Zusammenfassung:	A processing machine (10) for building an object (11) from powder particles (12) includes a build platform (26), an excitation system (21) and an electron beam irradiation device (22). The build platform (26) includes a support surface (26B) that supports the powder particles (12). The excitation system (21) directs an excitation light (21B) at a plurality of the powder particles (12). The electron beam irradiation device (22) irradiates the plurality of the powder particles (12) with an electron beam (22D). Selon la présente invention, une machine de traitement (10) destinée à construire un objet (11) à partir de particules de poudre (12) comprend une plateforme de construction (26), un système d'excitation (21) et un dispositif d'exposition à un faisceau d'électrons (22). La plateforme de construction (26) comprend une surface de soutien (26B) qui soutient les particules de poudre (12). Le système d'excitation (21) dirige une lumière d'excitation (21B) vers une pluralité de particules de poudre (12). Le dispositif d'exposition à un faisceau d'électrons (22) expose la pluralité des particules de poudre (12) à un faisceau d'électrons (22D).
