Computer Graphics Forum 33, 6, 322–332) A method proposed by others in 2014, considering how to better decompose the model can make the alignment result better. The method first extracts the surface shell of the model, and does not process it for the solid model. Then, the extracted shell model is tetrahedralized and then adopted. The bottom-up search strategy first decomposes the model and then uses the blocks obtained by the decomposition to arrange.
  • a model decomposition and alignment method for 3D printing comprising the following steps:

Abstract

L'invention concerne un procédé de décomposition et d'arrangement de modèle destiné à l'impression 3D, comprenant : soit un modèle S et un espace d'impression PV, calcul d'une décomposition en blocs d'attribut de pyramide initiaux du modèle S et exécution d'une voxélisation sur ces blocs d'attribut pyramidaux pour générer une première solution intermédiaire initiale isolu0 ; initialisation d'un ensemble de solutions intermédiaires ISolu ＝ {isolu0} ; initialisation d'une solution complète optimale P* ; pour ce qui concerne chaque solution intermédiaire isolii dans l'ensemble de solutions intermédiaires ISolu, calcul d'une série de solutions intermédiaires candidates générées par la solution intermédiaire et résolution d'une solution optimale de décomposition et d'arrangement du modèle S ; et exécution d'une optimisation locale sur un maillage tridimensionnel d'une pluralité de blocs extraits et, par translation de chaque bloc dans le sens négatif de l'axe Z, arrangement ces blocs de manière plus compacte, ce qui permet d'obtenir la décomposition et l'arrangement optimaux pour ce qui concerne le modèle S. Un modèle est décomposé en moins de blocs de manière à être disposé de manière efficace dans un espace d'impression, ce qui permet d'exécuter le processus d'impression efficacement.
