Abstract

La présente invention concerne un procédé de fabrication additive sélective d’un objet tridimensionnel à partir d’une couche de poudre, le procédé comprenant les étapes de : application d’une couche de poudre de fabrication additive sur un support ou sur une couche préalablement consolidée, émission d’un faisceau laser sur un premier point de la couche de poudre de fabrication additive, de sorte à consolider une première zone de la couche de poudre comprenant le premier point, le procédé comprenant en outre un ajustement d’une vitesse de balayage du faisceau laser en fonction d’une variation de température estimée de la couche de poudre en un deuxième point distinct du premier point de la couche de poudre causée par l’émission du faisceau laser de sorte à consolider la première zone de la couche de poudre, une émission d’un faisceau laser sur le deuxième point de sorte à consolider une deuxième zone de la couche de poudre comprenant le deuxième point, la variation de température estimée étant fonction d’un intervalle de temps prédéterminé séparant l’émission sur le premier point et l’émission sur le deuxième point et de la distance séparant le premier point et le deuxième point qui est égale au produit de la vitesse de balayage ajustée par l’intervalle de temps prédéterminé.
