Kua kite koe i te piki haere o te rongonui o te tānga 3D? Mai i te hanga noa i ngā taonga takaro kirihou iti me ngā tauira ariā i ētahi tau kua pahure ake nei, kua taea e ia te tā i ngā whare, i ngā niho, tae atu ki ngā whekau tangata! He rite tōna whanaketanga ki te rōkete.
Ahakoa tōna rongonui, ki te hiahia pono te tānga 3D ki te ārahi i roto i te hanga ahumahi, kāore e taea te whakawhirinaki anake ki ngā "persimmons ngohengohe" pērā i te kirihou me te kapia. He pai mō te hanga i ngā wāhanga whakaaturanga, engari ina tae ki te hanga i ngā wāhanga pāmahana teitei ka taea te tu atu i ngā taiao tino kino, i ngā taputapu tino kaha, ātete ki te kakahu, he maha ngā rauemi ka kore e pai tonu.
Koinei te wāhi e puta mai ai te kōrero a te toa o tā tātou tuhinga o te rā nei—paura konumohe, e mōhiotia whānuitia ana ko te "corundum." Kāore tēnei rauemi e ngāwari ki te pana, engari he kaha ōna āhuatanga: he pakeke teitei, he ātete ki te waikura, he ātete ki te pāmahana teitei, me te whakamarumaru pai rawa atu. I roto i ngā ahumahi tuku iho, he tohunga kē ia i roto i ngā rauemi ātete ahi, ngā mea whakakoi, ngā uku, me ētahi atu mara.
Nō reira, ko te pātai, he aha te momo mura ka puta ake ina tūtaki tētahi rauemi "pakari" tuku iho ki te hangarau "hangarau mamati atamai" hou? Ko te whakautu: kei te haere tonu tētahi hurihanga rauemi mārire.
Ⅰ. He aha te take o te alumina? He aha i pakaru ai te pokepokea ai?
Tuatahi, me matapaki tātou he aha i kore ai te tānga 3D i pai ake ki ngā rauemi uku i mua. Whakaarohia: he ngāwari noa te whakahaere i ngā paura kirihou, whakarewa rānei ina whakakorikoria, ina whakaputaia rānei mā te whakamahi i ngā laser. Engari he pakarukaru, he uaua hoki te rewa i ngā paura uku. He kuiti rawa te matapihi tukanga o te whakakorikoria e ngā laser, kātahi ka hangaia, ka ngāwari ai te pakaru me te whakarerekē i te āhua, ka iti rawa te hua.
Nā, me pēhea te whakaoti rapanga a te alumina i tēnei raruraru? Kāore e whakawhirinaki ana ki te kaha o te ringa, engari ki te "mōhiotanga".
Ko te putanga matua kei roto i te whanaketanga taurite o te hangarau tā 3D me ngā hanganga rauemi. Ko ngā hangarau matua o nāianei, pērā i te pupuhi hononga me te stereolithography, e whakamahi ana i te "huarahi piko".
Te pupuhi hononga: He mahi tino mohio tēnei. Kāore i rite ki ngā tikanga tuku iho o te whakarewa tika i te paura konumohe waikura ki te laser, ka pania tuatahitia e tēnei tikanga he paparanga angiangi o te paura konumohe waikura. Kātahi, pērā i te pūreretā waituhi tino tika, ka rehu te pane tā i tētahi "piripiri" motuhake ki te wāhi e hiahiatia ana, ka herea te paura. Mā tēnei paninga paparanga-i-te-paparanga o te paura me te piripiri ka puta he "tinana matomato" āhua tuatahi. Kāore anō kia totoka tēnei tinana matomato, nō reira, pērā i ngā uku, ka pāngia e te "iriiritanga ahi" whakamutunga i roto i te oumu pāmahana teitei—te whakahinuhinu. I muri i te whakahinuhinu ka tino piri ngā matūriki, ka tutuki ngā āhuatanga miihini e tata ana ki ngā uku tuku iho.
Mā tēnei ka karohia ngā wero o te whakarewa tika i ngā uku. He rite ki te hanga i te wāhanga mā te tānga 3D, kātahi ka whakakīia ki te wairua me te kaha mā te whakamahi i ngā tikanga tuku iho.
II. Kei hea te tino putanga mai o tēnei "ahunga whakamua"? He kōrero noa iho te kōrero me te kore mahi.
Ki te mea he putanga hou tēnei, me whai pūkenga tūturu, tika? Ina hoki, ko te whanaketanga o te paura konumohe waikura i roto i te tānga 3D ehara i te mea "mai i te tīmatanga" anake, engari he "mai i te pai ki te tino pai", he mea e whakatau ana i ngā raruraru maha kāore i taea te whakatau i mua.
Tuatahi, ka whakakorea te ariā o te "uaua" hei kupu whakarite mō te "utu nui." I ngā wā o mua, ko te tukatuka i ngā uku alumina, pērā i ngā pūwero, ngā whakawhiti wera rānei me ngā awa rere ā-roto matatini, e whakawhirinaki ana ki te hanga pokepokea ai, ki te miihini rānei, he mea utu nui, he mea pau te wā, ā, kāore e taea te hanga i ētahi hanganga. Engari i nāianei, mā te tā 3D ka taea te hanga tika, "kore pokepokea ai" o tētahi hanganga matatini ka taea e koe te hoahoa. Whakaarohia he wāhanga uku alumina me te hanganga honikoma biomimetic ā-roto, he tino māmā engari he tino kaha. I roto i te umanga rererangi, he "patu makutu" pono tēnei mō te whakaiti i te taumaha me te whakapai ake i te mahi.
Tuarua, ka tutuki i a ia te "whakaurunga tino pai o te mahi me te āhua." Ko ētahi wāhanga e hiahia ana ki ngā āhuahanga uaua me ngā mahi motuhake pēnei i te ātete pāmahana teitei, te ātete kakahu, me te whakamarumaru. Hei tauira, ko ngā ringa here uku e whakamahia ana i roto i te umanga semiconductor me mama, ka taea te neke tere, me te tino ātete-pūmau me te ātete kakahu. Ko te mea i hiahiatia i mua kia maha ngā wāhanga kia huihuia ka taea inaianei te tā tika 3D mai i te alumina hei wāhanga kotahi, whakauru, ka whakapai ake i te pono me te mahi.
Tuatoru, ka puta mai he wā koura mō te whakaritenga whaiaro. He mea tino whakamiharo tēnei i roto i te ao hauora. He rerekē rawa ngā wheua tangata, ā, he rite tonu ngā rahi o ngā wheua horihori o mua, ā, me whakamahi noa ngā tākuta i ēnei i te wā pokanga. Ināianei, mā te whakamahi i ngā raraunga matawai CT mai i te tūroro, ka taea te tā tika i te 3D i tētahi whakaurunga uku alumina porous e tino ōrite ana ki te āhua o te tūroro. Ehara i te mea he māmā noa iho tēnei hanganga porous engari ka taea hoki e ngā pūtau wheua te tipu ki roto, ka tutuki ai te "osseointegration" tūturu, ā, ka waiho te whakaurunga hei wāhanga o te tinana. Kāore i taea te whakaaro i mua i tēnei momo otinga hauora ritenga.
III. Kua tae mai te heke mai, engari he maha ngā wero.
Ae, kāore e taea te kōrero noa iho. Ko te whakamahinga o te paura alumina i roto i te tānga 3D he rite tonu ki tētahi "mea whakamiharo" e tipu haere ana, he nui te pūmanawa engari he maha ngā wero mō te taiohi.
He nui tonu te utu: He tino utu nui te paura alumina porowhita parakore e tika ana mō te tānga 3D. Tāpirihia ki tēnā ko ngā taputapu tā motuhake e hia miriona tāra te utu me te whakapaunga pūngao o te tukanga sintering i muri mai, ka nui tonu te utu mō te tā i tētahi wāhanga alumina.
Ngā arai tukanga teitei: Mai i te whakarite paru me te whakatakoto tawhā tā ki te tango i ngā here me te whakahaere i te pihi tukatuka muri, me whai tohungatanga hohonu me te kohikohi hangarau i ia taahiraa. Ka ngāwari te puta o ngā raruraru pēnei i te pakaru, te whakarerekētanga, me te whakahekenga kore taurite.
Te ōritetanga o te mahi: He arai nui te whakarite kia ōrite ngā tohu mahi matua pēnei i te kaha me te mātotoru puta noa i ia puranga o ngā wāhanga kua tāia mō ngā tono tauine nui.
