(EN) SYSTEMS AND METHODS FOR ADDITIVE MANUFACTURE
(FR) SYSTÈMES ET PROCÉDÉS DE FABRICATION ADDITIVE
Abstract
(EN)
Disclosed are various embodiments of systems and methods of performing part build simulation for Additive Manufacture ("AM") parts applying various optimization methods in creation of three-dimensional volume quality models of AM parts during an AM build. An embodiment of the present disclosure provides a method including applying at least a fidelity model to design data for an AM part to estimate one or more AM part parameters; determining one or more part-specific AM build parameters; generating and optimizing a digital twin of the AM part; validating one or more optimization constraints and one or more materials to be used in the AM build process to achieve the one or more corresponding material properties of the AM part; updating the digital twin; verifying that the digital twin meets a geometry prescribed by the design data of the AM part; and transmitting AM part build instructions for building the AM part.

L'invention concerne divers modes de réalisation de systèmes et de procédés de réalisation d'une simulation de construction de pièces pour des pièces de fabrication additive ("FA") appliquant divers procédés d'optimisation dans la création de modèles tridimensionnels volumiques de qualité de pièces de FA pendant une construction par FA. Un mode de réalisation de la présente invention concerne un procédé consistant à appliquer au moins un modèle de fidélité pour concevoir des données pour une pièce de FA pour estimer un ou plusieurs paramètres de pièce de FA ; déterminer un ou plusieurs paramètres de construction par FA spécifiques à une pièce ; générer et optimiser un double numérique de la pièce de FA ; valider une ou plusieurs contraintes d'optimisation et un ou plusieurs matériaux à utiliser dans le processus de construction par FA pour obtenir ladite une ou lesdites plusieurs propriétés de matériau correspondantes de la pièce de FA ; mettre à jour le double numérique ; vérifier que le double numérique satisfait à une géométrie prescrite par les données de conception de la pièce de FA ; et transmettre les instructions de construction de pièce de FA pour construire la pièce de FA.
