Abstract

L’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 puissance 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, la variation de température estimée étant fonction de la distance entre le premier point et le deuxième point et d’un intervalle de temps prédéterminé, une émission d’un faisceau laser sur le deuxième point avec la puissance ajustée de sorte à consolider une deuxième zone de la couche de poudre comprenant le deuxième point, l’émission du faisceau laser sur le premier point et l’émission du faisceau laser sur le deuxième point étant temporellement séparées de l’intervalle de temps prédéterminé.
