Title
(EN) TRANSLATING CONTENTS OF A PRINT CHAMBER TO A SECONDARY CHAMBER
(FR) TRANSLATION DE CONTENUS D'UNE CHAMBRE D'IMPRESSION VERS UNE CHAMBRE SECONDAIRE
Abstract
(EN)
A platform is moved to translate contents of a print chamber to a secondary chamber. Negative pressure is applied to the secondary chamber and print chamber during motion of the platform, to reduce friction between the contents of the print chamber and sidewalls of the print chamber.
(FR)
Une plateforme est déplacée pour effectuer la translation des contenus d'une chambre d'impression vers une chambre secondaire. Une pression négative est appliquée à la chambre secondaire et à la chambre d'impression pendant le mouvement de la plateforme, afin de réduire le frottement entre les contenus de la chambre d'impression et les parois latérales de la chambre d'impression.
