Title
(EN) METHOD AND SYSTEM FOR CONTROLLING A COOLING SYSTEM IN THREE-DIMENSIONAL PRINTING
(FR) PROCÉDÉ ET SYSTÈME DE COMMANDE D'UN SYSTÈME DE REFROIDISSEMENT DANS UNE IMPRESSION TRIDIMENSIONNELLE
Abstract
(EN)
A method of additive manufacturing, comprises: dispensing from an array of nozzles an amount of building material formulation to form a layer in a configured pattern corresponding to a shape of a slice of an object, and hardening the layer. Based on the amount and a geometrical characteristic of the slice, a thermal mass of the layer is calculated. A cooling system is controlled in a closed loop control responsively to the calculated thermal mass.
(FR)
Un procédé de fabrication additive comprend : la distribution à partir d'un réseau de buses d'une quantité de formulation de matériau de construction pour former une couche dans un motif configuré correspondant à une forme d'une tranche d'un objet, et le durcissement de la couche. Sur la base de la quantité et d'une caractéristique géométrique de la tranche, une masse thermique de la couche est calculée. Un système de refroidissement est commandé dans une commande en boucle fermée en réponse à la masse thermique calculée
