Title
(EN) CALIBRATION FOR ADDITIVE MANUFACTURING
(FR) ÉTALONNAGE POUR LA FABRICATION ADDITIVE
Abstract
(EN) A method for additive fabrication includes determining numerical calibration transforms for calibrating an imaging sensor and a printhead assembly to a common coordinate system, where at least some of the numerical calibration transforms include nonlinear transforms.
(FR) Un procédé de fabrication additive consiste à déterminer des transformées d'étalonnage numérique pour étalonner un capteur d'imagerie et un ensemble tête d'impression par rapport à un système de coordonnées commun, au moins certaines des transformées d'étalonnage numérique comprenant des transformées non linéaires.
