Ntawm tag nrho cov ntaub ntawv uas tuaj yeem ua 3D luam tawm, iav tseem yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws.Txawm li cas los xij, cov kws tshawb fawb ntawm Lub Chaw Tshawb Fawb ntawm Swiss Federal Institute of Technology Zurich (ETH Zurich) tab tom ua haujlwm los hloov qhov xwm txheej no los ntawm kev siv tshuab luam ntawv iav tshiab thiab zoo dua.
Tam sim no nws muaj peev xwm luam tawm cov khoom iav, thiab cov kev siv feem ntau muaj xws li extruding molten iav los yog xaiv sintering (laser cua sov) ceramic hmoov los hloov nws mus rau hauv iav.Cov qub yuav tsum tau kub siab thiab yog li cov khoom siv hluav taws xob tiv taus, thaum tom kawg tsis tuaj yeem tsim cov khoom tshwj xeeb.ETH cov thev naus laus zis tshiab txhawm rau txhim kho ob qhov tsis zoo no.
Nws muaj cov photosensitive resin uas muaj li ntawm cov kua yas thiab cov organic molecules sib koom ua ke rau silicon-muaj cov molecules, nyob rau hauv lwm yam lus, lawv yog ceramic molecules.Siv cov txheej txheem uas twb muaj lawm hu ua digital light processing, cov resin raug rau cov qauv ntawm lub teeb ultraviolet.Tsis muaj teeb meem qhov twg lub teeb hits cov resin, cov yas monomer yuav hla-txuas mus rau ib qho khoom polymer.Cov polymer muaj cov qauv zoo li labyrinth sab hauv, thiab qhov chaw hauv lub labyrinth tau ntim nrog cov khoom siv ceramic.
Tom qab ntawd cov khoom peb-dimensional tau raug rho tawm haujlwm ntawm qhov kub ntawm 600 ° C kom hlawv tawm cov polymer, tsuas yog cov ceramic.Hauv kev tua hluav taws thib ob, qhov hluav taws kub kub yog li 1000 ° C, thiab cov ceramic yog densified rau hauv pob tshab iav porous.Cov khoom lag luam poob qis thaum nws hloov mus rau hauv iav, uas yog qhov tseem ceeb uas yuav tsum tau xav txog hauv cov txheej txheem tsim.
Cov kws tshawb fawb tau hais tias txawm hais tias cov khoom tsim los txog tam sim no me me, lawv cov duab yog qhov nyuaj heev.Tsis tas li ntawd, qhov pore loj tuaj yeem hloov kho los ntawm kev hloov qhov siv ntawm ultraviolet rays, lossis lwm yam khoom ntawm lub khob tuaj yeem hloov pauv los ntawm kev sib xyaw borate lossis phosphate rau hauv cov resin.
Ib tug loj Swiss glassware distributor twb tau nthuav tawm kev txaus siab rau kev siv thev naus laus zis, uas zoo ib yam li cov cuab yeej tsim los ntawm Karlsruhe Institute of Technology hauv lub teb chaws Yelemees.
