Ib pab neeg tshawb fawb ntawm lub tsev kawm ntawv ntawm twente nyob rau hauv Netherlands tau tsim ib txoj kev ntawm 3D luam ntawv ntawm cov hlau microstructures ua los ntawm cov khoom kub .Cov txheej txheem pioneered los ntawm pab pawg neeg siv laser technology los tso nyiaj me me hlau poob rau daim qauv.
Txoj kev piav qhia nyob rau hauv ib tsab xov xwm nyuam qhuav luam tawm nyob rau hauv phau ntawv hu ua Additive Manufacturing thiab hu ua "laser-induced forward transfer" lossis LIFT. Hauv kev qhia ntau ntxiv, cov txheej txheem yuav tsum muaj melting me me ntawm cov hlau ntawm lo lus nug los ntawm firing ultrashort laser mem tes mus rau ib zaj duab xis hlau (peb nyob nraum tham txog tus dav nanometer). Qhov dej tshuaj no yog "tawm mus" rau nws lub hom phiaj thiab ua kom tiav thaum nws thaj av.
Muaj qee cov kev cov nyom hauv kev tsim txoj kev txhawb nqa. Piv txwv, cov neeg soj ntsuam txhawj tias ob co hlau yuav sib tov rau hauv qhov nruab nrab tom qab raug txau, uas yuav cuam tshuam qhov kawg ntawm cov qauv 3D. Kuj zoo, tus txheej txheem tsim tsis kom haum.Raws li ntawm pab pawg neeg cov ntsiab lus tawm, qhov teeb meem ntawm qhov teeb meem ntawm 0.3 thiab 0.7 microns li qhov luaj li cas ntawm cov hlau plhaws tsuas yog ob peb ya liters (li 10-15 litres).
