Ko te whakapūtātanga whakaahua-pūtāhui, arā, ko te stereolithography taiaho, SL/SLA rānei, te hangarau tā 3D tuatahi i te mākete. Nā Chuck Hull i hanga i te tau 1984, i patent i te tau 1986, ā, nā reira i whakatū a 3D Systems. Ka whakamahia e te tukanga he hihi taiaho hei whakapūtāhui i tētahi rauemi monomer whakaahua-kaha i roto i tētahi pūtāhui. Ka piri ngā paparanga whakapūtāhui (kua whakamaroketia) ki tētahi pereti hanga e neke ake ana, e heke iho ana rānei i runga i te taputapu, ka taea ai te hanga i ngā paparanga whai muri. Ka taea hoki e ngā pūnaha SLA te whakaputa i ngā wāhanga tino iti me te tika mā te whakamahi i tētahi diameter hihi taiaho iti, i roto i tētahi tukanga e mōhiotia ana ko te micro SLA, µSLA rānei. Ka taea hoki e rātou te whakaputa i ngā wāhanga tino nui mā te whakamahi i tētahi diameter hihi nui ake me ngā wā whakaputa roa ake, i roto i ngā rahinga hanga neke atu i te rua mita pūtoru.
I whakaurua mai te pūreretā SLA-1 Stereolithography (SLA), te pūreretā 3D arumoni tuatahi, e 3D Systems i te tau 1987.
He maha ngā momo hangarau whakapūtātanga whakaahua-pūtātanga e wātea ana i ēnei rā. Ko te tuatahi i puta mai i muri i te SLA ko te DLP (Mamati Marama Tukatuka), i whakawhanakehia e Texas Instruments, ā, i kawea mai ki te mākete i te tau 1987. Engari i te whakamahi i te hihi laser mō te whakapūtātanga whakaahua-pūtātanga, ka whakamahia e te hangarau DLP he pūwhakaata rama mamati (he rite ki te pūwhakaata pouaka whakaata paerewa). Nā tēnei ka tere ake i te SLA, nā te mea ka taea e ia te whakapūtātanga whakaahua-pūtātanga i te paparanga katoa o te mea i te wā kotahi (e kiia ana ko te tukanga "papatahi"). Heoi, ko te kounga o ngā wāhanga e whakawhirinaki ana ki te taumira o te pūwhakaata, ā, ka heke i te piki haere o te rahi.
Pērā i te whakaputa rauemi, i ngāwari ake te whakamahi i te stereolithography nā te wātea mai o ngā pūnaha utu iti. Ko ngā pūnaha utu iti tuatahi i ahu mai i ngā tukanga SLA me te DLP taketake. Heoi, i ngā tau tata nei, kua puta mai he whakatupuranga hou o ngā pūnaha tino iti te utu, kiato i runga i ngā pūtake rama LED/LCD. Ko te whanaketanga o muri mai o te photopolymerization vat e mōhiotia ana ko te photopolymerization "tonu" "kore paparanga" rānei, e ahu mai ana i te hoahoa DLP. Ka whakamahia e ēnei tukanga he membrane, ko te hāora te tikanga, hei whakahohe i ngā tere whakaputa tere me te tonu. I rēhita tuatahitia te patent mō tēnei momo stereolithography i te tau 2006 e EnvisionTEC, he kamupene DLP kua tapaina anō ko ETEC, whai muri i tana hokonga mai e Desktop Metal. Heoi, ko Carbon, he kamupene kei Silicon Valley, te tuatahi ki te hokohoko i tēnei hangarau i te tau 2016, ā, mai i taua wā kua whakatūria ia hei kaiārahi i te mākete. Ko te hangarau a Carbon, e mōhiotia ana ko DLS (Digital Light Synthesis), e tuku ana i ngā reiti hua teitei ake me te kaha ki te whakaputa wāhanga me ngā rauemi ranu pakari, me te whakakotahi i ngā thermosets me ngā photopolymers. Kua whakauru mai hoki ētahi atu kamupene i ngā hangarau ōrite ki te mākete, pērā i a 3D Systems (Pikitia 4), Origin (he wāhanga inaianei nō Stratasys), LuxCreo, Carima, me ētahi atu.
