Title
(EN) GENERATING BARRIERS IN ADDITIVE MANUFACTURING
(FR) GÉNÉRATION DE BARRIÈRES DANS LA FABRICATION ADDITIVE
Abstract
(EN)
An example of an additive manufacturing apparatus is disclosed. The apparatus comprises a process module to selectively treat a layer of build material from a build chamber formed from at least one sidewall and comprising a build platform moveable within the build chamber. The apparatus also comprises a powder distribution module to form a layer of build material in the build chamber. The apparatus further comprises a controller to receive data corresponding to an object to be generated and control the powder distribution module to form successive layers of build material on the build platform. The controller is further to control the process module to selectively treat portions of the formed layers to generate the object based on the received data and to generate the barrier based on the defined data.

La présente invention concerne un appareil de fabrication additive. L’appareil comprend un module de procédé pour traiter sélectivement une couche d’un matériau de construction à partir d’une chambre de construction formée d’au moins une paroi latérale et comprenant une plateforme de construction mobile à l’intérieur de la chambre de construction. L’appareil comprend également un module de distribution de poudre pour former une couche de matériau de construction dans la chambre de construction. L’appareil comprend en outre un dispositif de commande pour recevoir les données correspondant à un objet à générer et commander au module de distribution de poudre de former des couches successives de matériau de construction sur la plateforme de construction. Le dispositif de commande est en outre destiné à commander le module de procédé pour traiter sélectivement des portions des couches formées afin de générer l’objet sur la base des données reçues et pour générer la barrière sur la base des données définies.
