Phakathi kwazo zonke izinto ezinokuprintwa nge-3D, iglasi iseyeyona nto inzima kakhulu.Nangona kunjalo, izazinzulu kwiZiko loPhando le-Swiss Federal Institute of Technology Zurich (ETH Zurich) basebenzela ukutshintsha le meko ngokusebenzisa iteknoloji entsha yokushicilela iglasi.
Ngoku kuyenzeka ukuba ushicilele izinto zeglasi, kwaye ezona ndlela zixhaphakileyo zisetyenziswa zibandakanya ukukhupha iglasi etyhidiweyo okanye ngokukhetha i-sintering (i-laser yokufudumeza) umgubo weceramic ukuyiguqulela kwiglasi.Eyangaphambili ifuna amaqondo obushushu aphezulu kwaye ngoko ke izixhobo ezikwazi ukumelana nobushushu, ngelixa ezi zamva azikwazi ukuvelisa izinto ezintsonkothileyo.Itekhnoloji entsha ye-ETH ijolise ekuphuculeni ezi ntsilelo zimbini.
Iqulethe i-resin ye-photosensitive eyenziwe ngeplastiki yolwelo kunye neemolekyuli ze-organic ezidityaniswe kwiimolekyuli ezine-silicon, ngamanye amagama, ziyi-molecule ze-ceramic.Ukusebenzisa inkqubo ekhoyo ebizwa ngokuba yi-digital light processing, i-resin ibonakaliswe kwipatheni yokukhanya kwe-ultraviolet.Kungakhathaliseki ukuba ukukhanya kubetha i-resin, i-monomer yeplastiki iya kunqumla ikhonkco ukwenza i-polymer eqinile.I-polymer inesakhiwo sangaphakathi esifana ne-labyrinth, kwaye indawo kwi-labyrinth igcwele iamolekyu ze-ceramic.
Isiphumo se-dimensional-three-dimensional into ke igxothwe kwiqondo lokushisa lama-600 ° C ukutshisa i-polymer, ishiya i-ceramic kuphela.Ngokudubula okwesibini, ukushisa kokudubula ku malunga ne-1000 ° C, kwaye i-ceramic igxininiswe kwiglasi ye-porous ebonakalayo.Into iyancipha kakhulu xa iguqulwa ibe yiglasi, into ekufuneka ithathelwe ingqalelo kwinkqubo yoyilo.
Abaphandi bathi nangona izinto ezenziweyo ukuza kuthi ga ngoku zincinci, imilo yazo inzima kakhulu.Ukongezelela, ubukhulu bepore bunokutshintshwa ngokutshintsha ubuninzi bemisebe ye-ultraviolet, okanye ezinye iimpawu zeglasi zingatshintshwa ngokuxuba i-borate okanye i-phosphate kwi-resin.
Umsasazi omkhulu we-glassware waseSwitzerland sele ebonakalise umdla wokusebenzisa itekhnoloji, efana nobuchwepheshe obuphuhliswa kwiKarlsruhe Institute of Technology eJamani.
