(FR) INSTALLATION DE FABRICATION ADDITIVE A BASE DE POUDRE A DISPOSITIF DE NETTOYAGE PAR RACLAGE
Abstract: front page image
(EN)The invention relates to a powder-based additive manufacturing unit (10) comprising a device (14) for layering the powder, which can be moved along a path connecting a start zone and an end zone. The layering device (14) comprises a powder-smoothing cylinder (36) for smoothing the powder disposed in a powder deposition zone (P) located between the start zone and the end zone. The unit (10) also comprises a cleaning device (90) located on the path of the layering device (14), said cleaning device (90) comprising scraper means (92) provided with a plurality of parallel scraper teeth (94) that scrape the surface of the smoothing cylinder (36) tangentially to said surface.
(FR)L'invention concerne une installation de fabrication (10) additive à base de poudre, comprenant un dispositif de mise en couche (14) de la poudre déplaçable le long d'un parcours reliant une zone de départ et une zone d'arrivée. Le dispositif de mise en couche (14) comprend un cylindre lisseur (36) de la poudre pour lisser la poudre disposée dans une zone de dépôt (P) de la poudre située entre la zone de départ et la zone d'arrivée. L'installation (10) comprend en outre un dispositif de nettoyage (90) situé sur le parcours du dispositif de mise en couche (14), le dispositif de nettoyage (90) comprenant des moyens de raclage (92) munis d'une pluralité de dents de raclage (94), parallèles entre elles, venant racler la surface du cylindre lisseur (36) de façon tangentielle à cette surface.
