  • the irradiation of the area B can continue to be carried out synchronously with the heating, wherein the energy beam 21, for example during the additive construction of the component 10 by an eye (not explicitly marked) of Indukti onsspule or the heating head and / or the device 300 is performed ,
  • This can advantageously enable a synchronous movement with a working laser (cf reference numeral 21 in Figure 1 g) for the construction of the component 10.
  • an energy beam 21 during the manufacture of the device 10 during operation always by the "eye" of the induction coil L to the predetermined position in the area B on the mounting surface AF.
  • This area B is preferably the area which is heated by the heating head L anyway.
  • the invention is not limited by the description based on the embodiments of these, but includes each new feature and any combination of features. This includes in particular any combination of features in the claims, even if this feature or this combi nation itself is not explicitly stated in the claims or exemplary embodiments.

Abstract

L'invention concerne un dispositif (300) de chauffage sélectif d'un matériau de composant (P) pour la fabrication additive d'un composant (10), en particulier à base de lit de poudre. Le dispositif comprend une plateforme (200) comportant une tête chauffante (L), en particulier une tête chauffante inductive, et une suspension (201) qui soutient la plateforme (200) et qui est conçue pour déplacer la plateforme (200) de manière contrôlée le long de trois directions spatiales verticales (X, Y, Z) dans un espace de montage (AR) d'une installation de fabrication additive (100). L'invention concerne en outre une installation de fabrication additive (100) comprenant le dispositif (300) et un procédé de fabrication additive correspondant.
