Paura hangarau tā 3D whakarewaWhakarāpopototanga o te tukanga whakarewa, ko ngā mōhiohio wera, ko te wāhanga tino nui o te mekameka ahumahi tā 3D, koia hoki te uara nui rawa atu. I te huihuinga ahumahi tā 3D o te Ao i te tau 2013, i hoatu e ngā tohunga matua o te ahumahi tā 3D o te Ao he whakamāramatanga mārama mō te paura whakarewa tā 3D, arā, ko te rahi o ngā matūriki whakarewa iti iho i te 1mm. Kei roto ko te paura whakarewa kotahi, te paura koranu me ētahi paura matū ātete me te āhuatanga konganuku. I tēnei wā, ko ngā rauemi paura whakarewa tā 3D ko te koranu cobalt-chromium, te maitai kore waikura, te maitai ahumahi, te koranu parahi, te koranu titanium me te koranu nikara-konumohe. Engari me whai kirihou pai te paura whakarewa tā 3D, engari me tutuki hoki ngā whakaritenga o te rahi matūriki pai, te tohatoha rahi matūriki whaiti, te porowhita teitei, te rere pai me te matotoru wetewete teitei. Nā te rerekētanga o ngā whakaritenga o te tono me te tukanga whakarewa i muri mai, he rerekē anō hoki ngā tikanga whakarite paura whakarewa. E ai ki te tukanga whakarite, ko te nuinga o te wā ko te tikanga matū ā-tinana me te tikanga miihini. I roto i te umanga whakarewa paura, he whānui te whakamahinga o ngā tikanga pēnei i te hikohiko, te whakaiti me te atomization. Heoi, me mōhio kei ngā tikanga e rua ō rāua ngoikoretanga, kāore i te pai mō te whakarite paura koranu. I tēnei wā, ko te paura konganuku mō te hanga tāpiritanga he mea kohikohi nui ki te koranu titanium, te koranu pāmahana teitei, te koranu cobalt-chromium, te maitai kaha teitei me te maitai mate. Hei whakatutuki i ngā whakaritenga o ngā taputapu me ngā tukanga hanga tāpiritanga, me whai āhuatanga te paura konganuku o te iti o te hāora me te hauota, te pai o te nekehanga porowhita, te whānuitanga tohatoha rahi matūriki whaiti me te matotoru nui. I tēnei wā, ko ngā tikanga matua mō te whakarite paura konganuku mō te hanga tāpiritanga ko te irahiko hurihuri plasma (PREP), te atomization plasma (PA), te atomization hau (GA) me te spheroidization plasma (PS), ka taea te whakamahi i ēnei katoa hei whakarite paura konganuku porowhita, tata-porowhita rānei.
