| description | Embodiments of the systems and methods disclosed herein can related to an additive manufacturing process involving the use of an algorithm to determine the optimal build orientation of a build that will result in minimal thermal distortion during the build. The algorithm includes a momentum of inertia based objective function, wherein the output of the objective function can be used as a proxy for thermal distortion. In some embodiments, objective function can be configured as a mathematical matrix with mathematical variables modeling rotation angles of a build. The rotation angles can be in the x-, y-, and/or z- geometric planes of the build with respect to the build plate. An objective function output can be calculated for each iterative rotation. The minimum objective function output can be used as the rotation representing the orientation that would result in minimal thermal distortion.
Des modes de réalisation des systèmes et des procédés de l'invention peuvent être associés à un procédé de fabrication additive impliquant l'utilisation d'un algorithme pour déterminer l'orientation de construction optimale d'une construction qui conduira à une distorsion thermique minimale pendant la construction. L'algorithme comprend une fonction objective basée sur l'inertie de la fonction objective, la sortie de la fonction objective pouvant être utilisée comme proxy pour la distorsion thermique. Dans certains modes de réalisation, la fonction objective peut être configurée sous la forme d'une matrice mathématique avec des variables mathématiques modélisant des angles de rotation d'une construction. Les angles de rotation peuvent être dans les plans géométriques x, y et/ou z de la construction par rapport à la plaque de construction. Une sortie de fonction objective peut être calculée pour chaque rotation itérative. La sortie de fonction objective minimale peut être utilisée en tant que rotation représentant l'orientation qui conduirait à une distorsion thermique minimale. |
