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.
Yana ƙunshe da guduro mai ɗaukar hoto wanda ya ƙunshi robobi na ruwa da ƙwayoyin halitta waɗanda ke haɗe da ƙwayoyin da ke ɗauke da silicon, a wasu kalmomi, ƙwayoyin yumbu ne. Yin amfani da tsarin da ake da shi da ake kira sarrafa hasken dijital, resin yana fallasa zuwa yanayin hasken ultraviolet. Duk inda hasken ya taɓa guduro, monomer ɗin filastik zai haye hanyar haɗin gwiwa don samar da ingantaccen polymer. Polymer yana da tsarin ciki kamar labyrinth, kuma sararin samaniya a cikin labyrinth yana cike da kwayoyin yumbura.
Sakamakon abu mai girma uku yana harba a zazzabi na 600 ° C don ƙone polymer, ya bar yumbura kawai. A cikin harbe-harbe na biyu, zafin wuta yana kusan 1000 ° C, kuma yumbu yana cike da gilashin da ba a iya gani ba. Abun yana raguwa sosai lokacin da aka canza shi zuwa gilashi, wanda shine al'amari wanda dole ne a yi la'akari da shi a cikin tsarin ƙira.
Masu binciken sun ce duk da cewa abubuwan da aka kirkira zuwa yanzu kanana ne, amma siffofinsu na da sarkakiya. Bugu da ƙari, ana iya daidaita girman pore ta hanyar canza ƙarfin hasken ultraviolet, ko wasu kaddarorin gilashin za a iya canza su ta hanyar hada borate ko phosphate a cikin guduro.
Tuni dai wani babban mai raba kayan gilasai na Swiss ya nuna sha'awar yin amfani da wannan fasahar, wacce ta dan yi kama da fasahar da ake kerawa a Cibiyar Fasaha ta Karlsruhe da ke Jamus.
