Title (EN) ADDITIVE MANUFACTURING METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE FABRICATION D'ADDITIF
Abstract:
(EN) Additive manufacturing apparatus and method for producing an object layer by layer. The apparatus has a slurry applicator (5) for providing a layer of slurry (3) with a predetermined thickness (d1). The slurry (3) is a suspension containing a liquid and particles eventually forming the object, and has between 10 and 70volume % of particle content. A particle connection unit (7) is operative on the layer of slurry (3) to execute a single step particle connection process before applying a new layer of the slurry (3).
(FR) L'invention concerne un appareil de fabrication d'additif et un procédé de production d'objet couche par couche. L'appareil comporte un applicateur (5) de suspension pour la fourniture d'une couche de suspension (3) selon une épaisseur prédéfinie (d1). La suspension (3) est une suspension contenant un liquide et des particules formant finalement l'objet, et possède une teneur en particules entre 10 et 70 % en volume. Une unité de liaison (7) de particules est destinée à exécuter, sur la couche de suspension (3), un procédé de liaison des particules en une seule étape avant l'application d'une nouvelle couche de suspension (3).
