Stereolithography (SLA) ndiyo inonyanya kushandiswa nekukurumidza prototyping tekinoroji. Inogona kuburitsa yakanyatso uye yakadzama polymer zvikamu. Yakanga iri yekutanga yekukurumidza prototyping process, yakaunzwa muna 1988 ne3D Systems, Inc., zvichibva pabasa nemugadziri Charles Hull. Inoshandisa yakaderera-simba, yakanyanya kutariswa UV laser kuteedzera inotevedzana-zvikamu zvechimwe-mativi matatu-dimensional chinhu muvhati yemvura photosensitive polymer. Sezvo iyo laser inoteedzera layer, iyo polymer inoomesa uye nzvimbo dzakawandisa dzinosara semvura. Kana chitubu chapedzwa, blade yekuyera inofambiswa nepamusoro pepamusoro kuti itsvedzerere isati yaisa imwe inotevera. Iyo puratifomu inodzikiswa nechinhambwe chakaenzana nehupamhi hwemachira (kazhinji 0.003-0.002 mukati), uye chinotevera chigadziko chinoumbwa pamusoro peakapedzwa kare. Iyi nzira yekutsvaga uye kutsetseka inodzokororwa kusvikira kuvaka kwapera. Kana yapera, chikamu chacho chinokwidziridzwa pamusoro pevheti uye chinodonhedzwa. Yakawandisa polymer inogezwa kana kusukwa kubva panzvimbo. Muzviitiko zvakawanda, mushonga wekupedzisira unopiwa nekuisa chikamu muvheni yeUV. Mushure mekurapa kwekupedzisira, zvitsigiso zvinogurwa chikamu uye nzvimbo dzinokwenenzverwa, kuchekwa kana kupedzwa neimwe nzira.
