Ko ngā rerekētanga o ngā tikanga e hāpai ai i ngā takotoranga ki waenganui SLS powders me FDM filaments e whai pānga nui ana ki ā rātou mahi i ngā whakamahinga whakaprint 3D. I roto i SLS (Selective Laser Sintering), ko tētahi rātā e hāpai i te pātītī pāpaku takotoranga anō hoki, e hāngai ai ki te whakapapa kaha o te takotoranga. Kei te tikanga e hanga ana i ngā wāhanga e ōrite ana te kaha me te whai whakapapa hohonu. I te tāpiri, ko FDM (Fused Deposition Modeling) he whakaputanga i ngā āhua thermoplastic me te whai whakapapa i te whakakaha o ngā takotoranga kua rungaia hei hanga i tētahi mea taumaha. Ko tēnei e āwhina ai i ngā ahuatanga mekanik huinga, i reira anō pea ka whakapapa kāore i te kaha o ngā takotoranga ki raro i ētahi tikanga pēhi, e āwhina ai i te tōaitanga ki ngā whakamahinga e herea ai te pēhi.

Ko ngā whakaaro mai i ngā whakamātau whakaeke e toa ana ko te kaha o ngā wāhanga SLS e whai ana i te kaha o te hokinga tūturu mai i te whakauru tino o ngā paraihe pāpaku, e tino whai kiko ana ki te thermoplastic taapiri. I te tērā, ko ngā wāhanga FDM ka hiahia pea ki ētahi atu whakaaro hoahoa hei whakapai ake i te hokinga o ngā papanga, pērā i te whakapai ake i te wāhi pāpaku me te teitei o ngā papanga. Ko te rerekētanga o te kaha o ngā hokinga e whai tikanga ana i te whiriwhiri i te hangarau e hāngai ana ki ngā whakamahinga mutunga, me te SLS e tino paihia ana mō ngā wāhanga e hiahia ana ki te whakaeke me te whirinakitanga teitei ake.

Te kounga o te otinga mata i runga i ngā hangarau

Ina arotake ana i te kounga o te mata kua eke ai te hanganga SLS ki te whakamātau FDM, he maha ngā āhuatanga, tae atu ki te whakatau me ngā tikanga tōtika, e uru mai ana. Ko te SLS e tuku ana i te mata kounga pai ake nā te whakatau tata ki te tukanga, nā te mea ka taea e ngā pātītī para kawe i te mata māmā ki runga i ngā wāhanga whakaputua kaua ko ngā tautoko hanganga. Ko te whakatau tata he painga mō ngā wāhanga e hiahiatia ana ngā taapiri pāpaku me te kounga mata whakahirahira, pērā i ngā wāhanga hauora, rānei wāhanga waka hōkio.

Ko ngā tauira kei te tōaitanga o ngā umanga i whakaatu ai i te pānga o te kounga o te mata ki te whakaaetanga o te hua. Hei tauira, ki ngā hua kaihoko, ko te hiahia ki te mata parurenga ka arahi i ngā kaihanga ki te whiriwhiri i te SLS i runga i te FDM. Ahakoa e mōhao ana ngā mata FDM pea nā ngā raina takotoranga e korekore ai i muri i te tuhi, ko ngā tikanga whakawhitinga whakamua pērā i te āpiti noa rānei te āpiti hauhake e āwhina ai i te kounga mata. Ko te whiriwhiri i waenganui SLS me FDM e noho pū ana ki te taunekeneke i waenganui i te kounga tuhinga tuatahi, ngā here whakawhitinga i muri, me ngā here motuhake o te whakamahinga o te hua mutunga.

Te Whiriwhiri I Ngā Momo Mātāpuna Mō Ngā Tauira Mahi Tonu vs. Ngā Wāhanga Kaimahi

Ko te whiriwhiri i waenganui i ngā pōmera mō te SLS me ngā metara mō te LPBF he nui te hāngai ki te whāinga o te tā, ahakoa ko te pūtau angitu, ko te wāhi whakamutunga rānei te wāhi e whakamahia ana. Ko te SLS ka whakamahi i ngā pōmera pērā i te PA12 me te PA11, e whakarato ana i te whanui me te whakakaha ki te whakapai ake i ngā taonga tuatahi, he tino pai mō te angitu tuatahi i te wā e huringa whakapai ana. Hei tauira, i roto i te angitu aunoa, ko te SLS e whakarato ana i ngā wāhanga māmā e taea ai te whakapai anō i te tere kāore he utu pērā i te metara. Ko te kātata, ko te kaha ake o te LPBF ki te whakaputa i ngā wāhanga metara kīato, pērā i te titanium, Inconel rānei e tino pai ana mō ngā whāinga whakamutunga e hiahiatia ana te kaha o te kaha me te whakapae. Ko ngā umanga pērā i te hōkio hau e whai rawa nui ana i te LPBF, ka whakamahi i te whakaputa i ngā wāhanga matua e tino whakapae ana i ngā tikanga tino, e whakaatu ana i te wehenga o ngā matāpuna e pā ana.

Te Ukaipotanga o te SLS Nylon vs. Ngā Paraihe Metara o te LPBF

Ina whai mōhio koe ki te utu whai hua, ko te SLS nylon he kōwhiringa tāone nui mai i tana iti ake i ngā utu rauemi tērā i ngā pātītī metara LPBF. Ko ngā pātītī thermoplastic e whakamahia ana i te SLS he iti ake te utu, ā, ko te tikanga anō hoki he whai hua ake i te rauemi nō te mea ka taea te whakarewa anō i te pātītī kāore i te sintered—he āhuatanga nui tēnei e heke ai te parurenga me te utu katoa. E ai ki ngā ripoata o te ahumahi, he iti ake te utu i ia wāhanga mō te SLS, ā, he tino nui ake te nui o te whakamahinga o ngā rauemi i ngā wa e hiahiatia ana ngā huihuinga. I te tata, ahakoa he nui ake te kaha o te LPBF me te performance o ngā wāhanga, ko te whakamahi i ngā pātītī metara utu nui me te nui ake hoki te kaihāngai i te hiko e pāngia ai te utu tūhono me te whakahaere. I ngā whakamahinga pērā i te hauwai me te hauora, ka tūhono pea ngā kamupene ki te performance i runga i te utu, ka whiriwhiri i te LPBF ahakoa te utu nui, ā, he tino pāngia hoki pea te hua o te hua ki te haumaru me te whai hua.

Ngā Whakamahinga e Hīkina ai ngā Kōwhiringa Rauemi SLS: Wāhi Rererangi ki te Hauoranga

Ko te Whakaputanga Ruaeko Kōwhiringa (SLS) e whai whakamahinga nui ana i ngā umanga rereke pērā i te umanga rererangi, te umanga motukā, me te umanga hauoranga, kaua ko ngā eke rauemi motuhake. Hei tauira, kei te umanga rererangi, ko ngā rauemi pērā i te PA 2241 FR e āhua whakamahia ana nā te iti rawa o te taumaha me te roa o te ora, e tika ana mō ngā wāhanga pīroiroi e noho ana ki ngā whakapāinga teitei. Kei te umanga motukā, ko te āhua o SLS e āwhina ai i te hanga wāhanga pērā i ngā arataki ki te āhua pīroiroi mai i ngā rauemi pērā i te nylon e whakapai ake ai i te mahi me te haumaru o te waka. I te wā kotahi, ko te umanga hauoranga e whai painga ana i ngā rauemi SLS pērā i ngā pōhiri e whakaaetia ana mō te takotoranga tuatahi me te whakamahinga mutunga. I tētahi pūrongo a MarketsandMarkets i whakaatu mai i te mākinga mātātoko e eke ana ki te USD 62.79 piriona tau ki te tau 2026, e āwhina ana i ēnei umanga nā te nui ake o te whakamahi i ngā rauemi SLS matua hōu.

Ngā Āhuatanga Whakamana i te Whakamahinga Rua o ngā Rauemi SLS

Ko te whakamana i te tauhokohoko SLS he mea hau te nuinga e ngā tikanga whakamahi anō i ngā rauemi, e whakapāngia ai te otinga o te rauemi. Ko te āhua motuhake o te tikanga SLS, e whakaae ana kia whakamahia anō ngā para kāore i whakamahia, he iti noa te pānga ki te paraurau me te utu. E ai ki ngā rangahau e whakaputua ana i te Journal of Cleaner Production, he iti ake te pānga a SLS ki te karaihana nā te āhua e whakamahi anō ai i ngā para, ina heke i te 50% te tere o te whakamahi anō. Ko tēnei e whakapai ake ai i te whakamahi rauemi, e hāngai ai kia pai ake te SLS i ngā tikanga hahua kaiwhakaputa hoki, me ētahi atu tikanga hahua anō. Mā te whiwhi i ngā rauemi e hāngai ana ki te taiao me te whakauru ki ngā tikanga whakamahi anō, ka taea e ngā umanga e whakapai ake i te whakamana o ngā tikanga SLS.
