Abstract
(EN)
The present disclosure provides three-dimensional (3D) printing processes, apparatuses, software, and systems for the production of at least one desired 3D object. The 3D printer system (e.g., comprising a processing chamber, build module, or an unpacking station) described herein may retain a desired (e.g., inert) atmosphere around the material bed and/or 3D object at multiple 3D printing stages. The 3D printer described herein comprises one or more build modules that may have a controller separate from the controller of the processing chamber. The 3D printer described herein comprises a platform that may be automatically constructed. The invention(s) described herein may allow the 3D printing process to occur for a long time without operator intervention and/or down time.
(FR)
La présente invention concerne des procédés, des appareils, un logiciel et des systèmes d'impression tridimensionnelle (3D) pour la production d'au moins un objet 3D souhaité. Le système d'imprimante 3D (par exemple, comprenant une chambre de traitement, un module de construction ou un poste de déballage) de la présente invention peut conserver une atmosphère souhaitée (par exemple, inerte) autour du lit de matériau et/ou de l'objet 3D au niveau de multiples étages d'impression 3D. L'imprimante 3D décrite dans la description comprend un ou plusieurs modules de construction qui peuvent présenter un contrôleur séparé du contrôleur de la chambre de traitement. L'imprimante 3D décrite dans la description comprend une plate-forme qui peut être construite automatiquement. L'invention/les inventions décrite(s) dans la description peu(ven)t permettre la réalisation du procédé d'impression 3D pendant une longue période sans intervention de l'opérateur et/ou temps d'arrêt.
