Sabuwar fasahar da masana kimiyyar Switzerland suka kirkira na iya inganta tsarin bugu na 3D na gilashi

Daga cikin duk kayan da za a iya buga 3D, gilashin har yanzu yana daya daga cikin mafi kalubale.Koyaya, masana kimiyya a Cibiyar Bincike na Cibiyar Fasaha ta Tarayya ta Switzerland Zurich (ETH Zurich) suna aiki don canza wannan yanayin ta hanyar sabuwar fasahar buga gilashin.

Yanzu yana yiwuwa a buga abubuwan gilashi, kuma hanyoyin da aka fi amfani da su sun haɗa da ko dai fitar da narkakkar gilashin ko kuma zaɓen yumbu foda (laser dumama) don canza shi zuwa gilashi.Na farko yana buƙatar yanayin zafi mai zafi don haka kayan aiki masu jurewa zafi, yayin da na ƙarshe ba zai iya samar da abubuwa masu rikitarwa musamman ba.Sabuwar fasahar ETH tana da nufin inganta waɗannan gazawar guda biyu.
