Abstract
La présente invention concerne divers objets tridimensionnels (3D), dont certains comprennent un fil ou un plan en 3D. L'invention concerne également des procédés, des appareils, un logiciel et des systèmes permettant leur production qui peuvent réduire ou éliminer la nécessité d'un support auxiliaire pendant la formation des objets 3D. Les procédés, les appareils, le logiciel et les systèmes de la présente invention peuvent permettre la formation d'objets comportant des structures de support auxiliaires espacées, en nombres réduits et/ou courtes. Ces objets 3D peuvent être des objets avec des surfaces adjacentes telles que des structures suspendues et des objets 3D creux plans.
