o ka palapala hōʻoia, he hinge wale nō ia, akā he mea hou, a ʻaʻole paha e pono ʻoe e hoʻolei i ke kaʻa holoʻokoʻa ... aia kahi kaʻa kaʻa i ka wā e ola ana ke kaʻa, no ka mea ma ke ʻano he maikaʻi mau, akā ʻaʻohe mea hou e pili ana i kēlā…
I ka hoʻomaʻamaʻa ʻana, no ka hōʻoia ʻana e hoʻokō i nā kūlana palekana a me nā mea ʻē aʻe, ua hana hou ʻia paha ia, e like me ka hapa nui o nā kaʻa/kino/noho, ma muli o ke koʻikoʻi e loaʻa iā ia i ka hoʻohana maʻamau..wahi kūʻai, ke ʻole ke koi ʻia e ke kānāwai ma kou wahi.
“He hinge wale nō ia” akā he laʻana no ka hoʻolālā ʻana i kahi ʻāpana no ke ola kikoʻī.Ke hoʻohana ʻia i ke koena o kāu kaʻa, e lilo kāu kaʻa i clunker no kekahi manawa.
ʻO ka hōʻino ka hopena o kā lākou pale patent pinepine (MP3, ʻike wau!).
Kūkulu ʻia ka hoʻokele waiwai holoʻokoʻa o ʻAmelika ma luna o ia "chip".Ma kekahi mau kūlana hana ia :-/.
Ua hana nui ʻo Fraunhofer i ka ʻepekema.ʻAʻole i hoʻohana wale ʻia, akā no ka noiʻi kumu.Ua pau ke kālā.Inā makemake ʻoe e hana me ka ʻole o nā patent a me nā laikini, pono ʻoe e hāʻawi iā lākou i ke kālā kālā aupuni.Me nā laikini a me nā patent, nā poʻe ma nā ʻāina ʻē aʻe kekahi o nā kumukūʻai no ka mea ua pōmaikaʻi lākou i ka ʻenehana.Eia kekahi, he mea nui kēia mau haʻawina a pau no ka mālama ʻana i ka hoʻokūkū o ka ʻoihana.
Wahi a kā lākou pūnaewele, ʻo kahi hapa o kāu ʻauhau ma kahi o 30% (Grundfinanzierung), ʻo ke koena mai nā kumu i loaʻa i nā hui ʻē aʻe.He ʻāpana paha ka loaʻa kālā patent o kēlā 70%, no laila inā ʻaʻole ʻoe e noʻonoʻo i kēlā, e emi ana ka hoʻomohala ʻana a i ʻole nā ʻauhau.
No kekahi kumu ʻike ʻole ʻia, pāpā ʻia ke kila kila a kaulana ʻole no ke kino, mīkini, hoʻoili a me nā mea hoʻokuʻu.Hiki ke loaʻa wale i nā paipu hoʻopau pipiʻi, e like me ka martensitic AISI 410, inā makemake ʻoe i kahi pauka maikaʻi a paʻa pono ʻoe e hoʻohana iā AISI 304/316 iā ʻoe iho e hana i kahi mea like.
