Ukadaulo watsopano wopangidwa ndi asayansi aku Swiss ukhoza kukonza njira yosindikizira ya 3D yagalasi

Pakati pa zipangizo zonse zomwe zingathe kusindikizidwa 3D, galasi akadali chimodzi mwa zipangizo zovuta kwambiri. Komabe, asayansi ku Research Center ya Swiss Federal Institute of Technology Zurich (ETH Zurich) akuyesetsa kusintha izi kudzera muukadaulo watsopano komanso wabwinoko wosindikiza magalasi.

Tsopano ndizotheka kusindikiza zinthu zamagalasi, ndipo njira zomwe zimagwiritsidwa ntchito kwambiri zimaphatikizapo kutulutsa magalasi osungunuka kapena kusankha sintering (kutentha kwa laser) ufa wa ceramic kuti ukhale galasi. Zakale zimafuna kutentha kwakukulu kotero kuti zipangizo zosagwira kutentha, pamene zotsirizirazi sizingathe kupanga zinthu zovuta kwambiri. Tekinoloje yatsopano ya ETH ikufuna kukonza zolakwika ziwirizi.

Lili ndi utomoni wa photosensitive wopangidwa ndi pulasitiki yamadzimadzi ndi mamolekyu achilengedwe omangika ku mamolekyu okhala ndi silicon, mwa kuyankhula kwina, ndi mamolekyu a ceramic. Pogwiritsa ntchito njira yomwe ilipo kale yotchedwa digital light processing, utomoni umakhala ndi mawonekedwe a kuwala kwa ultraviolet. Ziribe kanthu komwe kuwala kugunda utomoni, pulasitiki monomer imadutsa ulalo kuti ipange polima wolimba. Polima ili ndi mawonekedwe amkati ngati labyrinth, ndipo malo mu labyrinth amadzaza ndi mamolekyu a ceramic.

Chotsatira cha mbali zitatuzi chimawotchedwa pa kutentha kwa 600 ° C kuti chiwotche polima, ndikusiya ceramic yokha. Pakuwombera kwachiwiri, kutentha kwa kuwombera kumakhala pafupifupi 1000 ° C, ndipo ceramic imayikidwa mu galasi lowoneka bwino. Chinthucho chimachepa kwambiri pamene chisinthidwa kukhala galasi, chomwe ndi chinthu chomwe chiyenera kuganiziridwa popanga mapangidwe.

Ofufuzawa adanena kuti ngakhale zinthu zomwe zidapangidwa mpaka pano ndi zazing'ono, mawonekedwe ake ndi ovuta kwambiri. Kuphatikiza apo, kukula kwa pore kumatha kusinthidwa posintha mphamvu ya kuwala kwa ultraviolet, kapena zinthu zina zagalasi zitha kusinthidwa ndikusakaniza borate kapena phosphate mu utomoni.

Wofalitsa wamkulu wa glassware wa ku Switzerland wasonyeza kale chidwi chogwiritsa ntchito lusoli, lomwe liri lofanana ndi luso lomwe likupangidwa ku Karlsruhe Institute of Technology ku Germany.
