Cov Khoom Siv Hlau

Cov lus piav qhia luv luv:

Cov hmoov hlau yog cov hlau uas raug txo kom qhov zoo thiab yog cov khoom siv ua ntej rau feem ntau 3D luam ntawv cov txheej txheem uas ua cov khoom siv hlau. 3D tshuab luam ntawv, tseem hu ua additive manufacturing (AM), yog kev tsim khoom ntawm qhov chaw thiab cov khoom lag luam hauv txheej txheej los ntawm txheej kev zam. Ob qho yam ntxwv ntawm cov hlau hmoov thiab hom 3D txheej txheem luam tawm txiav txim cov yam ntxwv ntawm cov khoom kawg. Hmoov cov cim yuav siv qhov chaw nyob ntawm nws txoj kev tsim tawm, uas yuav ua rau muaj qhov sib txawv ntawm cov qauv morphology thiab purity.
