Ko te Melting Laser Kōwhiri (SLM) he hangarau tāpoi hou e whakamahi ana i te rātā hiko kaha ki te paraihe me te whakakaha i ngā rerehua metā ki ngā āhua 3D pūmau. E āwhina ana i ngā umanga pērā i te hauāpora me te motukā ki te eke tōtika i ngā āhua tātaritanga me ngā hoahoa kia māmā ake ai te mahi me te whakapai ake i te whakamahinga kora. I tua atu, ko te SLM e mōhiotia ana mō te whakamahinga rite o ngā rauemi, e whakaatu ana i te tūponotanga o te iti i te paraihe e 90%. Ko tēnei whakamahinga rite nā te āheinga o te SLM ki te whakahaere tino tika i te whakaputanga o ngā rauemi, ka whakamahia anake te mea e hiahiatia ana hei hanga i te wāhanga.
Ko te Tōtuhinga Raseri Metā Tūturu (DMLS) he hangarau tata ki te SLM, engari ka whakahaere ki te tōpuni iti ake, e whakaae ana i te tōtuhinga, kaua ko te whakaputu tino o ngā raihe metā. E hōhonu ai te DMLS ina hanga pānga pīroiroi, āhuatanga tino whaihua. Ko tana kaha ki te waihanga i ngā āhuatanga reka kaua ko te whakaputu tino e whakamahia ai te kōwhiringa tino mō ngā tāone e hiahiatia ana kia ōrite te whaihua, pērā i ngā whakauru hauora me ngā taputapu. Ko tētahi purongo hou a te umanga e tohu ana i te whakamahi ake haere a DMLS i ngā tāone hauora nā tēnei āhuatanga matua, e hāngai ake ana i te ōrite o ngā taputapu hauora, e whai hauora ake ana, me te whai hua ake mō te whakamahi e ngā kaiwhai.
Ko te rerekētanga matua i waenganui i SLM me DMLS ko ō rātou wā māmātanga me ngā tikanga e whakamahia ana; ka eke a SLM ki te hohonu hohonu i ngā pātītīni metā, i te wā e whakamahi ai a DMLS tētahi tikanga hohonu. Ko te wehenga tēnei e āwhina ana i ngā rerekētanga ki te kaha o ngā papanga, ngā nekehanga o te hohonu, me ngā tere whakakōpō, e pa ana ki ngā āhua o te hua mutunga. I whakatau ngā kaiwhaipā whai mōhio kei te taea e SLM te whakaputa i ngā wāhanga kia nui ake te kaha o te pātītī i DMLS, e pa ana ki te mahi whaitua katoa me ngā āhua o te taraiwa. Ko ngā rerekētanga o te kaha he mea nui ki ngā umanga e hiahiatia ana te whakamāmā me ngā āhua e taea ai te utu, e whakatau nei i te kōwhiringa i waenganui i ēnei whārangi whakarewa 3D.
Ko te whakamātao irirangi kōwhai (SLM) e āhua whai hua ana ki ngā paraihe pērā i ngā momo titanium me ngā momo paraihe kaha, e whai ana i ngā āhuatanga kaha me te māmā o te taumaha. Ko te āhua whai hua ake nei he mea nui ki ngā umanga pērā i te umanga waka ātea, kei reira te nuinga o te taumaha e murua ana i te wa e whai hua ana te whakautu. Kua whakaaturia e ngā rangahau ka whai ake ngā wāhanga titanium i hangaia ki te SLM i ngā āhuatanga mekameka e ōrite ana, neke ake rānei i ngā tikanga tawhito. No reira, kua noho hei tikanga matua te SLM mō te hanga i ngā wāhanga e hiahiatia ana kia kaha te kaha me te māmā o te taumaha, e āwhina ana i te whai hua hou ki ngā whakamahinga waka ātea.
Ko te Tōtuhinga Raseri Metā Tūturu (DMLS) he tōtika rawa atu ki te tukatuka i ngā metā pērā i te whiti kātata me ngā rīwai metā rereke, īt especiallya i ngā wāhi e hiahiatia ana te whiti pakanga. Ko ēnei metā kua whakamahia whānuitiaa i ngā umanga hiko me te umanga waka rererangi, i reira ko te whiti pakanga te mea nui. Kātahi ka whai mōhio e ngā tohunga umanga he tino whiti pakanga ake ngā wāhanga DMLS tērā i ngā wāhanga hangaia ki te tikanga. Ko tā te DMLS he māmātia mō ngā whakamahinga e hiahiatia ana te whiti pakanga roa.
I te whakawhitinga i te hihiani me te kaha o ngā wāhanga i hangaia ki te SLM me te DMLS, ētahi rerekētanga ka tū ake. Ko ngā wāhanga SLM e eke ana ki te 100% teitei o te tāpiritanga, e whakarato ana i ngā āhua mekanik hoki pērā i te kaha tōnuitanga me te kaha ki te mōmona. I te wā kotahi, ka eke ngā wāhanga DMLS ki te 98% teitei, e taea ana e te pā ki te mahi mekanik mena ko te tika te mea nui. Ko ngā tātari whakawhitinga e whakaatu ana i te pikinga ake o SLM ki te whakaratonga i ngā wāhanga me te kaha mekanik tino pai, e pai ake ai mō ngā whakamahinga e hiahiatia ana ēnei āhua.
Ko te whakamahi i te Miringa Rā Laser Kōwhai (SLM) e whānuitia ana i te ahumahi rererangi hei hanga i ngā wāhanga māmā, kei te matua nui hoki te pānga ki te whakaiti i te whakamahinga kora. Ko ngā wāhanga matua pērā i ngā rāwhiti turubine e paingia ana e SLM nā te mea e wātea ana tēnei hangarau i te hanga i ngā āhua pīroiroi e whakapai ake ai i te āpiti. Ko ngā raraunga mai i ngā kamupene rererangi e whakaatu ana ko te whakamahi SLM e māmā ai te whakaiti i te taumaha ki te 30% ina whakaritea ki ngā tikanga hanga tawhito. Ko te whakaiti i te taumaha e whakapai ai i te mahi tūturu, engari ko te whakapai hoki i te mahi whānui me te whai mōhio o ngā rererangi.
Ko te Whakapumau Kiriata Rino me te Laser (DMLS) kei te nui ake te whakamahinga ki te ao hauora, e whakarato ana i ngā whakautu biocompatible mō ngā taonga huinga me ngā taputapu mātā. Ka whakamahi ngā taputapu pērā i te titanium me te cobalt-chromium, e whakamahia ana i te nuinga o te wā nā te whakakotua o ērā ki ngā whatu tangata. Kua whakatau ngā whakauru hauora ko ngā taonga huinga kua hangaia ki te DMLS he pai ake te whakauru ki te kōiwi me te whatu, nui ake te kaha o te hanganga poro. Kua whakawhanui ake i te maha o te whakauru ki te kōiwi tērā i ngā taonga huinga tawhito, e whakapai ake ana i te whakapono me te mahi ake mō ngā paitini e whiwhi ana i ēnei taputapu hauora hōu.
Ko ngā hangarau SLM me DMLS e āwhina ana i te tāone waihanga waka ki te whakarite i te tōwari e hāngai ana ki te whakaputa tika me te whakahaere utu. I te wā e SLM kei te nui ake te whai pānga ki ngā whakaputanga iti e hiahiatia ana kia rerekētia, ko DMLS kei te whakamahia mō te whakaputanga nui pea nā tana tere ake. E ai ki te tautohenga o te maakete, kei te whakamahia haere ēnei hangarau tapa ki te whakaputa i ngā wāhanga taputapu whakapapa ki ngā utu iti ake e ngā kamupene waka. Ko te huringa nei e ārahihia ana e te hiahia ki ngā whakaeke hou hei whakaputa i ngā wāhanga tāpiri ki te tika tino ake i te wā e pupuri ai i ngā utu whakaputanga.
He mea nui te mārama ki ngā tikanga utu mō ngā kamupene e whai ana i ngā ratonga whakaputa 3D metara pērā i te SLM me te DMLS. Ko te SLM (Selective Laser Melting) he nui ake ngā utu i te DMLS (Direct Metal Laser Sintering) nā te nui ake o ngā utu hiko me ngā rawa. E hōhonu ai i te DMLS hei kōwhiringa utu-ā-hau pai ake mō ngā tikanga whakaputa nui. Ko ngā tātaitanga e whakaatu mai ana ko te rerekētanga o ngā utu ratonga tuatahi, e rua ngā hanganga e tuku ana i te uara roa atu i te utu tuatahi. Me mātua whai mōhio ngā kamupene ki te tātai utu-ā-herenga i runga i ō rātou whakaritenga whakaputa motuhake.
Ko te mutunga mata o ngā wāhanga i hangaia e SLM me DMLS e taea hoki te whakapā ki ngā here o muri me te mutunga o ngā kaupapa. Ko te nuinga o te wā he hiahiatia ngā mahi mutunga kia rite ki te mata rerehua, nō reira he iti noa ngā tōaitanga e hiahiatia ana. I te tauwehe, ko DMLS e hua ana i te mutunga mata iti ake i te tīmatanga, e whakaiti ai i te hiahia ki ngā mahi a muri. Kua whakaaturia e ngā tātari ko te nuinga o ngā kamupene kei te whai mātāpuna ki te kounga mata i ā rātou whakatau, ina hiahiatia ana te pānga o te mata ki te mahi ake o te hua, ā, ko ngā umanga e nui ana te hiahiatia o te kounga mata.
Ko te āheitanga o te SLM me te DMLS he āhuatanga matua ina whiriwhiri ana i te hangarau hei whakamahi mō te hui haere mai i te whananga iti ki te whananga rahi. Kei te tuku a DMLS kaha ake i te āheitanga, e āwhina ana i te hui haere i te rahi nui i runga i ana wā poto ake. I ngā wā katoa, ko te SLM he tino tāone ki ngā tono whananga motuhake ina hiahiatia ana he whiriake kaha ake. Kua whakaaturia e ngā whakawhitinga keehu kua neke atu i te whananga ki te whananga, kua mōhiotia mā te DMLS mō tana mahi whaihua ki te whakahaere i ngā rahi whananga rahi ake, e whakaatu ana i tana āki ai i ngā taiao whananga tipu.
