Title
(EN) SOLID FREE-FORM FABRICATION APPARATUSES AND METHODS
(FR) APPAREIL ET PROCEDE DE FABRICATION DE SOLIDES A FORME LIBRE
Abstract
(EN) Apparatuses and methods are described for supplying powder for solid free-form fabrication from a powder supply reservoir (2) that is movable from a servicing position to a dispensing position. The powder supply reservoir may be supported by a horizontally retractable support arm (4) . It may also be supported by a support pivot (22) , and the support pivot may comprise a horizontally retractable suport arm. These features add the convenience of permitting the powder supply reservoir to be serviced outside of a housing that encloses the solid free-form fabrication apparatus during the article-building operation.
(FR) L'invention concerne des appareils et des procédés d'alimentation en poudre pour la fabrication de solides à forme libre depuis un réservoir d'alimentation en poudre pouvant passer d'une position de service à une position de distribution. Le réservoir d'alimentation en poudre peut être porté par un bras de support rétractable dans le sens horizontal. Ledit réservoir peut également être porté par un pivot de support, lequel peut comprendre un bras de support rétractable dans le sens horizontal. Ces caractéristiques apportent davantage de commodité pour permettre audit réservoir d'alimentation en poudre d'être utilisé à l'extérieur d'un logement qui renferme l'appareil de fabrication de solides à forme libre pendant l'opération de fabrication d'articles.
