Beschreibung
Zusammenfassung:	The present invention relates to a process of fabricating a multi-layer composite structure by 3D printing, said composite structure comprises at least one cured mortar layer formed by curing of a mortar composition, and at least one polyurethane layer formed by polymerization of a first polyurethane forming composition, wherein said mortar composition and said first polyurethane forming composition are dispensed individually and simultaneously via adjacent printing nozzles. The mortar composition is optionally modified by a second polyurethane forming composition. La présente invention concerne un procédé de fabrication d'une structure composite multicouche par impression 3D, ladite structure composite comprenant au moins une couche de mortier durci formée par durcissement d'une composition de mortier, et au moins une couche de polyuréthane formée par polymérisation d'une première composition de formation de polyuréthane, ladite composition de mortier et ladite première composition de formation de polyuréthane étant distribuées individuellement et simultanément par l'intermédiaire de buses d'impression adjacentes. La composition de mortier est éventuellement modifiée par une seconde composition de formation de polyuréthane.
