Abstract
(DE) Verfahren (100) zur Erstellung eines Fertigungsplans (4) für die additive Fertigung eines Objekts (1) mittels 3D-Druck mit den Schritten: • es wird ein dreidimensionales Modell (2) des herzustellenden Objekts (1) bereitgestellt (110); • für mindestens einen vorgegebenen Bereich (1a) des Objekts (1) wird eine mechanische Beanspruchung (3) mit einer Kraft und/oder einem Moment vorgegeben (120), der dieser Bereich (1a) standzuhalten hat; • für mindestens einen Kandidaten-Fertigungsplan (4*) wird anhand einer Simulation geprüft (130), ob nach Fertigung des Objekts (1) anhand des Kandidaten-Fertigungsplans (4*) der vorgegebene Bereich (1a) der vorgegebenen Beanspruchung (3) standhält, wobei dieser Kandidaten-Fertigungsplan (4*) vorgibt, an welchem Ort, und/oder an welcher Zeit, welches Material unter welchen Prozessparametern dem Objekt (1) zugegeben wird; • in Antwort darauf, dass der Bereich (1a) der vorgegebenen Beanspruchung (3) nicht standhält, wird der Kandidaten-Fertigungsplan (4*) verändert (140) mit dem Ziel, die Belastbarkeit des vorgegebenen Bereichs (1a) zu verbessern.
(EN) The invention relates to a method (100) for producing a manufacturing plan (4) for additively manufacturing an object (1) by means of 3D printing, said method comprising the steps: • a three-dimensional model (2) of the object (1) to be manufactured is provided (110); • for at least one predefined region (1a) of the object (1), a mechanical stress (3) is specified (120) with a force and/or a moment which this region (1a) must withstand; • for at least one candidate manufacturing plan (4*), a simulation is used to check (130) whether the predefined region (1a) withstands the predefined stress (3) after the object (1) has been manufactured on the basis of the candidate manufacturing plan (4*), wherein this candidate manufacturing plan (4*) specifies the material which is added to the object (1), the location and/or time at which said material is added, and the process parameters under which said material is added; • in response to the region (1a) not withstanding the predefined stress (3), the candidate manufacturing plan (4*) is modified (140) with the aim of improving the load-bearing capacity of the predefined region (1a).
(FR) L'invention se rapporte à un procédé (100) de production d'un plan de fabrication (4) destiné à la fabrication additive d'un objet (1) par impression 3D, ledit procédé comprenant les étapes suivantes : • un modèle tridimensionnel (2) de l'objet (1) à fabriquer est fourni (110) ; • pour au moins une région prédéfinie (1a) de l'objet (1), une contrainte mécanique (3) est spécifiée (120) avec une force et/ou un moment auquel cette région (1a) doit résister ; • pour au moins un plan de fabrication candidat (4*), une simulation est utilisée pour vérifier (130) si la région prédéfinie (1a) résiste à la contrainte prédéfinie (3) après la fabrication de l'objet (1) sur la base du plan de fabrication candidat (4*), ce plan de fabrication candidat (4*) spécifiant le matériau qui est ajouté à l'objet (1), l'emplacement et/ou le moment auquel ledit matériau est ajouté, et les paramètres de traitement sous lesquels ledit matériau est ajouté ; • en réponse à la région (1a) ne résistant pas la contrainte prédéfinie (3), le plan de fabrication candidat (4*) est modifié (140) dans le but d'améliorer la capacité de charge de la zone prédéfinie (1a).
