Phakathi kwazo zonke izinto ezingase ziphrintwe nge-3D, ingilazi isengenye yezinto eziyinselele kakhulu. Nokho, ososayensi eSikhungweni Sokucwaninga seSwiss Federal Institute of Technology Zurich (ETH Zurich) basebenzela ukuguqula lesi simo ngobuchwepheshe obusha nobungcono bokunyathelisa ingilazi.
Manje sekungenzeka ukuphrinta izinto zengilazi, futhi izindlela ezisetshenziswa kakhulu zibandakanya ukukhipha ingilazi encibilikisiwe noma i-sintering ekhethiwe (i-laser heat) i-ceramic powder ukuyiguqula ibe ingilazi. Okwangaphambili kudinga izinga lokushisa eliphezulu ngakho-ke imishini ekwazi ukumelana nokushisa, kuyilapho leyamuva ingakwazi ukukhiqiza izinto eziyinkimbinkimbi ngokukhethekile. Ubuchwepheshe obusha be-ETH buhlose ukuthuthukisa lezi ziphutha ezimbili.
Iqukethe inhlaka ye-photosensitive eyakhiwe ngepulasitiki ewuketshezi kanye nama-molecule e-organic ahlanganiswe nama-molecule aqukethe i-silicon, ngamanye amazwi, ama-molecule e-ceramic. Kusetshenziswa inqubo ekhona ebizwa ngokuthi ukucutshungulwa kokukhanya kwedijithali, i-resin ivezwa iphethini yokukhanya kwe-ultraviolet. Noma ngabe ukukhanya kushaya kuphi i-resin, i-monomer yepulasitiki izoxhumanisa ukuze yakhe i-polymer eqinile. I-polymer inesakhiwo sangaphakathi esifana ne-labyrinth, futhi isikhala ku-labyrinth sigcwele ama-molecule e-ceramic.
Into engumphumela we-three-dimensional ibe isishiswa kumazinga okushisa angu-600°C ukuze kushiswe i-polymer, kusale i-ceramic kuphela. Ekudubuleni kwesibili, izinga lokushisa lokudubula lingaba ngu-1000 ° C, futhi i-ceramic ihlanganiswa ibe ingilazi ye-porous ekhanyayo. Into iyancipha kakhulu uma iguqulwa ibe ingilazi, okuyisici okufanele sicatshangelwe enqubweni yokuklama.
Abacwaningi bathi nakuba izinto ezidaliwe kuze kube manje zincane, izimo zazo ziyinkimbinkimbi. Ngaphezu kwalokho, ubukhulu bembotshana bungalungiswa ngokushintsha ukushuba kwemisebe ye-ultraviolet, noma ezinye izakhiwo zengilazi zingashintshwa ngokuxuba i-borate noma i-phosphate ku-resin.
Umsabalalisi omkhulu we-glassware wase-Swiss usevele uzwakalise intshisekelo yokusebenzisa lobu buchwepheshe, obufana nobuchwepheshe obuthuthukiswa e-Karlsruhe Institute of Technology eJalimane.
