Vat photopolymerization, kunyanya laser stereolithography kana SL/SLA, yaive yekutanga 3D yekudhinda tekinoroji pamusika. Chuck Hull akachigadzira muna 1984, akachipa patent muna 1986, uye akatanga 3D Systems. Maitiro acho anoshandisa laser danda kuita polymerize photoactive monomer zvinhu muvat. Iwo mafotopolymerized (akaporeswa) anonamira kune ndiro yekuvaka inokwira kumusoro kana pasi zvichienderana nehardware, ichibvumira akatevedzana akaturikidzana kuti aumbe. Masisitimu eSLA anogona zvakare kugadzira zvidiki uye zvakaringana zvikamu uchishandisa diki laser beam dhayamita, mukuita inozivikanwa semicro SLA kana µSLA. Ivo vanogona zvakare kugadzira zvikamu zvakakura kwazvo vachishandisa dhayamita hombe uye nguva refu yekugadzira, mukati mekuvaka mavhoriyamu anoyera kupfuura maviri cubic metres.
Iyo SLA-1 Stereolithography (SLA) printer, yekutanga yekutengesa 3D printer, yakaunzwa ne3D Systems muna 1987.
Kune akati wandei akasiyana evat photopolymerization tekinoroji iripo nhasi. Yokutanga kubuda mushure meSLA yaiva DLP (Digital Light Processing), yakagadzirwa neTexas Instruments uye yakaunzwa kumusika muna 1987. Panzvimbo yekushandisa laser beam ye photopolymerization, teknolojia yeDLP inoshandisa digital light projector (yakafanana neyakajairwa TV projector). Izvi zvinoita kuti ikurumidze kupfuura SLA, sezvo inogona photopolymerize yose layer yechinhu kamwechete (inonzi "planar" process). Nekudaro, kunaka kwezvikamu kunoenderana nekugadziriswa kweprojekita uye kuderera sezvo saizi inowedzera.
Kufanana nezvinhu extrusion, stereolithography yakava nyore kuwanikwa nekuwanikwa kwemaitiro akaderera. Yekutanga-yakaderera masisitimu yakavakirwa pane yekutanga SLA uye DLP maitiro. Zvisinei, mumakore achangopfuura, chizvarwa chitsva che-ultra-low-cost, compact systems inobva pa LED / LCD magetsi emagetsi akabuda. Iyo inotevera shanduko yevat photopolymerization inozivikanwa se "inoenderera" kana "layerless" photopolymerization, iyo inowanzoenderana neiyo DLP dhizaini. Aya maitiro anoshandisa membrane, kazhinji okisijeni, kugonesa kukurumidza uye kuenderera kwemitengo yekugadzira. Patent yerudzi urwu rwestereolithography yakatanga kunyoreswa muna 2006 neEnvisionTEC, kambani yeDLP yave kunzi ETEC, zvichitevera kutorwa kwayo neDesktop Metal. Nekudaro, Carbon, kambani yeSilicon Valley-based, ndiyo yekutanga kutengesa tekinoroji iyi muna 2016 uye yabva yazvisimbisa semutungamiri mumusika. Carbon's tekinoroji, inozivikanwa seDLS (Dhijitari Mwenje Synthesis), inopa yakakwira zvakanyanya chiyero chekugadzira uye kugona kugadzira zvikamu zvine akasimba mahybrid zvinhu, achibatanidza thermosets uye photopolymers. Mamwe makambani, akadai se3D Systems (Mufananidzo 4), Origin (ikozvino chikamu cheStratasys), LuxCreo, Carima, nevamwe, vakaunzawo matekinoroji akafanana kumusika.
