Lazeri-yuzuye neza ihinduranya umurongo uciye mu cyuma, hasigara dogere 90-nziza-nziza.Urupapuro rw'icyumani inzira yingenzi mu nganda zikora, kandi ni ihindagurika rya plastike yimirimo hejuru yumurongo, itera impinduka muri geometrie.Bisa nubundi buryo bwo gukora ibyuma, kugoreka bihindura imiterere yumurimo, mugihe ingano yibikoresho izakomeza kuba imwe.Rimwe na rimwe usanga tekinoroji igoramyeirashobora kuzana impinduka ntoya mubyimbye.Kubikorwa byinshi, bizatanga mubyukuri nta gihinduka mubyimbye.Usibye gukora imiterere ya geometrike yifuzwa, kunama bikoreshwa mugutanga imbaraga no gukomera kumpapuro zicyuma, kugirango uhindure igice cyigihe cyo kutagira inertie, kubwo kwisiga no gukuraho impande zikarishye.Umusaruro wibyuma bya prototyping ibice bigizwe no gukora urupapuro rwicyuma (ibintu bigereranywa byabonetse mugukata lazeri) kugirango biguhe ishusho nuburyo bugaragara.Dukora ibikorwa bitandukanye byo gushiraho no kuzinga, gukubita, kashe no guteranya gusudira.Kurangiza bitandukanye birashobora gukoreshwa (gushushanya, gushushanya, nibindi).Gukoresha izi nzira zitandukanye biterwa nibikoresho byatoranijwe, ubunini bwurupapuro rwakoreshejwe (ukurikije ibyifuzo bya prototypes yawe cyangwa urukurikirane ruto) nuburyo bwatoranijwe.
