Abstract

L'invention concerne un dispositif de génération de rayonnement, un dispositif de fabrication additive et un procédé de fabrication additive, le dispositif de génération de rayonnement comprenant : une cathode pouvant permettre l'échappement d'électrons après avoir été chauffée ; un dispositif laser conçu pour générer un laser afin de chauffer la cathode ; une grille conçue pour faire converger les électrons afin de former un faisceau d'électrons ; et une anode disposée sous la cathode et reliée à la terre, un trou étant formé au milieu de l'anode, et une différence de potentiel pour permettre au faisceau d'électrons de passer par le trou formé entre l'anode et la cathode.
