Title
(EN) ADDITIVE MANUFACTURING OF INSULATING CONSTRUCTION ELEMENTS
(FR) FABRICATION ADDITIVE D'ÉLÉMENT DE CONSTRUCTION ISOLANTS
Abstract
(EN) The invention relates to a method for obtaining, by additive manufacturing, a construction element (1) comprising at least one structural element (2) and at least one insulating element (3, 4), wherein a dry mortar is mixed with mixing water so as to form a basic wet mortar, the basic wet mortar is transported to a printing head, and stacked layers of mortar are successively deposited by moving the printing head so as to form the at least one structural element (2) and the at least one insulating element (3, 4), the method being such that, before depositing the layers of mortar belonging to an insulating element (3, 4), an aqueous foam is additionally added to the basic wet mortar during the transport of the basic wet mortar to the printing head.
(FR) L'invention a pour objet un procédé d'obtention par fabrication additive d'un élément de construction (1) comprenant au moins un élément structurel (2) et au moins un élément isolant (3, 4), dans lequel on mélange un mortier sec avec de l'eau de gâchage de manière à former un mortier humide de base, on transporte ledit mortier humide de base vers une tête d'impression, et l'on dépose successivement, par déplacement de ladite tête d'impression, des couches de mortier superposées de manière à former ledit au moins un élément structurel (2) et ledit au moins un élément isolant (3, 4), ledit procédé étant tel qu'avant le dépôt des couches de mortier appartenant à un élément isolant (3, 4), on ajoute en outre une mousse aqueuse audit mortier humide de base lors du transport dudit mortier humide de base vers la tête d'impression.
