DMLS, Bugun 3D na Abubuwan ƙarfe
DMLS fasaha ce mai matukar haɓaka masana'antu wacce uyana amfani da karafan da aka zana a matsayin tushe. Yana amfani da Laser mai ƙarfi don haɗuwa kuna zaba barbashi ƙarfe. Anyi wannan Layer da Layer, tare da injin yana rarraba sabon rufin ƙarfe na ƙarfe bayan an saƙa ɗaya tak. Yana da mahimmanci a sanya hankali ana iya buƙatar tsarin tallafi. Koyaya, waɗannan abubuwan an ƙirƙira su ta atomatik kuma daga baya za a cire da hannu. Da zarar an gama bugawa, za'ayi maganin zafi na karshe.
