Te Tānga-ā-ringa (SLA) – Te Kōwhiringa Pai mō te Tānga-3D Tino Tika
Te Whakamāramatanga Stereo (SLA, SL rānei) He hangarau tā 3D tino tika te whakamahi i te kapia whakaahua-ā-ahua hei rauemi mata. Ka whakamahia e tēnei hangarau ngā āhuatanga whakamaroke tere o te kapia whakaahua-ā-ahua i raro i te hihi UV laser motuhake, e āhei ai te hanga pai o ngā hanganga 3D matatini mā te hanga paparanga-i-te-paparanga.
I te wā e hangaia ana, ka tere te whakakotahitanga me te whakapakeketanga o te kapia wai e aro ana ki te hihi UV (tata ki te 250-400nm te roangaru). Ka arotahi tika te mīhini SLA i te taiaho UV ki te mata o te kapia e aro ana ki te hihi UV, ka āta whakamaroke i te kapia mai i te pūwāhi ki te rārangi, kātahi mai i te rārangi ki te mata, kia tutuki ai ngā whakaahuatanga whakawhiti-wāhanga tika o ia paparanga. Papa i te papa, ka hangaia he tauira 3D tino pakari, taipitopito hoki.
He pai ngā painga o te stereolithography pērā i te tino tika o te hanga, ngā mata maeneene, me te whakaputanga taipitopito tino taumira. He whānuitia te whakamahinga i roto i te hanga tauira ahumahi, te hoahoa taputapu hauora, te hoahoa whakapaipai, te hanga pokepokea ai, me te hanga tauira kounga teitei. Mā te tere me te tika o te hanga ka whakapoto i ngā huringa whanaketanga hua, ka nui ake te ngāwari me te auahatanga ki te umanga hanga.
Ehara i te mea he hangarau matua te SLA (Stereolithography) mō te tānga 3D anake, engari he otinga tino whai hua hoki mō te whakatutuki i te tauira kounga teitei me te whakaputa ritenga iti-papa, hei āwhina i ngā kamupene ki te whakatutuki i ngā paerewa teitei ake i roto i te hanga tino tika.
Ngā Resin Whakaahua-ā-Raukati Koreutu:
Ngā Painga: He iti te utu, he tere te whakamaroke, he pakari te āhua, he iti te matotoru
Ngā Huakore: Te aukati nui i te hāora, te whakahekenga nui, te piko o ngā hua tānga, te iti o te tika, me te hiahia mō te whakamaroke tuarua
Ngā Resin Whakaahua-ā-Katio:
Ngā Painga: He iti noa te whakahekenga o te rōrahi i te wā e whakamarokehia ana, he tere tere te tauhohenga, kāore e hiahiatia he whakamaroke tuarua i muri i te whakakoi, kāore e pāngia e te aukati hāora, he pumau āhua pai, he tino pai ngā āhuatanga miihini, me te tino tika
Ngā Huakore: He puhoi te tere o te tauhohenga, he matotoru teitei, he nui te horopeta o te pānga o ngā vinyl ethers, ā, he puhoi te whakamaroke; he pakarukaru ngā epoxies.
Ngā Pūnaha Ranu:
Ka whakakotahi ngā pūnaha ranu acrylate-epoxy i ngā mātāpono whakamaroke e rua kua whakahuatia ake nei, me te mahi tahi a ngā kaiwhakaoho rauropi cationic me ngā kaiwhakaoho rauropi kore utu.
Ka whakarōpūtia ngā kapia tā 3D ki ngā kapia whakaahua-ā-ira kore utu, ngā kapia whakaahua-ā-ira cationic, me ngā pūnaha ranu. Ko Ever Ray, he kaihanga me te 20 tau o te wheako e tohunga ana ki te hanga me te whakawhanake i ngā kapia whakaahua-ā-ira, e whakamanamana ana ki te kaha whakaputa ā-tau o te 20,000 tana, he raina hua whānui, me te kaha ki te whakarite hua. Kei roto i ngā kapia tā 3D ko te Polyurethane 7224-1, 7200, 7296-1, me 7253A-5.
