Nyob rau hauv ib daim ntawv hu ua " 3D printing dielectric ceramic tsis muaj sintering theem ," ib pab neeg tshawb fawb tau piav li cas lawv tsim dielectric ceramic qhov chaw siv 3D printing thaum bypassing feem ntau tsim nyog sintering theem.Conventional sintering, lawv piav qhia, yuav siv sij hawm thiab lub zog.Tau li, ceramic hmoov muaj compressed nrog cov organic additives thiab ces hlawv thiab sintered ntawm kev kub muaj peev xwm.Qhov tshwm sim ntawm txoj kev no yog tias cov hmoov compacts rau khoom nplov vim thermally pab pawg thauj. Lub sijhawm thiab lub zog uas siv los ntawm qhov txheej txheem yog tsuas yog ib qho ntawm cov kev poobsiab - nws tseem nyuaj rau kev tswjhwm, uas txhais tau tias yuav tau rov ua dua ntxiv ntawm qhov yuav tsum tau.
Hmoov txoov yaj tsuas yog ib txoj hauv kev ua khoom ntawm cov khoom ua kom siv ziab. Hauv daim ntawv no, cov soj ntsuam ntawm tsom rau cov ntaub ntawv extrusion.They mixed dej-soluble lithium molybdate (Li2MoO4) nrog dej ua 3D printing paste.
Thaum sib xyaw xim zoo li ntawm cov khoom siv zom dawb thiab cov dej ntub dej, cov qauv phaj yog 3D luam tawm uas siv cov tshuab luam yeeb tsawg tsawg tus syringe 3D.Qhov npoo ntawm tus qauv yog tus zoo, zoo tshaj plusion, zoo shear. Lub microstructure, qhov ceev thiab dielectric cov khoom ntawm cov ntawv luam tawm yog tshawb xyuas qhov sib tw. Cov dej sib tov muaj li dej tsawg tau kom tsis txhob porosity, as Well as cracking thiab shrinkage, uas tau tshwm sim thaum lub sij hawm ntev qhuav.
