Cov pob zeb uas tsis muaj pob zeb uas tsis tau muab sau cia yuav tsis yooj yim.
Nyob rau hauv ib daim ntawv luam tawm ntxov ua ntej lub lim tiam, ib pab neeg tshawb fawb tau hais tias lawv nrhiav tau ib txoj kev los tshawb cov khoom 3D-luam tawm rov qab rau cov ntawv luam tawm 3D uas ua rau lawv. Pab pawg neeg lub npe ntawm tus kheej, dubbed "PrinTracker," siv cov qauv nyob rau ntawm 3d qhov khoom tawm los txheeb xyuas lub tshuab luam ntawv uas tsim cov khoom.
Raws li lawv txoj kev tshawb fawb, Xu pawg neeg pom tau hais tias 20 xyoo dhau los ntawm Tsoom Fwv Teb Chaws Qhov Chaw Xyuas Kev Tshawb Fawb Tseg tau saib cov ntawv ntiv tes - paub cov qauv ntawm daim ntawv - kom paub cov ntaub ntawv fake. Qhov kev tshoov siab Xu thiab nws pab neeg siv tib lub tswv yim rau kev cais 3D printers.
Txoj kev tshawb no raws li kev kho vajtse sib txawv ntawm txhua lub tshuab luam ntawv uas tsim cov qauv zoo ib yam li cov yeeb yuj ntawm cov khoom luam los ntawm lub tshuab luam ntawv. Txawm tias txawv units ntawm tib yam kev ua thiab qauv ntawm kev luam ntawv yuav tsis ua raws nraim tib txoj kev, Xu hais tias, txhua qhov tawm nws cov cim discrete ntawm nws cov luam tawm.
Ntxiv rau kev soj xyuas cov phom 3d-printed, PrinTracker tuaj yeem siv los teev cov khoom cuav uas ua los ntawm 3D printers.
