Ibyo ukeneye byose kumenya ibyahise, ibya none nibizaza bya stereolithography

Vat Photopolymerisation, cyane cyane laser stereolithography cyangwa SL / SLA, niyo tekinoroji ya mbere yo gucapa 3D ku isoko. Chuck Hull yahimbye mu 1984, ayitanga mu 1986, ashinga 3D Sisitemu. Inzira ikoresha urumuri rwa laser kugirango polymerize ibikoresho bifotora monomer muri vatiri. Fotopolymerized (yakize) ibice byubahiriza isahani yubaka izamuka hejuru cyangwa hepfo bitewe nicyuma, bigatuma ibice bikurikirana bikora. Sisitemu ya SLA irashobora kandi kubyara ibice bito cyane kandi byuzuye ukoresheje diameter ntoya ya laser, murwego ruzwi nka micro SLA cyangwa µSLA. Barashobora kandi kubyara ibice binini cyane bakoresheje diameter nini nini nigihe kinini cyo kubyara, mububiko bwububiko bupima metero kibe ebyiri.

Icapa rya SLA-1 Stereolithography (SLA), icapiro rya mbere ryubucuruzi rya 3D, ryatangijwe na 3D Systems mu 1987.

Hariho uburyo bwinshi bwa tekinoroji ya fotopolymerisation iboneka uyumunsi. Uwa mbere wagaragaye nyuma ya SLA yari DLP (Digital Light Processing), yakozwe na Texas Instruments ikazanwa ku isoko mu 1987. Aho gukoresha urumuri rwa lazeri mu gufotora, tekinoroji ya DLP ikoresha umushinga w’urumuri rwa digitale (bisa na porogaramu isanzwe ya TV). Ibi bituma byihuta kuruta SLA, kuko ishobora gufotora igice cyose cyikintu icyarimwe (byitwa inzira "planar"). Nyamara, ubwiza bwibice biterwa nigisubizo cyumushinga kandi ugabanuka uko ubunini bwiyongera.

Kimwe no gukuramo ibikoresho, stereolithography yarushijeho kuboneka hamwe na sisitemu ihendutse. Sisitemu yambere ihendutse yari ishingiye kubikorwa byumwimerere SLA na DLP. Ariko, mumyaka yashize, havutse igisekuru gishya cya ultra-giciro gito, sisitemu yoroheje ishingiye kumasoko ya LED / LCD. Ubwihindurize bukurikira bwa vat Photopolymerisation izwi nka "gukomeza" cyangwa "layerless" Photopolymerisation, ubusanzwe ishingiye kububiko bwa DLP. Izi nzira zikoresha membrane, mubisanzwe ogisijeni, kugirango igabanye umuvuduko wihuse kandi uhoraho. Ipatanti y'ubu bwoko bwa stereolithography yanditswe bwa mbere mu 2006 na EnvisionTEC, isosiyete DLP kuva icyo gihe yiswe ETEC, nyuma yo kugurwa na Desktop Metal. Nyamara, Carbon, isosiyete ikorera mu kibaya cya Silicon, niyo yabaye iyambere ku isoko ry’ikoranabuhanga mu 2016 kandi kuva ubwo yigaragaje nk'umuyobozi ku isoko. Ikoranabuhanga rya Carbone, rizwi nka DLS (Digital Light Synthesis), ritanga umusaruro mwinshi cyane hamwe nubushobozi bwo gukora ibice hamwe nibikoresho biramba bivangavanze, bihuza thermosets na Photopolymers. Andi masosiyete, nka sisitemu ya 3D (Isanamu 4), Inkomoko (ubu ni igice cya Stratasys), LuxCreo, Carima, nandi, nayo yazanye ikoranabuhanga risa ku isoko.
