Zusammenfassung:	An additive manufacturing apparatus for forming an object includes a platen to support the object being formed, a dispenser to deliver a plurality of layers of a powder to the platen, an inductive heater configured to generate eddy currents in a region of the powder, and an energy source to apply energy to the powder to form a fused portion of the powder. Un appareil de fabrication additive pour former un objet comprend un plateau pour supporter l'objet formé, un distributeur pour distribuer une pluralité de couches d'une poudre au plateau, un dispositif de chauffage inductif configuré pour générer des courants de foucault dans une région de la poudre, et une source d'énergie pour appliquer de l'énergie à la poudre pour former une partie fondue de la poudre.
