Definitions

  • multiple layers 210 of the build material 212 may include selected areas of coalesced build material 212, such that the selectively coalesced build material 212 in the layers 210 may be coalesced to form the 3D object or objects.
  • the coalescing agent 230 may enhance absorption of energy from an energy source (not shown) in the 3D fabrication system 200 to heat the build material 212 to a temperature that is sufficient to cause the build material 212 upon which the coalescing agent 230 has been deposited to melt, fuse, cure, sinter, cause a reaction with another material, or otherwise coalesce prior to or as part of being joined.

Abstract

Selon des exemples, un appareil peut comprendre un processeur et un support non transitoire lisible par ordinateur sur lequel sont stockées des instructions lisibles par machine qui peuvent amener le processeur à prédire, par l'application d'un modèle et avant la réalisation d'une opération de coalescence d'une partie d'un objet dans une couche de matériau de construction, un profil thermique de la couche de matériau de construction et il peut accéder à un profil d'image thermique de la couche de matériau de construction capturé après l'exécution de l'opération de coalescence dans la couche de matériau de construction. Les instructions peuvent également amener le processeur à déterminer un niveau de différence entre le profil thermique prédit et le profil d'image thermique capturé et à déterminer si le niveau de différence dépasse un seuil prédéfini. Les instructions peuvent en outre amener le processeur, sur la base du dépassement déterminé du seuil prédéfini par le niveau de différence déterminé, à déterminer que le matériau de construction comprend un matériau non conforme.
