Nkà na ụzụ ngwa ngwa Prototyping (RP) bụ teknụzụ nrụpụta ọhụrụ emepụtara na 1980s.N'adịghị ka ịcha omenala, RP na-eji usoro nchịkọta ihe oyi akwa-site-layer iji hazie ụdị siri ike, ya mere a na-akpọkwa ya Additive Manufacturing (AM) ma ọ bụ Layered Manufacturing Technology (LMT).Enwere ike ị nweta echiche nke RP na patent 1892 US maka usoro laminated nke imepụta ụdị eserese 3D.N'afọ 1979, Prọfesọ Wilfred Nakagawa nke Institute of Production Technology, Mahadum Tokyo, Japan, chepụtara usoro ihe nlegharị anya nke laminated, na 1980 Hideo Kodama tụpụtara usoro ihe ngosi ọkụ.N'afọ 1988, 3D Systems bụ onye mbụ malitere usoro prototyping ngwa ngwa azụmaahịa mbụ nke ụwa, SLA-1 na-akpụzi ọkụ, nke a na-ere n'ahịa ụwa na ọnụ ahịa ahịa kwa afọ nke 30% ruo 40%.
N'ichepụta ihe mgbakwunye foto nke SLA bụ usoro nrụpụta mgbakwunye nke a na-etinye laser ultraviolet (UV) na vat nke resin fotopolymer.Site n'enyemaka nke kọmpụta na-emepụta ihe, ngwanrọ na-enye aka na kọmputa (CAD/CAM), a na-eji laser UV na-esepụta ihe a na-emebu ma ọ bụ ọdịdị n'elu foto ebelatala.Ka a na-amata fotopolymer na ọkụ UV, resin na-agwọta ka ọ mepụta oyi akwa nke ihe 3D achọrọ.A na-emeghachi usoro a maka oyi akwa ọ bụla nke imewe ahụ ruo mgbe ihe 3D zuru ezu.
SLA bụ usoro obibi akwụkwọ kachasị ewu ewu n'oge a, yana usoro SLA na-ejikarị maka ibipụta resins mmetụta.Enwere ike iji usoro SLA bipụta efere aka iji nyochaa arụmọrụ na ọdịdị ya, yana ọnụ ọgụgụ anime, nke enwere ike iji dị ka mkpokọta ozugbo mgbe agbachara ya.
