Phakathi kwazo zonke izinto ezingenziwa nge-3D eziphrintiwe, ingilazi isengenye yezinto eziyinselele kakhulu. Kodwa-ke, ososayensi esikhungweni sokucwaninga seSwitzerland Federal Institute of Technology Zurich (Eth Zurich) basebenzela ukuguqula lesi simo nge-New and Better Prance Technology.
Manje kungenzeka ukuphrinta izinto ze-Glass, kanye nezindlela ezisetshenziswa kakhulu ezibandakanya ingilazi ehlukahlukene ekhishwe noma ngesono (i-laser heating) ceramic powder ukuze uyiguqulele ingilazi. Lowo owayengukuqala udinga amazinga okushisa aphezulu ngakho-ke imishini engamelana ukushisa, kanti owokugcina ayikwazi ukukhiqiza izinto eziyinkimbinkimbi. Ubuchwepheshe obusha be-Eth
Inama-resin ahlelwayo ahlanganiswe ama-molecule epulasitiki awuketshezi kanye nama-arganic molecule ahlanganiswe kuma-molecule aqukethe ama-silicon, ngamanye amagama, angama-molecule angama-ceramic. Kusetshenziswa inqubo ekhona ebizwa ngokuthi ukucubungula okukhanyayo kwedijithali, i-resin ivezwa ngephethini yokukhanya kwe-ultraviolet. Akunandaba ukuthi ukukhanya kushaya kuphi i-resin, i-monomer yepulasitiki izowela-isixhumanisi sokwakha i-polymer eqinile. I-polymer inesakhiwo sangaphakathi se-labyrinth-esinjenge-labyrinth igcwele ama-molecule ceramic.
Into ephumayo enezinhlangothi ezintathu idonswa emazingeni okushisa angama-600 ° C ukuwashisa i-polymer, ishiye kuphela ubumba. Ekudubuleni kwesibili, izinga lokushisa lokudubula licishe libe ngu-1000 ° C, futhi i-ceramic ifakwe kwingilazi esobala ye-porous. Into iyancipha kakhulu lapho iguqulwa ibe yingilazi, okuyisici okufanele kubhekwe kwinqubo yokuqamba.
Abaphenyi bathi yize izinto ezidaliwe kuze kube manje zincane, amajamo abo ayinkimbinkimbi impela. Ngaphezu kwalokho, usayizi we-pore ungashintshwa ngokushintsha ubukhulu bemisebe ye-ultraviolet, noma ezinye izakhiwo zengilazi zingashintshwa ngokuxubana noma i-phosphate ku-resin.
Umhambisi omkhulu we-swasmiss Glaswing we-Switland usevele waveza isithakazelo ekusebenziseni ubuchwepheshe, okufana nalokhu okufana nalobuchwepheshe obuthuthukiswe eKarlsruhe Institute of Technology.
