REGION-BASED SUPPORTS FOR PARTS PRODUCED BY SOLID FREEFORM FABRICATION

Methods for generating supports (30) for parts (50) produced by solid freeform fabrication ('SFF') are disclosed. The method includes defining a plurality of layers (L) that make up the part, and for each layer, determining those regions (R) that require support. The method also includes m...

Zusammenfassung:	Methods for generating supports (30) for parts (50) produced by solid freeform fabrication ('SFF') are disclosed. The method includes defining a plurality of layers (L) that make up the part, and for each layer, determining those regions (R) that require support. The method also includes merging the regions for the different layers (L) into one or more common regions that require support, and providing at least one support for each of the one or more common regions. The result is that fewer supports are used as compared to conventional SFF fabrication methods. L'invention concerne des procédés permettant de générer des supports (30) pour des pièces (50) produites par fabrication de formes libres solides. Le procédé inclut la définition d'une pluralité de couches (L) qui constituent la pièce, et pour chaque couche, la détermination de ces zones (R) qui nécessitent un support. Le procédé inclut également la fusion des zones pour les différentes couches (L) présentes dans une ou plusieurs zones communes qui nécessitent un support, et la fourniture d'au moins un support pour chacune desdites une ou plusieurs zones communes. Le résultat est que moins de supports sont utilisés comparé aux procédés de fabrication de formes libres solides conventionnels.
