Te kapia whakawhanui tānga 3D

Ko te wāhanga tuatahi o te rangahau i arotahi ki te whiriwhiri i tētahi monomer hei hanga i te kapia polymer. Me taea te whakaora i te monomer e te UV, me poto te wā whakaora, ā, me whakaatu i ngā āhuatanga miihini e hiahiatia ana e tika ana mō ngā tono taumahatanga teitei. Whai muri i te whakamātautau a te tīma i ētahi kaitono e toru, ka whakatau te tīma ki te 2-hydroxyethyl methacrylate (ka karangatia noa e mātou ko HEMA).

I te wā i mau ai te monomer, ka tīmata ngā kairangahau ki te kimi i te kukū pai rawa atu o te photoinitiator me te kaihopu pupuhi tika hei hono i te HEMA. E rua ngā momo photoinitiator i whakamatautauria mō tō rātou hiahia ki te whakamaroke i raro i ngā rama UV 405nm paerewa e kitea ana i roto i te nuinga o ngā pūnaha SLA. I whakakotahihia ngā photoinitiator i te ōwehenga 1:1, ā, i konatunatua ki te 5% mā te taumaha mō te hua tino pai. Ko te kaihopu pupuhi – ka whakamahia hei whakahaere i te whānui o te hanganga pūtau o te HEMA, ka hua ake he 'huka' – he uaua ake te kimi. He maha ngā kaihopu i whakamatautauria he kore e wairewa, he uaua rānei ki te whakaū, engari i te mutunga ka whakatau te tīma ki tētahi kaihopu pupuhi kore-tuku iho e whakamahia ana me ngā polymer rite ki te polystyrene.

I whakamahia te ranunga matatini o ngā kai hei hanga i te kapia photopolymer whakamutunga, ā, ka tīmata te tīma ki te tā 3D i ētahi hoahoa CAD kāore i te tino uaua. I tāia 3D ngā tauira ki runga i te Anycubic Photon i te tauine 1x, ā, i whakamahanahia ki te 200°C mō te tekau meneti. Nā te wera i pirau te matū pupuhi, ka whakahohe i te mahi pahuka o te kapia, ka whakawhānui i te rahi o ngā tauira. I te whakataurite i ngā āhuatanga i mua me muri i te whakawhānui, ka tatauhia e ngā kairangahau ngā whakawhānuitanga rōrahi tae atu ki te 4000% (40x), ka pana i ngā tauira tā 3D ki tua atu i ngā herenga āhuatanga o te pereti hanga o te Photon. E whakapono ana ngā kairangahau ka taea te whakamahi i tēnei hangarau mō ngā tono māmā pēnei i ngā aerofoils, ngā āwhina pupuhi rānei nā te iti rawa o te kiato o te rauemi whakawhānui.
