I-Stereolithography (SLA) yeyona teknoloji ye-proteyipt esetyenziswe ngokukhawuleza. Ingavelisa iinxalenye ezichanileyo nezineenkcukacha. It was the first rapid prototyping process, introduced in 1988 by 3D Systems, Inc., based on work by inventor Charles Hull. It uses a low-power, highly focused UV laser to trace out successive cross-sections of a three-dimensional object in a vat of liquid photosensitive polymer. Njengoko i-laser ilandela ungqimba, ipolymer iqinisa kwaye iindawo ezigqithisileyo zishiywe njengolwelo. Xa kugqityiwe ukugqitywa, i-blade yenqanaba ifudukele kumphezulu ukuba igudise ngaphambi kokuba ifake umaleko olandelayo. Iqonga lehlisiwe ngumgama olingana nobungqingqwa (ngokwesiqhelo i-0.003-0.002 kwi), kwaye umaleko olandelayo usenziwe ngaphezulu kwezona zingqinisiso zigqityiweyo. Le nkqubo yokulandela umkhondo kunye nokuthandwayo kukuphindwa de kufike ulwakhiwo. Xa sele ugqibile, inxenye iphakanyisiwe ngaphezulu kwe-VAT kwaye ikhutshiwe. I-polymer ethe kratya ibhujiswa okanye ikhutshiwe kude kumphezulu. Kwiimeko ezininzi, unyango lokugqibela lunikezelwa ngokubeka inxaxheba kwi-oveni ye-UV. Emva konyango lokugqibela, ukuxhasa kunqunyulwa inxenye kwaye umphezulu ucinyiwe, ukhwele okanye ugqibile ngenye indlela.
