Title
(EN) DEVICE AND METHOD FOR PRODUCING A THREE-DIMENSIONAL WORKPIECE
(FR) DISPOSITIF ET PROCÉDÉ DE PRODUCTION D'UNE PIÈCE TRIDIMENSIONNELLE
Abstract
(EN)
We describe a process chamber, an apparatus, a modular system, a method, a safety device, a positioning system and a system for producing a three-dimensional workpiece and/or for use thereof when producing a three-dimensional workpiece. The process chamber for producing the three-dimensional workpiece via an additive layer construction method comprises: a material supply unit comprising a substantially ring-like shaped end portion at a first side of the process chamber, wherein the material supply unit is adapted to supply, via the end portion, material to a carrier on which the material is to be processed by the process chamber for producing the three-dimensional workpiece, and an opening at the first side of the process chamber for processing, by the process chamber, the material supplied on the carrier in order to produce the three-dimensional workpiece, wherein the substantially ring-like shaped end portion surrounds the opening.

L'invention concerne une chambre de traitement, un appareil, un système modulaire, un procédé, un dispositif de sécurité, un système de positionnement et un système de production d'une pièce tridimensionnelle et/ou d'utilisation de ceux-ci lors de la production d'une pièce tridimensionnelle. La chambre de traitement pour produire la pièce tridimensionnelle par l'intermédiaire d'un procédé de construction de couche additive comprend: une unité d'alimentation en matériau comprenant une partie d'extrémité de forme sensiblement annulaire sur un premier côté de la chambre de traitement, l'unité d'alimentation en matériau étant conçue pour acheminer, par l'intermédiaire de la partie d'extrémité, un matériau sur un support sur lequel le matériau doit être traité par la chambre de traitement pour produire la pièce tridimensionnelle, et une ouverture sur le premier côté de la chambre de traitement pour un traitement, par la chambre de traitement, du matériau amené sur le support afin de produire la pièce tridimensionnelle, la partie d'extrémité sensiblement de forme annulaire entourant l'ouverture.
