Beschreibung
Zusammenfassung:	Methods and systems for additive manufacturing are disclosed, the methods and systems comprising reducing the amount of support material used, by one or more methods, including inclusion of part material voxels and air voxels within the support regions, using a lattice of part material within support regions, printing one or more skin layers and boundary layers to support the part geometry and surface, and printing support layers in a drafted manner to reduce support material. La présente invention concerne des procédés et des systèmes de fabrication additive, les procédés et les systèmes comprenant la réduction de la quantité du matériau de support utilisé, par un ou plusieurs procédés, comprenant l'incorporation d'une partie de voxels de matière et de voxels d'air à l'intérieur des régions de support, à l'aide d'un réseau de matériau de partie à l'intérieur des régions de support, l'impression d'une ou plusieurs couches de peau et de couches frontières pour supporter la géométrie et la surface de la partie, et l'impression des couches de support d'une manière étirée pour réduire le matériau de support.
